Sleep OptimizationSleep Optimization: The Complete Guide
Sleep is the foundation every biohacker builds on, Huberman calls it the #1 performance enhancer. This guide covers the science of sleep stages, temperature regulation, light protocols, tracking with wearables, and the complete toolkit for deep restorative sleep.

Sleep OptimizationApigenin for Sleep: The Complete Guide
Apigenin is a flavonoid from chamomile that modulates GABA receptors for sleep support. Andrew Huberman popularized it as part of his sleep stack alongside magnesium threonate and theanine. This guide covers mechanism, dosing, stacking, and realistic expectations.

Glycine is an amino acid with direct sleep-promoting effects: it lowers core body temperature and improves sleep quality in human trials. At 3g before bed, it's one of the most evidence-backed, affordable sleep supplements. This guide covers mechanism, dosing, and how it fits the Huberman stack.

Sleep OptimizationCircadian Rhythm Optimization: The Complete Guide
Your circadian rhythm governs sleep, hormones, metabolism, and mood. Huberman and Walker's most foundational advice isn't a supplement or gadget, it's light exposure timing. This guide covers the complete circadian protocol: morning sunlight, evening protection, meal timing, and temperature.

Sleep OptimizationBlue Light Blocking: The Complete Guide
Blue light after dark suppresses melatonin and disrupts circadian timing. Amber-tinted blue blocking glasses are one of the most cost-effective sleep interventions. This guide covers lens types, timing, and why screen night mode isn't enough.

Sleep OptimizationMouth Tape & Nasal Breathing: The Complete Guide
Mouth taping encourages nasal breathing during sleep, which may reduce snoring, dry mouth, and fragmented sleep architecture. Popularized by James Nestor's 'Breath' and the Buteyko community, it's one of the cheapest sleep biohacks. This guide covers safe taping methods and contraindications.

Sleep temperature regulation is one of the highest-leverage biohacks with genuine evidence behind it, and three systems dominate the category: Eight Sleep Pod, BedJet 3, and Sleepme's Dock Pro (the modern successor to Chilipad, now owned and re-engineered by the same Sleepme team). Eight Sleep uses hydronic water cooling built into a mattress cover with deep sleep-stage automation. BedJet uses forced air instead of water, with no wet components at all. Sleepme's Dock Pro is the direct descendant of the original Chilipad, focused purely on precise temperature control without the smart-home layer. This guide compares the technology, noise, subscriptions, price, and who should buy which. Want the science and budget tiers first? Read Sleep Cooling.

Sleep OptimizationSleep Cooling: Mattresses, Pads & Temperature Protocols
Sleep onset requires a 1–3°F core body temperature drop. Hot sleepers, couples with different preferences, and anyone chasing deep sleep often invest in active cooling — from $60 fan setups to $3,000 smart mattresses. This guide covers the science, equipment tiers, and Matthew Walker's temperature targets. For a head-to-head buy decision, see Eight Sleep vs BedJet vs Chilipad.

Sleep OptimizationNSDR and Yoga Nidra: The Complete Guide
Non-sleep deep rest (NSDR) is Andrew Huberman's umbrella term for yoga nidra and related guided protocols that drop you into a deeply relaxed, often hypnagogic state without requiring a full nap. This guide covers the sleep and stress evidence, how to run a session, and when NSDR beats caffeine.

Melatonin is a hormone, not a harmless supplement. Used correctly — low dose, short term, timed early — it helps jet lag and circadian shifts. Used nightly at high doses, it may disrupt natural production and sleep architecture. This guide separates appropriate use from default drugstore habits.
