What should you know about minimizing jet lag?

Jet lag is a temporary mismatch between your internal body clock and the day-night schedule at your destination. Crossing time zones can cause difficulty sleeping at the local bedtime, early waking, daytime sleepiness, poor concentration, headache, or digestive upset. The direction and length of travel, your usual sleep pattern, and how quickly you change schedules all influence the experience. It is different from ongoing Insomnia, although disrupted travel sleep can make existing sleep problems harder to manage.

Before departure, move bedtime and waking time gradually toward the destination schedule when practical. During the journey, rest, drink water, limit alcohol, and avoid heavy meals close to intended sleep. After arrival, use daylight at the appropriate local time, keep naps brief if needed, eat on local time, and choose light activity. Set an alarm to protect a regular wake time. A Travel Health Consultation can help when work, illness, medicines, or a complex itinerary affect sleep planning. Do not use sleeping tablets or melatonin without checking suitability.

Speak with a clinician if sleep disruption continues after your body has had time to adjust, daytime sleepiness makes driving unsafe, or symptoms are severe or unusual. Seek urgent help for chest pain, severe breathlessness, fainting, confusion, or a sudden neurological change; do not assume these are jet lag. Repeated travel-related sleep problems may need a tailored Insomnia Management plan.

Ask when to shift your sleep schedule, how to time light exposure, and whether any medicine or supplement is suitable with your health conditions. Discuss safety-sensitive work, driving, and what symptoms would need assessment rather than self-care.
