Doctors at the Massachusetts Hospital discovered that a sleep of less than seven hours a day could increase the risk of stroke.

The study was conducted on mice. The rodents were divided into two groups, the first sleeping no less than seven hours a night and the second group being constantly awake, according to a publication of the journal Nature.

As a result, in sleep-deprived mice there was an increase in leukocyte levels and an increase in plaque formation leading to atherosclerosis. At the same time, no changes in weight or cholesterol levels were observed in the groups.

The researchers then discovered the hormone hippocrine brain, responsible for alertness, which is involved in the production of white blood cells in the bone marrow during sleep.

The low level of the hormone causes plaque formation, as well as an excessive increase in the number of leukocytes.

Carotid artery disease occurs when filling the blood vessels that carry blood to the brain and head (carotid arteries), which increases the risk of stroke, a condition known as carotid artery disease. Medical emergency occurring when the blood supply reaching the brain is interrupted or diminished. Great.

In another context, the experts suggested that short periods of sleep during work can increase productivity, as well as other benefits, without the need to leave the workplace.

Another study found that taking antidepressants and stress exposure associated with trauma and anxiety are possible causes of behavioral disturbances during sleep.
