Scientists at the Medical College of Wisconsin (Medical College of Wisconsin), United States, found that rats that lack of sleep, there are pathologies of bone and bone marrow. In particular, slowing growth and the formation of new bone, and the bone marrow is reduced fat and doubled the number of precursor cells of platelets. Scientists suggest that similar changes may occur in humans. The results of this study are published in the journal Experimental Biology and Medicine.
A team led by professor of neurology, cell biology, neurobiology and anatomy Carol Everson (Carol Everson) studied the peculiarities of bone tissue in rats chronically enough sleep. They found that at a constant rate of absorption, ie, destruction of bone tissue, these rodents practically stops the formation and growth of new tissue, which leads to increased bone fragility and frequent fractures.
Moreover, scientists have noted changes in the bone marrow. The amount of fat in it has decreased dramatically, and the number of platelet precursor cells grown in 2 times. As a consequence of these changes will not only reduce the plasticity of the bone marrow, but also increased the concentration of platelets in the blood of rats. This, in turn, may increase the risk of thrombosis and even heart attack and stroke.
If the same processes can be observed with a lack of sleep in humans, it may partly explain why the elderly are prone to suffer "senile" insomnia, increased risk of osteoporosis and slow the growth of new bone. But scientists say that in today's society lack of sleep has become quite common for young people. Therefore, they need to consider the consequences of lack of sleep for your health and to review their busy schedules.
