What should you know about i am jet lagged?

Your internal body clock helps time sleep, alertness, appetite, and digestion. Crossing time zones changes the local schedule before that clock has adjusted. You may have difficulty sleeping at night, daytime sleepiness, headache, poor concentration, mood changes, or altered appetite. The direction and number of time zones crossed, travel fatigue, dehydration, and disrupted routines can affect how strongly you feel it. Symptoms should gradually fit the local schedule.

Follow local meal and sleep times, seek daylight during the local day, and keep evenings dim and quiet when preparing for sleep. Drink water, use light activity to stay awake, and take a short nap only if needed. Avoid driving or safety-sensitive work when very sleepy. Limit alcohol and late caffeine. If sleep remains difficult, insomnia management advice or a travel health consultation may help with future journeys and medication choices.

Seek medical advice if sleep disruption or daytime sleepiness persists well beyond the expected adjustment period, prevents work or safe driving, or keeps recurring after travel. Get urgent help for chest pain, severe breathing difficulty, fainting, new weakness, confusion, or a sudden severe headache. A clinician can consider insomnia, medication effects, mood symptoms, or another illness when the pattern does not match recent travel.

Ask how to time light exposure, sleep, meals, caffeine, or any medicine around your itinerary. Share your departure and arrival times, travel direction, usual sleep pattern, current medicines, and whether you have headache, difficulty sleeping, or unsafe daytime drowsiness.
