What happens to us and our bodies if we're in the air conditioning all day?

During the summer months, when temperatures soar and the heat becomes unbearable, many people rely heavily on air conditioning systems to keep their homes cool and comfortable. However, despite its widespread use, there are several common misconceptions about how to effectively utilize these devices without causing unnecessary strain on them or increasing electricity bills. Experts warn that simply setting the thermostat to the lowest possible temperature does not necessarily result in the most efficient cooling. In fact, such practices can lead to higher energy consumption and increased wear on the system, especially during extreme heat conditions.

The ideal approach involves maintaining a stable indoor temperature around 25.5 degrees Celsius, which strikes a balance between comfort and energy efficiency. This method prevents the air conditioner from overworking, as sudden drops in temperature can cause the unit to labor excessively once the space has warmed back up. Additionally, it's a misconception that turning off the AC completely when away from home is the best option. Instead, adjusting the temperature slightly higher while absent helps prevent the system from having to work harder later to bring the room back down to a comfortable level.

Another crucial factor in ensuring the effective operation of an air conditioner is the maintenance of airflow. Regular cleaning of filters every few months is essential to maintain proper function. Clogged filters reduce the system’s efficiency and can even lead to freezing issues in severe cases. Furthermore, attention should be paid to the external unit by clearing debris such as leaves and grass around it, ensuring at least 60 centimeters of free space for the proper dissipation of heat.

During the hottest part of the day, closing blinds and curtains plays a vital role in preventing sunlight from entering the room. Minimizing the use of appliances that generate additional heat, such as cooking equipment, also contributes significantly to reducing the load on the air conditioning system. Using a fan in the bathroom after showering can further help by removing excess moisture, which otherwise complicates the cooling process. Adhering to these simple tips ensures optimal performance of the device and long-term comfort throughout the entire summer season.

Many users are unaware of a hidden feature available on nearly all air conditioners—desiccant mode or the water droplet symbol on remote controls. Unlike conventional cooling functions, this mode focuses more on removing excess humidity rather than lowering the temperature directly. As a result, rooms can feel noticeably cooler even if the thermometer shows a slightly higher temperature than desired. The sensation of heat is influenced not only by temperature but also by the humidity levels in the air. High humidity makes sweat evaporate more slowly from the skin, making it harder for the body to dissipate excess heat, leading to feelings of stuffiness even after prolonged use of the air conditioner.

Using the desiccant mode reduces the workload on the compressor, which is the component that consumes the most electrical energy. Since the main task of this mode is dehumidification, the compressor operates with less load and frequently pauses its activity. Therefore, the power consumption in many cases is lower compared to using the standard cooling mode. The amount of savings depends on the type of air conditioner, ambient temperature, and humidity levels in the room.

This function proves particularly useful during hot summer days when the air contains high levels of moisture. In recent weeks, relative humidity levels have reached up to 80 to 90 percent following rain showers, while temperatures remain high. Activating this function for approximately one hour before extended stays in the room can make the air easier to breathe, even if the temperature hasn't changed significantly. Many users employ this mode while sleeping because the air conditioner doesn’t cool the room as intensely in this setting, reducing the likelihood of waking up due to excessive cold. Maintaining a pleasant level of humidity further enhances the feeling of freshness.

While many people adjust the air conditioner to 18 or 20 degrees Celsius to combat the heat, removing excess moisture allows the body to naturally cool itself, making a temperature of around 25 degrees Celsius entirely comfortable. Thus, the dry mode can be a simple way to improve the sense of freshness in one's home during the summer, while also relieving the air conditioner and potentially reducing electricity consumption.

Air conditioning has become an almost indispensable part of daily life, especially during the summer months when temperatures reach extreme values. However, concerns arise regarding whether continuous exposure to air-conditioned environments poses health risks and whether fears associated with air conditioners are justified. Experts emphasize that properly used and regularly maintained air conditioners generally provide more benefits than harm, although improper usage can lead to certain health discomforts.

Air conditioning can literally save lives during heatwaves by significantly reducing the risk of heatstroke, exhaustion, and other consequences of high temperatures, particularly among the elderly, children, and individuals with chronic illnesses. High temperatures represent one of the leading causes of mortality related to weather conditions, highlighting the importance of cooled spaces in protecting health.

Spending time in comfortably cooled areas can enhance concentration, work ability, and sleep quality. Research indicates that people in overheated rooms think slower, make decisions more difficultly, and are more prone to errors in everyday tasks. Lower temperatures during the night facilitate falling asleep and contribute to better rest.

However, potential problems often stem not from the air conditioner itself but from how it is used. Air conditioners can dry out the air, potentially causing dry eyes, dry skin, nasal and throat irritation, coughing, and headaches in some individuals. Those suffering from asthma or other chronic respiratory diseases may be more sensitive to such changes. Dirty filters pose a risk as they can develop mold, fungi, and bacteria that degrade air quality. Therefore, experts recommend regular cleaning of filters and annual servicing of the unit.

Large temperature differences are not advisable. A common mistake is setting the temperature to 18 or 19 degrees Celsius when the outside temperature exceeds 35 degrees. Such abrupt changes can stress the body and lead to headaches, muscle pain, stiff neck, or worsening of respiratory symptoms in sensitive individuals. Most experts recommend setting the air conditioner between 24 and 26 degrees Celsius, ensuring that the difference between outdoor and indoor temperatures does not exceed seven to eight degrees. It is important that the cool air is directed towards the ceiling or walls rather than directly at people to distribute evenly throughout the room.

Ventilation is also crucial. Although air conditioners cool the space, they cannot fully replace fresh air. Periodic ventilation of rooms helps reduce carbon dioxide concentrations and improves air quality in enclosed spaces. Spending time in an air-conditioned environment itself is not harmful; instead, it can significantly protect health and reduce the risk of heatstroke during intense heat periods. Problems mainly arise when the air conditioner is used improperly, when the temperature is too low, or when the device is not regularly maintained. With moderate use, regular filter cleaning, and adequate fluid intake, the air conditioner remains one of the safest ways to protect against summer heat.
