Dreams eliminate the painful memories

Scientists from the University of California say that the time spent in sleep, helps to overcome the painful memories.

The researchers found that during REM sleep the body effect of stress on the system time stops, that is, at a time when a person dreams, his brain processes emotional experiences and helps to cope with the painful and traumatic memories.

Opening researchers offers a new explanation for the fact that people with posttraumatic stress disorder (PTSD), such as war veterans, a long time can not recover from stressful events and suffer from nightmares.In addition, scientists have proposed, and his answer to the question why we have dreams.

Psychotherapy in

dream dreams during REM sleep due to the unique neurochemical processes in the brain that make a person actually receives psychotherapy each night.This allows you to release tension arising due experienced a day of shocks and stresses.

However, in people with PTSD such therapy may not work as effectively.Thus, the sharp sounds or br

ight flashes could cause them memories of traumatic events and make relive the horror of what happened again, because the memories were not properly handled during sleep and still have a strong emotional coloring.

dreams Benefits

phase of REM sleep, during which the person sees the dream, normally takes about 20% of the total duration of sleep.Previous studies have shown that people suffering from such disorders as depression or post-traumatic syndrome, sleep disturbed.

Given that a person spends much of his life, namely, its third in a dream, scientists still have not agreed on the appointment of sleep.

However, this study found a link between sleep, learning processes, memory and mood regulation

Thus, scientists have once again confirmed the importance of REM sleep.During the fast phase reactivated memories are processed, linked with other events and analyzed, but in a state free of stress factors.

Study The study involved 35 healthy young men were divided into two groups.Each participant showed 150 emotional images, twice - with a break at noon.

Brain activity was assessed using magnetic resonance imaging.One group of participants saw pictures in the morning and evening, that is, the interval between scans was awake.The second group of participants first saw pictures in the evening and the second time - in the morning, after a night's sleep.

Those who slept during the break, have shown a marked decrease in the emotional response to the images.MRI scans showed a significant decrease in amygdala activity (part of the brain responsible for emotions), which allowed rational prefrontal cortex to take control of emotional reactions.

In addition, during REM sleep there is a decrease the level of adrenaline - a hormone associated with stress.

Experiencing emotional experience stress-free environment, we wake up the next morning, feeling that emotions have lost their poignancy and tenderness.We feel better and realize that we can cope with stress and cope with anxieties.
