Every sauna and heat protocol
21 protocols, pulled from 222 clips across 93 episodes of Huberman Lab. He puts the dose at 57 minutes a week, at 80 to 100C. Cold is on the cold exposure page. Every row links to the exact moment it was said.
How hot, how long, and in what?
57 minutes a week is the figure he repeats, out of the same study that produced the 11-minute cold number. He gives it as a floor rather than a target and says it could just as easily be 55. Temperatures run 80 to 100C.
- Sauna
The base protocol. Sessions usually run 5 to 20 minutes, with 10 to 20 the range he emphasises most. Steam rooms and a Russian banya count, and he talks about both warmly.
cardiovascular conditioningsaid 6 different ways▶ 68 - Deliberate heat exposure
Start conservatively if you are not acclimated, around 15 minutes total, or three 5-minute bouts with breaks, then build. If you are acclimating for an event, start 8 to 10 weeks out rather than the final week. It is not a substitute for exercise.
heat tolerance and sweat capacitysaid 4 different ways▶ 16 - Hot-cold contrast therapy
Rounds of heat and brief cold. Wait a few minutes between the two rather than going straight from very hot to very cold. Also on the cold page.
mood and cardiovascularsaid 3 different ways▶ 14 - Sauna 4 to 7 times weekly for longevity
The cardiovascular cohort data. Two to three times a week already beats once a week by a wide margin.
said 2 different ways▶ 7 - Infrared sauna
He pushes toward traditional dry heat instead, the benefit tracks with actually raising core temperature.

When should I do it?
The rule that makes the whole topic make sense: heat makes you cool down afterwards, and the rebound is the effect. That is why heat belongs at night and cold belongs in the morning.
- Warm bath or shower before bed
Heat up so that you cool down after. Second half of the day, and not so long that it drains you. A sauna one to two hours before bed does the same job. Warming the extremities is how you dump heat from the core.
fall asleep fastersaid 5 different ways▶ 24 - Hot tub
A warm soak in a hot tub or bath in the evening, typically for 20 to 30 minutes, followed by a cool or warm shower to help the body shed heat. The goal is to trigger compensatory cooling and lower core body temperature by about 1 to 3 degrees, which can make it easier to fall asleep.
▶ 17 - Post-workout sauna for added training stimulus
Up to about 30 minutes, stacked onto the session rather than done separately. If you sauna early in the day, train straight afterwards.

What about growth hormone and mood?
- Weekly sauna intervals for growth hormone
Four 30-minute rounds at around 80C with 5-minute cool-downs. The biggest single claim in the topic, and the most demanding protocol in it.
▶ 5 - Safe heat exposure for mental health
The dynorphin mechanism. He is careful not to claim sauna treats depression. Repeated hot rounds with short breaks also come up as a way to lower cortisol.
said 4 different ways▶ 5 - Fasted sauna before sleep for growth hormone
Two to three hours after your last meal, to keep insulin low around the session.

Sick, injured, or too cold?
- Deliberate heat exposure during early infection
A hot shower or bath before sleep, as hot as you can comfortably take. Early in the infection only.
▶ 8 - Heat for injury recovery
Blood flow is what clears the debris out of an injury, and ice mostly numbs it. The exception is a fresh sprain or strain, where Sean Mackey gives the traditional cold for the first 48 hours and heat after that.
He’s said bothsaid 3 different ways▶ 8 - Glabrous skin rewarming
Palms, soles and face again, since the surfaces that shed heat fastest also take it back on fastest.
rewarms without burningsaid 2 different ways▶ 4
What do I need, and who should skip it?
- Avoid testicular heat exposure
Sixty to ninety days off groin heat, one full sperm-production cycle. If you sauna anyway, a cold pack or cooling underwear is the compromise he offers. Sits directly against the growth hormone section, and he does not always flag it.
protects sperm qualityHe’s said bothsaid 6 different ways▶ 15 - Rehydrate after sauna to replace sweat loss
Roughly 16 ounces of water per 10 minutes in there, taken before, during or after.
restores blood volumesaid 4 different ways▶ 7 - Wool sauna hat
Insulating the scalp lowers the brain-driven urge to get out, so you last longer. Not to make it hotter, which is what most people assume.
lets you stay in longersaid 3 different ways▶ 6 - Avoid hyperthermia
Heat stroke is the failure mode. Stop immediately if someone is overheating.
said 4 different ways▶ 4 - No alcohol during sauna use
Do not drink alcohol when using the sauna.
▶ 1 - Consult a physician before sauna if high risk
Elderly, prone to low blood pressure, post heart attack, or with existing heart disease.
▶ 1 - Avoid sauna during pregnancy
Avoid sauna use during pregnancy.
