If you have sleep problems, how do you know that these are related to your REM (Rapid Eye Movement) sleep? The main characterics of REM sleep disorder is an abnormal behavior during REM sleep with sudden arms and legs movements and vocal sounds as a reaction to vivid dreams.

We know that sleep is crucial for our brain ability to function, to memorize and to learn. A recent study shows that getting only half a night’s sleep disturbs the brain’s ability to unlearn fear-related memories. That might make people especially vulnerable to fear-related disorders such as anxiety or posttraumatic stress disorder.
