Things I Actually Do for My Own Health (That Most People Don’t Know About)

I spend a lot of time telling patients what the research says. This post is a little different. These are the things I actually do for my own health, not because I read them on a wellness blog, but because the evidence supports them and they fit into real life. Most of them cost nothing or close to it. None of them are extreme. The goal, as always, is reducing harm and improving function over a lifetime, not achieving perfection.

I will note the evidence base for each one honestly. Some of these are very well established. Others are supported by smaller or emerging research. Where that is the case, I will say so.

A few of these tips will surprise you. Some might make you want to look up the research yourself, which I encourage. What I can tell you is that after nine years in family medicine and training in functional medicine, these are the habits I have actually built into my own life and recommend to the people I care for.

1. Cooking and Cooling Rice and Potatoes Before Eating Them

This is the one that surprises people most when I bring it up. The short version: freshly cooked white rice and potatoes digest quickly, spike blood sugar significantly, and do relatively little for your gut microbiome. The same rice or potatoes, cooked and then refrigerated for at least 12 hours, become a meaningfully different food.

Here is what happens chemically. When starchy foods are cooked, the starch granules swell and become highly digestible. When they cool, a process called retrogradation occurs: the starch molecules, particularly amylose chains, realign into tightly packed crystalline structures. These structures resist digestion by the enzymes in your small intestine. Instead of breaking down into glucose and entering the bloodstream rapidly, they pass largely intact into the large intestine. There, they are fermented by beneficial bacteria, which produce short-chain fatty acids, particularly butyrate. Butyrate is one of the most important compounds for colon health, gut lining integrity, and reducing intestinal inflammation. It is also emerging in research as having systemic anti-inflammatory effects.

The practical benefits are real and measurable. Multiple studies and meta-analyses show that resistant starch reduces postprandial (after-meal) blood sugar spikes and improves fasting blood sugar and insulin sensitivity over time. It feeds a healthier microbiome. It increases satiety through its effects on gut hormones like GLP-1, the same pathway that the popular weight loss medications work on. And for every additional day you refrigerate cooked rice or potatoes, the resistant starch content continues to increase for up to four days.

The part that surprises people most: you can reheat them. Resistant starch formed during cooling is largely heat-stable. Microwaving or warming on the stove does not undo most of what was built during the cooling period. What matters is that initial refrigeration, ideally at least overnight.

In practice, I cook a large batch of rice or potatoes once or twice a week, refrigerate them, and eat them over several days. When I want them warm, I reheat them normally. This requires no extra effort, no special ingredients, and costs nothing. It is one of the simplest evidence-backed nutrition habits there is.

2. Amla Powder in My Morning Smoothie

Amla, also called Indian gooseberry (Phyllanthus emblica), is a small, tart fruit that has been central to Ayurvedic medicine for thousands of years. It is now one of the most studied botanical compounds in nutritional science, and what the research shows is genuinely impressive.

In terms of raw antioxidant content, amla ranks among the highest of any food ever tested, surpassing blueberries, pomegranates, and acai by a wide margin in several comparative analyses. Its antioxidant activity comes from a unique combination of vitamin C, tannins, and polyphenols including gallic acid, ellagic acid, emblicanin A and B, and chlorogenic acid. What makes amla particularly valuable is that its antioxidant compounds are unusually stable compared to other vitamin C sources, meaning they survive processing, storage, and digestion better than most.

Clinical trials in humans have shown reductions in LDL cholesterol, total cholesterol, and triglycerides with amla supplementation. Studies have also shown improvements in fasting blood sugar and markers of insulin resistance, with one clinical study finding amla powder performed comparably to a common diabetes medication at lowering blood sugar, without the gastrointestinal side effects. Other research has documented reductions in inflammatory markers including hsCRP and improvements in endothelial function, which is relevant to cardiovascular health.

I add a teaspoon of amla powder to my smoothies most mornings. On its own it is intensely tart and not particularly pleasant. Blended with fruit, greens, and a liquid base, it essentially disappears into the flavor. It is inexpensive, easy to find online or in Indian grocery stores, and one of the highest-value additions you can make to a smoothie on a per-cost basis.

One important caveat: amla has meaningful blood-thinning and blood-sugar-lowering properties. If you are on anticoagulants, blood thinners, or diabetes medications, check with your provider before adding it regularly, as it can enhance the effect of those medications.

