Jet lag is a temporary sleep problem that happens when a person travels quickly across different time zones. The body’s internal clock becomes out of sync with the local time, leading to symptoms such as tiredness, difficulty sleeping, poor concentration, headaches, irritability, and digestive problems.
Jet lag is usually worse after long-distance travel and when crossing several time zones. Symptoms often improve gradually as the body adjusts to the new schedule.
Drinking enough water, getting sunlight exposure, adjusting sleep times before travel, and avoiding excess caffeine or alcohol may help reduce symptoms. Some people may also benefit from short-term sleep aids or melatonin.
