Sleep helps people be smarter

Many people believe that the bigger their memory is, the worse they can remember everything. However, in reality, they cannot remember everything for a long time. And the latest research shows that sleep is the cause.

National Geographic magazine said that the latest research by American scientists showed that, when sleeping, the human brain will conduct screening of human memories, choose which ones to remember, what Any need to forget quickly. Scientists also believe that this process can help improve learning capacity and help people think better.

Jessica Payne, from the University of Notre Dame, USA, the head of the research program said: ' When people sleep, the brain does not only know what people have gone through to remember more deeply but also to choose. which ones to remember, which ones need to be forgotten '.

Usually, the things that impress most people often involve emotions. When looking at a scene that makes people feel heavy, such as an old car, what one remembers most is the gloomy scene of the car, not the palm trees on the side. after. This is especially true when it is tested after a deep sleep.

Thus, the human brain does not completely store the whole scene but reorganizes, remembers only the important content that makes a strong impression on people. Other content will gradually be forgotten.

Jessica Payne's group also found that, when sleeping, the areas involved in strengthening memories and emotions on the brain are much more powerful than when people are awake.

Payne argues that, through this process, sleep can help people improve their academic ability, judgmental ability and fostering the ability to abstract thinking.

However, this process also has its negative downside. For example, the brain can only choose to remember negative experiences and ignore other experiences. This condition often occurs in people who are extremely depressed or have lost their emotional balance due to a loss in life.

Payne believes that further research can help people better understand how information is remembered and how the brain remembers them. This will be very beneficial in treating mental trauma.
