Putting this thing next to your pillow is like risking your life!

Undoubtedly, sleep is the most complete, systematic and effective way to rest, and it is also an important part of scientific health care. However, if you ignore some small things in sleep, it will be bad for your health and even shorten your life by several decades.

1. Wear a watch to sleep

Some people like to wear watches to sleep, which not only shortens the life of the watch, but is also detrimental to health. Watches, especially luminous watches, emit laser radiation. Although the amount is very small, experts believe that long-term accumulation can lead to adverse consequences.

2. Wearing teeth while sleeping

Some people have no teeth and live their lives wearing dentures. However, these people actually let their dentures sleep with them at night. In fact, this practice is very incorrect, because it is very likely that you will swallow your dentures while sleeping, which can endanger your life.

Therefore, it is best for people who wear dentures to remove their dentures and clean them before going to bed, which is beneficial to oral hygiene and can also help them sleep safely.

3. Wear a mask when sleeping

The Hawaii Institute for Civilization Diseases in the United States surveyed more than 5,000 women and found that women who wear bras for more than 12 hours a day are 20 times more likely to develop breast cancer than those who wear them for a short time or not at all. Women wear bras to show beauty or protect their breasts, but there is no need to do so at night.

4. Sleeping with the “machine”

American expert James Cook pointed out that various electronic devices, such as color TVs, refrigerators, mobile phones, etc., release a large amount of electromagnetic waves of different wavelengths and frequencies during use and operation, forming an electronic mist that affects the human nervous system and causes physiological function disorders. Although the amount released is extremely small, it cannot be ignored.

This type of people answer the phone or play with their mobile phones in bed. When they feel sleepy, they will put the mobile phone next to their pillow, that is, they fall asleep with the mobile phone. In fact, this will also emit a large amount of radiation, which is very harmful to human health.

5. Sleeping with makeup on

Some women, especially young women, are often too lazy to remove their makeup before going to bed. You should know that sleeping with makeup on will clog your skin pores, cause sweat secretion disorders, hinder cell breathing, and in the long run will induce acne and damage your face.

Therefore, it is necessary to remove makeup and wash your face before going to bed. This can promptly remove the irritation of makeup on the face and allow the skin to fully breathe. This can not only keep the skin moisturized, but also help you fall asleep early.

6. Sleeping with wet hair

Western medicine: Sleeping with wet hair can easily cause dizziness and nausea

People who have the habit of washing their hair before going to bed at night, but do not dry their hair carefully, so that a lot of water is retained on the surface of the scalp, are most likely to get sick, especially when the temperature is low at night in winter, and go to bed directly. In the middle of the night, you will feel numbness in the scalp, accompanied by a dull pain.

The next morning, you may experience an unexplained headache or dizziness, or even nausea in severe cases. Over time, this may lead to a disease called "subcranial venous plexus".

Traditional Chinese Medicine: If your hair is not dry during sleep, you are more likely to catch a cold

During the day, human Yang energy is weakest at midnight. After a day of exertion, people easily feel tired, which indicates that the activity of the body's "Wei Qi" has decreased, that is, the ability to resist wind and cold has decreased.

Therefore, if you wash your hair with hot water before going to bed, the dilated capillaries will be stimulated by the outside world, and the yang energy in the head will condense when it encounters cold, which will cause the body to freeze; thus, the capillaries in the upper respiratory tract will contract reflexively, the local blood flow will decrease, and the resistance of the upper respiratory tract will be reduced.

The viruses or bacteria that already exist in the area will take advantage of the opportunity to enter, grow and multiply, causing upper respiratory tract infection, resulting in cold symptoms such as runny nose, nasal congestion, headache and even fever. Therefore, it is easier to catch a cold if you go to bed with your hair wet.
