The psychiatrist called an easy and pleasant way to become smarter

 Superficial sleep improves cognitive abilities and motor memory.

Taking a 15- to 20-minute afternoon nap improves cognitive abilities and increases concentration, says psychiatrist and sleep expert Chester Wu. His opinion is quoted by the Daily Mail

According to the specialist, it was previously believed that the body restores physical and mental strength only in the deep phases of sleep, but new data prove that shallow sleep is no less beneficial. Wu said that in the state between sleep and wakefulness, all body functions slow down: heart rate decreases, body temperature and blood pressure drop. This helps free up the body's resources and direct them to recovery.

Wu added that superficial sleep plays a significant role in the process of forming motor memory - memories of performing physical tasks. In addition, according to him, a short daytime nap is a good way to improve mental abilities and concentration.

The psychiatrist noted that the rate of surface sleep for each person is individual. He explained that during the night the brain dips into all phases and stays in each of them as long as it needs. Therefore, for a full rest and well-being, Wu advises not to focus on certain phases, but to try to follow the regime and give the body enough time to recover.
