Why does jet lag happen, and how does it affect the body?

Jet lag is a known sleep disorder that results from moving too fast between different time zones so that a person’s biological clock cannot adjust itself. The main sign is a temporary mismatch between our biological clock and the local clock. Our biological clock is synchronized with the cycles of light and darkness of day and night. Therefore, it increases our alertness during the day and the need for sleep at night. Any change in the biological clock occurs slowly. Therefore, switching between different time zones causes a mismatch between the individual’s alert-tired feelings and the local hours of light and darkness.

The symptoms of Jet lag mainly include insomnia and daytime fatigue but may also manifest in a depressed mood, impaired physical function, impaired cognitive ability (thinking), and even gastrointestinal problems. The symptoms of flare-ups continue until the biological clock is coordinated with the local clock. Although flying is a mild and transient medical disorder, it can lead to wrong business or professional decisions.
