Jet lag and Andrew Huberman: what should you know?

Jet lag reflects a mismatch between your internal body clock and local time. Light is a powerful timing cue, while sleep, meals, and activity also provide signals. The useful question is not simply which tip to copy, but when a cue should occur for the direction of travel and the schedule you need to follow. People can also experience daytime sleepiness, difficulty sleeping, or headache during the adjustment.

Start with a stable local wake time, planned daylight exposure, regular meals, and a calm evening routine. Avoid experimenting with intense light schedules, fasting, melatonin, or sedating medicines without professional advice; timing and interactions matter. Keep a nap brief if you need one, and do not use any plan that leaves you too sleepy to drive or work safely. A travel health consultation can tailor the approach to your itinerary and medical history.

Talk to a clinician if sleep disruption lasts, repeatedly affects functioning, or is accompanied by symptoms that do not fit a simple travel adjustment. Seek urgent help for collapse, chest pain, severe breathing difficulty, or new severe confusion. Personal advice is especially important if you have a sleep disorder, take regular medicines, or need to perform safety-sensitive tasks soon after arrival.

Ask which parts of a light-based plan apply to your flight direction, whether supplements are suitable, and how to protect alertness during travel and work.