3. Gradually Weaning Off Sugar and Creamer in Coffee

This sounds almost too simple to mention, but the mechanism behind it and the long-term payoff are both worth understanding. Most people who try to cut sugar and creamer from their coffee or tea go cold turkey, find it unpleasant, and revert within a week. The problem is not willpower. It is neuroscience. Taste preferences are largely shaped by repeated exposure. When you consistently consume sweet beverages, your palate calibrates to expect sweetness, and without it the drink tastes flat or bitter. This calibration is real and measurable.

What is also real is that it can be reversed, slowly. I reduced the amount of sugar and creamer in my coffee by a very small amount every one to two weeks, so gradually that each individual change was barely perceptible. Over several months, the total reduction was dramatic. At no point did any single step feel like deprivation. Eventually the target changed, not because I forced myself to stop liking sweetness but because my palate had genuinely recalibrated. Black coffee now tastes rich and complex. Sweetened coffee tastes like dessert.

Why does this matter? The average American consumes somewhere between 17 and 20 teaspoons of added sugar per day. A significant portion of that comes from coffee drinks, flavored creamers, and sweetened teas, sources that are easy to overlook because they are beverages rather than food. Insulin resistance, metabolic syndrome, fatty liver disease, and type 2 diabetes are all driven in meaningful part by chronic excess sugar consumption. Reducing it does not require dramatic sacrifice if you approach it with patience and a long enough time horizon.

I now drink black coffee and unsweetened tea and genuinely enjoy both. That shift took several months and zero suffering. It is one of the lowest-effort, highest-impact dietary changes I have made.

4. Choosing Honey or Agave Over Refined White Sugar

When I do use a sweetener, I reach for raw honey or agave rather than refined white sugar. This is not because honey and agave are health foods in large quantities. They are not. But when sweetness is genuinely wanted, choosing the option with a better nutritional profile is a reasonable habit.

Raw honey is not simply sugar. It contains a diverse array of bioactive compounds: enzymes including glucose oxidase and catalase, antioxidant polyphenols, antimicrobial compounds, and trace minerals. It has a lower glycemic index than white sugar, meaning it raises blood sugar more slowly. Research has documented anti-inflammatory, antimicrobial, and prebiotic properties in raw honey that are not present in refined sugar. Importantly, these benefits are largely destroyed by pasteurization, so raw honey specifically is what matters here. The processed honey in most grocery store squeeze bottles has most of these properties eliminated.

Agave syrup has a notably low glycemic index due to its high fructose content, which is metabolized differently than glucose and does not cause the same rapid blood sugar spike. However, excess fructose has its own metabolic concerns, particularly for liver health, so agave is best used in genuinely small quantities. I use it primarily in cold beverages and smoothies where its liquid form blends easily.

The bottom line: if you are going to add a sweetener, add a better one. Just do not add more of it than you would have otherwise.

5. Morning Sunlight Within 30 Minutes of Waking

Light is the most powerful regulator of the human circadian clock, and most people in modern life are chronically underexposed to it in the morning and overexposed to artificial light in the evening. The consequences for sleep quality, cortisol rhythm, melatonin production, mood, and metabolic health are significant and well-documented.

The mechanism: natural light exposure in the morning activates specialized cells in the retina (intrinsically photosensitive retinal ganglion cells) that connect directly to the suprachiasmatic nucleus, the brain’s master circadian clock, located in the hypothalamus. This signal sets the entire daily rhythm of hormone secretion, body temperature, and alertness. Specifically, morning light exposure triggers a healthy cortisol awakening response, a natural spike in cortisol that promotes alertness, focus, and energy during the morning hours. It also sets the countdown for melatonin, which rises naturally 12 to 14 hours after morning light exposure. People who get adequate morning light fall asleep more easily, sleep more deeply, and wake more alert.

Research published in peer-reviewed journals confirms that morning light exposure improves sleep duration, sleep efficiency, mood, and daytime alertness. Even on cloudy days, outdoor ambient light is 10 to 50 times brighter than typical indoor lighting, which means that going outside, even briefly, provides a circadian signal that sitting near a window cannot fully replicate.

What I actually do: I step outside within 30 minutes of waking, without sunglasses, for 5 to 10 minutes. On bright days, 5 minutes is enough. On overcast days, I aim for closer to 20. I do not look directly at the sun. I do not look at my phone. I stand or walk outside and let the light reach my eyes from the ambient sky. It costs nothing and the evidence behind it is among the most robust in behavioral sleep science.

