In recent years, the summer weather is particularly hot, and many cities across the country still continue to be above 38 ℃ after the autumn, air conditioning has become the protector of people from the heat. The air conditioner is effective in creating an external environment for the human body, bringing people comfort and coziness, but it also disrupts people’s ability to adapt to the environment, and “air conditioning disease” occurs. The human body is a sophisticated organism, which naturally has the ability to adapt to external stimuli with rapid response to the conditioned reflexes. After cold stimulation, the thermoregulatory center can regulate the skin, sweat glands, blood vessels and muscles through peripheral nerve reflex arcs to cause contraction or expansion, thus maintaining a constant body temperature and improving the body’s ability to adapt to external stimuli. The air-conditioned environment is equivalent to the artificial cooling process, which makes people instantly enter an ambient temperature with a large difference from the outside world, so that the original normal adaptation function is disrupted, and the organism is adjusted by a large amount in an instant, if the intensity of the contrast is disparate, or frequently repeated, especially at night when resting, with the air conditioner on all night, and with very little clothing, the midnight yin gradually grows, living in such an environment, it is very easy to catch cold, resulting in dizziness, headache, headache, and coldness. This leads to dizziness, headache, nasal congestion, drowsiness and fatigue, irritability, dry throat, gastrointestinal discomfort, waist, back and joint pain, menstrual disorders, dysmenorrhea and other symptoms. Thus, the immunity of the body is affected, leading to heat stroke, colds, fever and other common air conditioning syndrome (air conditioning disease). After a long period of observation, people realize that long-term in the environment with air conditioning, cold, fasciitis, arthritis, resulting in stiff joints, flexion and extension of unfavorable, muscle pain. Although “air conditioning disease” is not a major disease, but once people suffer from this disease, after all, to affect the normal work and life. Therefore, in the air conditioning to prevent heat, you can use the following methods to prevent air conditioning disease: 1, so that the indoor air is fresh, keep the circulation. Constantly update the air is the fundamental measure to prevent air conditioning disease. The best installation with a new air conditioner, can make the indoor air and fresh outdoor air constantly exchange. Do not open the air conditioner without a new fan continuous doors and windows closed, at least 3 to 4 hours to maintain regular ventilation to ensure that the air has sufficient fresh oxygen content. 2, reasonable adjustment of indoor temperature difference. China’s general summer comfortable indoor temperature of 26 ~ 29 ℃, relative humidity 40 ~ 60%, indoor and outdoor temperature difference to not more than 5 ~ 8 degrees is appropriate. 3, keep warm. Whether it is the desk or the bed in the living room, should be away from the air conditioner. The closer the air conditioner, the faster the flow of cold air, the greater the impact. People who work in air-conditioned rooms for a long time should add some clothes that are easy to put on and take off, and the knees should be covered with bath towels, knee pads and other warm items. In addition, you should stand up and move around for a while to increase the circulation of peripheral blood. The frail, the elderly, children who do not have a good sense of temperature difference, and those who have poor temperature regulation in vitro, especially need attention. 4, when sweating should not immediately enter the refrigeration air conditioning room. Therefore, the pores are expanding, immediately after the cold contraction leads to traumatic wind and cold invasion caused by disease. People who have the conditions, after returning home from work should first take a bath, the water pressure is adjusted higher, you can make a full-body hydro massage. Or after the shower in bed on their own massage, or use the massager to restore the body’s blood circulation. 5, the air conditioning exhaust hole is unclean air must pass through, should not stay at the blowing mouth for a long time. Air-conditioning use, the room air suspended floating dust increases, causing respiratory diseases, especially the use of carpeted rooms often have mites, so it is best to configure air purifiers. Smoking is strictly prohibited, keep the room clean, and use a wet cloth to wipe dust cleaning to improve indoor air quality. 6, air conditioning filter after a long time, indoor cactus can be placed to play a role in supporting air purification. You can also often “vinegar” fumigation of air-conditioned rooms. In the heat of the season, people use “air conditioning” to prevent heat, but also do not have to leave the air conditioning. You can avoid the strong sunlight, do some outdoor soothing exercise, which is more conducive to health.
