Blow the air conditioner too much and you may get air conditioning sickness! ! !
Symptoms of air conditioning vary from person to person:
respiratory diseases
When entering the air-conditioned room from the hot outdoor, the respiratory tract is most easily stimulated. Once the cold air breaks through the fragile "defense line" of the respiratory tract, there will be upper respiratory diseases such as cough and runny nose. Looking forward to staying in an air-conditioned room for a long time, the pores suddenly contracted and came to a stuffy room or outdoors, and the pores could not be opened in time. If the body's regulating center is improper, heatstroke or sore throat will occur. In addition, the humidity of air conditioning environment is too low, and the dry environment is suitable for the survival of germs and viruses, which increases the chance of illness. For example, central air conditioning is very suitable for the spread of Legionella, and the incubation period is about 2- 12 days.
arthrosis
Head bowed for a long time at work, and the muscles of the neck and back are in a state of tension for a long time, which easily leads to cervical strain. In hot weather, some people are used to letting cold air blow on the back or neck, and the evil of wind-cold takes advantage of it, which can easily lead to muscle spasm and nerve edema in the neck, thus leading to neck and shoulder pain and causing or aggravating cervical spondylosis. At the same time, because the low temperature environment will stimulate the rapid contraction of blood vessels and poor blood circulation, it will lead to joint injury and cold pain, such as stiff neck and back, sore waist and legs, cold and numbness of hands and feet.
Cranial neuropathy
Air conditioning is also very harmful to the brain. After working outdoors, people rush into the air-conditioned room, and the skin feels that the temperature difference is too large, and the blood vessels contract rapidly from the expanded state, thus causing headaches, and even serious mouth-eye deviation. The reason is that after catching cold, the vascular nerve function of local tissues in the ear is disordered, causing facial nerve ischemia. The negative ions in the air can relieve brain fatigue, while the air conditioner absorbs too many negative ions, which leads to the imbalance of negative ions and positive ions, leading to the disorder and imbalance of the brain nervous system, and symptoms such as "dizziness, chest tightness, palpitation, weakness and forgetfulness" appear. In addition, in the air-conditioned closed environment, the concentration of carbon dioxide rises and the air is dirty. After a long time, the brain will be deprived of oxygen, and symptoms such as dizziness, fever, night sweats and physical weakness will appear.
Gastrointestinal diseases
If the room is too "cold", the sympathetic nerve will be excited, which will lead to the contraction of abdominal blood vessels and the weakening of gastrointestinal movement. In addition, people often eat cold drinks in summer, and both inside and outside the intestine are controlled by "cold", resulting in many corresponding symptoms. It's not surprising that many people pull and vomit.
dermatitis
Staying in an air-conditioned room for too long often makes your skin dry and itchy. It turns out that a lot of dust, mold and so on have been adsorbed on many air conditioning filter elements. As the cold air of the air conditioner blows into the room, it adheres to the human skin or is inhaled into the body. In addition, in the closed environment of air conditioning, indoor dust and dust mites cannot circulate, which greatly increases the probability of inducing dermatitis such as eczema. In addition, the air in the air-conditioned room is dry, but we wear less clothes and most of our skin is bare, which accelerates the loss of water and becomes another main reason for eczema recurrence. In addition, some people's skin has poor cold-proof function. When the skin is suddenly stimulated by cold wind, the mast cells of local skin will release histamine substances, which will make the small blood vessels of the skin dilate and hyperemia, enhance the permeability of blood vessels, make the skin appear wheal and local edema, and cause cold urticaria.
Gynecological diseases
Cold evil has a great influence on women. Being in a cold air-conditioned environment for a long time, blood will coagulate when it is cold, and cold will cause blood vessels to contract, blood will stagnate, and the formation or elimination of menstrual blood will be blocked, causing dysmenorrhea. At the same time, cold stimulation can also affect ovarian function, ovulation is hindered, manifested as menstrual disorder.
