In winter, in order to keep out the cold, many people are used to laying electric blankets on their beds, which helps them fall asleep surrounded by warmth. However, modern health theory holds that there are many disadvantages in using electric blankets in winter, and careless use will affect human health, especially for the elderly and children, which should be paid more attention to.

Electric blankets are not suitable for some people. The electric blanket is heated by electric current passing through the heating wires in the electric blanket. Although this current is very weak, the electric blanket has a large area, which will have a great impact on some sensitive people.

The old man is weak and ill. If electric blankets are used, electromagnetic radiation will affect the blood circulation and heart function of the elderly, causing diseases or aggravating the condition.

Pregnant women exposed to electromagnetic radiation will cause fetal malformation or abortion.

The baby's nervous system is not well developed and is very sensitive to electromagnetic radiation. Using electric blankets is also easy to cause diseases.

Overheating of electric blanket is harmful to health. Although the electric blanket now has a constant temperature control system, some people like high temperature and will use it for a long time. Although some people have set a low temperature, under the pressure of quilts, bodies and mattresses, local temperatures cannot be emitted, and high temperatures can also occur.

The human body will have some adverse effects on physiology in high temperature environment. The high temperature of male seminal vesicle will lead to poor sperm development and low quality. Exposure of women to radiation will affect hormone secretion and lead to infertility. Children are accustomed to the high temperature environment, their adaptability to the cold is reduced, and they are more likely to get sick. Therefore, when using electric blanket, we must master the appropriate temperature, rather low than high.

Pay attention to safety when using electric blankets. First of all, the electric blanket should be heated in advance, and the power supply should be turned off when falling asleep, so as to avoid accidents such as electric leakage and fire after falling asleep. Second, the electric blanket must pay attention to check whether it is flat and not folded, otherwise it will easily break or short-circuit due to fatigue at the folded part, which will easily lead to a fire. Third, the electric blanket should not be in direct contact with the body, but should be separated by sheets or mattresses.
