The cause of "air conditioning disease"

The air conditioner and the cold air produced itself are not harmful. The air -conditioning dehumidification function can help dry houses, but it cannot solve the moldy or messy wall and floor. If your home or office is often not ventilated or clean enough, unfortunately becomes the breeding place of mold and bacteria, then the air conditioner will promote the pyramids and allergens that are likely to induce disease, such as pollen, pesticides and other outdoor pollutants in the air. , Resulting in nasal congestion, sore throat, and even difficulty in breathing.

If the maintenance is improper, the air conditioner itself will become a breeding room for molds and bacteria. When the air passes through the coil of the air conditioner, it will produce condensation. If it is not cleaned from time to time, condensate can create an ideal environment for the growth of bacteria and mold. Dirty filters, unclean pipeline systems and ventilation ports and bad overall maintenance will cause the air -conditioning system to release mold and other pollutants into the air of our daily breathing.

Of course, the air conditioner is too cold to cause "air conditioning disease". First of all, the virus that causes a cold will spread, and some viruses exist in the low humidity and cold environment when the air conditioner temperature is too low. Second, ultra -low temperature will also cause skin capillary to contract to protect the body from the loss of heat loss, but this is this Reduced blood flow, including white blood cells that protect the body for virus infringement, but make the body susceptible to illness. Finally, the ultra -dry environment evaporates the moisture in the nasal cavity, and the wetness of the nose weakens the opportunity to be infected.

Some people turn on the air conditioner all day at home, or sweat into the house from the outside, and suddenly adjust the temperature very low, and even run to the air conditioner directly. ° C, the cold air that comes from the skin can easily stimulate the capillaries of the surface of the surface, which causes discomfort such as headache, dizziness, and even panic.

Misunderstanding 3: Many people do not pay attention to the harm caused by long -term air conditioning, and feel that they have a cold, dizziness and headache, especially those who are young and strong.

Cold air damage the joints very much. If you do not pay attention to keep warm for a long time, it is easy to suffer from arthritis after the old age, and it will be difficult to treat it.
