1. What are the consequences of closing the door while using the air conditioner?
Many air conditioning experts have provided information that indoor air in closed rooms is at 2 to 5 times higher risk of bacterial contamination compared to outdoor air.

Many Vietnamese families have a habit of closing the door when using the air conditioner to optimize electricity usage. This practice makes the room more stuffy, causing oxygen deficiency and breathing difficulties due to the confined space. This especially affects children and the elderly, posing health risks.
2. Guidelines for effective and energy-saving air conditioner usage
Keep the room door open to allow air circulation
Closing the room door helps limit the loss of cold air. However, you should not keep the room door closed for too long as it can be harmful to your health.

According to experts, every 30 minutes, you should open the room door to allow air circulation. This measure helps refresh the air in the room, preventing stuffiness and its negative effects on the health and well-being of occupants.
Install a ventilation fan
You should install a ventilation fan in the room to assist in air circulation, preventing oxygen deficiency and stuffiness, especially when using the air conditioner.
When using the air conditioner, let the ventilation fan operate as well. This allows for better air circulation, minimizing negative health impacts on family members.
Use an air conditioner with air purification function

If your family is financially capable, prioritize choosing an air conditioner equipped with air filtration and disinfection functions in enclosed spaces. This feature is crucial, especially for families with children and the elderly.
Avoid sitting in a room with the air conditioner on for too long.
Sitting in a closed room with the air conditioner constantly on for prolonged periods can negatively affect the health of the occupants.
You should not stay in an air-conditioned room for more than 4 hours except at night when sleeping requires air conditioning. This can make your body dependent on the air conditioner's temperature, affecting your ability to adapt to the ambient temperature outside. Therefore, take a break every 2 to 3 hours to adjust the temperature.
