Dry Skin And Dehydration

Excessive time spent in air-conditioned places may deprive your skin of moisture. The humidity is kept minimal by the continually moving cool and dry air and your skin might be tight, flaky and dehydrated. This may also overtime leave your lips chapped and your eyes dry, particularly when you are not taking enough water.

Persistent contact with AC may occasionally cause breathing troubles. There is a possibility of dust, allergens, and bacteria accumulation in poorly maintained air conditioners, which are then spread to the air. This can cause the onset of symptoms such as sneezing, sore throat, nasal congestion or even exacerbate other conditions such as asthma and allergies in sensitive individuals.  Also Read - World Thalassemia Day 2026: Expert explains why couple screening before pregnancy can help prevent inherited blood disorders
