The physiological changes that follow these clocks are known as circadian rhythms. Because the endogenous period of these rhythms are approximately but not exactly 24 hours, these rhythms must be reset by external cues to synchronize with the daily cycles in the environment. [1] This process is called entrainment. One of the most important cues ...
Light therapy can also be used to treat circadian rhythm sleep disorders. These disorders are caused by discrepancies between one’s circadian rhythm and the light/dark cycle of the environment. People with a sleep disorder experience insomnia or hypersomnia .

A circadian rhythm (/ s ər ˈ k eɪ d i ə n /), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours. Circadian rhythms can refer to any process that originates within an organism (i.e., endogenous ) and responds to the environment (is entrained by the environment).
Temperature influences the body’s circadian rhythm, which regulates sleep-wake cycles, says Dr. Vendrame. In other words, your body’s temperature tells you when to sleep and when to be awake.
Light exposure in the morning can regulate circadian rhythms, according to Dr. Raj Dasgupta, an ABIM-quadruple board-certified physician specializing in internal medicine, pulmonology, critical ...
Sleep duration is also shorter. As the infant ages, sleep begins to follow a Circadian rhythm and sleep duration increases. Infants nap frequently. Infants are also particularly vulnerable during sleep; they are prone to suffocation and SIDS. As a result, "safe" sleep techniques have been the subject of several public health campaigns. [5]
Any biological process in the body that repeats itself over a period of approximately 24 hours and maintains this rhythm in the absence of external stimuli is considered a circadian rhythm. [4] It is believed that the brain's suprachiasmatic nucleus (SCN), or internal pacemaker, is responsible for regulating the body's biological rhythms ...
