Can a deep sleep to relieve stress?
Source:Scientists believe that REM sleep is a natural sedative in that case, if the person gets it every night. Sleep can reduce anxiety overnight, by the reorganization of the connections in the brain
is not static: scientists invent new methods of research of human, are created for newer drugs and innovative diagnostic tools. But despite the development of medicine, sleep remains somewhat mysterious and not always explainable process. Until now, no one with certainty can not say about the necessary duration of sleep, because some argue that there should be no more than 8 hours, and the other part thinks that its duration should be no more than 6 hours. However, it is certain that during sleep our body recovers. But can sleep to completely get rid of stress and anxiety? New research scientists from the University of California will tell us how it is possible.
Brain activity during sleep
The Latest research of California scientists published in the journal , has confirmed reports that a full night of sleep, stabilize emotions, and sleepless night causes an increase in anxiety levels up to 30%.
Scientists at the University of Berkeley also found that REM sleep is best able to calm and relieve the anxious brain. REM sleep, also known as sleep with rapid eye movement (REM or REM), is characterized by the condition in which the nerve, the oscillations become highly synchronized, and the heart rate and blood pressure are decreased.
Thanks to the results obtained in the course of the study, researchers confirmed the presence of one of the strongest bonds between . The results suggest that sleep is a natural drug-free cure for anxiety disorders, which are increasingly diagnosed not only in adults but in children and adolescents.
In a number of experiments with the use of polysomnography, the researchers analyzed brain activity in 18 young people who watched an emotionally exciting video clips after a sleepless night and a full night's sleep. The level of anxiety was measured after each session using a test known as the assessment of the status of the alarm.
According to the results of brain scans after a sleepless night it was revealed the disconnection of the medial prefrontal cortex, which usually controls the anxiety, while the deeper emotional centers of the brain were overactive.
the Study shows that a sleepless night increases the anxiety level to 30%, thus disconnecting the medial prefrontal cortex
After a full night's sleep, the participants measured brain waves with that were installed on their heads. The results of the research “awake people” showed that the anxiety level decreased significantly, especially for those who had longer REM sleep.
In Addition to the laboratory studies, the researchers conducted an online study in which they tracked 280 people, regardless of age. The study has taken into account their level of sleep and anxiety for four consecutive days. The results proved that the quantity and quality that the participants got each night, predicted how anxious they would feel the next day.
