What is the term for a disturbance in the circadian rhythm of walking and sleeping when traveling across time zones?

The term for a disturbance in the circadian rhythm of walking and sleeping when traveling across time zones is "jet lag." This condition occurs when an individual's internal body clock is out of sync with the local time in a new time zone, often leading to symptoms such as fatigue, difficulty concentrating, disrupted sleep patterns, and a general feeling of malaise. Jet lag is particularly common among travelers who cross multiple time zones quickly, as the body takes time to adjust to the new schedule of light and darkness.

Understanding jet lag is important for athletes and travelers alike, as it can significantly impact performance and recovery. The body's circadian rhythm, which regulates sleep and wake cycles, can be influenced by exposure to natural light, sleep habits, and overall health, making it essential to manage these factors when traveling. The other terms, while related to sleep disturbances, do not specifically describe the phenomenon of time zone adjustment that characterizes jet lag.
