Many people are forced to work in shifts.
In General, this mode is very convenient, because is released a lot of time on personal business. However, it is dangerous to health. Systems of the body, including sleep cycles, come into imbalance. As you know, prolonged violation of the sleep cycle provokes a rapid depletion of the bones.
The University of Colorado identified this relationship on the example of volunteers who for three weeks had to go to bed four hours later than the previous day. This created the effect that the day has 28 hours. 24 hours were allowed to sleep only 5.6 hours. Thus in the beginning of the experiment and after three weeks of lack of sleep got to test the blood. In it, scientists have searched for biomarkers related to bones.
It is reported that six volunteers were 20-27 years old, and four – 55-65 years. It was found in both age groups experienced a decline in the concentration of P1NP, a marker associated with bone formation. While young people, the concentration decreased more (27% vs. 18%). But the marker showing the degradability of old bone, did not change. This increases the risk of imbalance, when bone tissue is lost than is being generated new. The result can be osteoporosis and fractures.
