cause of a disease
1. The main cause of air conditioning disease is dry air, and most of the skin is exposed to this dry air and loses a lot of water; When breathing, inhaling dry air and exhaling saturated moisture will dry the nasal mucosa and tracheal mucosa, and when it is serious, it will crack, and viruses such as colds will take advantage of it and cause colds and coughs.
2. The room is closed, the air mobility is poor, the air volume is small, the window is not opened for a long time, and the sunshine is insufficient, which is easy to breed pathogenic microorganisms.
3. the temperature difference between indoor and outdoor is large, and the body is not suitable. The autonomic nervous system of human body is difficult to adapt, which will cause the disorder of biological rhythm and autonomic nervous function. With the development of society, most people will use air conditioning in summer, but how many people know that being in an air-conditioned environment for a long time will cause air-conditioning diseases. Speaking of air-conditioning diseases, some people may not know what air-conditioning diseases are. Symptoms of air conditioning include fever such as cold, fatigue, dizziness, headache and skin allergy. Once your body sends these signals, you should go to the hospital for treatment in time.
Therefore, in air-conditioned rooms, due to dry air, there are symptoms of "air conditioning disease" such as stuffy nose, dry eyes, dry mouth, dizziness, sneezing, tinnitus, fatigue, memory loss, tight and dry skin, allergy, wrinkling, joint pain and muscle pain, all of which are dehydration of human tissues, affecting the normal operation of tissue nutrients and waste.
In addition, dry air will shrink, harden, crack or even damage textiles, carpets, paper, leather, plastics and wood that constitutes furniture. Air drying will also cause a lot of dust, and various viruses, bacterial spores, various microbial eggs, etc. will spread in these dust and diffuse indoors, which is easy to cause infection.
In fact, proper humidity is as important to the owner of the room as temperature. In general, the optimum relative humidity for human body to feel comfortable is 40% ~ 70%. Too low or too high relative humidity is uncomfortable and even harmful to human body. When people are outdoors, they sweat and dissipate heat due to the large amount of activities, which consumes a lot of energy. At this time, the air humidity is 40% ~ 50%, which makes them feel most comfortable. In the office, due to the small amount of human activity, the air humidity is the most comfortable when it is 50% ~ 60%; When sleeping in the bedroom, because the function of human tissues is in a semi-stagnant state, the human body is in a relaxed state and consumes the lowest energy. At this time, the air humidity is 60% ~ 70%, and it feels most comfortable.
General air conditioning disease will be accompanied by the following symptoms:
1, headache
Air conditioning is still very harmful to the brain. When we stay outdoors for a period of time in hot summer, the body temperature is extremely high, and then immediately get into the air-conditioned room, the skin temperature will turn from hot to cold, especially when the temperature difference between indoor and outdoor reaches more than 5 degrees Celsius, the blood vessels will expand with heat and contract with cold, and then there will be symptoms of headache.
Step 2 catch a cold
We often hear some advertising words "alternating hot and cold, beware of catching a cold". This advertisement is not just talk. When we enter the cool air-conditioned room from the hot outdoor, the respiratory tract is easily stimulated, and we will definitely sweat outdoors. Once we enter the air-conditioned room, the capillaries will suddenly contract sharply when they are cold. On the contrary, if you stay in an air-conditioned room for a long time, your pores will shrink. Once you enter the sultry outdoor, your pores will not open in time and you will catch a cold.
Joint pain
It is expected that the direct blowing of cold air and the temperature difference between indoor and outdoor will cause the disorder of joint synovial fluid secretion in air-conditioned rooms, and then induce pain in knee joints, bare joints, elbow joints and even neck and waist, especially in the elderly.
4. Dry skin
Dry skin is the most common, especially people with chronic skin diseases, who are quite sensitive to temperature changes. In addition, it is easy to lack water in an air-conditioned room for a long time. If water is not replenished in time, it is easy to cause dehydration.
5. Eye interference
There is a filter screen at the cold air outlet of the air conditioner, so we usually don't pay attention to cleaning it. For people who wear contact lenses and suffer from chronic conjunctivitis and dry eye, accelerating eye intervention will increase the probability of recurrence.
Pitaya is rich in nutrition, containing plant albumin, anthocyanins, vitamins, water-soluble dietary fiber, etc., which are rare in general plants. Regular consumption can clear away heat and toxic materials and relieve patients' discomfort. Every100g of kiwifruit contains 300 mg of vitamins, which is 20 times that of apples. In addition, it also contains a variety of amino acids and anticancer substances necessary for human body, which has the functions of protecting the heart and enhancing physical fitness. Bananas contain substances that can increase the content of 5- hydroxytryptamine in the brain, which can alleviate the irritability caused by summer!
Common cactus, chlorophytum and Phyllostachys pubescens are the best choices for indoor cultivation of green plants.
Cactus can breathe out oxygen at night to make the air moist and mild; Chlorophytum will evaporate the moisture of leaves and increase the indoor humidity; Ornamental green plants such as Fu Guizhu have also been well disinfected.
The hot air discharged from the air conditioner is warm and dry. People have been in this environment for a long time. Not only do they have dry skin, dry eyes and dry lips. Seriously, they can tear off dry skin. Others get angry, catch a cold, have a runny nose, have a sore throat and have inflammation of the trachea. These situations occur because the external factors of air conditioning and heating make people feel warm, but they also cause the imbalance of human health and produce the above discomfort.
These discomforts not only delay the work progress, but also make the body and mind suffer. Many people will ask, besides drinking more water, what else can be done to alleviate it?
Autumn and winter conditioning is mainly based on "moistening", and honey has the effects of nourishing, moistening dryness, moistening skin and moistening lungs, so drinking honey is the best choice to deal with the dry season in autumn and winter.
Function. It should be reminded that there should not be too many indoor plants to avoid the increase of indoor carbon dioxide content when breathing strongly at night, which will lead to the decline of air quality. In addition, attention should be paid to watering indoor green plants in time.
Stay in a closed room for a long time in winter, and toxic and harmful gases cannot be discharged in time. After they enter the human body, the human body will inevitably feel dizzy and uncomfortable. There are still many people who like to adjust the temperature to the highest, which leads to a great temperature difference between indoor and outdoor. When people suddenly enter the "high fever" or "low cold" environment, it is easy to catch a cold.
An obvious symptom of air conditioning disease in winter is dry skin. One of the reasons for dry skin is that the indoor air humidity is too low, which makes the skin in a state of water shortage. Another reason is that the air conditioning temperature is too high, which takes away a lot of water from the skin. If you want to use air conditioner for heating, you'd better adjust the air conditioner temperature to 16~26, and the optimal temperature is 20. Need to be reminded that the indoor temperature should not be overheated, and the indoor and outdoor temperature difference should be less than 6 as far as possible, which is not only beneficial to health, but also can avoid the overload operation of air conditioners. At the same time, pay attention to replenish water to the body or use a humidifier to increase air humidity.
