The findings don’t suggest laughter is a cure-all. What they do suggest is something more useful for everyday life: laughter is a low-cost, low-risk way to nudge the nervous system out of threat mode and back toward regulation — especially when it’s shared with other people.

How Laughter Works

When you laugh, you’re not only reacting emotionally — you’re recruiting multiple systems at once. Your breathing changes (often becoming deeper and more rhythmic), your face and core muscles contract, and your autonomic nervous system (the system that controls “fight-or-flight” and “rest-and-digest” can shift gears. That matters because so many stress-related problems — poor sleep, tension, irritability, rumination — ride on chronic activation of the stress response.

One of the most consistent biological signals researchers track is cortisol, a stress hormone that tends to rise with ongoing strain and can affect sleep, immune functioning, and mood. A meta-analysis found that spontaneous laughter was associated with greater reductions in cortisol than usual activities, suggesting a genuine stress-regulation effect rather than just a subjective feeling of relief.

This is important because it ties the “I feel better” experience to a measurable stress marker. So it’s not all in your head because it is biologically measurable. If you want to think of it another way, laughter is the non-prescription medication that you should take as often as possible. I’ve written about this before and have recommended it to all my college students and my patients.

I am a great believer that laughter plays a significant role in our lives. And you don’t need to wait to be in a group to laugh, because laughing even while alone serves a superior purpose in health maintenance. Does that mean you spontaneously laugh out loud for no reason? It could be so, but you could also use things like TV shows, films, things you’ve read, or anything that is humorous and makes you laugh.

Laughter can also influence brain chemistry linked to mood and pain. While the exact pathways are complex, reputable clinical education sources point to laughter’s relationship with endorphins and other neurochemicals involved in well-being and reward. That doesn’t mean laughter replaces medication or therapy when those are needed. But it helps explain why, in the moment, laughter can feel like a small reset — less tightness in the chest, a clearer head, a slight loosening of emotional grip.

There’s also a social pathway that may be just as powerful. Laughter is contagious for a reason: it signals safety and shared understanding. When people laugh together, they often feel more connected, and that sense of belonging can buffer stress. A 2023 Harvard Gazette feature — grounded in clinical expertise — highlights laughter’s role in lifting spirits and strengthening connection, which aligns with what many mental health clinicians see in real life: isolation amplifies distress, and connection softens it.

What Current Studies Say

The strongest modern evidence comes from controlled “laughter-based interventions.” These include laughter therapy, humor interventions, and laughter yoga (which combines intentional laughter with breathing and simple movement). These approaches are especially useful for research because they can be delivered consistently and compared with control conditions.

Mental health outcomes are promising, though not uniform across every study. A 2024 meta-analysis of randomized controlled trials examined laughter and humor interventions in adults and found improvements in outcomes such as depression and sleep, with more mixed findings for anxiety depending on the population and the type of intervention. That pattern — clearer benefit for mood and sleep than for anxiety — shows up elsewhere too.

For example, a 2022 randomized study on online laughter therapy in first-year nursing students reported reductions in depression, while anxiety effects were less consistent. This doesn’t mean laughter can’t help anxiety. It suggests that anxiety may require either longer interventions, more targeted techniques, or additional supports (like cognitive strategies and exposure-based tools), whereas mood and sleep may respond more readily to the stress-relief and social “unclenching” that laughter provides. There are benefits, and there are limitations, but I suggest the benefits are worth trying.

On the physical side, one area getting attention is cardiovascular functioning. A well-known line of research has explored how laughter may influence blood vessel function and circulation — factors linked with heart health. A British Heart Foundation article discussing this body of work describes findings such as improved arterial function and reduced inflammation markers following laughter-based approaches. Even when studies are small, the direction of effect is noteworthy because cardiovascular health is so closely tied to stress physiology. Worried a bit about your heart health? Okay, then you have to try laughing.

Workplace and burnout-related outcomes have also been studied. A 2024 systematic review focused on nurses and nursing students reported that laughter yoga interventions were associated with reductions in stress and burnout measures, along with improvements in mood-related outcomes in several included studies. These are high-stress groups, so the fact that laughter-based practices can move the needle at all suggests they may be a helpful “adjunct” — a supportive add-on rather than a standalone solution.

One caution that shows scientific maturity in this field is that researchers are increasingly clear about limits. A review on laughter and longevity argues that laughter is biologically plausible as a supportive factor — through stress modulation, social connection, and healthier behavioral patterns — but also emphasizes that the science is still developing and needs stronger, larger trials. That’s the responsible takeaway: laughter looks beneficial, especially for stress and mood, but it’s not magic, and it’s not a substitute for medical or psychological care.

Making Laughter a Health Habit

If laughter is “medicine,” it’s not a pill — it’s a behavior. And like most health behaviors, it works best when it’s realistic, repeatable, and emotionally safe.

Start by letting go of the idea that you must feel joyful first. Some laughter-based methods use intentional laughter that can become genuine once the body loosens up. This can be useful for people who feel flat, burnt out, or socially guarded. In a sense, it’s similar to other behavioral activation ideas: you don’t wait for motivation; you create conditions that make a better mood more likely. Research on structured laughter interventions suggests that even planned laughter can improve well-being.

