Today's living conditions are getting better and better, and the abundance of material life has brought a lot of convenience to our lives. However, while we are free from the heat and the cold winter, new problems are placed in front of us.
"Our family of three have caught a cold and should be infected with each other."
With the popularity of air conditioners in the workplace and living rooms, the incidence of air-conditioning diseases has increased year by year in summer. In summer, the number of patients with respiratory and allergic diseases continues to increase, and most of them are related to “air conditioning diseasesâ€. We often have a feeling of chest tightness and shortness of breath in the air-conditioned room. This is the hazard caused by the so-called air-conditioning disease.
Some time ago, the weather was very hot, and Ms. Chen’s family had no air conditioning and could not sleep well. Since the summer, their air conditioners have been open every night until the next morning. When sleeping, because of the fear of cold air running away from wasted electricity, Ms. Chen’s doors and windows are generally closed. A few days ago, Ms. Chen first experienced symptoms of fluiness and dry throat, and Ms. Chen relieved after she bought the medicine. However, her son also experienced a cold flu symptoms. Her husband's allergic rhinitis also began to commit, not only nasal congestion, cough, but also chest tightness, gasping and other symptoms. Finally, when Ms. Chen took her child to the hospital, the doctor told her after she understood the situation. Because their family had been sleeping in a closed air-conditioned room for a long time, the air was not circulating, and one person had a cold, sneezing or coughing. Causes cross-infection of the virus.
"Older people are more susceptible to air conditioning diseases"
In summer, the temperature is high, and the elderly have poor adaptability to the body temperature regulation center. It is easy to induce symptoms such as colds and high fever, and serious lung infections may occur. Some elderly people can't wait after retirement, and they spend too much time doing housework, playing cards, and playing mahjong, leading to weak body and decreased resistance. The improper use of air conditioners is also an important cause of illness. The respiratory tract is the most vulnerable. Once the cold air breaks through the fragile defense line of the respiratory tract, it may cause symptoms such as coughing, sneezing, and drooling.
In addition, although it feels cool in an air-conditioned room, the humidity is too low, which is detrimental to the mucous membranes of people's eyes and nose. The dry environment is suitable for the survival of germs and viruses. People think that the nose and the scorpion should be especially careful when the hair is dry. At the same time, the dust and dust mites in the house cannot be circulated, and people with allergies are also prone to allergic reactions.
Everything in this world is complementary. There is an air-conditioning disease in the summer. Is it appropriate to have a "heating disease" in winter?
"Winter indoor heating is open, doors and windows are closed, resulting in poor air circulation and dryness, which will cause a decline in immune function and resistance, leading to chest tightness, shortness of breath, irritability, dryness of the nose, dizziness, weakness, etc. These symptoms are medically Called 'heating sickness'.
The biggest cause of "heating sickness" is air drying and loss of body water. Under normal circumstances, the human body will evaporate about 1000 ml of water per day, which is 600-700 ml through the skin and 300-400 ml through the respiratory tract. After heating, the indoors are dry and there is more water lost. In such an environment for a long time, cardiovascular and urinary systems will follow.
If the drying time lasts too long, the respiratory mucosal secretions are reduced, dust, bacteria, etc. adhere to the mucous membrane, irritating the throat to cause cough, prone to cause upper respiratory tract infection, bronchitis, bronchial asthma and other diseases. With heating, the dry and warm interior is no different from a "hotbed" of germs.
“The elderly are still the main population of heating sicknessâ€
The cardiovascular system promotes blood circulation throughout the body. Heating and overheating "grabbing" the body's water will lead to increased blood viscosity, especially for elderly people who are prone to blood pressure and angina. The heating in the house is overheated, and the temperature difference between the outside and the outside is too large, which may cause blood pressure fluctuations, the coronary artery is "overwhelmed", causing coronary heart disease. At the same time, for patients with pulmonary heart disease and cardiac dysfunction, "heating disease" can easily lead to symptoms such as palpitation and chest tightness.
Bored! stuffy! stuffy!
Pass! Pass! Pass!
Important things to say three times!!!
The easiest way to do air conditioning and heating is to open the window and ventilate regularly.
However, the problem has come. Today, the north has become a smoggy captive. It is often the weather of the PM2.5 burst table. Are you sure you open the window?
In the face of such an embarrassing environment, the fresh air system is currently available: the fresh air system is an independent air treatment system consisting of a supply air system and an exhaust air system. It is divided into a ducted fresh air system and a ductless fresh air system. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to the large amount of engineering, and the ductless fresh air system is more suitable for home use because of its convenient installation. The main principle is that the air inlet can directly filter the impurities in the air, and the exhaust port can discharge the indoor air to ensure that the dirty air from the outside will not enter the house from here. The biggest advantage of the fresh air system is that on the one hand, it ensures indoor ventilation and ventilation, which effectively reduces the chances of “air conditioning disease†and “heating diseaseâ€. At the same time, it completes air purification while ventilation, eliminates smog pollution and ensures indoor air. Fresh and natural.
