Almost everyone wakes between 1 and 3 a.m. because core body temperature starts rising again after dropping overnight, which moves you into lighter sleep, and what you do in the next few minutes decides whether you drift off or spiral.

• What to do: Skip the bathroom trip unless you truly need it (roll onto your back and count to 20 first), do not check the clock or phone, and start 4 7 8 breathing for 20 cycles.
• Why it matters: Falling asleep needs lower anxiety, temperature and heart rate. Standing up, doing clock math and forcing sleep raises all three, and a heart rate above about 60 makes unconsciousness hard.
• How to apply it: Breathe in for 4, hold for 7 and push out for 8, keeping the exhale longer than the hold. Track cycles by raising a finger each round. Build up with 4 5 6, then 4 6 7, over about a week. If you still cannot sleep, read a boring book in a set chair and return to bed when your eyes feel heavy.
• Metrics: Wake at the same time 7 days a week, because morning light sets melatonin to turn on roughly 14 hours later. Use the 3 2 1 rule: stop food and fluids 3 hours before bed, work 2 hours before, screens 1 hour before.
• Tools: LMNT electrolytes in the morning and an Oura ring to follow weekly trends, not nightly numbers. Counting backward from 300 by threes can also quiet a racing mind.
• Risks: Mouth taping can mask undiagnosed sleep apnea, especially after alcohol. Constantly checking trackers can cause orthosomnia, which is anxiety about sleep data.
• Exceptions: If you truly need to pee, go. If you feel electricity in your body like jet lag, that may be a body clock issue rather than a racing mind.

Nano fat injected under the eyes thickened thin skin and hid visible blood vessels within about four months, and it beat a CO2 laser and PRP because it rebuilds tissue quality instead of just filling a hollow.

• What to do: Name your main problem before buying anything: pigment, visible vessels, hollowness, temporary puffiness, a structural bag or thin crepey skin. Most people have more than one.
• Why it matters: Skin care can improve hydration, collagen support and pigment, but it cannot fill a tear trough or remove a fat pad. Asking a cream to do surgery work wastes hundreds or thousands of dollars.
• How to apply it: Use hydrating, brightening skin care around the eyes, keep filler very conservative, and consider a clinic procedure only when you keep thinking about the problem and the treatment matches its cause.
• Metrics: PRP and PRF needed repeat sessions every 3 to 4 months. The fat transfer took about 4.5 hours under local anesthesia, and roughly 50% of micro fat can be reabsorbed. Visible improvement appeared around month 3 and was clear at month 4.
• Tools: Major Fade Hyper Serum for hydration, antioxidants and brightening, plus Major Fade Active Seal for vitamin C, glutathione and peptides.
• Risks: Too much hyaluronic acid filler attracts water and looks puffy, heavy or more tired. Fat transfer is real surgery with soreness at the donor site, and it is not a yearly procedure.
• Exceptions: A true under eye bag or severe hollowness may need surgery, and Botox cannot replace lost volume.

Yes, you can be insulin resistant with normal blood sugar, because glucose is the last marker to rise while fasting insulin climbs first, and a fasting insulin under 5 is the target almost nobody tests.

• What to do: Ask for fasting insulin, hemoglobin A1C and fasting glucose, then check your waist to hip ratio and body composition instead of trusting glucose alone.
• Why it matters: One patient had glucose under 110 after two colas worth of sugar yet an insulin near 300, and doctors who test only glucose miss many cases.
• How to apply it: Cut starch and sugar, eat protein, fat and 30 grams of fiber, walk 10 to 20 minutes after meals, lift weights, sleep well and fast 12 to 14 hours overnight.
• Metrics: Fasting glucose 70 to 90, fasting insulin under 5, A1C about 5.0 to 5.2, post meal glucose under 110 to 120, waist to hip ratio under 0.8 for men and 0.9 for women.
• Tools: Function Health tests with an insulin resistance score from 0 to 100, a continuous glucose monitor for a few weeks and a tape measure.
• Risks: Statins, sleep apnea, chronic stress and artificial sweeteners can worsen insulin resistance or cravings.
• Exceptions: A glucose spike after eating is normal, and thin people can still carry hidden fat, so body composition matters more than weight.

You can keep doing hard things by switching between several drivers instead of relying on one, as ultra endurance swimmer Ross Edgley did over a 157 day swim around Great Britain, a 56 hour Yukon swim and 30 marathons in 30 days.