Next, focus on the social dose. Watching something funny alone can help, but shared laughter adds warmth, belonging, and the quiet reassurance of “I’m not doing life by myself.” If someone is depressed, grieving, or chronically stressed, that social signal may be part of the benefit, not just the joke itself.

Finally, keep it grounded. Laughter is not appropriate in every moment, and forcing it in the face of serious pain can feel invalidating. A helpful guideline is to use laughter as a release valve, not a way to deny reality. It can sit alongside hard feelings rather than replacing them. And if laughter triggers discomfort — some people feel vulnerable when they laugh freely — gentle exposure is fine: smaller moments, safer people, and content that doesn’t leave you feeling ashamed afterward.

Taken together, the current research implies something simple: laughter is a meaningful stress-buffer with measurable biological signals, credible mental health benefits (especially mood and sleep), and potential cardiovascular upside — most effective as a complement to good care and good habits, not a replacement for them.

America’s AI Action Plan, recently announced by the Trump Administration, aims to achieve U.S. dominance in artificial intelligence but overlooks a key force multiplier: investing in the American people’s human brainpower. From design to deployment, AI systems reflect and rely on the cognitive capacities of the people who build and use them. 

American ingenuity—what Lincoln called ‘the fire of genius’—has long been the engine of our productivity and progress. From the space race to Silicon Valley, it’s not just natural resources or industrial capacity that set the U.S. apart, but the cognitive, creative, and entrepreneurial capacity of our people – our brain capital.

The Administration’s stated aim of “powering a new age of American leadership in science, technology, and global influence” will not be achieved by silicon and data infrastructure alone. It must be accompanied by investments in a different kind of infrastructure – our national brain infrastructure.

Just as AI relies on chips, cloud networks, and compute power, its success ultimately depends on the human intelligence that shapes, governs, and applies it. The World Economic Forum has identified the capabilities most essential in the AI era: analytical thinking, resilience, creativity, empathy, and curiosity. These are not technical upgrades – they are human ones. Failing to build brain infrastructure means our most powerful tools may evolve faster than our capacity to direct them.

Despite enormous advances in neuroscience, the brain remains one of the least understood organs in the human body. We know that brain health and performance is shaped by everything from genetics and inflammation to early life experiences and social connection, but we lack a full understanding of how these factors interact—or how to intervene most effectively across populations. Rising rates of mental and neurological health conditions are eroding America’s cognitive resilience – threatening our nation’s capacity to learn, work, innovate, and lead. Further, we know very little about how AI itself may reshape our ability to do these things.

While the U.S. is slashing strategic investments in science, education and health, other nations are doubling down. China, for example, has dramatically expanded its national brain science agenda—accelerating brain-computer interface trials, funding neuro-AI innovation, and integrating neuroscience into its economic and defense strategies.  If America fails to act, it risks ceding not just scientific leadership, but the very foundation of AI competitiveness.

To compete with China and lead the next era of innovation, the U.S. must go beyond chips and deregulation. As many European nations already are developing, the United States needs a national brain capital strategy – a Human Intelligence “H.I.” Action Plan – that will enable us to fully flourish and lead.

Any strategy to power a new age of American leadership must expand the aperture beyond the technology that aids us – to include us. This involves prioritizing early child development and strong education systems, and embedding neuroscience-informed learning in schools. It also requires us to address the health and social risk factors that hamper cognitive resilience, scale cognitive capacity across the workforce through tools, culture and design, incentivize brain health innovation across sectors, and address rising rates of mental and neurological health conditions that plague Americans at all ages.

There is no doubt that AI holds the promise of augmenting and accelerating human productivity and scientific discoveries. But we must remember this is a collaboration. Investing in AI without equally investing in human capacity, ethics, and well-being risks collapsing the very foundation we aim to build. By nearly every meaningful measure – life expectancy, happiness, living standards, equality, cognitive resilience – Americans are falling behind. Our technological ambition must be matched by a human one.

The bottom line: we cannot build intelligent systems without fueling human intelligence. The countries that win the AI age will be those that invest not only in machines – but in the cognitive, emotional, and creative capacity of their people.

In Malaysia, I ate like a poet unchained.

Noodles in the morning.

Spiced broth at noon.

Chicken glazed with soy and garlic by nightfall.

I sat on plastic stools under humming fans.

I picked up late-night snacks from carts where the only menu was memory and steam.

I ate more than usual.

I felt full every day.

But when I returned home, the scale surprised me.

Two pounds lighter.

My steps had not changed.

My sleep was the same.

I tracked nothing.

I restricted nothing.

Yet somehow, my body felt clearer, lighter, and calmer.

That was the moment I understood.

The issue was not how much I had been eating.

It was what I had been eating.

Here’s the bar of my Penang hotel:

The Research Now Makes It Obvious

A major review published in Nature Reviews Endocrinology confirmed what I had already suspected.

Ultra-processed foods, often called UPFs, are not just harmless conveniences.

They actively promote overeating, disrupt metabolism, and increase the risk of obesity and chronic disease.

Researchers reviewed decades of data.