6. Ending My Shower Cold

Every morning I finish my shower with 30 to 60 seconds of cold water. I am not going to pretend this is pleasant, especially at first. It is not. But it becomes dramatically easier within two to three weeks, to the point where it feels like something is missing on the rare day I skip it.

The evidence base for cold water exposure has grown substantially in recent years. A 2025 systematic review and meta-analysis published in PLOS ONE, one of the most rigorous assessments of the evidence to date, found that cold water immersion reduces inflammation, reduces stress markers, improves sleep quality, and supports overall wellbeing. A randomized controlled trial found that people who took regular cold showers had a 29% reduction in sick days compared to those who did not. Multiple studies document a rapid and significant release of norepinephrine, a neurotransmitter that improves mood, focus, and energy, following cold exposure.

Cold exposure also activates brown adipose tissue, a metabolically active type of fat that burns calories to generate heat and is associated with improved insulin sensitivity and metabolic health. This is distinct from regular white fat, which stores energy. Cold exposure is one of the most reliable ways to activate brown fat in adults.

The honest caveat: most of the research is on cold water immersion at temperatures below 15°C for at least 30 seconds, which is colder than most showers get. The evidence for cold showers specifically, as opposed to ice baths, is somewhat less robust, though mechanistically plausible and biologically consistent with the immersion research. For healthy people, the risk is essentially zero and the potential upside is meaningful. I consider this one of the better effort-to-benefit ratios in my daily routine.

If you want to try this, do not start with cold only. Start with your normal warm shower and turn it cold for the last 15 to 30 seconds. Gradually increase the duration over a few weeks. Breathing through the initial cold shock rather than gasping makes it significantly more manageable.

7. Walking Barefoot on Natural Surfaces

Grounding, or earthing, is the practice of making direct skin contact with the earth’s surface. Grass, soil, sand, and natural stone all conduct electrons. The earth maintains a natural negative electrical charge, and the proposed mechanism of grounding is that when bare skin contacts the earth’s surface, electrons transfer from the ground into the body, where they may act as natural antioxidants, neutralizing positively charged free radicals involved in oxidative stress and inflammation.

I want to be transparent about where the evidence stands here. The research on grounding is real but mostly consists of small studies rather than large randomized controlled trials, and some studies have methodological limitations. That said, the findings are consistently interesting. Studies have found reductions in markers of inflammation including cortisol and white blood cell activity, reductions in muscle soreness after exercise, improvements in sleep quality, and reductions in subjective pain after regular grounding sessions. A review published in the Journal of Inflammation Research documented that grounded participants showed significantly less muscle damage and inflammatory markers after exercise compared to ungrounded controls. Research published in Integrative Medicine has argued that grounding should be considered as a foundational recommendation in lifestyle medicine.

I walk barefoot in the grass several times a week, usually in the morning when I am already outside for sunlight exposure. There is no downside, no cost, and no required equipment. Even if the electron-transfer mechanism is not the whole story, the psychological and neurological benefits of spending time outdoors in contact with natural surfaces are well-established through the broader literature on nature exposure and stress reduction.

8. Reducing Chemical Exposure at Home

This is the topic I find myself talking about most in practice, and the one that gets the most pushback because it requires questioning things we have used our entire lives without thinking twice. The core principle is this: the liver is designed to process and eliminate toxins from the body, and it does this remarkably well. But it operates within a threshold. When the body faces a continuous, daily stream of chemical inputs from multiple sources simultaneously, the cumulative burden over years can exceed the liver’s clearing capacity. The result is not acute poisoning. It is a slow accumulation of harm that shows up decades later as hormonal dysregulation, neurological changes, immune dysfunction, and increased cancer risk.

The sources of this burden are everywhere in a conventional household. Pesticide residues on conventionally grown produce. Glyphosate in wheat products (from preharvest desiccation practices, where it is sprayed directly on the crop before harvest). Synthetic fragrances in laundry detergent, dryer sheets, air fresheners, cleaning products, and personal care products. Phthalates and other plasticizers in food packaging and synthetic fabrics. Off-gassing from synthetic carpets and furniture. Each of these, individually, involves what regulators consider an acceptable level of exposure. The problem is that we are exposed to dozens of them simultaneously, every day, for our entire lives. The combined, cumulative load is what produces harm, not any single exposure.

