Jet lag: a practical plan for long-haul travel

Use sleep timing, daylight and a personalised plan to help your body adjust

Jet lag: a practical plan for long-haul travel

Jet lag happens when rapid travel across time zones disrupts your normal sleep pattern. It often improves within a few days as your body clock adjusts, but careful planning can make the transition easier.

What can I do before and during the flight?

Start the journey well rested. On the flight, stay hydrated, limit excess caffeine and alcohol, and try to sleep when it is night at your destination. Gentle movement during a long flight also supports general comfort.

How can I adjust after arrival?

  • Move meals and sleep to local time as soon as practical
  • Spend time outside during daylight
  • Avoid long daytime sleeps that make night-time sleep harder
  • Keep the first days manageable while your body clock adjusts

Do I need jet lag treatment?

Medicines are not usually needed. Short-term melatonin may be considered for some adults, but timing matters and it is not suitable for everyone. A pharmacist should check your route, health and other medicines before recommending a treatment plan.
