are air conditioners bad for health?  

I live in an hot climate and have to use my A/C the majority of the year! It helps keep the humidity levels down and this helps with our allergies. It also helps prevent mold from growing inside the house. Overall I think the A/C is great for us!

The air-conditioners are required to be their because they are more a need than a luxuary in some places where the cliamatic conditions are adverse.

A regular use of air-conditioned use makes you addicted to cool temparatures which becomes a troublsome thing when you have to go working where you don't have this facility.

Frequent going in & going out of air-conditioned cliamet can cause harmful effect on your body health which should be avoided. Atleast you should avoid entering to a/c rooms when you come from a hot sun. or vise versa.

Higher temperatures reduce your working effeciency.
Cool body & cool brain can think better I think.

Wish you all the cool life from oarnamav.