Ocular lesion
The dryness of air-conditioned rooms also affects the eyes. People who wear contact lenses for a long time and suffer from chronic conjunctivitis or dry eye are prone to dry eye and have a high recurrence rate. If the filter screen at the outlet of the cold air is not cleaned, the situation will be even worse. In the closed office building, the air conditioning system keeps circulating, and high-concentration carbon dioxide keeps accumulating in the air. Eyes staring at the computer screen for a long time in the absence of oxygen are prone to redness and itching.
What is the cause of air conditioning disease-doctor's analysis;
On the one hand, low room temperature will make the blood vessels, sweat glands and sebaceous glands of human skin contract, the nerve regulation will be disordered, and the human body's resistance will decrease;
Second, the air conditioner is not cleaned in time, which is easy to breed bacteria such as Legionella and increase the chance of human illness;
The third is that the temperature difference between indoor and outdoor is too large, so it is difficult for the human body to quickly adjust from hot outdoor to cool indoor, resulting in a series of uncomfortable reactions; Not only that, being in an air-conditioned closed environment for a long time, the concentration of carbon dioxide rises, the air is dirty, and it is easy to cause diseases.
preventive
◆ 1. When using air conditioner, be sure to pay attention to ventilation. Open the window regularly every day, turn off the air conditioner, and add air for ventilation to keep a certain amount of fresh air indoors. It is best to clean the air conditioner once every two weeks.
◆2. When going out in an air-conditioned environment, you should first move in the shade for a while, and then move in the sun after your body adapts; If you are in an air-conditioned room for a long time, you should go outdoors more and drink more boiled water to speed up your metabolism.
◆3. The room temperature and outdoor natural temperature of the air conditioner should not be too high, and should not exceed 5 degrees. It is best not to use air conditioning at night. It is safer to turn off the air conditioner when you are asleep. Being outdoors before going to bed is conducive to promoting blood circulation and preventing air-conditioning diseases.
◆4. When working and studying in an air-conditioned environment, don't let the cold air from the air outlet blow directly on your body. It is best not to blow air conditioning directly when sweating, so the temperature drops too fast and it is easy to get sick.
◆5. Smoking is prohibited indoors.
◆6. Always keep your skin clean and hygienic. This is due to frequent contact with air-conditioned environment, sudden changes in heat and cold, and bacteria attached to the skin are easily blocked in sweat glands or sebaceous glands, causing infection and suppuration. Therefore, always take a bath and keep your skin clean.
◆7. Use disinfectants to kill and prevent the growth of microorganisms.
◆8. Add a dehumidifier to prevent bacterial growth.
◆9. Don't turn on the air conditioner in the stationary car, so as to prevent the carbon monoxide discharged from the automobile engine from flowing back into the car and causing an accident, that is, carbon monoxide poisoning.
◆ 10. Pay attention to the clothes in the workplace to meet the requirements of keeping warm in an air-conditioned environment.
◆ 1 1 Generally speaking, the better room temperature is 27℃-28℃. Men can lower 1℃-2℃ appropriately. Of course, this value is not absolute, because when the outdoor temperature is very high, the temperature difference between indoor and outdoor will exceed the adjustment range of human body. [ 1]
The prevention of air-conditioning diseases is mainly the above ten items. If you have symptoms such as cold, fever, pneumonia, mouth and eyes askew, you should consult a doctor in time.
Chinese medicine health experts suggest that you should pay attention to the following points when blowing air conditioners frequently:
1, it is said that it is absolutely true to eat radish in winter and ginger in summer. Proper consumption of ginger in summer can make people sweat, promote systemic blood circulation and ensure smooth blood supply.
2. Vinegar can be regarded as the first choice for air conditioning, because it can increase the concentration of gastric acid, increase appetite, promote the secretion of digestive juice, inhibit bacteria, and have a good preventive effect on intestinal diseases caused by excessive air conditioning.
3. Eat more tomatoes. The medicinal value of ordinary tomatoes is much higher than that of lovely tomatoes, and they are more nutritious.
4. Watermelon, wax gourd, kelp, mung bean, bitter gourd, etc. It has a good summer effect.
5, drink plenty of water or tea, which can be medicinal tea or green tea, which can promote metabolism.
