How effective is insomnia management for jet lag?

Travel across time zones leaves the body clock out of step with local daylight and bedtime. A consistent destination schedule gives the brain stronger timing cues. Morning or evening light, depending on the direction of travel, can shift the clock; mistimed bright light may prolong the mismatch. Sleep may improve gradually rather than after one night, and fatigue during the day is common while the adjustment occurs.

Adopt local sleep and wake times as soon as practical, seek appropriately timed outdoor light, and keep naps brief and early if you need one. Drink water, move gently, and avoid alcohol near bedtime. Keep the bedroom dark, quiet, and cool. Ask a clinician before using melatonin or sleeping medicines, especially with pregnancy, chronic illness, or other medicines.

Seek medical advice if sleep problems continue after your body should have adjusted, repeatedly affect driving or work, or occur with loud snoring, choking during sleep, severe low mood, or unusual agitation. Do not drive when very sleepy; arrange safer transport after a long journey.

Ask when to use light exposure, whether melatonin is appropriate for your travel direction and health history, how to handle medicines across time zones, and whether another sleep condition could be contributing.
