How to Defeat Jet Lag, Shift Work & Sleeplessness

About this video

Huberman explains how to defeat jet lag, offset shift work effects, and address sleeplessness using the circadian system, building on prior episodes about light, exercise, and temperature. The central landmark, Huberman explains, is the temperature minimum: knowing where it falls lets a person use light, temperature, and exercise on either side of it to shift the clock in a desired direction. Huberman explains that a hot shower produces a cooling effect afterward, while a cold shower or ice bath produces a rebound increase in body temperature; applied at the wrong time relative to the temperature minimum, he argues, these push the clock the wrong way, while applied correctly a cold exposure after the minimum can phase-advance the clock so sleepiness comes earlier that night. Huberman emphasizes that understanding mechanism gives flexibility rather than neurotic attachment to a protocol. For short trips, Huberman advises that if a trip is 48 hours or less, stay on your home schedule, even if that means scheduling meetings accordingly.

Key takeaways

• Huberman identifies the temperature minimum as the landmark for shifting the circadian clock.
• Huberman explains that hot showers cool the body afterward while cold exposure rebounds temperature upward.
• Huberman argues that timing light, temperature, and exercise around the minimum determines shift direction.
• Huberman advises staying on a home schedule for trips of 48 hours or less.
• Huberman frames mechanism knowledge as freedom from rigid protocols.
