vuorokausirytmien
Vuorokausirytmien, also known as circadian rhythms, are biological processes that occur on a roughly 24-hour cycle and are synchronized with the Earth's rotation relative to the Sun. These rhythms are essential for the proper functioning of living organisms, including humans, and are regulated by an internal biological clock. The master regulator of circadian rhythms is the suprachiasmatic nucleus (SCN) in the hypothalamus, which receives light information from the retina via the retinohypothalamic tract.
Circadian rhythms influence various physiological processes, including sleep-wake cycles, hormone secretion, body temperature, and metabolism. They
The study of circadian rhythms is a multidisciplinary field that involves researchers from various disciplines, including
