iv. The protocols · every day
The daily protocols.
Five things a man does every day of the year, in a village, with no money and nothing to buy: light, sleep, rest, movement and, four days at a time, writing. The card format is borrowed from Huberman Lab's toolkits (2021–2026), with one difference: I grade the evidence; he does not.
The most ordered day I know of belonged to a thirteenth-century friar. Thomas Aquinas began with two masses, one he said and one he attended, then read, taught and wrote almost without a break, dictating to as many as three secretaries at once, with a short sleep in the middle of the day; fifty folio volumes in twenty-five years. Genius, yes — and, in Bishop Barron's phrase, a man of "extraordinary order and discipline." The cards below are smaller than that, on purpose.
Andrew Huberman, a Stanford neuroscientist, made the format popular: a timing, a dose, a fallback and a one-line reason for each step. His written protocols carry no evidence grade, no sample sizes and no species. So each card here adds a grade, and names the study behind it in a line — including when the study turns out to be eight meditation teachers in a brain scanner.
TestedMany studies, pooled in reviews or guidelines, support it, and the size of the effect is known.
PromisingA few small or narrow studies support it. Not proven.
PremiseA plausible mechanism. No study has tested it as an outcome.

- iiSleepthe last hour of the day · every night Promising
- iiiRest (NSDR)10–20 min · after a bad night or after learning Promising· Premise

During the silence, the temple's rules come first. Where a card and the abbot disagree, follow the abbot.
Nothing on these cards is medical advice, and nothing on them costs money. Every study is listed in full under the seasons.
Card i · Every morning
Morning light
- Time
- 5–20 minutes
- Needs
- The outdoors
- When
- Within an hour of waking
- Evidence
- Promising
Steps
- Within 60 minGo outside. A window does not count. Face the bright part of the sky; never look straight at the sun.
- 5–10 minOn a clear morning. Walk, sweep the yard, stand at the gate. No sunglasses; ordinary glasses are fine.
- 20 minWhen it is overcast. Huberman's own figure for a cloudy morning drifts between his documents, from 15 to 60 minutes; this card says 20.
Why
Bright light in the early morning raises cortisol, compared with dim light: the conclusion of a 2023 review of twelve studies (Robertson-Dixon et al.).
PromisingEvidence
The study Huberman lists for this, Petrowski et al. (2019), was 23 healthy men in a sleep laboratory: men only. The 2023 review counted 337 people across its twelve studies, 264 of them men, and most of the studies were not adequately blinded. The rise in cortisol is what the review found. The further claims — that the light sets a timer for sleep 14–16 hours later, and the benefits said to follow from that — are mechanism, not tested outcomes.
If you can't…
- …go out because it is still dark: turn on the brightest light indoors, then go out when the sun is up.
- …go out at all, ill or in the silence: sit in an open doorway facing the sky.
- …spare ten minutes: take two. Walk to school the long way tomorrow.
Stop if…
- the light hurts your eyes. Look lower; never at the sun. If you have an eye condition, ask a doctor first.

Card ii · Every night
Sleep
- Time
- The last hour of the day
- Needs
- A cloth for the window
- When
- Every night, every morning
- Evidence
- Promising
Steps
- On wakingGet up at the same time, within half an hour, seven days a week — after a bad night too.
- By noonYour last coffee, tea, cola or energy drink. Huberman's rule is none within 8–10 hours of bed.
- Last hourPhone off and out of reach, in another room if you can. A printed book, a conversation, the journal.
- Lights outA dark room: a cloth over the window, the lights off, nothing glowing.
Why
Caffeine taken six hours before bed still cut measured sleep by more than an hour (Drake et al. 2013).
PromisingEvidence
Small laboratory studies. Drake et al. (2013): 12 healthy sleepers and 400 mg of caffeine, about two to three cups of coffee, with sleep measured by a monitor at home. Chang et al. (2015): 12 young adults read on a lit screen for four hours before bed, five nights running, against a printed book; their evening melatonin fell by about half, they took about ten minutes longer to fall asleep, and they were sleepier the next morning. I have found no trial of these four steps as a package.
If you can't…
- …keep the wake time after a vigil: keep it anyway, and take card iii at midday.
- …stop coffee by noon: move it an hour earlier each week.
- …be without the phone, because family may call: leave it face down across the room, screen dark.
Stop if…
- you still lie awake most nights after four weeks of this, or you nod off while teaching or riding a motorbike. That is for a doctor, not a stricter card.

