The neuroscientist’s day,
hour by hour.

Sixteen to twenty-four ounces of water on an empty stomach, plus a greens drink (AG1) and an electrolyte mix (LMNT) for sodium, magnesium and potassium. The first job after a night of fluid loss is to restore the salts the nervous system runs on.

Non-Sleep Deep Rest — a guided body-scan practice that drops the system into a state close to sleep without actually sleeping. The function is dopaminergic: it replenishes the baseline that long days, screens and stress slowly drain.

Eyes toward the morning sky (not the sun directly) within an hour of waking. Low-angle photons through the retina trigger a cortisol pulse — the same one that, properly timed, becomes the evening melatonin rise sixteen hours later. If the sun is not yet up, a 10,000-lux lamp stands in.

A cold shower or ice bath in the 35–50°F range. Brief, repeatable, uncomfortable. The point is the adrenaline-and-dopamine spike that follows — a clean, drug-free chemistry for two to three hours of focused work.

A one-hour block following a fixed weekly split (see below). Training before the first meal exploits the fasted-state hormone profile; training at the same window each day removes the daily decision of whether to show up.

Coffee or yerba mate, deliberately delayed 90 to 120 minutes after waking. The delay lets adenosine — the molecule that built up overnight and signals tiredness — clear naturally. Front-loading caffeine before that clears almost always produces an afternoon crash.

Breaking the overnight fast around the 12–16 hour mark. Protein and vegetables dominate; carbohydrates are added only on heavy training days. Eating later, and lighter, keeps the morning's energy curve flat and the afternoon clear of food coma.

An optional afternoon repeat of the morning's deep-rest practice, used on light-sleep days. Twenty minutes here is treated as a partial substitute for an hour of missed nighttime sleep.

Optional easy movement — a walk, a slow jog, a hike. Intentionally low-intensity. A hard session this late would raise the core body temperature too close to bedtime and delay the evening melatonin rise.

Three to four hours before bed. Lighter than the first meal, with starches (rice, potatoes) introduced now rather than at lunch — the carbohydrate-driven serotonin pulse helps the wind-down. No refined sugar; nothing that will spike blood glucose during sleep.

Overhead lights off. Lamps low, ideally below eye level. No phones, no screens — and if there must be a screen, the warmest, dimmest setting available. The same retinal pathway that woke the body at sunrise will now suppress melatonin if exposed to bright light at this hour.

Cool room, dark room, fixed window. Sleep is the foundation underneath every other protocol on this list — the one variable that, if broken, breaks all the rest. Everything earlier in the day is, in some sense, a setup for this block.
