Sleep-Wake Cycle

The sleep-wake cycle is a natural biological rhythm that regulates the timing of sleep and wakefulness in humans and other animals. It is controlled by the circadian system, which is located in the suprachiasmatic nucleus of the hypothalamus in the brain. The sleep-wake cycle is influenced by external factors such as light and temperature, as well as internal factors such as hormones and genetics. In space and astronautical engineering context, understanding the sleep-wake cycle is important for designing spacecraft and habitats that support healthy sleep patterns for astronauts during long-duration missions.
