What should you know about jet lag no more?

You may notice that you fall asleep and wake at appropriate local times, feel more alert during the day, and can eat meals without forcing the schedule. A lingering headache, poor focus, or early waking suggests that adjustment may be incomplete, although those symptoms can also have other causes. Improvement is usually gradual rather than a single moment, and repeated travel can shift the body clock again.

Keep wake time, meals, activity, and bedtime reasonably consistent after recovery. Use natural daylight earlier or later according to your schedule, keep evenings calmer, and protect enough time for sleep. Before another trip, plan the transition around the destination and avoid arriving severely sleep deprived. If symptoms recur on every journey, discuss a personalised travel plan with a healthcare professional.

Seek advice if sleep difficulty or daytime sleepiness remains disruptive after your routine is stable, or if symptoms appear without a recent time-zone change. Get urgent help for severe confusion, fainting, chest pain, major breathing difficulty, or a sudden severe headache. Mood changes with very little need for sleep also need prompt assessment.

Ask what signs show that your body clock has adjusted, how to prepare for your next route, and whether light exposure or another treatment is appropriate. Mention recurring headaches, insomnia, snoring, or daytime sleepiness.
