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

Andrew Huberman

Jun 11, 2026

Episode description

In this ⁠Huberman Lab Essentials⁠ episode, I discuss science-supported tools to improve sleep by supporting a healthy circadian rhythm using key behaviors and environmental cues. I explain specific morning, afternoon and evening behaviors that will increase daytime alertness and support deeper, more consistent sleep at night. I also cover sleep supplements, the effects of caffeine, alcohol and THC on sleep, as well as practical strategies for managing jet lag and shift work.

Mindsip insights from this episode:

Shift your sleep schedule by hacking your internal clock

Your body's lowest temperature occurs about two hours before your typical wake-up time, and light exposure around this "temperature minimum" can shift your entire sleep schedule.

#circadian

#sleep

Optimize artificial light to enhance sleep and wakefulness

The artificial lights in your home are too weak to properly wake you in the morning but are bright enough to disrupt your sleep at night.

#light-therapy

Utilize inexpensive lights for effective morning light exposure

Inexpensive options like selfie ring lights or LED tablets can work just as well as expensive daylight simulators for morning light exposure.

#LED

Get morning sunlight to regulate sleep cycle

Getting sunlight within 60 minutes of waking triggers a healthy cortisol peak that sets a timer for you to fall asleep about 16 hours later.

#sunlight

Delay morning caffeine for sustained energy

Waiting 90 to 120 minutes after waking to drink caffeine can provide a longer arc of energy and prevent an afternoon crash.

#coffee

Get afternoon sunlight to safeguard sleep quality

Getting sunlight in the late afternoon can inoculate your nervous system against the negative effects of artificial light later in the evening.

Take hot baths to enhance sleep quality

Taking a hot bath or using a sauna in the evening facilitates sleep by causing a compensatory drop in your core body temperature.

#bath

#sleep

Take cold showers to boost morning alertness

A short (1-3 minute) cold shower in the morning paradoxically increases your core body temperature, which helps you wake up.

Exercise caution with commercial melatonin due to high dosages

The dosages in most commercial melatonin products are far higher than what your body produces naturally and can disrupt other hormone systems.

#melatonin

#supplement

Implement sleep supplement stack for improved rest

A supplement stack of Magnesium Threonate (145mg), Apigenin (50mg), and Theanine (100-400mg) taken 30-60 minutes before bed can greatly improve sleep.
