Most villagers in the north have utensils for heating in winter, called charcoal pots. Old people lack knowledge of electricity and dare not use electricity for heating. In winter, we use charcoal and firewood to keep warm.
1, poisoning
Winter is the season of high incidence, among which children are the most.
Burning coal will produce, burning charcoal and firewood, and insufficient combustion of coal fire will produce gas. The new house with cement structure is more airtight than the adobe house, and the gas cannot be emitted, which is easy to cause poisoning.
After carbon monoxide poisoning, people will feel sleepy and gradually lose consciousness. If no one wakes up beside them, it may lead to death.
After carbon monoxide poisoning, how to rescue the family? Reminder: immediately open the doors and windows for ventilation, and transfer the patient to a ventilated place, stay in bed, keep quiet and keep warm.
Ensure that the respiratory tract is unobstructed, and the comatose person should tilt his head to one side to prevent the vomit from inhaling into the respiratory tract and causing suffocation. For coma or convulsion, an ice pack can be placed on the head to reduce brain edema. And quickly sent to a hospital with hyperbaric oxygen treatment conditions for treatment.
2, easy to get heat shock erythema
Heating for a long time in winter and close contact with heat sources are easy to cause heat-induced erythema.
Heat shock erythema is a kind of reticular capillary dilation and pigmentation caused by long-term exposure to infrared rays. Generally speaking, heat-induced erythema refers to slight redness, pain, itching and other uncomfortable symptoms on the skin, which usually appears after long-term continuous contact with heat sources, although it has not yet reached the level of skin burns.
The skin presents reticular erythema, and then the erythema will gradually deepen to blue-purple, then pigmentation, skin blackening, and even blisters.
The mild symptoms are temporary. Don't touch the heat source any more. Apply some moisturizing cream. 1-2 days later, the erythema will subside on its own. If heated for a long time or repeatedly, erythema will gradually deepen into blue-purple, accompanied by pigmentation, and gradually turn into brown pigment spots.
This kind of pigment spot belongs to inflammatory pigment spot, although it will eventually disappear, but the personal situation is different, and the disappearance time is long and short. Some people have a good metabolism and soon disappear. Some people have bad metabolism, and it may take about half a year to disappear.
Therefore, Health Network suggests that when you are heating, the human body should keep a distance of about 15 cm from the warm source. For electric blankets, car heating pads and other heating items that are in contact with the body, they should generally be kept when they are not cold. It is best not to have close contact with the skin, especially when sleeping at night, to avoid the direct contact of heat source with the skin unconsciously.
3, dry cold
It is feasible to keep warm with fire for a short time, but it must not be long. One reason is that the burning of carbon will produce unhealthy gases, and another very important reason is that carbon monoxide will be produced. In addition, long-term fire will make the skin dry and easy to get angry. The most important thing is that the elderly have low resistance and large temperature difference after fire, which will lead to colds and is not conducive to winter.
