＂Top Ten Steamed Cities in China＂ released! These organs are the most vulnerable in sauna days!

"Go out for five minutes and sweat for two hours" … For many people, the sultry sauna day may be the most difficult time in summer. On July 23rd, China Weather Network official Weibo released "Top Ten Steamed Cities in China". By analyzing the average sauna days from 1991 to 2020, the cities with the most steamed weather were counted. ①

"Top Ten Steamed Cities in China" was released, and Shanghai topped the list. As can be seen in the figure, the number of sauna days during the summer heat in Shanghai was as high as 8.8 days, which was the highest for "steaming". Nanchang and Guangzhou ranked second and third with 8.6 days and 7.9 days.

Wang Weiyue, a meteorologist of China Weather Network, introduced in Weibo, the official website of China Weather Network, on July 23rd that in addition to the top ten "steaming" cities, Haikou, Fuzhou and other cities are located by the sea, and the daily maximum wind force often exceeds Grade III, so the number of days that meet the sauna standard is relatively small, and they can’t occupy a place in the rankings, but the sultry feeling is also obvious. ① On July 8th, according to Weibo, a weather network in China, there are two main types of heat in summer: one is dry heat, which is characterized by high temperature, strong solar radiation, low air humidity and large temperature difference between day and night; The other is sultry, characterized by high temperature, high air humidity, no wind or small wind. ②

Sauna day means that when the highest temperature is ≥32℃ and the daily average relative humidity is ≥80%, the somatosensory temperature will exceed 45℃, giving people a feeling of sultry weather similar to a sauna. The weather in China once launched a poll on "Which is more uncomfortable, dry or muggy". The results showed that 32,000 netizens chose "sultry sauna", accounting for 80%, and "sultry sauna" won by rolling. Why is the sultry "sauna day" even worse? Wang Weiyue, a meteorologist at China Weather Network, explained that in hot weather, people often sweat to cool down, and sweat evaporates to absorb heat, which can take away the body’s heat. In the "sauna days", sweating and evaporation on the skin are not smooth, and the heat in the human body cannot be spread out in time, which will make people feel even worse. According to the calculation of somatosensory temperature, it is found that when the temperature reaches a certain height, the higher the humidity, the higher the somatosensory temperature under the same temperature condition. Moreover, the sultry "sauna day" is easy to make people unable to dissipate heat in time, leading to an increase in body temperature and a rapid heartbeat. If the body temperature rises to the limit, it will be life-threatening. ② In sauna days, these organs are vulnerable! 1. Heart summer is a period of high incidence of cardiovascular diseases, especially the sultry "sauna days". In an interview with Health Times in 2013, Yun Chunpeng, chief physician of beijing huaxin hospital Cardiology Department, explained that when the humidity in the air increases and the oxygen content decreases, it will easily lead to patients’ lack of oxygen. People who suffer from hypertension and coronary heart disease often feel unwell, with chest tightness, shortness of breath, dizziness and other symptoms, and in severe cases, acute myocardial infarction and cerebral thrombosis occur.2. Lung Cao Naiqing, deputy director of the Department of Allergy in Shandong Provincial Hospital, said in the Health Times in 2011 that the temperature and humidity in sauna days are very suitable for the reproduction and growth of allergens such as fungi and molds. If the air pressure is low in thunderstorm weather, the concentration of allergens floating in the air will increase significantly, and asthma patients will easily increase. ④3. Gastrointestinal tract "Generally speaking, if the temperature reaches 32℃ and the relative humidity of the air is above 80%, not only food and clothes are prone to mildew, but also bacteria and fungi will be very active, which will easily lead to intestinal diseases." In an interview with Health Times in 2006, Wang Guowei, chief physician of internal medicine of Beijing Hospital of Traditional Chinese Medicine, said that fruits, vegetables and grains are moldy quickly in sauna days, and the washed fruits and vegetables fester faster, so they should be eaten and washed now. ⑤4. Nasal cavity Zhang Jianzhong, director of dermatology department of Peking University People’s Hospital, said in an interview with Health Times in 2011 that people naturally prefer to hide in air-conditioned rooms for the summer in hot and humid sauna days. Many people sneeze frequently when staying in an air-conditioned room for a long time, which is caused by the stimulation of cold air. The cold wind will also drive the dust on the air conditioning filter to stir up, causing people to get sick after inhaling these allergens, causing the onset of allergic rhinitis. ⑥5. Skin sauna days will weaken the resistance of the skin and easily induce skin diseases. The most common are skin itching, tinea, eczema, fungal infection and dermatitis caused by sunlight. In addition, many people like swimming in summer, and they may be infected with skin diseases. Therefore, people must pay attention to it.6. Wang Yue, director of the Department of Obstetrics and Gynecology of Henan Provincial People’s Hospital, said in an interview with Health Times in 2016 that in hot and humid weather, bacteria are easy to breed. If you don’t pay attention to hygiene, women’s private parts will be easily disturbed, especially when women are unwilling to move during menstruation and sanitary napkins are not changed frequently, which will easily provide a hot and humid environment for bacteria, thus causing gynecological inflammation such as fungal vaginitis. ⑦

The preferred dehumidification mode of air conditioning According to the 2018 article of the magazine "Public Electricity" sponsored by Hunan Electric Power Industry Association, in summer, changing the air conditioning mode from "refrigeration" to "dehumidification" can not only make the house as cool as a refrigerator, but also save a lot of money and minimize the harm to the human body. When the dehumidification mode is turned on,The indoor unit will keep running at a low speed, and the outdoor unit will also operate intermittently, so as to keep the room temperature near the set temperature. When the "cooling" mode works, the indoor unit and outdoor unit of the air conditioner will continue to operate until the indoor temperature reaches a low temperature, so it consumes more power. 5.
