Does air conditioning have radiation? What diseases are easy to get by blowing air conditioning for a long time
Sihai network: when summer comes, air conditioning has become an indispensable tool in our daily life. Many pregnant women are afraid to turn on the air conditioner because they are worried about the radiation from the air conditioner. Is there any radiation from turning on the air conditioner? What diseases do you get from blowing the air conditioner for a long time in summer?

Does the air conditioner have radiation
1. Theoretically, as long as the electrified objects are radiated, it's just a matter of strength. The radiation of air conditioner is very small, and there is no harm to human body.
2. Radiation refers to the phenomenon that part of the electromagnetic energy from the field source propagates away from the field source and then returns to the field source. The energy diffuses outward in the form of electromagnetic waves or particles (such as alpha particles, beta particles, etc.). All objects in nature, as long as the temperature is above the absolute temperature zero, transmit heat to the outside constantly in the form of electromagnetic waves and particles, which is called radiation. The radiated energy radiates in a straight line from the radiation source in all directions. The energy released by an object through radiation is called radiant energy. Radiation is calculated as roentgen / hour (R). Radiation has an important feature that it is' equivalent '. No matter the temperature of the object (gas) is high or low, it radiates to B, and B radiates to a. The term is generally used in ionizing radiation. Radiation itself is a neutral word, but radiation from certain substances may cause harm.
3. Air conditioner is also called air conditioner. It refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building / structure by manual means. Generally, it includes cold source / heat source equipment, cold and hot medium transmission and distribution system, terminal device and other auxiliary equipment. It mainly includes water pump, fan and pipeline system. The terminal device is responsible for using the heat and cold from the transmission and distribution, specifically dealing with the air to make the air parameters of the target environment meet the requirements.
What diseases are easy to get by blowing air conditioner for a long time
rhinallergosis
As soon as some people enter the air-conditioned room, they will have symptoms such as nasal congestion and runny nose. Taking cold medicine will not work. It may be allergic rhinitis. The reason is that the air-conditioner will stimulate the peripheral nerves in the nasal cavity, resulting in the rapid contraction of the nasal mucosa, the increase of gland secretion, and then the rhinitis symptoms such as runny nose and sneezing. In addition, some people are allergic to dust and dust mites blown out by the air conditioner, thus inducing allergic rhinitis.

Dysmenorrhea and menstrual disorder
Generally in public places or business office buildings, there are many people in and out, and the air temperature is generally low. In summer, women often wear short skirts and sandals to go to work. In this way, long-term cold stimulation may affect ovarian function, cause ovulation disorders, and lead to menstrual disorders. Or suddenly from the hot outdoor into the low temperature indoor, so that the body temperature difference is too large, the peripheral blood vessels can not contract quickly, resulting in poor peripheral blood circulation, in the long run, abdominal pain and dysmenorrhea are easy to occur.
Upper respiratory diseases
The respiratory tract is also very fragile under the effect of air conditioning. Once the air conditioner breaks through the fragile 'defense line' of the respiratory tract, the symptoms of coughing, sneezing, runny nose and other colds will appear, i.e. upper respiratory tract diseases, and the severe ones will cause pneumonia and other serious lower respiratory diseases. If it is not treated in time, it will be life-threatening.
Knee joint disease
Long term in the air-conditioned room is also easy to cause 'air conditioning legs'. Because when the legs and knees are exposed to low temperature for a long time, the vasoconstriction of the legs will be affected, which will induce knee joint diseases such as synovitis and bursitis.

Cervical spondylopathy
Cervical spondylosis has a lot to do with cold. In summer, in the office, especially when the seat is facing the air conditioner, the muscles of the back of the neck are easy to suffer from cold. Over a long period of time, it is easy to cause muscle spasm, pain, vasoconstriction, blood circulation disorder, and induce or aggravate cervical spondylosis.
Infantile asthma
In hot summer, the excessive temperature difference between indoor and outdoor will make the babies with low immunity suddenly attacked by cold air, which will cause bronchoreflex spasm, cough and asthma. If the air conditioner is not cleaned in time, the dust and mites in the air conditioner will easily lead to children's coughing and even induce asthma.
