Lucknow: A dry throat, cough, or irritation during summer may not always indicate an infection. Prolonged exposure to air-conditioned environments can trigger these issues, doctors told TOI, noting a rise in such cases over the past week.
Rising Cases Linked to AC Use
Approximately 10 to 15 patients visit hospitals daily with these symptoms. Many attribute them to a "summer cold," but medical experts point to extended use of air conditioners set at low temperatures as the primary cause. Air conditioners reduce moisture in the air, leading to dryness in the nose and throat, which causes irritation.
Expert Insights
Prof. Rajendra Prasad, former head of pulmonary medicine at King George's Medical University (KGMU), explained that cases increase with summer heat. "Dry air irritates the breathing passages. Many think it is an infection, but it is usually due to AC use," he said.
Doctors emphasize that symptoms differ from viral infections. Patients typically experience a dry or scratchy throat and a mild cough, without fever or body ache. Viral infections often present with fever, fatigue, and a runny nose.
Preventive Measures
Prof. Santosh Kumar from KGMU advised maintaining the AC temperature between 24 and 26 degrees Celsius to reduce dryness. Direct cold air and prolonged stays in closed rooms can worsen symptoms, particularly in children, the elderly, and individuals with asthma or allergies.
Prof. Ajay Verma, head of respiratory medicine at Ram Manohar Lohia Institute of Medical Sciences, warned that continuous exposure increases sensitivity. "In people with asthma or allergies, it can trigger breathing problems. Avoid direct airflow and take breaks," he said.
Maintenance Matters
Doctors also highlighted the importance of proper AC maintenance. "Unclean filters spread dust and allergens," Prof. Verma noted. Experts recommend keeping the AC at a moderate temperature, ensuring proper ventilation, drinking adequate water, and cleaning filters regularly.