Their conclusions were clear:

• UPFs override your sense of fullness
• They damage the gut microbiome
• They interfere with hormones like insulin and leptin
• They promote chronic inflammation
• They increase the risk of early death

These are not neutral calories.

They are chemical provocations.

.

From Preservation to Manipulation

A century ago, food processing helped prevent disease.

Preservatives and fortification solved real problems like spoilage and vitamin deficiencies.

But today’s ultra-processed foods are something else entirely.

They are stripped of fiber and water.

They are saturated with sugar and salt.

They are softened or crisped for speed.

They require little chewing and deliver maximum pleasure in minimal time.

These are not foods made to nourish.

They are products made to disappear.

What I Noticed in Malaysia

In Penang and Singapore, I kept waiting for the usual signs.

Cravings.

Energy crashes.

That pull toward sugar at night.

None of them came.

Instead, I ate whole and real foods.

Greens stir-fried in oil.

Fish with bones intact.

Rice, fruit, spice, and broth.

Even the desserts had substance.

Even the snacks had structure.

And every bite required chewing.

What Ultra-Processed Foods Really Do

The review and related studies show that UPFs:

• Speed up how fast we eat
• Bypass satiety signals
• Starve the beneficial bacteria in the gut
• Trigger a hormonal imbalance
• Promote low-grade inflammation
• Crowd out nutrient-rich foods

One U.S. study linked high UPF intake to more than 120,000 preventable deaths each year.

Another found strong associations with cardiovascular disease, type 2 diabetes, and cognitive decline.

This finding is not just about gaining weight.

It is about how these foods affect nearly every system in the body.

Labels Lie. Chemistry Tells the Truth.

UPFs often pretend to be healthy.

They say low-fat, gluten-free, plant-based, or high-protein.

But flip the package and the label tells a different story.

You’ll find artificial flavors, gums, starches, stabilizers, and sweeteners you can’t pronounce.

You’ll find them in:

• Protein bars
• Ready-to-drink shakes
• Flavored yogurts
• Cereal with cartoon characters
• Shelf-stable snacks that never spoil

These foods don’t just deliver calories.

They confuse your hunger.

They dull your instincts.

They keep you coming back.

What I Now Tell My Patients

Instead of strict food rules, I offer simple replacements.

• Eat foods with fewer than five ingredients
• Choose oats over cereal
• Choose fruit over a bar
• Choose nuts over crackers
• Cook when you can, even if it’s just olive oil, garlic, and greens

Real food asks you to chew.

It slows you down.

It satisfies you in a way engineered foods cannot.

You don’t need to be perfect.

You only need to shift direction.

Letting Go Is Hard for a Reason

Manufacturers design ultra-processed foods to be addictive.

They melt in your mouth.

They hit the same reward centers as nicotine.

They are easy to chew and hard to resist.

They make you eat faster and feel less full.

This is not a failure of willpower.

This is a feature of the product.

Start small:

• Replace soda with sparkling water and lime
• Prep one simple meal a week
• Add a vegetable to each dinner
• Keep one snack unprocessed

The smallest shift creates momentum.

And momentum is what makes change last.

Final Thoughts: Hunger Is a Signal

In Malaysia, I stopped thinking about food.

I didn’t count macros.

I didn’t obsess over protein.

I ate when I was hungry and stopped when I was full.

Because the food I was eating allowed me to stop.

When I walked through the airport food court back home, everything looked different.

It wasn’t the smell that hit me.

It was the stillness.

The silence.

The lifelessness of boxes filled with shelf-stable meals and snack bars designed by chemists, not chefs.

And I realized something.

Hunger is not always a request for food.

Sometimes, it is a call for something real.

I came to Borneo to let the ground fight back.

This morning, outside Kota Kinabalu, Malaysia, my boots slipped on a tangle of wet roots.

The air smelled of earth and rain.

A quiet hum of life surrounded me.

In that awkward, humbling stumble, I felt something rare:

My body woke up.

The Comfort Trap That’s Making Us Weak

In Seattle, I walk sidewalks and treadmills — smooth, safe, and sterile.

For most of human history, humans moved across shifting ground.

Forests. Fields. Hills.

Every step required micro-adjustments.

Your feet, ankles, and hips worked together without your conscious effort.

But today?

Flat concrete. Cushioned shoes. Escalators and elevators.

The result?

• Weak stabilizer muscles in the feet and ankles
• Poor balance and slower reaction times
• A brain that tunes out during your most basic movement

Comfort stole our strength.

What Science Says About Uneven Ground

Clinical studies confirm what my jungle stumble reminded me:

Walking on uneven terrain:

✔️ Activates foot and ankle stabilizers
✔️ Improves proprioception (your body’s sense of position in space)
✔️ Sharpens reaction time
✔️ Reduces fall risk in older adults
✔️ Boosts mood and cognitive performance

A 2021 study found that older adults walking on rough paths improved their gait stability by 22%.

A separate trial revealed that rugged walking improved working memory and decision-making speed.

In other words: Your steps train your brain.

Orangutans, Cobras — and the Gift of Paying Attention

I paused beneath the jungle canopy.

