‘As the temperature soars, patients are often curious to know whether it is safe to spend a lot of time in air-conditioned spaces. Air conditioning is essential for a comfortable lifestyle during the summer.
However, it is important to use it properly to avoid any discomfort. In my medical practice, I have noticed that some patients experience increased discomfort during the summer due to exposure to improperly maintained air-conditioning environments,” says Dr. Pavan Yadav, Clinical Director & Senior Consultant – Interventional Pulmonology & Sleep Medicine, Associate Director – Lung Transplantation, KIMS Hospitals (Krishna Institute of Medical Sciences), Bengaluru.
Dr Yadav shares key insights:
1. Dirty filters can trigger allergies
One of the most common discomforts patients experience is due to dust in the environment. When AC filters are not changed regularly, they accumulate dust. Once the AC is switched on, this dust circulates in the air, which can trigger discomfort or allergic reactions in people who are prone to allergies.
2. People with bronchitis or sinusitis may feel worse
People suffering from chronic bronchitis or sinusitis may experience worsening symptoms in very cold or poorly ventilated air-conditioned environments. Cold, dry air can irritate the airways, causing people with bronchitis to cough more. Similarly, sudden temperature changes and dry air can aggravate sinus congestion, headaches, facial pressure, and nasal blockage in those prone to sinusitis.
3. Extremely cold rooms can irritate the airways
Many people prefer extremely cold AC environments to escape the intense heat outdoors. However, frequently shifting between very cold indoor temperatures and hot outdoor weather can irritate the airways. In my opinion, it is advisable to keep AC temperatures between 24–26°C, which is comfortable for the body.
4. Poor ventilation can affect indoor air quality
Many offices rely on air-conditioning systems that recycle indoor air with minimal fresh air circulation. This can affect indoor air quality and may lead to symptoms such as headaches, dry cough, tiredness, throat irritation, and breathing difficulties. This condition is commonly referred to as “sick building syndrome.”
5. Lack of maintenance can lead to mold growth
One of the biggest concerns I highlight is poor maintenance. Moisture buildup in AC units and ducts can encourage the growth of mold and bacteria. When these contaminants circulate through the air, they may worsen respiratory symptoms, especially in people with asthma or chronic lung diseases.
A Few Simple Precautions Can Help
“I always recommend that patients change AC filters regularly, service their air conditioners periodically, and open windows for some time each day to allow fresh air to circulate. Staying hydrated can also help reduce discomfort,” says Dr. Yadav.
Air conditioners are a necessity during the summer and are indispensable for many people. However, taking a few simple precautions can go a long way in reducing potential health problems.
