A team of scientists from the universities of Manchester and Edinburgh made a very interesting discovery. It turns out that each person has a biological calendar, which helps the body to determine the seasons, and to adapt to them, according to Ghhauto.ru.
Scientists have conducted a series of experiments with the brain of sheep at different times of the year and We found a set of cells that respond to changes in the weather. In animals, they are responsible for functions such as reproduction and hibernation, while the people-activation of the immune system. These
“calendar cells” were found in the pituitary gland, which is located on the bottom surface of the brain and is responsible for the release of hormones in blood. They can stay in the two sostoyaniyah- summer and winter.
«It seems that in a short time, in the middle of winter or the middle of summer, all these cells are in one of these two states,” – explains Professor Manchester University Andrew Loudon.
Scientists liken this phenomenon to the daily rhythm that tells the body when awake and when to sleep, and the annual in charge of migration and hibernation in animals. In winter the day is shorter, melatonina- body produces more of the hormone of sleep.
«We have long found that melatonin plays an important role in long rhythms, but how and where it works, remained a mystery – says professor Loudon.
How do you determine the signs of affecting us at certain times of the year? People do not have the breeding season, do not hibernate, do not migrate like animals. Yet another sign of scientists have found. Upon the occurrence of colds in humans begin to activate genes for the immune system.
There is still much to be explored in this area, but the available data, laid a solid foundation for new discoveries.
