Can aircon make you sick?
Does the air conditioner in a office make one sick? Flu? Colds? Sinus conditions?
It's possible for infectious diseases like colds and flu to be spread by air conditioning units, but it's probably rare. You're more likely to catch a cold by touching a contaminated surface and then touching your face. Simply working in an office means you'll come into contact with a lot of people and a lot more germs than at home. (Scold anyone who drags themselves to work when they’re sick!)