• What to do: Name your spokes before a hard task: because I said I would, fear of letting people down, love, anger, doing it for others, gratitude for what you can do and the absurd hero mindset.
• Why it matters: The anterior mid-cingulate cortex reportedly grows when you do hard things and shrinks when you avoid them, and one driver alone tends to fail during long, painful efforts.
• How to apply it: Focus on the next stroke or step instead of the clock, lower the stakes in your head when pressure builds, protect deep sleep and switch spokes when one fades.
• Metrics: Edgley swam almost 2,000 miles in about 157 days, 317 miles of the Yukon in 56 hours went 70 hours without sleep on the Yukon expedition and uses his pull-up one rep max as a strength reserve.
• Tools: Electrolytes, a glucose wearable, a temperature regulating mattress cover and a protein snack are mentioned as sponsor products, not as part of the model.
• Risks: Motives such as anger or ego can fuel you, but Edgley found records alone felt shallow and sleep loss can drain dopamine and serotonin.
• Exceptions: In ultra endurance an imperfect stroke is fine, while high stakes in precision tasks can overload the motor system and hurt performance.

Humans are far more olfactory than they admit: after a handshake people sniff their own hands, and invisible body odor can predict friendship, spread fear and cut men's free testosterone by about 14% within 20 to 30 minutes.

• What to do: Treat smell as a real social channel. Notice the hand-to-face sniffing that follows handshakes and give some weight to first impressions that "just click", because odor similarity predicted how friendly strangers rated each other.
• Why it matters: About 7 million receptors of roughly 350 types feed the olfactory bulb, which connects directly to the amygdala and hypothalamus, so odor can shift arousal, aggression and hormones without conscious awareness.
• How to apply it: Read "pheromone" claims with caution and use the term chemosignals instead. Remember that baby odor (hexadecanal) lowered aggression in men but raised it in women, so the same signal does not act the same way in everyone.
• Metrics: 14% drop in free testosterone after sniffing tears; 15 of 16 people identified digitized violets; a perceptual map of 4,000 molecules.
• Tools: Electronic nose with metal oxide sensors, the Taylor Aggression Paradigm and fMRI.
• Risks: Smell digitization is at the "1956 black and white TV" stage; rose and anise recreations failed, so do not expect products from it soon.
• Exceptions: Odor similarity predicted friendship ratings but not performance in the mirror game, and the tear effect was shown for men sniffing women's tears.

A registered dental hygienist names four 2026 favorites they use and recommend to patients: the Quip Rev oscillating toothbrush, GUM Professional Clean floss picks, Sensodyne Clinical Repair toothpaste and the Quip rechargeable cordless water flosser.

• What to do: Choose an affordable oscillating toothbrush, durable floss picks that do not fray and a sensitivity toothpaste with enamel remineralization, then add a water flosser if you want extra cleaning.
• Why it matters: Technique decides results. Guide an electric brush slowly from tooth to tooth and never scrub, and floss by hugging the tooth up and down on each side.
• How to apply it: Subscribe to brush head refills every 3 months, keep floss picks in your bag, car and desk, and start the water flosser on its gentle mode before moving to deep clean pressure.
• Tools: Quip Rev, GUM Professional Clean Floss Picks, Sensodyne Clinical Repair and the Quip water flosser.
• Risks: The Sensodyne version they use contains SLS, which can irritate some mouths. Check the label for an SLS-free option if you have irritation.
• Exceptions: Sensodyne costs more than some pastes, and the water flosser category is crowded, so compare options if budget matters.

Supplements work best as the third layer after behavior and nutrition, and the smartest move is to test one single ingredient formula at a time for about a week, because that is how you find the minimum effective dose and drop whatever does nothing for you.

• What to do: Answer three questions first: how well do you sleep, how good is your nutrition and what is your budget. With about $100 a month or more, start with a broad foundational formula (vitamins, minerals, digestive enzymes, probiotics, prebiotics, adaptogens).
• Why it matters: No supplement or drug can make up for poor sleep, light exposure, exercise and food for long. Ingredients also behave differently in different people, and the ideal dose for you may even be zero.
• How to apply it: For sleep, avoid caffeine after 2 p.m. and food in the last 2 hours. To fall asleep faster, try magnesium threonate or apigenin for one week each. For waking at night, consider 900 mg myo inositol. For focus, keep stimulants (caffeine) separate from neuromodulators (alpha GPC 300 to 600 mg, L tyrosine 500 to 1,000 mg).
• Metrics: Aim for more than 1 g of EPA a day from fish oil. Fadogia agrestis is around 600 mg a day, cycled 8 weeks on and 2 off, or 12 weeks on and 1 month off. Tongkat ali is around 200 to 600 mg a day, with blood work after 8 to 12 weeks. Protein is about 1 g per pound of body weight.
• Tools: Examine.com for ingredient forms, and a high quality omega 3 as the single most impactful supplement.
• Risks: Fadogia agrestis can be toxic to testicular cells at high doses, alpha yohimbine can cause strong anxiety, and melatonin doses are far above natural levels and may not keep you asleep.
• Exceptions: Skip theanine if intense dreams wake you at night. Women should expect some supplements to act differently across the menstrual cycle. Always check with a physician before changing any protocol.

