<p>According to studies, sleep deprivation is directly dependent on states of tension, anxiety, and nervous excitement. One sleepless night increases anxiety by 30%, and for some people, less than eight hours of sleep can lead to an increase in anxiety symptoms. On the contrary, deep sleep allows you to get rid of a stressful state even without the use of drugs.</p><p> In a study conducted at the University of California (Berkeley), scientists tried to find out the dependence of the level of anxiety on the amount of sleep. The 18 people who took part in the experiment were broadcast emotional videos after a night of good sleep, and then after a sleepless night. A special description and a brain scan using functional MRI allowed scientists to determine the level of anxiety of the study participants. So, during a brain scan, it was found that after a sleepless night, the part of the brain responsible for controlling anxiety levels was turned off, and the deeper emotional centers of the brain showed excessive activity. After a night of restful sleep, anxiety levels dropped significantly. Scientists have concluded that deep sleep reduces anxiety by rewiring the brain and helps regulate emotions, as well as preventing increased stress.</p><h2 style="text-align: center;"> <strong>How to improve sleep?</strong></h2><p> Here are some tips for improving sleep patterns.
