Behaviors

If you wake briefly at night, use the bathroom, and can fall back asleep, that is probably not a problem.

Following consistent timing for light, food, and exercise may help people experience healthier seasonal adaptation.

If you want a 10-hour real-world feeding window, select 8-9 hours; if you want 8 hours, aim for 6-7 hours, because most people underestimate their actual eating window and tend to eat outside it.

Avoid 4-6 hour feeding windows for most people, as they tend to promote overeating and may not improve weight outcomes. In practice, do not go much below 8 hours if training hard, under high life stress, or trying to maintain ovulation/fertility, due to hormone and stress considerations.

Once a comfortable feeding window is established, maintain it for at least 30 days; ideally indefinitely.

High-intensity interval training later in the day can lower blood glucose and help accelerate the transition into a fasted state before sleep, provided you do not eat afterward and do not use caffeine or anything else that disrupts sleep.

For people whose hormone health does not do well with time-restricted feeding, eating more meals spread throughout the day, presumably smaller meals with the same caloric intake, may be more beneficial.

Use the sauna three or four times per week, about 1-2 hours before sleep.

Place specific habitual routines at particular intervals throughout the day to leverage dopamine and divide the day into functional units. Have one specific dopamine-evoking habit after waking, insert another regular habit around breakfast or later in the morning, and keep the sequencing regular without being obsessively precise about exact timing. Example given: habit markers around 8 a.m. and 10 a.m. to define distinct epochs within the morning.

To relieve ear pressure during altitude changes, open the passageway behind the eardrum by plugging the nose and blowing out, plugging the nose and sucking in, or moving the jaw; the key is opening the passageway so the pressure differential can resolve.

One optional way to increase autonomic arousal before gratitude work is cyclic hyperventilation: very deep inhale-exhale breathing for 25 to 30 breaths, followed by meditation or writing gratitude notes.

Write down the things you are grateful for and then spend a moment thinking about or feeling into them. This common gratitude practice may be slightly more effective if preceded by increased autonomic arousal.

Center the practice on receiving genuine, wholehearted thanks rather than only expressing gratitude, because receiving gratitude appears especially potent for activating gratitude-related prefrontal circuits. A useful version is to recall a time when someone sincerely thanked you and focus on how it felt.

After choosing your gratitude story, write 3 or 4 short bullet points on a small sheet of paper or in your phone to cue the practice later. Include the struggle or pre-gratitude state, the help or gratitude event, the post-gratitude state, and any emotionally salient elements or how it impacts you emotionally. Read these bullet points as a cue to your nervous system before feeling into the experience.

Calming breathing can be done before a gratitude practice, but it is optional and not required. Examples include exhale-emphasized breathing or physiological sighs to help slow the heart rate and calm down beforehand.

Time eating and supplements strategically so muscle can be built at certain times without constant growth signaling.

Do not take certain supplements continuously; instead use every-other-day dosing or periodic breaks to give the body rest.

Measure biological age to assess whether interventions are working.

Opt out of airport scanners that use radiation and choose alternative screening such as the metal detector.

Try to minimize dental X-rays because radiation exposure is cumulative.

Do not rely on the withdrawal method to avoid unwanted pregnancy; it was described as a poor contraceptive choice.

Move the eyes from side to side with eyes open; described as reducing activation of the amygdala/threat reflex circuitry and lowering sympathetic arousal.

Maintain regular, trusting social connection while working through fear or trauma, such as conversing, sharing a meal, or appropriate physical touch. This can be beneficial whether in therapy or working alone and may reduce tachykinin-related amplification of fear and trauma.

Assess whether internal sensations are reasonable given external circumstances; he presents this as a biological component people can assess for themselves when considering fear/trauma.

Very brief daily deliberate stress exposure, potentially for 2 weeks, is presented as a promising protocol for recalibrating stress/fear systems. He emphasizes self-directed entry into the stressed state and cautions that longer bouts like 15 minutes/day may worsen trauma/fear. Methods can include deliberate cold exposure such as a cold shower, ice bath, or cold water immersion.

View healthy foods as potent for energy, immune function, and endocrine function, and approach eating them with a mindset of indulgence, satisfaction, and enjoyment rather than chronic restraint or deprivation.

View exercise as remarkably potent and effective for health, and cultivate a sense of enoughness rather than constantly feeling you never get enough exercise.

If numerical sleep or recovery scores cause negative expectancy effects, avoid looking at device readouts and instead decide subjectively on waking whether you slept well or not.

If working in the middle of the night, keep light only as bright as needed to do the work in order to avoid suppressing melatonin and shifting circadian rhythm. If you must stay awake all night and are struggling to remain awake, turn on as many bright lights as possible despite the circadian tradeoff.

After drinking water during an all-nighter, avoid going to the bathroom for at least 90 minutes to leverage bladder-driven alertness; example given was 32 ounces of water.
