conditioned any harm to human health? Air conditioning the disadvantages: the long-term air-conditioned room can cause sweat glands shut down, affecting the normal metabolism and secretion; while long sit without movement would cause imbalance neck movement, neck muscle, nerve, spinal cord, vascular involvement, as time passes will lead to localized cervical spondylosis, ranging from stiff neck, stiff, pain, shoulder and back heavy, upper limb weakness, numbness of the fingers, while headache, dizziness, vision loss, nausea, abnormal sensation, or even urine out of control. Also note that improving fixed sitting in air-conditioned rooms. Work, watching television about 1 hour should be a change of position, or for a short neck flexion, extension, and rotation around nature, neck to improve blood circulation, relieve neck muscle fatigue. Long desk people should pay attention to the case of Taiwan commensurate with the height of the seat, to avoid excessive neck flexion down, the best use activities Banpo type ramp desk. Once cool air to break up the respiratory tract fragile "defense", ranging from cough, sneezing, runny nose and other cold symptoms, namely on respiratory diseases. This is often said that cold hot cold, partly because often in and out of air-conditioned room, the body can not adapt Enthusiasm temperature; the second is due to the air-conditioned rooms are closed, more people have the room with poor air circulation, if a person appears cold symptoms, will soon infect others. Air conditioning cause more serious lower respiratory tract disease, pneumonia. Especially in the central air-conditioning work, the study, central air conditioning is suitable for Legionella transmission, incubation period is about 2 to 12 days, although there is no upper respiratory tract reactions, but fever, chills, muscle aches, dry cough, no sputum or less sputum If not treated in time will continue to have a fever, dry cough, chills. In addition, although the room cool, but the humidity is too low, which people eyes, nasal mucosa were negative. And dry environment suitable for the survival of the bacteria and viruses, people feel the nose, dry throat when we should be especially careful the virus to invade. Frequent air-conditioned room, there must be a transition temperature, for example, put up or turn off the air-conditioning temperature, when the door must first drop of sweat dry.

According Zhuren introduction, this is a common brain disease caused by the air conditioner imbalance reaction. Anion air contains can inhibit the central nervous system, relieve brain fatigue. However, the air conditioning was too adsorbed anionic, cationic make the house more and more, anion and cation disorder also allow people to follow the brain system disorders imbalance. Try to avoid prolonged stay in air-conditioned room, if the best conditions at a constant temperature of about 24 ℃, indoor and outdoor temperature difference Chaoguo 7 ℃, but also regular window ventilation to ensure indoor and outdoor air convection, start 1-3 the best hour period off air conditioning, open windows for fresh air, natural cold air is the best. If conditions do not permit, their best every hour to the outside corridor with windows for ventilation place, especially for a lunch time outdoors, most importantly, do not because of the heat on the air conditioning blowing BARS.