An orangutan swung overhead, effortless in its grace.

It stared at me as if to say, “You humans forgot how to move.”

A rustle in the underbrush.

Was it a cobra? A monkey?

Or just the wind reminding me to stay alert?

Either way, I wasn’t scrolling my phone.

You can’t walk distracted when the jungle might bite back.

Uneven ground forces presence.

And in a world addicted to autopilot, presence is a rare medicine.

Rough Terrain Rewires Your Brain for Survival

I used to think walking was the ultimate autopilot activity.

But neuroscience says otherwise.

Rough terrain lights up your prefrontal cortex — the part of your brain that handles attention and planning.

Your cerebellum and sensory nerves work overtime to keep you upright.

This sparks:

• Lower cortisol (stress hormone)
• Improved heart rate variability (a marker of resilience)
• Faster reflexes when life throws you off-balance

One landmark study found these brain benefits last long after the walk ends.

So the next time your foot meets uneven ground, know this:

Your brain is rebuilding itself, one step at a time.

Flat Surfaces Make Life Easy — and Make You Fragile

Modern life has flattened our world.

We walk in shoes that numb the sensation.

On surfaces designed to eliminate surprise.

And then we wonder why our balance fades with age.

Falls are the leading cause of injury-related death in people over 65.

However, the danger begins decades earlier, when our feet stop adapting and our brains stop noticing.

How I Brought This Home

Back in Seattle, I made some simple shifts:

✔️ I walked forest trails instead of smooth streets.
✔️ Hiked on pebble beaches where every step shifted.
✔️ Walked barefoot on grass during morning routines.
✔️ Kept a wobble board under my standing desk.
✔️ Balanced on sidewalk curbs instead of staying in the middle of the path.

Small, daily friction makes your body strong again.

And one more thing — stay safe.

Choose trails appropriate for your skill level, watch your footing, and skip barefoot walking where sharp rocks or hidden hazards could cause injury.

How to Start (No Jungle Required)

Here’s how I coach patients and friends to rebuild strength and balance:

✔️ Choose uneven surfaces: dirt trails, grassy parks, rocky beaches, or mulch paths.
✔️ Go barefoot (when safe): start on grass, packed earth, or soft sand.
✔️ Slow your pace: give your body time to adapt.
✔️ Add balance drills: balance on logs, low curbs, or balance cushions indoors.

You don’t need to overhaul your life.

But you do need to stop walking only on flat, predictable ground.

Adaptation is the Goal — Not Perfection

The real danger isn’t falling.

It’s losing your ability to adapt.

On uneven ground, your body learns to adjust.

Your brain stays alert.

Your nervous system sharpens.

It’s not about avoiding every stumble.

It’s about responding better when you do.

What Happens If You Ignore This?

If you wait until your balance is depleted, regaining it becomes harder.

The loss happens slowly:

• Your stabilizer muscles atrophy.
• Your reaction time slows.
• Your confidence erodes.

But rebuilding is simple.

Step off the pavement.

Find a trail.

Let the ground challenge you again.

Of course, be safe and don’t take unnecessary risks.

Final Thoughts: What the Jungle Taught My Feet

By the end of my hike, my legs were burning, and my boots were caked with mud.

But my mind felt clearer than it had in months.

Maybe this is what we’re wired for:

Not flat streets. Not endless comfort.

But uneven steps that challenge and strengthen us.

Modern life has made our paths smooth.

But with a little intention, we can rebuild what we lost — balance, strength, awareness.

And maybe, in the process, discover something deeper than comfort:

Vitality.

No phone.

No watch.

No distractions.

Just her presence — so quiet, it filled the room.

She had metastatic cancer, but that wasn’t what she came to talk about.

“I spent my whole life moving,” she said. “Rushing, fixing, solving. Even when I sat still, my mind didn’t stop. But cancer… cancer taught me something else.”

“It taught me how to be still.”

She didn’t say it with resignation. It felt like a victory.

Most people come into the clinic with questions about what to do.

They want a treatment plan, a supplement list, a way forward.

She came in with something simpler, and somehow, deeper — a way to be.

“I used to think stillness was laziness,” she told me.

“But now I think it’s wisdom. Sitting in the garden with my tea, letting my dog nap beside me.”

No music.

No news.

Just being there.

“That,” she said, “was the first time I really lived.”

She wasn’t being poetic.

She was just telling the truth.

Stillness

Stillness is a challenging concept to sell in our culture.

We equate motion with progress.

We blur productivity and purpose.

We fill every space with noise.

But healing, aging, grieving, and loving — all require stillness.

I’ve seen patients search for answers in pills, scans, and data.

But sometimes the answer comes in silence.

A deep breath.

A quiet morning.

A patient who learned to stop chasing life long enough actually to feel it.

She asked me no questions.

She just said thank you.

And as she left, I realized I was the one who’d been given something.

Final Thoughts

I’ve met thousands of patients.

But the ones who stay with me are rarely the ones who fought the hardest or read the most studies.

They’re the ones who discovered a truth we forget in our rush: That stillness isn’t the opposite of life.

It’s the quiet space where life shows up.

