Sleep is also very careful, many sleeping habits can be dangerous to health. Sleep is a daily necessity for everyone, sleep can replenish one’s brain power, physical strength, help women anti-aging, but bad sleeping habits can affect the health of the human body, and can even kill you. Now we’ll list some of the common saving habits in sleep, each of which may be the culprit of destroying your health. Habit one: immediately after waking up folded quilt Many people think that immediately after waking up folded quilt “neat and clean”, but in fact this is not a practice conducive to health, because it is possible to make mites more rampant. According to scientists, even in a very tidy home, there are at least 15 million bedding mites in each bed. These mites, which are much smaller than 1 mm, survive on the dander naturally shed by the body and produce substances that cause various allergic symptoms in the body. They are often found in the center of warm cotton wool and can also scurry onto people at night, taking pleasure in causing various skin diseases. But mites need the moist moisture of the bedding to grow, and if the moisture and water disappear, all kinds of mites will eventually die of thirst. That is why you should not fold up the comforter immediately after getting up. Because such folding will make the bacteria, water vapor and harmful gas on the comforter wrapped up and difficult to be distributed and harmful to human health. The correct approach is: after waking up, you should casually turn the quilt over, or on a chair, and open the doors and windows, so that moisture and gas naturally emitted, after an hour and then fold the quilt, or turn the quilt over and spread it on the bed, so that the quilt in the moisture and gas naturally emitted. Habit 2: Sleeping in winter without turning off the electric blanket The use of electric blankets does not have much impact on health, but overnight use will bring health problems. However, many girls love warmth, often all night long, electric blankets do not turn off, the result is not only wake up feeling dry mouth, but also easy to catch a cold. This is because the ideal temperature in the nest is 33-35 degrees and the relative humidity is 55-60% when sleeping. In this “small environment”, a large number of blood vessels in the skin are in a contracted state and the blood flow is slowed down, so the organism gets sufficient rest and adjustment. If the heating time of electric blanket is too long and the temperature inside the nest is too high, the blood vessels of the skin will expand, the blood circulation will accelerate, the breathing will become deeper and faster, and the ability to resist germs will decrease, which will easily lead to cold. So the correct use of electric blankets is to turn on the power 10 minutes before going to bed, and turn off the power when the futon is warmed up, as long as you do not feel the sudden cold when you enter the nest. Habit 3: like to sleep with the head covered This will make the air does not circulate, the oxygen in the nest is not enough to make the body organs do not get enough oxygen supply, it can also induce dreaming, and often a series of nightmares, people are easy to wake up from the dream. After waking up, people will feel dizzy, chest tightness, weakness, and lack of energy. Habit 4: to sleep with clothes instead of quilts Some people are used to wearing sweaters, sweater pants or cotton undershirts in winter to sleep. As people in the sleep state torso, limb muscles are relaxed, and the more sweet sleep, the more relaxed muscles. Wearing too many clothes to sleep will affect the relaxation of the muscles of the whole body, which is not conducive to blood circulation and respiratory function. Clothes wrapped in pressure prone to nightmares, suffocation and night terrors and other diseases occur.
