General weakness after blowing air conditioner is usually called air conditioning disease, also known as air conditioning syndrome. This disease is more frequent in summer, because pathogenic microorganisms breed in the room of air conditioning, room confinement is too strong, often open air conditioning and relatively poor air circulation, small air volume, long open air conditioning without opening windows, sunlight exposure is not sufficient, pathogenic microorganisms are easy to breed. The sealed pipes and blowers in air conditioners also create a good breeding space and breeding environment for the survival of pathogenic microorganisms, which can lead to infections in the upper respiratory tract and the perimeter of the body, and again susceptible to respiratory, digestive, neurological and endocrine multi-system diseases. Therefore, a series of clinical symptoms such as weakness, aches and pains, dizziness, headache, loss of appetite, and joint pains can occur.
