What should you know about jet lag symptoms how long does it last?

Sleep may be broken at night while tiredness appears during the day. The adjustment can feel slower after a larger time difference, travel across several time zones, poor sleep on the journey, or irregular light exposure after arrival. Headache, appetite changes and reduced concentration may improve alongside the sleep pattern.

There is no single deadline that applies to every traveller. Symptoms should trend toward improvement as local routines become established. Symptoms that stay unchanged, worsen, or occur without a clear travel trigger deserve consideration of another cause, including insomnia or an illness acquired during travel.

Adopt local wake, meal and bedtime cues soon after arrival. Seek daylight at an appropriate local time, keep evenings dim before sleep, and make the bedroom comfortable for rest. Gentle daytime movement may support alertness, while alcohol and late caffeine can make nighttime sleep less predictable.

Keep naps short and earlier rather than sleeping through the local afternoon. Protect safety by postponing driving or demanding tasks when you are very sleepy. If symptoms are lingering, record sleep times, naps, medicines and caffeine; this gives a clinician useful information. Ask before using melatonin or sedating medicines.

Seek urgent help for chest pain, severe breathing difficulty, fainting, sudden weakness, confusion, or a sudden severe headache. Book medical advice if sleep disruption is not gradually easing, daytime sleepiness makes work or travel unsafe, or vomiting, fever or pain develops. A clinician can assess travel exposures, medicines and other sleep problems.

Does my symptom pattern fit jet lag? What could explain symptoms that are lasting longer than expected? Should I change my light or nap schedule? Are any of my medicines making sleepiness worse?
