What happens in our brain while we sleep It is transcendental. One of the fundamental reasons why our body needs sleep is to achieve the emotional balance. “The irritability, impulsivityhe low moodthe consumption of stimulants and the lack of empathy and creativity are situations and states of mind linked to the bad dream“, points out the Doctor Javier Albares, sleep expert. In fact, the sleep disorders are closely related to anxiety disorders and of mood. For example, more than half of adolescents who experience sleepiness in class also experience lack of emotional control and mood disturbances.
While you sleep your emotions balance
Brain activity during sleep has three stages: wakefulness, non-REM sleep and REM sleep. During the second half of the night, REM sleep occurs, which is when the integration of new experiences with those of the past takes place. It is during the REM sleep phase when our emotional circuits adjust. “This is essential for us to have a correct emotional intelligence. If you look, then lose two hours of sleep a dayit is not only losing 25% of the hours we should sleep, but it also means losing approximately 70% of our REM sleep, with significant repercussions on our emotional control“explains the doctor.
What happens to your emotions if you deprive yourself of 2 hours of sleep
According to Matthew Walkerworld sleep expert, people who don’t sleep become 60% more reactivethat is, more violent and uncontrolled. According to the expert, these people show greater hyperactivity in the amygdala cerebral. His research shows that this is because there is another brain area involved: the prefrontal cortex. “The prefrontal cortex is like the executive director of your brain. (…) It is one of the most evolved regions of our brain. And one of the parts of the brain that controls is this deep emotional centerthe amygdala,” he explains.
More impulsive, more irritable
Different studies support this statement, such as those carried out by the Tel Aviv University and the Berkeley University. The first, published in the Journal of Neuroscience, found that those who do not sleep enough perceive and feel daily reality in a different way due to a greater emotional lack of control. In the Berkeley study, it was found that sleep 2 or more hours less than necessaryprovokes people more irrational and primary responses. Also the sleep expert of the Harvard UniversityJanet Mullingtonrecently recalled that “although subjectively you may feel good after sleeping fewer hours several nights, many more mistakes are made. In addition, sociability and optimism decrease and fatigue, tiredness, aggression and discomfort“.
