Today's living conditions are getting better and better, and the abundance of material life brings a lot of convenience to our life. However, while we are exempt from heat and cold, new problems are again before us.
'All three of us have a cold and should be contagious.'
With the popularization of air conditioners in the workplace and living rooms, the incidence of air-conditioning diseases is increasing year by year in summer, and the number of patients with respiratory diseases and allergic diseases continues to increase in the summer, most of which are related to air-conditioning diseases. In the air-conditioned room, chest tightness and shortness of breath feeling, which is the so-called air-conditioning disease brought harm.
Some time ago, the weather was very hot, Ms. Chen, a family of three did not sleep well without air conditioning.Since the summer, their home air conditioners are open every day at night the next morning.When sleeping, due to fear of running away air-conditioning waste of electricity , Ms. Chen's doors and windows are generally closed. A few days ago, first Ms. Chen appeared runny nose, throat dry flu symptoms, Ms. Chen ease the purchase of medicine to eat. But then her son also appeared runny nose Cold symptoms, her husband's allergic rhinitis began to commit, not only stuffy nose, cough, but also lead to chest tightness, asthma and other symptoms.Finally, Ms. Chen with children to the hospital for treatment, the doctor told her after understanding the situation, because Their family of three long sleep in airtight air-conditioned rooms, the air is out of circulation, a cold, sneezing or coughing, are likely to cause cross-infection of the virus.
'Older people are more susceptible to air conditioning'
High summer temperatures, poor adaptation of the elderly central thermoregulation can easily lead to flu, fever and other symptoms, may also lead to serious lung infections. Some elderly retired after sleep, housework, playing cards, playing mahjong Of the time is too long, resulting in weakness, decreased resistance, and improper use of air conditioners is also an important cause of the disease. The respiratory tract is the most vulnerable, once the air conditioner breaks through the fragile line of defense of the respiratory tract, ranging from coughing, sneezing, runny nose, etc. Cold symptoms.
In addition, in the air-conditioned room, although it feels cool, but the humidity is too low, which people's eyes, nasal mucosa are negative.While the dry environment for the survival of germs and viruses, people think of the nose, when the throat dry it should be especially careful The virus invaded the same time, the house dust, dust mites circulation can not go out, people with allergies are still very prone to allergic reactions.
Everything in this world are complementary, summer air-conditioning disease, winter does not come a 'heating disease' suitable it?
'Winter indoor heating is open, windows and doors closed causing poor air circulation, dry, can cause decreased immune function and immunity, leading to chest tightness, shortness of breath, restlessness, nasopharyngeal dryness, dizziness, weakness and so on, these symptoms medically Called 'heating sickness'.
Under normal circumstances, the body will evaporate about 1000 ml of water a day, of which 600-700 ml through the skin, through the respiratory tract 300-400 ml. After heating, the indoor Dry, lost water more, for a long time in such an environment, cardiovascular, urinary system will follow 'suffer'.
If the drying time is too long, the respiratory mucosal secretions decreased, dust, bacteria and other attached to the mucous membrane, stimulate the throat to cause cough, easily lead to upper respiratory tract infection, bronchitis, bronchial asthma and other diseases.With the heating, A warm, dry interior is nothing less than a 'hotbed' of germs.
'Older people are still the major group of people with heating problems'
Cardiovascular system to promote blood circulation, heating overheating 'snatching' the body's moisture, will lead to increased blood viscosity, especially for the elderly prone to blood pressure and angina pectoris and other cardiovascular diseases. House heating overheating, and outdoor temperature too Large, may lead to large fluctuations in blood pressure, coronary 'overwhelmed', causing coronary heart disease.At the same time, for patients with cor pulmonale, heart failure, 'fever' can easily lead to symptoms such as palpitation, chest tightness.
Bored! Bored! Bored!
Through!
Important things to say three times !!!
Air conditioning and heating sick, the easiest way is actually timed window ventilation.
However, the problem has come, now the north has become a haze captive, often PM2.5 burst table weather, you dare to open the window?
Faced with such an awkward environment, now only get on the fresh air system: the fresh air system is composed of air supply system and exhaust system of an independent set of air handling system, which is divided into duct-type fresh air system and ductless fresh air system both. Relatively speaking, duct-type fresh air system due to the large amount of engineering more suitable for large-scale industrial area or office use, without duct fresh air system because of ease of installation, more suitable for home use. The main principle is that the air inlet can filter impurities in the air, row Exhaust indoor air can also ensure that the outside world does not enter the dirty air from the room.And the biggest advantage of fresh air system is on the one hand to ensure indoor ventilation, effectively reduce the 'air conditioning' and 'heating sick' probability of occurrence At the same time, air purification is completed at the same time to eliminate haze pollution and ensure fresh and natural indoor air.
