Can air conditioning make you sick?

Air conditioning is responsible for about 10 per cent of worldwide electricity consumption. With so much exposure to AC, it's hard not to wonder if it has any adverse effects. According to International Journal of Epidemiology, workers in air-conditioned office buildings reported higher rates of illness than those in buildings with natural ventilation. .These symptoms may be due to moisture from AC units. AC units can also collect numerous infectious organisms and allergens. The risk of airborne illness is much lower if the AC units are regularly cleaned and maintained.
