An experiment, performed on mice, enabled scientists to establish a link between lack of sleep and the risk of stroke. Insufficient or disturbed sleep time increases the risk of developing multiple pathologies, including cardiovascular disease.

Sleeping less than seven hours a day increases the risk of stroke, established researchers, whose study is published in the journal Nature.

Sleep is an integral part of life, they emphasize. Not getting enough sleep or not satisfactorily increases the risk of multiple pathologies, including those affecting the cardiovascular system.

Researchers performed an experiment on mice, which proved that sleep-controlled hematopoiesis (the renewal of blood cells) and protected against atherosclerosis (clogging of arteries with cholesterol and fat plaques).

Mice with fragmented sleep produce more Ly-6Chigh monocytes, develop more severe atherosclerotic lesions and produce less hypocretin – a neuropeptide that stimulates and stimulates awakening – in the lateral hypothalamus, the researchers conclude.

Atherosclerosis is a disease that affects the arteries of large and medium caliber and is characterized by thickening (for example by atheromatous plaques), hardening and loss of elasticity of their walls. In addition to high blood pressure, it is one of the factors that cause a stroke or stroke, which is a failure of the blood circulation that affects a more or less important region of the brain. It causes the death of nerve cells, which are devoid of oxygen and nutrients that are essential for their functions.
