How do air conditioners impact human health? Can they cause diseases? These questions concern many people because only air conditioners can save people from the heat in Yerevan, as well as in many other cities.

Based on a study released in the International Journal of Epidemiology in 2004, office workers sitting in rooms with air conditioners get sick more often.

Professor Farah Shroff from the University of British Columbia claims that air conditioners have positive and negative sides. They protect us from the scorching heat that can be very dangerous for people with cardiovascular diseases and those who suffer from other diseases and can also protect one from polluted air, if they are filtered the right way. However, if the air conditioner is not checked the right way, it can pose a risk. If there is water in it, bacteria might grow and appear in the air, infecting people with a weak immune system.