Card iii · When it is needed
Rest (NSDR)
- Time
- 10–20 minutes
- Needs
- A floor and a mat
- When
- After a bad night, or straight after learning
- Evidence
- Promising(rest after learning) · Premise(the rest)
Huberman calls it NSDR, non-sleep deep rest; the older name is yoga nidra. The script below is free and needs nothing.
Steps
- 0–2 minLie on your back, arms by your sides, eyes closed. Breathe in through the nose; breathe out slowly, about twice as long.
- 2–12 minMove your attention slowly up the body: feet, calves, knees, thighs, hips, belly, chest, hands, arms, shoulders, neck, face. Name each part silently and let it go heavy. Do not move it.
- 12–18 minLet the breath be ordinary. When you notice you are thinking, go back to the feet.
- Last 2 minOpen your eyes, roll onto one side, sit up slowly.
If a phone is allowed, Huberman Lab's free 10- and 20-minute recordings (hubermanlab.com/nsdr) are the same idea, spoken.
Why
Ten minutes of quiet, eyes-closed rest straight after learning helped people remember more of a story a week later than ten minutes of a spot-the-difference game (Dewar et al. 2012).
Promising· Premise· Evidence
Promising for rest after learning: one laboratory study, and of plain quiet rest, not a script. Premise for the rest. The popular reason, that NSDR raises brain dopamine "by as much as 65%", comes from Kjaer et al. (2002): eight expert meditation teachers, one brain scan each, and no outcome measured. I have found no study showing that it makes up for a lost night.
If you can't…
- …lie down: sit against a wall and do the same.
- …stay awake: then you needed sleep. Keep it to 20 minutes.
- …find ten minutes: do step one for two.
Stop if…
- lying still with your eyes closed brings back something you cannot hold. Open your eyes, sit up, and tell someone.

Card iv · Every day
Movement
- Time
- 30 min a day; 60–90 on Sunday
- Needs
- A floor, a sturdy table or a low branch
- When
- Every day, in a weekly pattern
- Evidence
- Tested· the amounts
Steps
- Daily · 30 minWalk briskly. To school and back counts. In the heat, go early or late.
- Mon, Wed, Fri · 25 minThree rounds, two minutes' rest between. Push: push-ups. Pull: lie under a sturdy table, grip the edge and pull your chest up to it, or do the same from a low branch. Legs: squats, then lunges or step-ups on the temple stairs. End each set with two good repetitions still in you.
- Sunday · 60–90 minOne long walk: the field roads to the next village and back.
Why
The World Health Organization recommends 150–300 minutes of moderate activity a week plus strength work on two or more days, and lists lower death rates, better sleep and fewer symptoms of anxiety and depression among the benefits (Bull et al. 2020).
TestedEvidence
Tested for the amounts: they are WHO's 2020 guidelines, built on systematic reviews of outcome studies. This week, about four hours of walking and three strength sessions, meets them. The split itself is mine, and untested.
If you can't…
- …do a push-up: push against a wall or a table edge, and step your feet back as you get stronger.
- …walk in the heat: walk in the first hour after waking. It doubles as card i.
- …manage three rounds: do one. Next week, two.
Stop if…
- you feel chest pain or pressure, faintness, or breathlessness out of proportion to the effort. Stop, sit, and see a doctor before you go again.
- in the heat, you get a headache, confusion, or stop sweating. Get into shade and drink water.

Card v · Four days, now and then
Expressive writing
- Time
- 15–20 min, four times
- Needs
- Paper and a pen
- When
- Four days running, or once a week for four weeks
- Evidence
- Tested· small effects
Steps
- BeforeFind a place where no one will interrupt you. These pages are not the journal; you may tear them up afterward.
- 15–20 minWrite without stopping about the most upsetting experience of your life: what happened, what you felt then and feel now, and how it connects to the rest of your life — your parents, your work, who you are. Ignore spelling. If you run dry, repeat yourself.
- Days 2–4The same again. Stay with the same event or go to another.
- After · 10 minSit for a while before you go back to people. Expect to feel worse for a time.
Why
Students who wrote about a trauma for 15 minutes on four days made fewer visits to the health center in the months that followed than students who wrote about neutral topics (Pennebaker & Beall 1986).
TestedEvidence
Tested, with modest effects. Pooled studies put the effect at d ≈ 0.47 across 13 studies of healthy people, and d ≈ 0.19 for physical health across 9 studies of clinical groups: real, small, and smaller for people who are already unwell (Baikie & Wilhelm 2005). The same review says the usual immediate effect is a short-term rise in distress.
If you can't…
- …manage four days in a row: once a week for four weeks.
- …face the worst thing yet: write about a hard thing you can face.
- …write during the silence: the abbot decides. It can wait.
Stop if…
- the distress is still with you days later, or the writing brings back something you cannot hold. Stop, and talk to a person; in Thailand call 1323. This does not replace a doctor or a therapist.