Higher scores for diet quality and greater consumption of shortfall nutrients, especially nutrients of public health concern, are associated with dietary patterns that are rich in canned and dry beans. Improved weight-related outcomes are also linked to bean dietary patterns. In essence, dietary recommendations for the United States should consider the nutritional and health advantages of encouraging more people to eat canned and dry beans.

But plant-based diets have some benefits that may surprise many. Reduced mortality from prostate cancer and improved ecological sustainability are only two of the several advantages of plant-based diets.

According to a recent study conducted by academics, beans and peas are the most cost-effective and environmentally friendly alternatives to meat and milk. Given the current emphasis on environmental and climate change, we must consider alternatives to our current meat-based diet and assess their value.

The study published in the PRNAS found that soybeans, peas, and beans, as well as other legumes, performed better than processed foods like veggie burgers and plant milks.

Even after considering possible savings and investments, lab-grown meat was the most ineffective substitute due to its expensive price tag and the absence of health advantages.

What’s This About “Pulses?”

Pulses have become less common in people’s everyday diets and the prevalence of chronic diseases has increased during the last century, both of which have altered people’s eating patterns. Whole grain and legume consumption is associated with improved cardiovascular, metabolic, and cognitive health as well as longer life expectancy, according to both a priori and a posteriori dietary patterns. Contrarily, cardiovascular disease and premature death have been linked to diets heavy in sugar, processed foods, and red meat.

Some examples of pulses are peas, beans, and lentils. As an illustration, while pea pods are legumes, the peas within them are the pulse. While most of us eat legumes for their seeds or pulses, the whole plant is used in agriculture for cover crops, cattle feed, and fertilizers. Pulses include beans of many varieties, including kidney, black, pinto, navy, chickpeas, and many more. (This information was sourced from: https://nutritionsource.hsph.harvard.edu/legumes-pulses/). But pulses aren’t the only thing to consider. For example, beans are “resistant starches” and that is the importance they bring to our diet.

Everyday foods often contain starch, a type of carbohydrate. After cellulose, it is the chemical component found in plants in the highest abundance. In its chemical form, starch consists of two molecules of monosaccharide. Starch falls into one of three types according to its physical and physiological characteristics: quickly digestible, slowly digested, or resistant starch. It was also discovered that resistant starch remained undigested. Research has shown that the gut microbial communities make use of these undigested carbohydrates. Here is where all the magic starts.

Resistant starch does not produce an increase in blood sugar levels since it is not broken down in the small intestine. Beneficial bacteria proliferate while harmful bacteria deplete as a result of fermentation in the large intestine, leading to an improvement in gut health. Glycemic management (especially important for diabetic patients) can be enhanced by promoting healthy gut bacteria. A reduction in cholesterol levels and the danger of colon cancer are among the other advantages of resistant starch. It also helps with constipation and both treats and prevents it. Because of its long fermentation process, resistant starch produces less gas than other fiber types.

Our best sources of resistant starch foods include:

• Plantains and green bananas (as a banana ripens, the starch changes to regular starch)
• Beans, peas, and lentils (white beans and lentils are the highest in resistant starch)
• Whole grains, including oats and barley
• Cooked and cooled rice. Why “cooled” rice? Because it increases the resistant starch content.

So, beans aren’t the only food with resistant starch qualities, but they are the easiest to obtain and least expensive when prepared in dried form. Canned beans may seem fine for quick meals, and that’s true, but they also may contain high levels of salt, which is unsuitable for anyone’s diet.

Concerned about your health and that of the plant? Reconsider a plant-based diet and beans as a staple in your meals.

Left-handedness has long posed a challenge in many cultures, as nearly everything has been designed for right-handed individuals. I also have a relative who is left-handed, and the school saw no issues in that regard. He was an excellent student, graduated with top grades, and went on to a professional school where he had to use specialized instruments. The issue? Most of the instruments were, once again, designed for right-handed users.

He struggled significantly to find left-handed instruments, and he wasn’t alone. I also had a friend who was left-handed and enjoyed playing golf. Most golf equipment is similarly designed for right-handed players. Again, he faced difficulty finding left-handed golf clubs. But one time, he had a great chuckle when someone stole his golf clubs from the trunk of his car. “I wonder how surprised they’re going to be when they find out they can’t use those clubs because they’re made for a left-handed golfer,” He said with a glorious smile on his face.

Have you ever tried using your opposite hand to perform your daily activities? Do you believe that training your non-dominant hand can open up new creative channels or stimulate old, dormant brain regions? Recent studies show that the benefits of non-dominant hand training might be more useful than previously thought, yet more complex.

Have you ever thought about what would happen if you started using your “other” hand for everyday activities? Perhaps you have heard claims that training your non-dominant hand can unlock hidden creativity or tap into unused parts of your brain. The reality is more complex than these claims, but recent research has provided some interesting insights into what happens when we try to use our non-dominant hand.

What the Science Shows

The idea that using your non-dominant hand will suddenly make you more creative is largely a myth. As researchers have found, while blogs and self-help articles often promise dramatic cognitive boosts, the scientific evidence tells a different story. Any improvements you gain will likely be specific to the skills you practice, rather than providing a general creativity enhancement.

