20 Things Women Should Never Do in Bed

1. Sleeping with makeup on: Some women, especially young women, do not remove makeup before going to bed. The cosmetics residue on the skin will clog the pores and cause sweat gland secretion disorders, which not only easily induce acne, but also damage the skin over time and accelerate the aging process.

2. Wearing a bra to sleep: Bras can protect the breasts, but wearing a bra to sleep can cause illness. Especially inducing breast tumors. According to relevant experts' research, girls who wear bras for more than 17 hours a day have a 20 times higher risk of developing breast cancer than those who wear bras for a short time or do not wear bras at all. This is because the breasts are under pressure for a long time, lymphatic return is blocked, and harmful substances are retained in the breasts.

3. Sleeping with accessories on: Some women do not have the habit of taking off accessories before sleeping, which is very dangerous. First, some ornaments are made of metal, which will wear on the skin for a long time and cause chronic absorption and even cumulative poisoning (such as aluminum poisoning) without knowing it; second, some ornaments with luminous effects will produce radium radiation. Although the amount is small, long-term accumulation can lead to adverse consequences; third, sleeping with ornaments will hinder the body's circulation and be detrimental to metabolism, which is also the reason why the local skin wearing ornaments is prone to aging.

4. Falling asleep while slightly drunk: With the change of lifestyle, young women now have a richer nightlife. In particular, some professional women have more social engagements and often fall asleep while slightly drunk. Medical research shows that drinking alcohol before bedtime can easily lead to suffocation after falling asleep, usually about twice a night, and each suffocation lasts about 10 minutes. If this continues for a long time, people are prone to diseases such as heart disease and high blood pressure.

5. Being angry before going to bed: Being angry before going to bed will make your heart beat faster, your breathing become rapid, and your mind become confused, making it difficult to fall asleep.

6. Eating too much before going to bed: If you eat too much before going to bed, your stomach and intestines will speed up digestion, and a stomach full of food will constantly stimulate the brain. If there are excitement points in the brain, people cannot sleep peacefully, just as Chinese medicine says: "If the stomach is not in harmony, you will not sleep well."

7. Drinking tea before going to bed: Tea contains caffeine and other substances, which can stimulate the central nervous system and make people excited. Drinking tea before bed, especially strong tea, will make it harder to fall asleep.

8. Vigorous exercise before going to bed: Vigorous activity will make the brain's nerve cells excited. This excitement will not calm down in a short time, so people will not be able to fall asleep quickly. Therefore, you should try to keep your body calm before going to bed.

9. The pillow is too high: From a physiological point of view, the pillow should be 8 to 12 cm. If the pillow is too low, it can easily cause a stiff neck, or too much blood flowing into the brain, causing a swollen head and swollen eyelids the next day. If the pillow is too high, it can affect the smooth flow of the respiratory tract, causing snoring. Moreover, using a high pillow for a long time can easily lead to neck discomfort or hunchback.

10. Sleeping with hands under the head: Sleeping with hands under the head will not only affect blood circulation and cause numbness and pain in the upper limbs, but also easily increase the intra-abdominal pressure, and over time will cause "reflux esophagitis".

11. Sleeping with your head covered: Because the weather is cold, many people are afraid of catching a cold, so they like to cover their heads with quilts when sleeping. However, they do not know that sleeping with your head covered can easily cause breathing difficulties. As the carbon dioxide concentration in the quilt increases, the oxygen concentration continues to decrease, and inhaling humid air for a long time is extremely harmful to the brain. Over time, it will lead to hypoxia, causing poor sleep and nightmares. After waking up, you will feel dizzy, weak, and listless.

12. Mouth breathing: Sleeping with your mouth closed is the best way to maintain your vitality. However, mouth breathing will not only inhale dust, but also easily irritate the trachea, lungs and ribs with cold air.

13. Sleeping facing the wind: The human body’s ability to adapt to environmental changes is reduced during sleep. Sleeping facing the wind can easily cause catching cold and becoming sick. Therefore, the sleeping place should avoid drafts and the bed should be kept a certain distance from windows and doors.

14. Sleeping while sitting: Many women work under stress and feel very tired when they get home. After eating, they sit on the sofa and start to doze off. Sleeping while sitting down will slow down the heart rate, dilate blood vessels, aggravate brain hypoxia, and cause dizziness and tinnitus.

15. Sleeping opposite each other: Some family members, such as couples, mother and children, often sleep opposite each other. This will cause one party to inhale mostly the waste gas exhaled by the other party, and the brain will lack fresh oxygen or have insufficient oxygen supply, which can also easily cause insomnia, nightmares, dizziness, fatigue, and mental depression after waking up. Because everyone's sleeping habits are different, pulling the quilt, kicking legs, snoring, etc. can easily cause the quilt to slip off, causing a cold and affecting sleep.

16. Sleeping with shoulders exposed: Some people have the habit of exposing their shoulders outside the quilt when sleeping, but they don’t know that the weather is cold in winter and the cold wind can easily invade the shoulder joints of the human body, causing stagnation of qi and blood in local meridians and joints, making it difficult to circulate, causing rheumatism, arthritis, and soreness and pain in the joints. Being attacked by wind and cold can easily cause colds, runny noses, breathing difficulties, dizziness and headaches.

17. Sleeping without turning off the electric blanket: Leaving the electric blanket on all night not only makes people feel dry mouth and tongue when they wake up, but also makes them more likely to catch a cold. The ideal temperature in bed when a person falls asleep is 33-35℃, and the relative humidity is 55%-60%. In this "micro-environment", a large number of blood vessels in the skin are in a state of contraction, and blood flow slows down, allowing the body to get sufficient rest and adjustment. If the electric blanket is heated for too long and the temperature inside the quilt remains too high, the blood vessels in the skin will dilate, blood circulation will speed up, breathing will become deeper and faster, and the ability to resist germs will decrease, which can easily lead to a cold. Therefore, the correct way to use an electric blanket is to turn on the power 10 minutes before going to bed, and turn off the power after the bedding is preheated. As long as you don't feel suddenly cold when you get into bed, it will be fine.

18. Storage of sleep: The human body cannot store sleep. Sleeping a few hours more just to stay up late is not of much help to the body. In fact, the human body only needs a certain quality of sleep. Sleeping too much will not only make you unable to fall asleep, but it will also be bad for your health.

19. Lack of sleep: The main way for the brain to eliminate fatigue is sleep. Long-term lack of sleep or poor sleep quality will only accelerate the decline of brain cells, and smart people will become confused.

20. Oversleep: Some women like to stay up late, even playing all night long. Although they make up for the sleep the next day, the adverse consequences caused by the disruption of their biological clock are inevitable, including sleepiness and difficulty concentrating during the day and insomnia and inability to fall asleep at night.
