Question

Quizplus · Accepted Answer

Jet lag is caused by a disruption of the circadian rhythm, the body’s internal clock that regulates sleep-wake cycles and other physiological processes. When a person travels across time zones, their internal clock is no longer synchronized with the external day-night cycle, resulting in fatigue, insomnia, gastrointestinal problems, and other symptoms. To adjust to the new time zone, it is recommended to gradually shift one’s sleep and meal times, expose oneself to sunlight in the morning, and avoid napping or caffeine in the afternoon.
