Effects of Air Conditioners on our health

Effects of Air Conditioners on our health

Its Summer time and most of us have our Air conditioners running around the clock! Have you ever wondered how this wonderful piece of technology came into existence?

The initial impetus for air conditioning technology came from the industrial sector. In the 19th century, industries such as textile mills, printing presses, and food processing plants faced challenges due to high temperatures and humidity. These conditions affected productivity and the quality of products. Engineers and inventors sought ways to regulate and control the indoor climate to improve working conditions and industrial processes.

The first modern electrical air conditioning system was invented by Willis Carrier in 1902. Carrier's invention aimed to control humidity and improve the printing process at a publishing company. This innovation paved the way for the commercialization and widespread adoption of air conditioning technology.

Since then, air conditioning technology has continued to evolve, becoming more efficient, compact, and affordable. Today, air conditioners are ubiquitous, providing cooling, dehumidification, and improved indoor air quality in a wide range of settings.  Progress in thermodynamics, refrigeration, and mechanical engineering contributed to the development of air conditioning systems. The discovery of the principles of thermodynamics, as well as advancements in refrigeration technology, provided a scientific basis for understanding how to manipulate temperature and humidity

Air conditioners can have both positive and negative effects on our health, depending on various factors. 

Here are some points to consider

Pros of Air Conditioners on Health:

Temperature Control

Air conditioners help regulate indoor temperatures, which can provide relief during hot weather or in regions with high temperatures. This can help prevent heat-related illnesses, such as heatstroke or dehydration, especially for vulnerable populations like the elderly, infants, or those with certain medical conditions.

Allergen Reduction

Air conditioners can filter out and reduce airborne allergens such as pollen, dust mites, and pet dander. This can provide relief to individuals with allergies or respiratory conditions, like asthma, by improving indoor air quality.

Humidity Control

Air conditioners can help maintain optimal humidity levels in indoor environments. Controlling humidity reduces the growth of mold, mildew, and dust mites, which can thrive in high humidity conditions. This can be beneficial for individuals with respiratory conditions or allergies.

Improved Sleep

A cool and comfortable environment facilitated by air conditioning can promote better sleep quality for some individuals. Optimal sleeping conditions, including temperature regulation, can contribute to a restful night's sleep, which is essential for overall health and well-being.

Cons of Air Conditioners on Health:

Dryness and Skin Issues

Air conditioners can reduce humidity in the air, which may lead to dry skin, dry eyes, or dry respiratory passages for some individuals. Dry air can exacerbate certain skin conditions, such as eczema, and cause discomfort or irritation.

Respiratory Concerns

Poorly maintained or improperly used air conditioning systems can circulate indoor air pollutants, including dust, allergens, or volatile organic compounds (VOCs). This can potentially worsen respiratory symptoms or trigger allergic reactions in sensitive individuals.

Temperature Extremes

Frequent transitions between extreme outdoor temperatures and heavily air-conditioned indoor environments can be stressful for the body, potentially leading to temperature-related discomfort or health issues for some individuals.

Potential for Airborne Diseases

If not properly maintained and cleaned, air conditioning systems can become breeding grounds for bacteria, fungi, or molds, which can be dispersed into the air. This can increase the risk of respiratory infections or allergic reactions.

Contributes to Global warming

Depending on the power consumed and the coolant used in the air conditioner, there is a possibility that it can affect the environment adversely. For this reason its very important to check the energy efficiency when buying an air conditioner


To optimize the health benefits and minimize potential drawbacks, it is important to maintain and clean air conditioning systems regularly, ensure proper ventilation, and set temperatures at comfortable levels. Balancing the use of air conditioners with natural ventilation, like opening windows, can also be beneficial. Additionally, individual tolerance and sensitivity to air conditioning may vary, so it's advisable to listen to your body and adjust usage accordingly.