Actual Changes in Your Brain

When you persistently train your non-dominant hand, measurable changes occur in your brain. Studies using advanced brain imaging have shown that sustained practice with your non-dominant hand creates new neural pathways and strengthens existing ones. This process, called neuroplasticity, demonstrates your brain’s remarkable ability to adapt and reorganize itself.

For example, research on precision drawing with the non-dominant hand revealed increased functional connectivity among various brain regions involved in hand control and movement planning. Similarly, studies on learning to use chopsticks (granted, most of us rarely use chopsticks) with the non-dominant hand showed significant changes in brain activity patterns after just a few weeks of practice.

A Possible Schedule to Use

The following is based on research in this area, but it serves as a simple and potential guide for anyone who wants to test some of the research theories. This is not a specific training program for anyone, but a more recreational activity. Remember that research always has imperfections, and some of these results are due to the samples used, the areas where it was conducted, and the researcher’s own biases.

Training your non-dominant hand requires a structured approach, which begins with fundamental skills before advancing. If you think you will be turned into a Picasso or a best-selling author because of these exercises, you may be disappointed. There was only one Picasso, but you can possibly improve some things for yourself. Exactly what they will be, at this point, is an unknown. Daily practice of 15–20 minutes may lead to enhanced abilities.

Start with the basics (Weeks 1–2)
Write your name slowly with your non-dominant hand, followed by practicing the alphabet and basic words. The initial appearance of your writing does not need to be perfect. Back to that time in elementary school when you were first learning your alphabet, and how your handwriting had to be improved by repeatedly drawing circles and then letters. Using the non-dominant hand will be very much like the initial learning. This is the handwriting part of your exercise.

Now, draw basic shapes, including circles and lines, while concentrating on maintaining control rather than achieving perfection. The initial exercises help your brain learn fundamental motor patterns, which serve as a foundation.

Move into daily life (Weeks 3–4)
After gaining control of your writing movements, begin using your non-dominant hand for basic everyday activities. Begin by using your non-dominant hand to hold your coffee cup and use a spoon to eat during meals, starting with basic foods.

Do not attempt this while using hot liquids or foods in your non-dominant hand. We don’t want anyone to have an unpleasant experience. So, care is the watchword here. Spend daily intervals with your computer mouse positioned on the opposite side of your normal use. This technique helps you connect your practice sessions to actual, real-world applications.

Refine your skills (Weeks 5–8)
Progress to performing more accurate tasks with your non-dominant hand. The activities you should attempt next include threading needles, using scissors for basic cuts, and brushing your teeth. Add creative elements too — spend time drawing, painting, or playing instruments if you have them.

Master advanced coordination (Week 9+)
The last step involves performing complex tasks that will push your abilities to their limits. The brain development process benefits significantly from learning to use chopsticks, while activities like playing catch and writing whole paragraphs integrate all your learned skills. Progressively incorporate your non-dominant hand into your hobbies, cooking activities, and problem-solving tasks. But always proceed cautiously with every activity in which you will engage.

Will this program work for you? Only you can make that determination, and you are also the one who will decide whether you want to engage in this activity. It might be interesting, it might be useful, or it might be something you decide to toss aside. No harm.

It’s a brilliant question — practical, personal, and rooted in lived experience.

We’ve all been there: eating blueberries, sipping matcha, nibbling dark chocolate, hoping it’ll offset the chaos of our lives.

We’re told that foods like blueberries are miracle cures — that if we just eat clean enough, we can outrun stress.

But here’s what I’ve seen in practice:

You can’t eat your way out of chaos.

Still, food matters. Deeply.

Let’s unpack what antioxidant-rich foods can do for a burned-out brain — and where their power ends.

(P.S. That “Let food be thy medicine” quote? Not really Hippocrates.)

What Are High-ORAC Foods, Anyway?

ORAC, short for Oxygen Radical Absorbance Capacity measures how well a food can neutralize free radicals (unstable molecules that damage cells, accelerate aging, and promote inflammation).

Some of the highest-ORAC foods include:

These are some of the most evidence-based foods that fight burnout by countering oxidative stress and inflammation.

Consuming these foods regularly can make your body more efficient at extinguishing the “metabolic fires” triggered by stress, poor sleep, and inflammation.

So yes, these foods help.

But they’re not enough.

Stress, Sleep, and the Limits of Diet

Take a real-world example:

A 49-year-old entrepreneur came to me burned out.

She exercised.

Ate mostly plants. Drank matcha. Took magnesium.

Still exhausted. Irritable. Foggy.

Why?

She was sleeping five hours a night, answering emails at midnight, skipping meals, and never pausing.

Her nervous system was locked in a state of fight-or-flight.

And even the most antioxidant-rich foods won’t restore the parasympathetic state we need to digest, repair, and think clearly.

Nutrition supports healing, but it doesn’t initiate it when the system is overloaded.

What Antioxidants Can Do

So what can antioxidants do?

