1, easy to harm the body's sleep habits.
1, wear a bra to sleep
Bras protect breasts, but sleeping with bras can bring diseases, especially breast tumors. Experts have found that women who wear bras for more than 17 hours a day have a higher risk of breast cancer than women who wear bras or don't wear bras for a short time. This is because the breast is compressed for a long time, lymphatic reflux is blocked, and harmful substances remain in the breast.
Step 2 wear jewelry to sleep
Some women don't take off their ornaments when they sleep, which is very dangerous. Some children are also used to wearing watches and bracelets to sleep, which is extremely harmful to health in the long run. First, some ornaments are made of metal. If they are worn on the skin for a long time, they will unconsciously cause chronic absorption and even accumulation poisoning (such as aluminum poisoning). ); Secondly, some ornaments with luminous effect will produce radium radiation, which is weak but will lead to adverse consequences over time; Thirdly, sleeping with ornaments will hinder the circulation of the body, which is not conducive to metabolism, which is also the reason why the local skin with ornaments is easy to age.
Step 3 sleep on your stomach
When you are tired of reading, just lie on your desk and sleep for a while, or some office workers put their hands under their heads during lunch break to catch up on sleep. In addition to affecting blood circulation, causing numbness and pain in upper limbs, it is also easy to increase intra-abdominal pressure, and over time, it will also produce "reflux esophagitis." Cause indigestion, affect the intake of systemic nutrients, and over time, the color will wither.
Step 4 sleep with your head covered
Many people like to cover their heads when they sleep, which is very harmful to their brains. I like to sleep with a quilt, but I don't know that it is easy to breathe with a quilt. With the increase of carbon dioxide concentration in the quilt, the oxygen concentration decreases continuously, and breathing humid air for a long time is very harmful to the brain. After a long time, it will lead to hypoxia, resulting in poor sleep and easy nightmares. I will feel dizzy, weak and depressed after waking up.
Step 5 sit and sleep
Due to the pressure of work, many office workers feel very tired when they get home. After eating, they sat on the sofa and began to doze off. Sitting and sleeping will slow down the heart rate, dilate blood vessels, aggravate brain hypoxia, and lead to dizziness and tinnitus.
6, slightly drunk to sleep
With the change of lifestyle, young women now have more nightlife, especially some professional women have more social activities and often fall asleep a little drunk. According to medical research, it is easy to suffocate after drinking alcohol before going to bed, usually twice a night, and the duration of each suffocation is about 10 minute. For a long time, people are prone to diseases such as heart disease and hypertension.
2. Healthy sleeping posture
(1) is on the left.
Robin Chutkan, a British gastroenterologist, said, "The symptoms of heartburn often get worse at night. Although we haven't figured out the exact principle, the symptoms are obviously relieved when people lie on their side. It is speculated that this posture makes the internal organs in a straight line, which helps to significantly reduce the flow of gastric acid into the esophagus, thus alleviating the pain caused by heartburn. " Therefore, if your stomach is uncomfortable, please choose the left sleeping position.
At the same time, a study by the University of Izmir in Turkey found that 40.9% of people who fell asleep on the left reported that they often had nightmares, while only 14.6% of people who fell asleep on the right reported this. Therefore, if you feel tired and nervous, you should avoid sleeping on your left side.
(2) Lie on your back
For long-term low back pain, it is recommended to sleep on your back, and put pillows under your head and knees to make your spine in a straight line, which can relieve low back pain or at least make you sleep comfortably for one night.
In addition, Dr. Gaisen Anson, a cosmetic plastic surgeon, said that when lying on your back, your face is relaxed and breathable, which is of great benefit to maintaining the vitality of your facial skin.
However, some studies have found that when lying on your back, due to the gravity of the earth, your tongue will fall to the back of your mouth, narrowing the respiratory tract. Compared with lying on your side, the chances of snoring and sleep apnea will double, and it will also cause serious health problems, such as daytime sleepiness, hypertension, diabetes and depression.
Therefore, people with snoring and sleep apnea symptoms should try to avoid lying on their backs.
(3) Fetal sleeping position
Amy Hope, a British osteopath, suggested that people should adopt fetal sleeping position. "When the body is curled up in the fetal sleeping position, the spine is flexible enough to change various sleeping positions at night." It can not only ensure enough relaxation of the body, but also help to relieve stress, especially suitable for people with great pressure and physical and mental fatigue.
But at the same time, the sleeping position of the fetus may aggravate the symptoms of neck pain. If you don't want to wake up with stiff neck or shoulder pain, use a relatively hard pillow to keep your neck and spine in a straight line while sleeping in fetal position. People with wide shoulders have thicker pillows, and people with low back pain put a pillow between their knees.
(4) Lying on the right side
Sleeping on the right side will give more space to the heart on the left side of the chest, which will help lower blood pressure and make the heart beat less quickly, which is beneficial to heart patients. Lying on the left side or the right side is also conducive to clearing the waste in the brain, spine and nervous system and preventing degenerative diseases such as dementia.
However, lying on the right side in the third trimester may cause fetal stillbirth. Researchers at the University of Auckland in New Zealand studied 155 women who gave birth to a dead baby and 3 10 women who gave birth to a live baby. It was found that sleeping on the right side would reduce the blood flow to the baby and increase the chance of stillbirth.
(5) prone
Sleeping on your stomach will make your internal organs in an ideal position, get enough rest and promote digestion. In addition, sleeping in prone position can effectively prevent snoring. A study by Hong Kong Shue Yan University also found that people who sleep in a prone position often have exciting dreams.
However, when lying prone, in order to facilitate breathing, you must turn your head to one side, which is easy to cause headaches, stiff neck, shoulder discomfort and other symptoms, and the pain will radiate to your arms.
