What should you know about huberman jet lag?

Your brain and body use a daily rhythm to time sleep, alertness, digestion and hormone activity. Rapid travel moves you to a new clock before that rhythm has adjusted. Jet lag can cause difficulty sleeping at the local bedtime, daytime sleepiness, poor concentration, mood changes, headache or stomach upset. The direction and size of the time-zone change, travel fatigue, light exposure and sleep before the trip all influence the experience. Insomnia is a separate condition, although travel-related sleep disruption can make existing sleep problems more noticeable.

Before departure, gradually move sleep and wake times toward the destination when practical. After arrival, use daylight and activity at the local times that support the new schedule, keep meals regular and limit long daytime naps. A dark, quiet bedroom can make local-night sleep easier. Hydrate and avoid driving or demanding tasks when very sleepy. Discuss melatonin or other sleep aids with a clinician or pharmacist, especially if you take other medicines, are pregnant or have a health condition. A travel health consultation can help with a complicated itinerary.

Seek urgent help for chest pain, severe breathlessness, fainting, sudden weakness, new speech trouble, severe confusion or a sudden severe headache. Arrange medical advice if sleep disruption persists well after your travel schedule has settled, daytime sleepiness makes driving unsafe, or symptoms suggest another illness. Do not assume every post-flight symptom is jet lag.

Ask: How should I shift my schedule for this route? When should I seek help for ongoing insomnia or sleepiness? Is a sleep aid suitable with my medicines and health conditions? How can I stay safe if I must drive or work while adjusting?
