circadian rhythm
An organism's intrinsic approximately 24-hour cycle that regulates physiological processes such as hormone secretion, cell division, and hepatic detoxifying enzyme activity, influencing drug metabolism and treatment outcomes.
Timeline (last 90 days)
Almost every cell in the human body is regulated by circadian rhythms, from hormone secretion to cell division to the activity of liver detoxification enzymes, all of which exhibit pronounced temporal fluctuations.
Over the past two decades, the main thread of personalized medicine has been genomics; circadian rhythms provide a complementary variable—your genes do not change, but your biological clock drifts with age, daily routine, and disease state.
Light exposure not only affects circadian rhythms but is also related to skin health, brain health, and mitochondrial function.
Disruption of circadian rhythms affects the biogenesis and repair rhythms of mitochondria, which in turn affects the energy state of cells throughout the body.
The circadian rhythm is the body's approximately 24-hour physiological timing system, which relies on external environmental cues for continuous calibration, with light being the strongest calibration signal.
Fixing a consistent wake-up time has a more pronounced effect on regulating circadian rhythms than fixing a consistent bedtime.
The circadian rhythm is the body's approximately 24-hour physiological clock, primarily governed by the suprachiasmatic nucleus (SCN) in the hypothalamus of the brain.
The body's master clock is located in the suprachiasmatic nucleus (SCN) of the hypothalamus, which regulates the secretion rhythms of melatonin and cortisol through light signals, while the liver and digestive system have independent peripheral clocks.
