Masterclass prevention "air conditioning sickness," the "weapon"

When you use the air conditioning in the summer heat, different people have different air conditioning does not work with the most common reaction is to lower extremity weakness, headache, dizziness and aching, head of expansion head weight, fatigue, constipation, insomnia, nausea, dry mouth biyang focus, blood pressure, heartbeat, leukopenia, arthritis, laryngitis, susceptible to colds, etc. This can be referred to as "air conditioning syndrome". According to Chinese Academy of preventive medicine, environment and health monitoring of experts, the "air conditioning sickness" abroad there are strict terms and characteristics to be defined, in the domestic people as air-conditioning environment caused by the disease are collectively referred to as "air conditioning sickness." Air conditioning disease occurs mainly in Central closed air conditioning environment, household and air conditioning are also common. This is because in closed or relatively closed air conditioning environment, poor air flow, resulting in indoor air concentrations of oxygen in the decreasing, while the interior building materials, as well as volatile toxic smoke smoke, etc. is difficult to release through air convection to outdoor, led to declining indoor air quality. And since the room closed strong sunlight, the indoor temperature, humidity, particularly suitable for bacteria, survival, and a large number of bacteria, indoor propagation to human health posed a serious threat. People in such an environment, one is susceptible to microbial induced disease; second, the temperature setting is too low, and a large indoor temperature difference, into one easy to catch a cold. Symptoms are easily catch cold, dizziness, breathing does not open. To prevent air conditioning sickness, experts advise users not household air conditioning 24-hour all-weather air conditioner, do not close the window, adjust the temperature and the outdoor temperature difference must not exceed 7 degrees, carpet, bed sheets, sofa cover to regular cleaning. While proper use of air conditioning, its methods are as follows: 1. the regular window ventilation to ensure that indoor and outdoor air convection Exchange, post 1-3 hours after shutdown, and then open the Windows to the indoor air exhaust gases into outdoor fresh. To take advantage of natural wind reducing indoor temperature, it is best to use a negative ion generator. 2. the room temperature should be constant at around 24 ° c, indoor and outdoor temperature difference of not more than 7 ° c, otherwise the sweating in the unit, will increase the burden on thermoregulation hub. 3. use of room air conditioner should be kept clean and reduce sources of disease. 4. indoor air velocity should be maintained at 20 centimeters per second, desk must not direct blowing in the cold, where the air flow will drop 3-4 degrees centigrade. 5. If a long time sitting in the Office, such as typing, writing, wiring, etc., should be appropriate to add easy take off, put on clothes, towels covering the knee protection, bearing in mind the intermittent stand up campaign activities to enhance peripheral blood circulation. 6. home from work, first of all, a warm water bath, massage yourself, such as proper exercise, of course, better. 7. install the air conditioner is to note that on older people and infants should be especially careful because they feel the difference of temperature, thermoregulation is poor, to avoid for the enjoyment of the unnecessary cost.
