It will lead to dull and dry skin color and large pores. < P > Sleeping late will miss the time of skin metabolism, and the epidermis will accumulate more old waste keratin and cannot fall off naturally. In addition, nerve excitement at night stimulates exuberant secretion of sebaceous glands, resulting in an increase in skin oil production and accelerated water loss, which will lead to large pores and dry and rough skin in the long run.

4. Causes dark circles and bags under the eyes

The skin of the eyes is very thin, only a quarter of the face, and the blood vessels are also very thin. Night is the physiological rest time of the human body. Without rest, the blood circulation around the eyes will be too slow due to excessive fatigue, which will deepen the skin color, thus forming dark circles and bags under the eyes. If the bags under the eyes are too large, they will form shadows and make the dark circles look darker. And dark circles will not go away for a while, making people look haggard and old.

5. It leads to poor hair quality and less hair loss

Do you find yourself losing a lot of hair at a young age, and your hair quality is very poor? There are many reasons for hair loss, and staying up late is one of them. Because the health of hair needs sufficient nutrients, and the nutrients needed by hair are provided through the capillaries under the scalp, staying up late will make the body in a state of fatigue for a long time, thus affecting the supply of nutrients. Naturally, hair will fall off, have poor hair quality, and even have white hair.

Not only does it affect the facial features, but research shows that lack of sleep can also cause serious health risks, such as obesity, heart disease and diabetes. Insufficient sleep will disturb the biological clock and make people's mental state unstable in a day.

most people have the luck of "it's okay to sleep less for a while", but they don't know that as long as they sleep less than 6 hours a day and less than a week, their bodies will be overwhelmed.

Here are some ways to improve sleep:

1. Fixed schedule

Many students should have the experience that when they just had a holiday, they woke up every morning because their bodies remembered the schedule during school. However, after a long holiday, I went to bed late and got up late, and my work and rest were out of order again.

If you can keep this routine all the time, you can naturally go to bed early and get up early without disturbing your biological clock.

2. Comfortable sleeping environment

When people fall asleep, they will secrete melatonin, a "sleep hormone". In order to have a good sleep, they should first put themselves in a good sleeping environment and adjust the switch of parasympathetic nerve to rest mode.

a quiet and airy bedroom and a comfortable bed are the foundation of a good sleep. Dim the lights and light your favorite incense if necessary to relax yourself and help you fall asleep.

3. Don't drink coffee or alcohol before going to bed

Caffeine can stimulate the nervous system, and has a certain diuretic effect, which easily leads to insomnia.

Many people think that drinking alcohol before going to bed can promote sleep, but studies have proved that although it can make people fall asleep quickly, it keeps sleep in the shallow sleep period, making it difficult to enter the deep sleep period and reducing the quality of sleep.

4. Turn off the mobile phone and other electronic products

The mobile phone is definitely a big obstacle for us to fall asleep every day. Once we start to brush the mobile phone, our brain will become more awake and it will be difficult to fall asleep on time. It's best to turn off your mobile phone before going to bed and restrain your desire to see it.