Here is what I actually do, in order of impact:

Air fresheners: I do not use them. They are among the worst offenders for volatile organic compound (VOC) exposure, synthetic fragrance chemicals, and endocrine-disrupting phthalates. I use a diffuser with essential oils when I want scent in my home.

Cleaning products: I make my own. An all-purpose cleaner is white vinegar diluted with water and a few drops of tea tree or lavender oil. Glass cleaner is the same, sometimes with a small amount of rubbing alcohol. Bug spray can be made with witch hazel, water, and a combination of essential oils including lemon eucalyptus, rosemary, cedarwood, and peppermint. These work, they cost a fraction of commercial products, and they are not toxic. The argument that you need commercial products for effective cleaning is largely a marketing claim.

Laundry: Fragrance-free detergent and no dryer sheets. Dryer sheets coat fabrics with a layer of synthetic fragrance and softening chemicals that then sit against your skin for hours. Wool dryer balls are an effective alternative for static reduction.

Clothing and fabrics next to skin: I have switched to organic cotton underwear. The fabric that is in contact with your skin and mucous membranes for the most hours of every day is a reasonable place to reduce pesticide and synthetic dye exposure. Conventional cotton is one of the most pesticide-intensive crops in agriculture. Organic cotton is not dramatically more expensive for basic items like underwear and is widely available.

Produce: I choose organic when buying the produce with the highest pesticide residues, which the Environmental Working Group publishes annually as the Dirty Dozen. I do not stress about organic for everything, because not all produce carries the same pesticide burden and the incremental cost adds up quickly.

The goal is not elimination. It is reduction. The body is well-equipped to handle modest chemical exposure. What it is not well-equipped to handle is an unrelenting daily onslaught from dozens of synthetic compounds simultaneously for 60 or 70 years. Shifting even 30 to 40% of your exposures reduces the cumulative burden meaningfully over time.

9. Choosing Pasture-Raised and Grass-Fed Animal Products

When I buy eggs, beef, or pork, I choose pasture-raised and grass-fed specifically, not just because of how the animals are treated (though that matters too), but because the nutritional content of what they produce is measurably different from their conventionally raised counterparts.

Pasture-raised eggs, from hens that spend time outdoors eating grass, insects, and a varied diet rather than living in cages on grain, have been shown in multiple studies to contain significantly higher levels of omega-3 fatty acids, vitamin D, vitamin E, and beta-carotene compared to conventional eggs. One study found pasture-raised eggs contained up to twice the omega-3s and 38% more vitamin E than conventional eggs. Omega-3s are anti-inflammatory and critical for brain, cardiovascular, and hormonal health. The conventional egg you buy in most grocery stores has a dramatically less favorable nutritional profile, not because eggs are bad but because of how those animals were raised.

The same principle applies to beef. Grass-fed, pasture-raised beef has a substantially better omega-3 to omega-6 ratio than grain-finished beef. It also contains higher levels of conjugated linoleic acid (CLA), a fatty acid with documented anti-inflammatory and potentially anti-cancer properties, as well as higher levels of vitamins A, E, and K2. Grain finishing, which is standard practice in conventional beef production, dramatically shifts the fatty acid profile of the meat toward inflammatory omega-6s.

These distinctions are not marketing. They are documented in peer-reviewed nutritional research. If you are going to eat animal products, choosing quality sources gives you a meaningfully better nutritional return for the same caloric investment.

10. Shopping at the Farmers Market Whenever Possible

Nutrient density in fruits and vegetables begins declining the moment they are harvested. This is not a metaphor. It is biochemistry. Enzymes activated at harvest begin breaking down vitamins and antioxidants immediately. The speed of this decline depends on the produce type, storage conditions, and how much time passes between harvest and consumption.

Conventional supermarket produce in the United States typically travels an average of 1,500 miles from farm to shelf. Domestic produce may take five to seven days from harvest to reach a store shelf. Imported produce may be in transit for weeks. Then add the days it sits in the store and the days in your refrigerator before you eat it. By that point, particularly for fragile nutrients like vitamin C, folate, and many antioxidant compounds, meaningful degradation has occurred.

Research comparing locally grown to conventionally shipped produce has found that vitamins and antioxidants can be more than 100% higher in local crops. Farmers market produce is typically harvested 24 to 48 hours before sale, meaning it reaches you at or near peak nutritional density. For some items, particularly leafy greens, berries, and tomatoes, this difference is substantial.

