What to expect from insomnia management for jet lag

Jet lag occurs when the internal body clock is out of step with the local time. You may feel sleepy during the day, alert at night, wake early, or find concentration and digestion affected. The direction and number of time zones crossed influence the adjustment, and symptoms often improve as the body clock adapts.

Insomnia management aims to give the body strong time cues. Light exposure, meals, activity and sleep timing can all signal the new schedule. Sleeping medicines or melatonin are not suitable for everyone and may interact with medicines or cause next-day drowsiness.

Adopt local bedtime and wake time as soon as practical. Seek daylight at a planned time, keep the bedroom dark and quiet at night, and limit bright screens close to bedtime. Use short naps only when needed, avoid late caffeine and alcohol, and keep activity gentle if you feel sleepy.

For a trip, plan the sleep shift around departure and arrival, then follow the timing consistently. Ask a clinician or pharmacist before using sleep aids, especially if pregnant, older, or taking sedating medicines. Do not drive or operate machinery if drowsy.

Arrange medical advice if sleep difficulty continues after your body has had time to adjust, repeatedly disrupts work or safety, or occurs with loud snoring and pauses in breathing. Seek urgent help for confusion, severe agitation, fainting, chest pain or thoughts of self-harm. Persistent insomnia may have another cause that needs assessment.

Ask when to seek light exposure, whether a sleep aid is safe with your medicines, how to plan naps, and which symptoms would suggest a sleep disorder beyond jet lag.
