The weather in Guangdong has cooled down a lot recently, which can be regarded as the “success of taking off summer” and returning to the winter appearance of previous years. Some people jokingly say that this is not cooling, and it is clearly quick freezing. With the arrival of cold winter, many people like to sleep with electric blankets on at night. On the one hand, it has a good heating effect, and on the other hand, it has a relatively good protective effect on the elderly, rheumatic patients and the weak. However, the frequent news of improper use of electric blankets makes us worried. How can we use electric blankets properly?
be careful when using electric blankets
dermatitis
In real life, some people will have pimples the size of a needle tip after using an electric blanket. Most of the papules start on the back, buttocks and back of the thighs that contact the electric blanket, and then gradually spread to the whole body. The patient feels itchy and sleepless, which affects rest and work. According to the research, this kind of situation mostly occurs in the elderly, frail, allergic to the system, and patients with diabetes nephropathy and hepatobiliary and gastrointestinal diseases. This is because, after a long time of power on, the electric blanket continues to dissipate heat, making the moisture in the human skin evaporate continuously and become dry, which is caused by the stimulation of the pyrogen to the skin.
respiratory tract infection
Under normal circumstances, the human body dissipates heat mainly through breathing and skin. After using the electric blanket, the temperature in the quilt is relatively high and the indoor temperature is relatively low. As a result, it is hot inside and cold outside. The capillaries of the mucosa of the upper respiratory tract such as the nose, pharynx, trachea and bronchus are expanding, and the breathing is deeper and faster than usual.
On the one hand, the cold air in the room irritates the respiratory tract mucosa, resulting in dry mucosa and prone to pharyngitis, laryngitis and bronchial diseases; On the other hand, the temperature in the quilt is high, and the head exposed outside the quilt is easy to sweat. In deep sleep, hands and feet will also stretch out of the quilt, which is easy to catch cold and cause upper respiratory tract infection.
dehydration heat
After using the electric blanket, some people will have dry lips and throat, hoarseness, flushing and other symptoms the next day, and infants will also have fever, restlessness, crying and other phenomena, which is called “dehydration fever” in medicine. Because the human body contains a lot of water, 60% of the adult’s body weight is water, and the water in infants and young children accounts for 70% – 80%. In order to maintain life, the human body needs to supplement 2500 ml of water every day.
Infants and young children are in the period of growth and development. When they sleep, their metabolism is also vigorous. According to scientific research, 10% of the water in the body evaporates when the body temperature rises by 1 ℃. On the other hand, the absorption, transportation of nutrients, excretion of metabolites, sweating and heat dissipation all need to consume water in the body. Therefore, the use of electric blankets should prevent dehydration heat.
infertility or fetal malformation
Because the high temperature generated by the electric blanket will affect the ability of testis to produce sperm and the sperm activity is not high, the electromagnetic field generated by the electric blanket will have some adverse effects on the female endocrine system, so it is not suitable for newlyweds who want to have good children. For pregnant women, the magnetic field generated after the electric blanket is energized can directly affect the normal development of the fetus through the pregnant woman, and even lead to abortion or fetal malformation.
how to use the electric blanket correctly:
1. The electric blanket should not be in direct contact with the human body, but can be covered with a blanket or bed sheet.
2. Do not use the electric blanket on metal or hard objects with sharp protrusions.
3. When the electric blanket is not in use, the power must be cut off to prevent accidents.
4. Avoid repeated folding at the same position to prevent the heating wire from breaking due to folding and causing fire. If “not hot” occurs due to long-term use, it should be sent to the manufacturer for repair.
5. The power on time should not be too long. Generally, the power should be turned off before going to bed. In any case, it should not be used all night.
6. The skin of the elderly is relatively insensitive to cold and heat. Once the electric blanket is overheated, there is a risk of burning the skin, so use it with extreme caution.
7. Those who often use electric blankets should increase drinking water appropriately.
8. Pay attention to the safe service life of electric blankets. Generally, the safe service life of electric blankets is 6 years.
