Circadian Rhythm


Circadian Rhythm refers to the natural, internal process that regulates the sleep-wake cycle of an individual. It is a 24-hour cycle that is influenced by external factors such as light and temperature. In aviation, circadian rhythm is an important consideration for pilots and crew members who may experience disruptions to their sleep patterns due to long-haul flights, shift work, and time zone changes. Disruptions to circadian rhythm can lead to fatigue, decreased alertness, and impaired performance, which can have serious safety implications. Therefore, airlines and regulatory bodies have implemented policies and procedures to manage and mitigate the effects of circadian rhythm disruptions on aviation personnel.
