A good night's sleep is absolutely essential for maintaining the rhythms of our body’s internal clock.. And this mechanism, in turn, is required to maintain activity and youth..

It has long been known that a good night's sleep makes us energetic and fresh throughout the day.. And now, for the first time, biologists have explained why rest at night so well prepares the human body for all sorts of intense types of activity. Research results published by Nature Cell Biology. It was carried out on mice and showed that the mechanism of the internal clock increases the ability to maintain the activity of our bodies. And since over the years the accuracy of this watch has strayed, this may be one of the causes of aging, many of whose processes are still a mystery.

This study sheds new light on the intracellular matrix of the body, which provides structural and biochemical support to cells in the formation of connective tissue such as bones, skin, tendons and cartilage. About half of our body weight is the same matrix, and half of this matrix is \u200b\u200bcollagen. Scientists have long proved that it is fully formed by the time it reaches the age of 17.

And now, for the first time, two varieties of fibrils were discovered (proteins with an elongated filamentous structure in which the ratio of the long axis of the molecule to the short axis is from 80 to 150) - similar to the ropes of collagen structures that are used by cells to form tissues.

Thick fibrils (approximately 200 nanometers in diameter, which is a million million times smaller than a pin head) are permanent and remain in our body throughout life unchanged from 17 years. However, thin fibrils (50 nanometers in diameter) break down as we subject the body to various kinds of stress during the day, but recover at night.. Scientists observed secrets of collagen using mass spectrometry, as well as the most advanced electron microscopes. Measurements were taken every 4 hours for two days..
