Circadian rhythm is the internal clock that makes us feel tired at nighttime and awake during the day. The circadian rhythm is an extremely intricate mechanism, with an internal control system that responds to external signals.
Despite its complexity, scientists think that circadian rhythm is one of life's most primitive adaptations. All living things have circadian rhythms, including animals of all sizes, plants, and even fungi and bacteria.
This list is full of circadian rhythm facts that should make you realize how important it is that you stay faithful to your circadian clock. This internal "clock" regulates more than just sleep - we rely on circadian rhythm to regulate metabolism, insulin and glucose levels, hormone production, core body temperature, brain wave activity, and cell regeneration. Almost all of our biological processes can be tied back to circadian rhythm, and messing with these biological rhythms can lead to serious health issues.So read on to learn about what your circadian clock does, and how to keep it working properly - it can truly be a matter of life or death.