Beyond the nutrition argument, buying from local farmers supports independent agriculture, keeps money in the local economy, reduces the environmental cost of long-distance food transport, and often gets you access to heritage and heirloom varieties that are more nutritionally dense than the commercial varieties bred for durability during shipping. I buy eggs, seasonal produce, and meat from local farms at the market whenever I can. I can ask the farmer directly about their practices, which is not something you can do at a grocery store.

11. Mineral Sunscreen Over Chemical Sunscreen

The FDA currently classifies only two sunscreen active ingredients as Generally Recognized as Safe and Effective (GRASE): zinc oxide and titanium dioxide. These are the minerals in mineral sunscreen. Every other active sunscreen ingredient, including oxybenzone, avobenzone, octinoxate, octocrylene, and others found in most conventional chemical sunscreens, is classified as needing further safety data before it can receive that designation.

This matters for a specific reason. A 2019 study published in JAMA demonstrated that oxybenzone, after a single day of application following standard sunscreen use instructions, produced plasma concentrations of 94.2 ng/mL in human subjects. The FDA’s threshold for systemic absorption requiring additional safety testing is 0.5 ng/mL. Oxybenzone exceeded that threshold by nearly 200-fold after a single day of use. A 2023 review of 254 studies found mounting evidence that oxybenzone has endocrine-disrupting properties at concentrations typical of regular sunscreen use, with potential effects on reproductive hormones.

I want to be clear about what this does and does not mean. It does not mean that chemical sunscreen definitively causes harm in humans, or that you should stop wearing sunscreen. Skin cancer is real and UV protection is important. What it means is that when a safer alternative exists that provides equivalent UV protection, it makes sense to use it. Zinc oxide blocks both UVA and UVB radiation, does not absorb into the bloodstream in meaningful amounts, and is the ingredient recommended by the American Academy of Pediatrics for children and by most hormone-aware practitioners for anyone with endocrine health concerns. The white cast of older mineral formulations has improved significantly in recent years, and many newer mineral sunscreens blend in without leaving a visible residue.

I use mineral sunscreen when sun protection is warranted. For everyday low-intensity UV exposure, I prefer getting natural sunlight without sunscreen, particularly in the morning hours when UV index is low and the vitamin D synthesis benefit is real. Blocking all UV exposure is its own problem given how common vitamin D deficiency is.

12. Keeping My Phone Away From My Body

I do not sleep with my phone beside my bed. I use a traditional alarm clock. When I am not using my phone, I do not carry it in my front pants pocket or keep it pressed against my skin. I have installed a wifi kill switch so the router turns off at night. I have reduced the number of smart devices in my home and avoid having them in my bedroom.

I want to be upfront about the evidence here because I think honesty matters more than certainty. The research on radiofrequency electromagnetic field (RF-EMF) exposure from phones is genuinely mixed and the science is still developing. There is no established causal proof that typical phone use at the population level causes specific diseases in humans. What there is: plausible biological mechanisms for harm at the cellular level, some epidemiological signals in heavy users, recommendations from the International Agency for Research on Cancer (IARC) classifying RF-EMF as a possible human carcinogen (Group 2B), and a clear absence of any benefit from having the phone physically against your body while you sleep.

My approach is the precautionary principle. When an exposure has plausible biological risk, no compensating benefit, and is trivially easy to reduce, reducing it is rational regardless of whether the harm is definitively proven. Keeping your phone in another room at night costs you nothing. Neither does not carrying it in your front pocket. The wifi router being off overnight costs you nothing. These are minimal-effort changes that reduce a potentially meaningful exposure during the hours when your body is most focused on repair.

This is not fear. It is proportionate risk management applied consistently, the same way I wear a seatbelt not because I expect to crash but because the cost of wearing one is zero and the downside of not wearing it is significant.

13. Cast Iron and Stainless Steel Cookware

I do not own nonstick cookware. Everything in my kitchen is cast iron or stainless steel.

PTFE, the compound used to create nonstick coatings, begins to break down and release toxic compounds at temperatures above 500°F. A dry pan on a medium-high burner can reach that temperature in minutes. The breakdown products include toxic gases that are lethal to pet birds (a fact that has been documented for decades) and cause flu-like symptoms in humans at higher concentrations. Beyond acute toxicity, PTFE is part of the broader PFAS (per- and polyfluoroalkyl substances) chemical family, known as forever chemicals because they do not break down in the environment or in the human body. PFAS chemicals are now found in the blood of virtually all Americans and are associated with hormonal disruption, immune dysfunction, thyroid disease, and certain cancers.

