Jet lag is a temporary sleep disorder that occurs when a persons circadian rhythm is out of sync with the time zone they are in. It is caused by traveling across different time zones, which disrupts the body's internal clock. Symptoms of jet lag can vary from person to person, but some common ones include:
- Difficulty falling asleep (insomnia)
- Drowsiness during the day
- Headaches
- Lack of focus or concentration
- Extreme tiredness (fatigue)
- General feeling of being “off” or not like yourself
- Upset stomach
- Mood changes, such as irritability
Overall, you can expect more severe jet lag when you fly farther, as greater distances require your body to make a bigger adjustment. Jet lag can also cause dehydration, which can contribute to some of the symptoms. Symptoms are usually temporary, but they can last anywhere from a few days to a few weeks. Strategies to reduce jet lag include maximizing your exposure to natural light, staying hydrated, and avoiding caffeine and alcohol.
