An Outline of Research Studies On Humans' Sense of Rhythm

Summary of research on human rhythm * Folkard et al. Six students spent one month apart from external clues. Using computer tasks, record body temperature and activity, measure the emotional level every 2 hours. One student was asked to regularly play a bagpipe to see if the rhythm of the body was affected by external clues. The results of Folkard et al. Confirmed the presence of several internal clocks.

Chen and Yoo are studying circadian rhythms and the 24-hour physiological pattern of most organisms (including humans) is tracked everyday. These rhythms are millions of years in the world. The system is old, rugged and flexible. It is the product of organism's body clock and environmental cues - the most remarkable is the product of the sun and many other factors, and they control our behavior, hormone levels, sleep, body temperature and metabolism. The so-called "master clock" that controls the circadian rhythm of humans consists of the suprachiasmatic nucleus (SCN), a pair of cell populations containing the gene that performs this function (Clock, Npas 2, Bmal, Per 1, Per 2, Per 3, Cry 1, Including Cry 2). ), Located in the hypothalamus of the brain

The first thing about circadian rhythm studies (also known as time biology) is that, with a few exceptions, all creatures on the planet follow a circadian clock. From daffodils to sparrows, from zebras to humans, the light of the sun all follows the pattern of the sun. In 1729, French scientist Jean-Jacques Dortu de Milan recorded the intrinsic or internal circadian rhythm oscillation first observed in the leaves of Mimosa pudica. Even in perfect darkness, plants will continue rhythm everyday. This led to the conclusion that the factory relies not only on external clues and trends in the times, but also on its own internal clock.

Nearly everything in the sun follows the sun's rhythm, a 24-hour cycle where the earth rotates billions of years. Even humans, animals, plants, flies, fungi and even bacteria follow this custom called circadian rhythm (meaning "around" death "daytime"). Specifically, the circadian rhythm is the result of a permanent interaction between the body clock and environmental cues - most notably the sun, and many other factors - actions, hormonal levels, Control sleep, body temperature and metabolism. .

Most people are aware of our environment, waking up and sleeping according to the natural light of the sun. According to new research, intestinal microorganisms and their circadian rhythms are in harmony with our natural rhythm. When we feel that our retina lacks light, our hypothalamic hypothalamic nucleus suggests the production and release of melatonin. This tells us the cells of our body and we will soon sleep. Intestinal microorganisms also react to melatonin. Most of the melatonin produced by our body eventually resides in our gastrointestinal tract. As the major bacteria sense this melatonin, they start to flock and become more active. The importance of this behavior is not clear, but these intestinal microbes will undoubtedly change our own sleep-wake cycle behavior