Brain scans of people who were overweight or obese looked about 8 years older, and low estrogen, testosterone or thyroid hormone also sped up brain aging, so fixing metabolism, hormones and nutrition can visibly restore brain structure.

• What to do: Treat the brain through the body. Track cardiometabolic health, hormones and nutrients, and add a brain MRI with quantitative analysis plus Alzheimer's blood markers when family history or age 50 to 60 makes them relevant.
• Why it matters: Brain changes can show up about 30 years before Alzheimer's, and around 60% of people diagnosed with dementia have cardiometabolic problems. Scans show recovery after nutrition is restored, as in anorexia, where the brain improved most.
• How to apply it: Get a broad blood panel that includes vitamin D, iron, omega 3, heavy metals, insulin, thyroid, sex hormones, homocysteine and methylmalonic acid, then retest after changes to see your trend.
• Metrics: Alzheimer's incidence doubles every 5 years after age 70, from about 5% at 70 to 10% at 75 and 20% at 80. One APOE4 copy roughly triples risk, and two copies (about 6% of people) raise it 9 to 10 times. Key markers include p tau 217, amyloid beta 42/40, neurofilament light and GFAP.
• Tools: Functional MRI, PET, NeuroQuant brain age and brain charts, plus the Function Health panel. Sponsors named in the episode: Bon Charge red light mask, Paleovalley bars, Timeline Mitopure, Seed DS 01, BiOptimizers magnesium and Fatty15.
• Risks: A single marker or a normal structural MRI can miss the problem, because many psychiatric conditions show up in function, not structure. Imaging is more controversial than blood work.
• Exceptions: Only about 2% of Alzheimer's cases are directly genetic. APOE4 tilts risk but is not destiny, and its effect varies by ancestry.

Motivation does not arrive before action: the feeling follows it, so the fix is the 5 second rule, counting 5-4-3-2-1 and moving the instant you hit one, before your brain can talk you out of it.

• What to do: Answer "what do I want from now on?", pick one small action that a person with that life would take, and count backwards 5-4-3-2-1 to start it even if you do not feel like it.
• Why it matters: Hesitation lasts under 5 seconds before you talk yourself out of a choice, and a streak of 21 days is not a habit. The body keeps its capacity to change at any age, even for a person who has never lifted a weight.
• How to apply it: Put the phone and alarm across the room, lay out workout clothes, leave creatine and a protein shot on the counter, pre-pick the workout the night before and keep treats out of the house. Tie your goal to a personal reason, such as protected time for yourself.
• Metrics: Hyman went from 10 push-ups at 50 to about 75 push-ups and 15 pull-ups after starting to lift at 59; The Let Them Theory sold 11 million copies in 19 months.
• Tools: Function Health lab data, a pre-planned workout, an audiobook for walks, and the ABC model (apologize, back off, compliment) to influence others.
• Risks: Pressuring a loved one to lose weight or take medication triggers resistance. Talk to your doctor before starting hormone therapy or changing medication.
• Exceptions: For big decisions such as a contract or a marriage, stop and think. The 5 second rule is for everyday choices you already know are right.

An average American spends about 12.5 of their final years sick, disabled or in a nursing home, and this video blames chronic inflammation and chronic disease rather than age, which ten habits can push back.

• What to do: Pick one to three of the ten habits and start tonight: get labs, eat fat and animal protein first, cut sugar, grains and seed oils, lift something heavy two or three times a week and sleep at least 7 hours.
• Why it matters: Visceral fat is the most dangerous fat, and in a British Medical Journal study the weakest grip carried about one and two thirds the risk of death of the strongest grip.
• How to apply it: Measure your waist and height with a tape, take private photos every one to three months, fast 12 to 14 hours before blood tests, skip snacks, stand up and sit down every 10 to 15 minutes and raise the head of your bed.
• Metrics: Hemoglobin A1C, fasting insulin, triglycerides, HDL, hs-CRP, vitamin D 25, sex hormones, waist-to-height ratio, five timed floor rises and 10 seconds on each leg.
• Tools: A tailor's tape, light dumbbells, red bricks or 2 by 4 blocks under the bed legs and the Proper Human Diet community for accountability.
• Risks: Snacks of any kind, seed oils, alcohol and sugary breakfasts keep insulin and inflammation high.
• Exceptions: Some people do fine on 6.5 hours of sleep, and a first step can be as small as walking to the mailbox.
