Air Conditioning and Human Health - Pros and Cons

Air conditioning protects us from summer heat, reduces the risk of overheating, and today is considered an essential element for creating a comfortable environment. However, along with all its benefits, air conditioning may also have certain negative effects on our health.

“NOVA,” together with high-quality equipment, offers useful tips to help you use your air conditioner with maximum comfort and without health risks. In this blog, we will discuss both the positive and negative aspects of air conditioning in relation to health and provide practical advice for its optimal use.

Positive Effects of Air Conditioning

Alongside helping you escape the heat and maintain productivity, air conditioning can bring significant health benefits.

Protection from Heat and Thermal Comfort
One of the main advantages of air conditioning is protection from heat and ensuring thermal comfort. During peak summer periods, when temperatures exceed 30°C, the risk of overheating and heat-related damage increases. In such situations, the most vulnerable groups are the elderly, infants, and people with cardiovascular conditions. In extreme heat, an air conditioner helps protect the body from overheating.

Air Filtration and Reduction of Allergens
Air conditioners are equipped with filters that clean indoor air from dust, bacteria, pet dander, and other allergens. This function is especially important for people with allergies and asthma. Modern air conditioners with HEPA (High Efficiency Particulate Air) filters remove 99.97% of particles larger than 0.3 microns from the air, including the most common allergens.

Humidity Control and Mold Prevention
Modern air conditioners also regulate humidity, which is an important factor in creating a healthy environment. Excess moisture promotes mold growth on walls and ceilings, increasing the likelihood of fungal spores.

According to the World Health Organization, to prevent moisture-related health issues, indoor relative humidity should be maintained within the range of 40-60%. Modern air conditioners, with humidity control functions, automatically maintain the desired level and help create a healthy environment in homes and offices.

Negative Effects of Air Conditioning on Health

Despite its many benefits, there are certain risks associated with improper or excessive use of air conditioning systems.

Weakened Immunity and Frequent Colds
The use of air conditioning is sometimes associated with weakened immunity and frequent colds. When a person stays for a long time in a conditioned space and then moves into a much warmer environment, the body may struggle to adapt to the sudden temperature change. This thermal shock can irritate the respiratory system and increase the risk of viral infections.

For example, office employees who constantly work in air-conditioned environments often complain about sore throats and runny noses. Prolonged exposure to heavily conditioned spaces can reduce the body’s thermoregulation ability and weaken its natural defense mechanisms.

Dry Skin and Respiratory System
A side effect of air conditioning can be dryness of the skin and respiratory tract. Air conditioners reduce humidity levels, which negatively affects mucous membranes. The skin may lose elasticity, become dry, flaky, and itchy.

Sick Building Syndrome and Headaches
“Sick Building Syndrome” (SBS) refers to a group of health issues such as headaches, irritation of the eyes, nose, and throat, fatigue, and dizziness. The main causes include poor indoor air quality, inadequate ventilation, and chemical pollutants.

According to the World Health Organization, potential causes of SBS are observed in 30% of new and renovated buildings. Air conditioning systems can also contribute to the development of SBS. Poor maintenance of filters may lead to the accumulation of bacteria, mold, and harmful substances.

Tips for Safe Use of Air Conditioning

To use your air conditioner safely and protect your health, follow these recommendations:

Regular cleaning and filter replacement are essential to prevent the accumulation of bacteria, mold, and other pollutants in the air;
Try to keep the temperature difference between indoor and outdoor environments within 8°C to reduce discomfort and health risks;
Avoid sleeping or sitting directly under the airflow, as it can cause muscle stiffness and neck pain - place the unit so that the airflow is not directed at people;
Air conditioning can lead to dehydration - make sure to maintain your daily fluid intake;
Dry air can irritate mucous membranes and increase susceptibility to infections - try to maintain indoor humidity at 30-50%;
Do not turn off the air conditioner abruptly - sudden temperature changes can put stress on the body. Use programmable settings to maintain a stable and optimal temperature.

By following these tips, you can enjoy the benefits of air conditioning while minimizing its potential negative effects on your health.
