Circadian rhythms are biological oscillations that recur with a period of approximately one day. Health issues related to circadian rhythms include jet lag, shift work, seasonal depression, and time-of-day variations in response to medical treatments.
Circadian rhythms are, essentially, daily cycles of biological activity. They are based on a 24-hour period and influenced by the most regular variations in the environment like the alternation of night and day. Circadian rhythms can influence so many aspects of your wellbeing. Your sleep-wake cycles, hormone release, body temperature and other important bodily functions are all regulated by circadian rhythms. Abnormal circadian rhythms have been linked to various sleep disorders. They have also been associated with obesity, diabetes, depression, bipolar disorder and seasonal affective disorder. The importance of maintaining your circadian rhythms is well indicated.
