Aircon Ailments: Common Side Effects Associated with Prolonged Use

Many people use air conditioning to stay cool, but they notice problems. Prolonged use can cause dry skin and tiredness. Our article offers insights on common health issues from air conditioners and tips to avoid them.

Keep reading for helpful advice.

The Impact of Air Conditioning on Health

Turning on air conditioning can lead to health issues that many might not immediately link to its use. Common effects include dryness affecting the skin and eyes, along with an increase in respiratory problems.

Dehydration and Dry Skin

Air conditioning systems play a significant role in maintaining indoor climate control, especially during extreme heat. Yet, these systems can significantly reduce humidity levels indoors, leading to potential skin dehydration.

The constant exposure to dry air can strip the skin of its natural moisture, resulting in rough and itchy skin surfaces. This effect not only causes discomfort but may also exacerbate existing conditions such as eczema or dermatitis.

Proper hydration and the use of moisturizers become crucial in environments dominated by air conditioning. With the skin constantly battling against the drying effects of conditioned air, replenishing lost moisture is essential for keeping the skin smooth and preventing dryness-related ageing signs like wrinkles or creases.

Additionally, people with sensitive skin conditions need to be extra vigilant as air-conditioned surroundings might worsen symptoms associated with atopic dermatitis or senile xerosis.

Headaches and Respiratory Issues

Prolonged exposure to air conditioning can lead to dehydration, a key factor behind the onset of headaches. This condition often exacerbates chronic headaches and fatigue, especially in environments where air conditioning is used excessively.

The cold temperatures generated by these systems can also contribute significantly to the discomfort experienced by individuals suffering from headache disorders.

Respiratory issues are another common consequence of extended air conditioner use. With indoor air quality potentially compromised by airborne allergens and pathogens circulated through HVAC systems, those with pre-existing respiratory conditions may find their symptoms aggravated.

Conditions such as asthma and bronchial inflammation can intensify in over-air-conditioned spaces, highlighting the importance of maintaining clean ventilation systems for both health and comfort.

The Connection Between Air Conditioning and Allergies/Asthma

Air conditioning units can play a significant role in triggering allergies and asthma. Low-dose exposure to volatile organic compounds (VOCs) emitted by air conditioners may cause acute asthma attacks.

These substances, found in the refrigerants and coolants of air conditioning systems, can be particularly harmful to individuals with sensitive airways. In addition, microbiological contamination within the heating, ventilation, and air conditioning (HVAC) systems poses a risk factor for developing asthma due to the proliferation of airborne allergens such as dust mites and mould spores.

Exposure to particulate matter from air-conditioning also contributes to lower lung function and inflammation of the lower and upper airways. This can lead not only to increased hospitalizations for asthma but also exacerbate symptoms like coughing, sneezing, runny nose, and respiratory distress among asthmatics.

Furthermore, conditions inside an air-conditioned environment—such as lowered humidity—can dry out mucous membranes inside the nose making them more susceptible to infections that may provoke or worsen allergic reactions and asthmatic episodes.

Examining the Impact of Air Conditioning on Indoor Environments

Installing air conditioning systems in buildings significantly alters the indoor environment, affecting temperature, humidity levels, and air quality. Low fresh air ventilation can contribute to sick building syndrome, a condition where occupants experience acute health and discomfort effects without any specific illness being identified.

This syndrome is more common in office settings where people spend extended periods within air-conditioned environments. The control over temperature and lighting through HVAC systems can play a substantial role in either alleviating or exacerbating these symptoms.

The impact on indoor environments goes beyond comfort, potentially influencing the spread of infectious diseases such as the flu or even the SARS-CoV-2 virus responsible for the COVID-19 pandemic.

Air conditioning systems that do not properly filter air or circulate fresh outdoor air can facilitate airborne transmission of viral particles across enclosed spaces. Furthermore, low humidity levels often found in overly cooled areas can dry out mucous membranes in noses and throats, making individuals more susceptible to viral infections.

Addressing these issues involves regular maintenance and considering modern updates to HVAC systems capable of filtering particulates and maintaining an adaptive comfort model beneficial for public health.

Air Conditioning’s Role in Noise Pollution and Indoor Pollutants

Air conditioning units contribute to noise pollution, especially in densely populated areas. The constant hum and operational sounds of both outdoor and indoor units disrupt silence, potentially leading to increased stress levels among residents.

This noise can interfere with daily activities such as sleeping or concentrating on work.

Additionally, air conditioners play a significant role in circulating indoor pollutants. Central air conditioning systems, if not adequately maintained, spread bacteria, mould, and mildew throughout the building.

These contaminants can harm people’s health by causing respiratory infections, coughs, and other health issues related to poor indoor air quality. Regularly maintaining these systems is crucial to minimize the risk of such adverse health effects.


Understanding the health implications of prolonged air conditioning use highlights an essential part of modern living. Recognizing symptoms like lethargy, dry skin, and respiratory issues can prompt healthier indoor environments.

It’s crucial to find a balance between comfort and well-being by adjusting settings and taking regular breaks from cooled spaces. Implementing these measures ensures that while enjoying the benefits of climate control, one also safeguards against potential health risks.

Embracing such practices fosters both comfort and good health in air-conditioned surroundings.

For a deeper dive into how air conditioning affects our indoor spaces, check out our detailed article: Examining the Impact of Air Conditioning on Indoor Environments.


1. What are some common side effects of using air conditioning for a long time?

Prolonged use of air conditioning can lead to migraines, lethargy, dry or itchy skin, dry eyes, rhinitis, and pharyngitis due to indoor air pollution.

2. Can air conditioning increase the risk of respiratory symptoms?

Yes, heating and cooling systems like air conditioning can circulate infectious agents such as viruses and bacteria spores, potentially increasing the risk of respiratory symptoms and diseases like influenza.

3. How does air conditioning affect our skin and eyes?

Air-conditioned environments often have low relative humidity which dehydrates the skin making it dry or itchy. It also causes dry eyes by reducing water vapour in the air.

4. Does prolonged exposure to aircon contribute to heat-related illnesses?

Ironically yes! Leaving an air-conditioned space in high heat exposure areas without proper acclimatization could elevate risks for conditions like heat exhaustion or even heat stroke.

5. During pandemics like COVID-19, is using an AC safe?

While ACs themselves do not spread viruses like the SARS-CoV-2 virus responsible for the COVID-19 pandemic; poor ventilation might aid in circulating infected aerosols if present indoors leading to higher transmission rates among individuals within these enclosed spaces.

6. Are there any occupational health concerns associated with working in constantly air-conditioned environments?

Working continuously under heating and ventilation systems may expose employees to allergens and pollutants that cause ailments from minor irritations such as headaches to more serious conditions including various forms of rhinitis or even exacerbate asthma due to constant exposure to conditioned but possibly polluted indoor air.
