While using air conditioners the environment gets very dry. This can cause dehydration in the body that cannot be replenished by drinking water.
Spending large amounts of time in an air-conditioned environment can make a person lethargic. Cool temperature lowers the body’s metabolic rate which may lead to an overall feeling of fatigue.
People with a history of respiratory issues can experience severe discomfort in an air-conditioned environment. The cool dry air may irritate the throat and cause coughing and sneezing.
Headache can result from the abrupt temperature shifts between the warm outdoor air and the cool indoor air. This can cause blood vessels in the brain to abruptly contract and expand. Prolonged exposure to cold, dry air can also trigger migraine and sinusitis.
