"It's so dry! Especially in the afternoon, drinking a lot of water is still useless, and the whole person feels flustered. Ms. Ma, a citizen, told reporters that since the winter, she can always feel dry mouth, consciously drink more water, but it has not improved, and even at night when she falls asleep, she will unconsciously wake up by thirst. In fact, the reporter learned and found that there are not a few citizens who feel like Ms. Ma in winter. Whether it's in the office or at home, whether it's heating, air conditioning, floor heating or radiators, it always seems uncomfortable to stay in a heated room all the time. Could this be a "heating sickness"?

"The so-called 'heating disease' from the medical point of view, that is, the temperature during the day in winter is around zero degrees, after turning on the heating, the temperature difference will be relatively large, and it is rare to open doors and windows for ventilation, which will lead to poor air circulation throughout." After the air is dried by the high temperature for a long time, it will make our body's immune function and resistance decline. Bai Qiaohong, chief physician of the Respiratory Department of Nanjing Second Hospital, answered the reporter's question, she said that dry air will have some symptoms, such as nosebleeds, and irritability when hot, and sometimes dizziness, weakness, etc., will be called "heating disease.".

Bai Qiaohong introduced that because the indoor air quality is not very good and the indoor temperature is high, this also provides an environment for the breeding and spread of indoor pathogens, "so it will induce some respiratory diseases, such as bronchitis, asthma and so on." Of course, "heating disease" is not only caused by the respiratory system, some people have chest tightness and even induce more serious diseases are likely to be caused by improper use of heating. "After sweating more, older people have increased blood viscosity, insufficient blood volume, leading to a decrease in blood pressure, angina and other symptoms of cardiovascular diseases. There are also children who may have nasal mucosa that is not well developed, and the air is particularly dry, which will cause nose bleeding. ”

So is there a way to prevent or alleviate the signal of "heating sickness" in the body? "First of all, the temperature of the room should be controlled at 18-24 degrees, and the humidity is recommended to be controlled at 50%-60%." Bai Qiaohong told reporters that while ensuring the appropriate temperature and humidity, it is also important to open the window for ventilation and keep the indoor air clean. "You can also plant some green plants, such as green lotus and hanging orchid, which can bring a lot of water in itself, and secondly, can also purify the air." Nowadays, in the face of dry air, many people will also choose to use a humidifier to add a humidity to the working and living environment, but Bai Qiaohong especially reminds that when using a humidifier, it is necessary to add pure water or distilled water, and pay attention to changing water regularly every day to avoid long-term use of bacteria.

Avoiding "heating disease" to find stubble is also a very important part of self-maintenance. "It is recommended that everyone drink more water every day, at least 2,000 milliliters. Eat more warm fruits and vegetables, such as apples, pears, tomatoes, radishes, and eat less spicy. In addition, the temperature of the bath water in winter should not be particularly high, and the occurrence of pruritus can also be reduced," Bai Qiaohong reminded.
