Air conditioning controls humidity levels in the air. As all of us know, a humid atmosphere is a breeding ground for the moulds, mites and dust which cause allergies. Air conditioners can control humidity level from 40 to 60% meaning those hot temperatures can be controlled reducing areas for moulds to develop. This prevents people suffering from different allergies.
Another big benefit is of course ventilation which does help health. Mechanical ventilation is becoming vital for health because of changing construction technology. The main purpose of air conditioners is producing fresh air which creates an environment less prone to sickness.
Only thinking about ventilation is very narrow minded and not enough. You must also make sure that the air which you breathe is clean. Many proven brands such as Daikin air conditioning and Toshiba air conditioning units are provided with an air filter. There are different types of filters used on various types of air conditioning systems. The main job of filters is cut down dust particles as well as bacteria. You will even see smoke and microbes filtered. All this makes the air a lot cleaner for breathing. However, if you do not clean the filter regularly or replace it from time to time, you will only be risking attacks from bacteria and other pollutants.
It is wrong to say that if you use air conditioning you will feel sick. This kind of thinking it just not true and if you do research on the subject you will see that research has proven this. If maintained it only provide clean air and ventilation to your room.
