Medication Efficacy: Some medications are sensitive to temperature and may degrade in high heat. Air conditioning can help ensure the efficacy of these medications.
Preventing Heat-Related Deaths: Air conditioning plays a critical role in preventing heat-related deaths during heatwaves, which have become more frequent due to climate change.

While air conditioning can provide these health benefits, maintaining proper temperature settings, clean filters and adequate ventilation is essential for maximizing these advantages while minimizing potential drawbacks like energy consumption.

What Is Health Risks Of Using Air Conditioner?

While air conditioners offer a lot of benefits, there are also some potential health risks associated with their use, especially if they are not properly maintained or used excessively. Here are some health risks:

Respiratory Issues: Poorly maintained air conditioning systems can become breeding grounds for mold, bacteria and allergens. If these contaminants are circulated into the indoor air, they can exacerbate respiratory conditions such as asthma, allergies and bronchitis.
Dry Skin and Eyes: Air conditioners can reduce indoor humidity levels, leading to dry skin, dry eyes and irritation of the respiratory passages. This is especially concerning in areas with already low humidity.
Respiratory Infections: In some cases, air conditioning systems can spread infections if they are not properly cleaned and maintained. Airborne viruses and bacteria can be recirculated throughout a building, potentially cause to respiratory infections.
Temperature Fluctuations: Frequent transitions between hot outdoor temperatures and cold indoor temperatures due to air conditioning can potentially weaken the immune system and make people more susceptible to illnesses.
Sick Building Syndrome: Inadequate ventilation and poor indoor air quality caused by closed windows and recirculated air can contribute to “sick building syndrome,” where occupants experience symptoms like headaches, fatigue and respiratory issues.
Legionnaires’ Disease: Legionnaires’ disease, a severe form of pneumonia, can be caused by the Legionella bacteria that may thrive in poorly maintained air conditioning systems, especially cooling towers.
Headaches and Fatigue: Spending prolonged periods in heavily air-conditioned environments can lead to discomfort, headaches and fatigue for some people.
Environmental Impact: While not a direct health risk to people, the environmental impact of increased energy consumption associated with air conditioning can have broader health implications due to its contribution to climate change.

These health risks can be mitigated through proper maintenance, regular cleaning and appropriate use of air conditioning systems. Regularly changing filters, maintaining proper humidity levels and ensuring proper ventilation can help minimize these potential risks. If you experience persistent health issues in an air-conditioned environment, it may be worth consulting a healthcare professional or an indoor air quality specialist.

Advices For Healthy Usage Of Air Conditioner

Here are some tips for healthy and efficient usage of air conditioners:

Regular Maintenance: Schedule regular maintenance for your air conditioning system. Clean or replace filters as recommended by the manufacturer to ensure good air quality and system efficiency.
Proper Ventilation: Maintain proper ventilation to prevent a buildup of indoor air pollutants. Use exhaust fans when cooking or showering and consider opening windows when outdoor conditions allow.
Humidity Control: Use a dehumidifier if needed to maintain indoor humidity levels between 30-50%, which helps prevent mold growth and improves comfort.
Temperature Setting: Set your air conditioner to a comfortable temperature, typically around 72-78°F (22-26°C). Avoid extreme temperature differences between indoors and outdoors.
Programmable Thermostat: Use a programmable thermostat to adjust the temperature based on your schedule, reducing cooling when you’re not at home.
Cooling Zones: If possible, cool only the rooms you’re using rather than the entire house, which can save energy and improve efficiency.
Sunlight and Shades: Use curtains, blinds or shades to block direct sunlight, especially during the hottest parts of the day.
Seal Gaps: Ensure that doors and windows are properly sealed to prevent cool air from escaping and warm air from entering.
Fans: Use ceiling fans or portable fans to help circulate cool air throughout the room, which can make you feel more comfortable at slightly higher temperatures.
Sleeping Environment: Keep your bedroom cool and comfortable for better sleep. A slightly cooler room and lighter bedding can promote restful sleep.
Outdoor Units: Keep the outdoor unit of your air conditioner free from obstructions like vegetation or debris for optimal airflow.
