What should you know about jet lag tired?

Your sleep-wake rhythm still follows your departure time while light, meals, work, and social activity follow the destination. This mismatch may cause daytime sleepiness, poor concentration, irritability, early waking, or difficulty sleeping at night. A headache can occur as well. These symptoms commonly improve as your body clock adjusts, but tiredness can make driving, operating equipment, or making complex decisions unsafe.

Use the destination schedule as soon as practical: get up, eat, and seek daylight at local times. Keep evening light low when you are preparing for bed, and make your room quiet, dark, and comfortably cool. Drink water, choose light meals, and use gentle movement to stay alert. A brief nap may help, but a long or late nap can make night sleep harder. Avoid using alcohol to force sleep, and ask a clinician before taking melatonin or sleep medicines. See Insomnia Management for sleep-focused strategies.

Get urgent help for chest pain, severe breathing trouble, fainting, new weakness, confusion, or a sudden severe headache. Arrange medical advice if sleepiness prevents safe daily activities, symptoms are worsening rather than settling, or sleep disruption continues after you have had time to follow a local routine. A clinician can consider other causes such as insomnia or illness rather than attributing every symptom to travel.

Could another condition be contributing to my daytime sleepiness? Is a sleep aid appropriate with my medicines or health conditions? What travel schedule would suit my next trip?
