Andrew Huberman: Essentials: Sleep Toolkit for Optimizing Sleep & Sleep-Wake Timing

Key Takeaways

• View sunlight within the first 30-60 minutes after waking for 5-30 minutes (depending on cloud cover) to trigger cortisol release and set your circadian rhythm.
• Avoid sunglasses during morning sunlight viewing, but corrective lenses are fine.
• If waking before sunrise, use bright artificial lights, but note they cannot replace sunlight for triggering cortisol release.
• Limit artificial light exposure at night, as even dim light can disrupt sleep.
• Consider a cold shower (1-3 minutes) in the morning to increase core body temperature and enhance wakefulness.

Products & Gear Mentioned

• Sunlight simulators or daylight simulators (expensive) for areas with limited sunlight.
• Cheaper alternatives like ring lights or LED tablets for indoor light exposure.
