How long does insomnia management take to work for jet lag?

Jet lag occurs when your internal body clock is out of step with the local day and night. You may feel sleepy at unusual hours, wake during the night, or struggle to fall asleep even when tired. A consistent sleep schedule, timed light exposure, and a calm bedtime routine support adjustment, but they cannot instantly reset the body clock.

Follow the local bedtime and wake time as consistently as you can. Seek daylight during the local morning when you need to move your body clock earlier, and reduce bright light late in the evening. Keep naps brief and early, avoid late caffeine, and use the bedroom for quiet, cool sleep. Medicines or melatonin may not suit everyone, so discuss timing and safety with a clinician before using them.

Arrange medical advice if poor sleep continues after your travel adjustment period, repeatedly affects daytime safety or work, or comes with loud snoring, pauses in breathing, severe anxiety, or unusually elevated energy. Seek urgent help for chest pain, severe breathlessness, confusion, or thoughts of self-harm.

Ask whether your symptoms fit jet lag, which sleep and light schedule matches your travel direction, and whether any medicine or supplement could interact with your conditions or current treatments.
