Sleep & Recovery
Sleep hygiene, chronobiology and recovery protocols — sauna, cold exposure and more.
4.6Melatonin
The hormone that governs your circadian rhythm — as a supplement it works better at resetting the body clock than as a classic 'sleeping pill.'
4.7Sauna (Thermal Heat Therapy)
Regular sauna use is linked in cohort studies to lower cardiovascular mortality risk — the strongest data comes from Finland.
4.4Chronotype
An individual, largely genetically determined preference for sleep and activity timing — ignoring it leads to a phenomenon known as 'social jet lag,' linked to worse metabolic health.
4.4Cold Plunges and Cold Exposure
Controlled exposure to cold water has become one of the most recognizable biohacking practices — with real, though more modest than pop culture suggests, scientific backing.
4.8Sleep
Sleep isn't a passive shutdown of the body — it's an active, highly organized biological process. Its shortfall (and, counterintuitively, its excess too) is linked to a measurably higher risk of death from any cause.
4.7Insomnia
Chronic difficulty falling or staying asleep isn't just a matter of 'sleep hygiene' — the best-studied intervention, recommended as first-line treatment, is cognitive behavioral therapy for insomnia (CBT-I), not sleeping pills.