A nutrient-dense, antioxidant-rich diet can help:

• Lower CRP (a marker of inflammation)
• Improve cognition under stress.
• Stabilize mood via the gut-brain axis.
• Protect mitochondria from oxidative stress.
• Support neurogenesis (yes, new brain cell growth)

These are some of the most powerful antioxidant benefits for the brain — and they’re magnified when paired with rest and rhythm.

One 2023 study found that a Mediterranean-style, antioxidant-rich diet was linked to a lower risk of depression.

Another study showed that people who consumed more polyphenol-rich foods had better memory scores, regardless of their sleep quality.

The takeaway? Antioxidants can buffer the damage. But they can’t reset the machine.

What They Can’t Do

Let me be direct:

No number of blueberries can fix:

• Poor sleep hygiene
• Work addiction
• Emotional suppression
• Constant digital overload

Clean eating can quietly backfire — especially when it becomes a way to control life instead of nourish it.

Food is a foundation, not a fix.

What Actually Works (In Real Life)

Here’s what I tell patients when they’re doing all the “right” things — but still feel off:

1. Anchor meals to rhythm, not mood

Eat at consistent times daily. This stabilizes your gut clock and supports digestion.

2. Start the day with color

Aim for 3+ natural colors before noon: blueberries, spinach, turmeric, red pepper.

3. Pair food with ritual

Eat away from screens. Use real dishes. Go outside if you can. This activates your parasympathetic system.

4. Don’t supplement stress away

Magnesium, ashwagandha, resveratrol — all useful. But only after the basics are covered: sleep, movement, light, and breath.

5. Get morning light every day

Even 10 minutes of sunlight in the first two hours after waking can reset your circadian rhythm, improve sleep, and reduce stress reactivity.

Rhythm Over Rescue

Here’s the core truth:

Health isn’t about rescue. It’s about rhythm.

We chase the perfect food, supplement, or hack to undo imbalance.

But the body doesn’t crave intensity.

It craves consistency.

Yes, antioxidant-rich foods help.

But when food is paired with consistent rest, movement, morning light, connection, and meaning?

That’s when transformation happens.

A Series for the Questions That Matter

Reader questions shape how I practice medicine — and how I write.

If this one resonates, know this:

You’re not alone. Many of you are doing the right things, just in the wrong context.

You can eat perfectly and still feel off.

When food becomes a companion to healing, not a crutch, that’s when the real magic begins.

The food is just the beginning.

Healing comes when your life makes space for rest.

When I asked him what sparked joy — my now-standard question for new consults — he didn’t hesitate.

“Travel,” he said, his eyes lighting up. “Dozens of countries. I love learning how people live, eat, think.”

Then he paused. “But if I had to choose just one?”

He leaned forward, almost conspiratorially.

“Japan. Lived there over 25 years.”

I perked up. “Hontō ni?”

“Eh? Hontō hontō!” he beamed.

And just like that, the oncology suite turned into an izakaya.

We chatted in Japanese for several minutes — I, a Black man from the Pacific Northwest with a Japanese wife and a daughter who had attended college in Kyoto; he, a white man with a surprising Tokyo accent and stories that could have filled a dozen ryokans.

The nurses outside the curtain must’ve been baffled.

There we were: two middle-aged men, dressed like surgical extras, speaking rapid-fire Japanese about onsen, natto, and konbini snacks.

In radiation oncology, these are the moments you don’t forget.

The Kind of Joy You Can’t Buy

When our conversation drifted back to English, we kept circling the same theme: experience.

He told me about sleeping in the Sinai desert under a blanket of stars.

About sipping strong coffee in Addis Ababa.

About riding motorcycles through Southeast Asia before Google Maps existed.

What he didn’t talk about were things.

No fancy watches.

No new Teslas.

No gadgets.

Just the texture of moments lived.

And it hit me: the joy that lit up his face wasn’t the kind you get from opening a box.

It was the kind you earn by stepping into the unfamiliar. The kind that asks something of you — and gives back more than it takes.

The Science of Why It Feels So Good

We tend to think happiness is about comfort.

But psychologists like Dr. Laurie Santos (of Yale’s wildly popular Science of Well-Being class) suggest that the happiest people spend less on stuff and more on experiences.

Why?

Because of experiences:

• Give us stories we can retell
• Bring us into contact with others
• They are often tied to personal growth
• Don’t lose their sparkle the way objects do

A new phone gets old fast. But your first tuk-tuk ride in Bangkok? That stays with you.

There’s even a term for the trap we fall into with material things: hedonic adaptation.

The idea is that we quickly get used to new pleasures.

The house, the car, the clothes — they stop thrilling us.

But experiences?

They stay vivid.

I wrote about a similar theme in 10 Tiny Habits That Make You Healthier, Calmer, and Harder to Kill — the idea that intentional living creates lasting joy, not just fleeting dopamine hits.

My Favorite Journeys

Some of my favorite travel memories come from places that required a little more effort than, say, Paris or London.

• Egypt: navigating the frenetic, poetic chaos of Cairo traffic, then standing in stillness before the pyramids.
• Turkey: sipping tea in the shadow of the Blue Mosque, hearing the call to prayer echo across centuries.
• Japan: of course — always Japan — with its contradictions, its grace, its reverence for detail.
• Indonesia: maybe my favorite of all, where time moves differently and kindness is a national trait.

