5. Asthma and allergies

AC can worsen conditions in people who have asthma or allergies. Among those who are sensitive, staying indoors can help as it keeps them away from other pollutants. But others might actually experience the opposite. If your AC is not properly cleaned and maintained, it can increase risks of triggers which can worsen asthma and allergies.
