Sleep is important

Are you too busy for a day?

Tell yourself secretly:

"Tonight, you must go to bed early!"

This issue of "How much Science Know" is revealed for you

About the secret of sleep

The lack of sleep

May make you lose a lot

Why do we need sleep?

Sleep is a very important part of our lives.

You may not realize that we will experience several different sleep stages when falling asleep, which helps our body rest and recovery and prepare for the new day.

There are two main parts of human sleep cycles: non-fast eye sleep (Non-Rapid Eye Movemen (NREM) and Rapid Eye Movement (Rem).

Every night, we will circulate between non -fast eyes and fast eye movement sleep.

The body will first enter the period of non -fast eye movement, and then enter the short -term rapid eye movement and sleep (in fast eye movement sleep, the eyes will move quickly in all directions), and then continue to circulate this process.

Non-fast eye movement sleep is divided into three stages, each stage lasts for 5-15 minutes. After all the three stages are over, the body will enter fast eyes and sleep.

In the three stages of non -fast eye movement, brain activity is getting slower and more difficult to wake up, which helps the body to recover from one day of work and study. The short -term memory storage area is transferred to the outer layer of the brain with unlimited storage capacity.

However, if we do not have sufficient sleep time at night, the memory of the day is transmitted from the short -term memory of the brain to the outer layer of the brain. The next day the brain will have no room to effectively create new memories, which will make new things learn new things more difficult Essence

Haima (blue) is like USB, as a short -term memory memory experienced on the day.

Fast eye movement sleep occurs at the end of each cycle. As shown in the figure below, the fast -moving sleep time will become longer and longer.

The last two Rem phase will account for about 60%of REM sleep per night. The first Rem stage may only last about 5-10 minutes. The final Rem stage lasted about 1 hour. If you only sleep for 6 hours, you will miss about 60%of ReM sleep.

Quickly eye movement sleeping is the sleeping stage of dreaming. Have you ever experienced trying to escape from something in your dreams, but your legs can't move quickly?

This is because the body enters a paralysis state when it is fast -moving sleep, which means that our body does not want to move.

Studies have proved that fast eye movement sleep is very important for creativity.

Studies have shown that when people encounter a problem that cannot be figured out, if they get good fast eye movement that night, they are more likely to have the ability to solve the problem after waking up the next morning.

Because in each sleep cycle, the time for fast eyes to move and sleep will increase with time. The longer the sleeping time every night, the more fast eye movement. Therefore important.

Sleep is especially important for adolescents

The brain of adolescents will experience important development in adolescence.

It is like a magical hardware that can change and adapt to different environments, and this function is to the formation of the marrow sheath (a material that wraps the brain connection).

The marrow sheath is an insulating material that wraps the brain connection, which helps the brain signal to move faster.

As shown in the figure above, the marrow sheath is a layer of membrane wrapped outside the axis of the nerve cells. Due to the formation of myelin sheath, the brain cells called neurons can communicate with each other at a higher speed.

If you imagine neurons as a slide, then the formation of the marrow sheath is like putting a lot of soap and water on the slide to help spread the information around the brain faster.

The increase of the pulp sheath helps us to think, solve problems and plan the future more deeply. Studies have shown that rapid eye movement plays a very critical role in helping this brain development.

Therefore, if adolescents do not get enough fast eyes to sleep, brain development will be affected, which will affect their adult life.

And the adolescents with sufficient sleep, their brain is stronger and better, which helps them continue to grow and feel happier!

Scientists have determined how much sleep for people of different ages to maintain health and happiness. Data show that adults should sleep at least 7-9 hours a night, and teenagers should sleep at least 8-10 hours a night.

For people of all ages

Start tonight, be sure to go to bed early!

Let your brain have the best opportunity

Make you smarter, stronger, and happier

More creative!
