Most people tend to keep their doors and windows tightly shut when using air conditioning to prevent the cool air from escaping, believing that it helps keep the room cooler and saves energy. However, this practice can be counterproductive and even detrimental to your health.

The air circulating through an air conditioner can pick up dust and bacteria, as the unit’s exhaust accumulates dust over time. If the room is sealed, these contaminants become trapped inside, and according to Tipsmake, the air quality can be 2 to 5 times worse than outdoor air. Breathing this air over an extended period can be harmful, especially for the elderly and young children, increasing the risk of respiratory issues.

Furthermore, keeping the room sealed increases air pressure, forcing cool air out through cracks or small openings around windows, walls, ceilings, or floors, resulting in energy wastage. The enclosed space can also lead to a lack of fresh air, leaving you feeling suffocated, uncomfortable, and tired.

## So, What’s the Right Way to Manage Doors and Windows When Using Air Conditioning?

It is not advisable to keep the doors and windows closed when the air conditioner is running. The correct approach is to leave them open for the initial 10-15 minutes after turning on the AC. This allows any built-up dust and bacteria to escape, ensuring you don’t breathe in contaminated air.

Additionally, it’s beneficial to open the doors and windows for a few seconds every 15-30 minutes to ventilate the room and promote air circulation. Alternatively, you can create small gaps or use exhaust fans to facilitate air movement, regulate room pressure, and ensure even cooling while reducing energy consumption.

While it’s tempting to stay in an air-conditioned room during hot weather, experts recommend spending no more than 2-3 hours at a stretch in such an environment. Take breaks and step into a regular temperature environment every few hours to maintain your body’s adaptability.
