United States scientists discovered that sleeping helps the brain process strong emotional experiences associated with traumatic memories. Investigators from the California University in Berkeley found out that the chemicals that produce stress “turn off” during sleeping hours.
This phase is known as “rapid eye movement sleep” or REM, which is more present in dreams. Scientists discovered that there is a relation between sleeping and memories.
Researchers explained why people with Post-Traumatic Stress Disorder (PTSD) like war veterans show difficulty to recover from painful experiences and suffer from recurring nightmares. Scientists believe that their research can help people afflicted with PTSD. (AV)