These places didn’t just offer a change of scenery. They offered a shift in me — the way I saw others, the way I understood culture, the way I experienced time.

What Travel (and Cancer) Teaches Us

My patient and I shared one more truth that day: that illness, like travel, strips you down to what matters.

It makes you see the world in a different light.

It humbles you.

And if you let it, it can open you.

Sometimes I think the best journeys aren’t measured in miles, but in mindset.

You don’t have to get on a plane.

You just have to notice something new.

Final Thoughts

That day in the exam room, two men with nothing in common on paper laughed like old friends, because we shared a language — and not just Japanese.

We shared curiosity.

And in that moment, amid machines and masks and schedules, we were both simply human.

In fact, isometric workouts are an excellent starting point for a healthier lifestyle because they require minimal resistance and can be performed at a lower intensity. As you become more self-assured, comfortable, and stronger, you can integrate more isotonic motions and weighted exercises, both of which are great ways to build strength and confidence. What are some ways isometrics can improve your body and mind?

1. Helps to preserve the strength of joints

Isometric exercises are more effective than traditional strength training in strengthening joints. Additionally, they can accomplish this without experiencing the discomfort commonly associated with other movements.

2. Causes a decrease in high blood pressure

An investigation conducted in 2023 showed that isometric workouts, particularly the wall squat, have the potential to be an efficient method for lowering blood pressure. By holding a squat position while leaning your back and shoulders on a wall behind you, you can do an isometric leg workout known as a wall squat (also known as a wall sit). The mechanism by which this affects blood pressure is not fully understood by researchers; however, they believe it may be related to the blood flow into and out of muscles when they contract and release.

In a study published in October 2023 in the British Journal of Sports Medicine, researchers combined the results of 270 clinical trials involving a total of over 15,000 participants. The effects of exercise on blood pressure were documented in each of the experiments, which lasted for a minimum of two weeks.

Exercising in various ways helped lower blood pressure, as expected. Isometric exercise training has been proven to be the most effective form of exercise, particularly for individuals with high blood pressure.

The pain associated with osteoarthritis can be excruciating, particularly when the joint is being moved through its full range of motion or when the patient is exercising. Individuals with osteoarthritis may benefit from engaging in isometric exercises to activate their muscles and maintain strength before adding additional resistance. This method is effective in reducing discomfort, increasing the range of motion, and enhancing function, according to research. How long should these muscles be held for the best results?

Beginners should hold for 3-10 seconds; experienced individuals, 30+ seconds. Cleveland Clinic Health Essentials suggests a gradual increase in exercise hold time, based on your body’s feedback and increasing strength.

Here are some isometric exercises. Remember to discuss this with your healthcare provider before any exercise, and begin slowly — do not attempt to proceed faster than your body can handle the exercise. Everyone will go at their own pace.

1. Phone calls and push-ups

You should position yourself so that you are arm’s length away from a wall and rest your palms flat against it at shoulder height. This should be done when you are standing and talking on the phone or waiting in line. Maintain this position while leaning forward slightly and engaging the muscles in your chest, shoulders, and core. This exercise helps ease stress and anxiety while also strengthening the upper body and improving posture.

2. Planks at the desk

By placing your hands on the edge of your desk and walking your feet back until your body forms a straight line, you may turn your desk into a useful tool for increasing your fitness level. This modified plank position should be held for thirty to sixty seconds.

In addition to preventing the detrimental consequences of sitting for extended periods, this workout targets the entire core, as well as the shoulders and arms. Besides removing mental fog and boosting attention throughout the workday, the concentration required to maintain good form serves as a form of mindfulness.

3. Commute glute squeezes

In any situation, whether you are sitting at your desk, in a car, or on public transportation, you can subtly clench your glute muscles and hold the contraction for ten to fifteen seconds before releasing it. As you perform this exercise, you will strengthen the largest muscle group in your body while also preventing the muscle weakness that can result from prolonged sitting. A meditative pattern can be created through the repetitive nature of squeeze-and-release, which helps reduce stress caused by commuting and promotes mental peace.

4. Calf Raises While Carrying Out Daily Tasks

Raise yourself up onto your toes and maintain the position for a few seconds before gradually lowering yourself back down when doing tasks like brushing your teeth, cooking, or doing the dishes. By strengthening the calves and improving circulation in the lower legs, this exercise is particularly beneficial for individuals who spend a significant amount of time sitting or standing for extended periods.

5. Abdominal Support During the Day

This invisible exercise involves gently drawing your navel toward your spine and maintaining that contraction while breathing normally throughout any activity you engage in. This is something you should practice while walking, sitting in meetings, or performing household or work duties.

A consistent abdominal bracing routine helps develop the deep core muscles, which in turn improve posture and support spinal health. In addition to enhancing bodily awareness, the conscious link between the mind and core muscles can also serve as a point of anchoring for maintaining presence and reducing stress throughout the day.

Isometrics are a great way to incorporate simple exercises into your daily routine, eliminating the need to go to the gym, use equipment, or take time out of your day. Each day includes exercise, allowing you to reap the benefits while going about your normal activities.