Nonstick coatings also physically degrade over time, and those coating particles end up in food. There is no safe amount of PFAS consumption, and eating food cooked in a scratched nonstick pan is a direct route of ingestion.

Cast iron is one of the oldest and most reliable cooking surfaces there is. A well-seasoned cast iron skillet has a naturally nonstick surface that rivals Teflon for most cooking tasks. It adds a small but meaningful amount of dietary iron to food, which is beneficial for many people, particularly menstruating women. It lasts indefinitely, handles extreme heat without issue, can go from stovetop to oven, and costs roughly the same as a mid-range nonstick pan. Stainless steel is similarly durable, easy to maintain, and safe at all cooking temperatures.

If you currently own nonstick cookware, I am not suggesting you throw it all away today. But I would replace it with cast iron or stainless steel as pieces wear out, and I would stop using any nonstick pan that is scratched or visibly degrading.

14. Blue Light Blocking Glasses After Dark

The mechanism here is well-established and not seriously disputed: blue light wavelengths, in the range of 450 to 490 nanometers, suppress melatonin secretion by the pineal gland. This is the same wavelength that natural sunlight is richest in during midday, which is part of why your brain interprets it as a signal of daytime alertness. In the evening, when you are looking at a phone, laptop, or television screen, you are flooding your retina with blue wavelengths at a time when your brain should be ramping up melatonin production in preparation for sleep. The result is delayed melatonin onset, later sleep timing, reduced total sleep time, and worse sleep quality.

Blue light blocking glasses, specifically amber-tinted lenses that filter a meaningful proportion of blue wavelengths, are proposed as a way to mitigate this effect. The evidence is real but mixed. A 2025 systematic review and meta-analysis found that blue light blocking glasses improved sleep onset latency and overall sleep efficiency, but the effect sizes were modest and studies were heterogeneous. A separate 2025 study in schoolchildren found that wearing the glasses advanced sleep timing and improved morning mood despite not measurably changing melatonin secretion, which suggests benefits may operate through mechanisms beyond melatonin alone.

What I do: I wear blue light blocking glasses starting about two hours before my intended sleep time when I am using screens in the evening. I also dim my screens, use night mode on devices that offer it, and try to reduce screen time in the last hour before bed. The combination feels more effective than any single intervention alone. My sleep onset is noticeably faster on evenings I am consistent with this than on evenings I am not.

The underlying biology is solid even where the specific effectiveness of the glasses is debated. If you are going to use screens in the evening, which most of us are, reducing blue light is a reasonable and low-cost intervention.

15. Time in Nature, Specifically Outside and Without a Phone

The final habit is the broadest and in some ways the most evidence-backed of all. Spending time in natural environments, particularly green spaces, has documented and substantial effects on cortisol levels, blood pressure, heart rate variability, immune function, and mood. The Japanese practice of shinrin-yoku, translated as forest bathing, involves slow, mindful time in a natural setting without exercise as a goal, simply being present in a natural environment. It has been studied extensively, and the findings are consistent: even 20 to 30 minutes in a natural setting reduces cortisol, lowers blood pressure, improves heart rate variability as a measure of nervous system regulation, and increases natural killer cell activity in the immune system.

The mechanisms are multiple and probably additive: phytoncides (antimicrobial compounds released by trees) inhaled during forest exposure have documented immune effects. Reduced noise pollution lowers stress hormone production. Visual complexity of natural environments engages the default mode network of the brain in a way that promotes cognitive restoration. And if you are barefoot, grounding adds its own potential benefit.

What I actually do is combine several of these: morning sunlight exposure, barefoot contact with natural ground, and time away from screens and devices, all at once. Even 15 to 20 minutes outside in the morning, barefoot in the grass with no phone, accomplishes all three simultaneously. The nervous system benefit I notice from this habit is real and consistent.

We evolved spending essentially all of our time outdoors in contact with the natural world. The complete divorce from nature that modern life produces is historically unprecedented, and the chronic stress, immune dysregulation, and sleep disorders that characterize modern health are at least partly a consequence of it. Getting outside is not a wellness trend. It is returning to a baseline that our biology expects.
