Question

Quizplus · Accepted Answer

A person's circadian activity cycle is affected by exposure to light and darkness. Spending a period of time in seclusion, away from sunlight, can cause a person's internal clock to become desynchronized with the activity of others. This is because our internal clock relies on external cues like daylight to regulate our sleep-wake cycle, hunger signals, and other bodily functions. While the other choices may affect a person's health and well-being, they are not directly related to circadian rhythms.
