AP PSYCHOLOGY

Detailed explanation-1: -Chronobiology is the study of circadian rhythms. One example of a light-related circadian rhythm is sleeping at night and being awake during the day. The Average Teen Circadian Cycle image shows the circadian rhythm cycle of a typical teen.

Detailed explanation-2: -The regulation of sleep is processed by the homeostatic physiology of the circadian rhythm, the sleep/wake cycle. Circadian rhythm is the 24-hour internal clock in our brain that regulates cycles of alertness and sleepiness by responding to light changes in our environment.

Detailed explanation-3: -Circadian in Latin means “around or approximately” (circa) “a day” (diem). Circadian rhythm is the name given to your body’s 24-hour “internal clock.” This internal clock controls your body’s sleep-wake cycle.

Detailed explanation-4: -Notable examples of circadian rhythms include the sleep-wake cycle, daily rhythms in body temperature, and day-night rhythms in cortisol and melatonin production4, 5, 33.

Detailed explanation-5: -These repeating 24-hour cycles are called the circadian rhythm. Your body tries to align your sleep-wake cycle to cues from the environment, such as when it gets light or dark outside, when you eat, and when you are physically active.
