Can your air conditioning make you feel sick?

Air Conditioner sickness symptoms


Yes, an air conditioner unit can make you feel sick. But the main culprit here is not your air conditioner unit. The main reason for the air conditioning sickness symptoms is cold air coming from your AC, which may be unhealthy due to internal issues. The reasons for your unwanted trouble are the side effects of the air conditioning unit. This means that your air conditioner unit interacts with the environment to produce a favourable environment for specific health issues.

As we observe the simplified mechanism for an air conditioner, it circulates the air in your room or house, and if your space consists of pollutants or dust, they will also be easily dispersed in the place. These pollutants and dust end up triggering your health issues very quickly.

Taking a simple example, suppose you have dirty dander floating around or sufficient dangerous bacteria present in the room. In this case, air conditioning will cause these dirty and harmful pollutants to circulate, which can cause sickness symptoms like sore throats, red noses, or vital respiratory issues.

Also, if your air conditioner unit is not well maintained, which means it has not gone for maintenance servicing for a long time, it can be a source of mold growth and bacteria in its internal structure. As air passes through your AC, these bacteria too can escape into your room.

If you enjoy blasting your cooling and chilled, frigid temperatures can also be a source of sickness. Extreme cold leads to dryness symptoms, the spread of viral causing viruses, and significantly decreases the immune response.

What is air conditioning Sickness Syndrome?

Sick building syndrome-SBS is defined as the symptoms of certain health illnesses and discomfort by the occupants of a building. While ill building syndrome is mainly linked to poor air quality, there can be many culprits such as dust, heat or low humidity, the presence of Mold, poor ventilation, tobacco smoke, lousy lighting, and more.

SBS does not specify any disease or illness. This condition is often linked to the time spent in a place, and when you leave the area, the symptoms improve or disappear. These symptoms are often related to the air-borne contaminants and pollutants in that particular place.

The non-specific symptoms of the sick building syndrome include mostly irritated and itchy skin, breathing problems, headache, and fatigue.

Coming to the central part of the article, we have summarised the 10 most common air conditioning sickness symptoms in a very concise and focused way. We have divided this content section into two parts.

Fortunately, the symptoms do not include any chronic illnesses but can leave adverse effects if ignored for a more extended period.

Let’s look at the ten most common air conditioning sickness symptoms that you should be worrying about.

Visible suspected Mold


If you see any suspected visible mold on your wall surfaces, around the AC vents, or any part of your AC unit, you should question the Mold symptoms in your air-conditioned room or place. Mold particles can become air-borne and circulate with the conditioned air places and spaces.

  • Symptoms-
  • The condition includes symptoms like wheezing, throat irritation, and congestion.
  • Solution-
  • It is best to glance inside your air conditioner’s internal structures like ducts and vents and try to spot any signs of suspected mold growth. 
  • Once the problem is detected, immediately call a professional to deal with the situation and stop further infestation.

Breathing or respiratory problems

Most people suffer from breathing and respiratory issues when they sit in a room with an air conditioner. This often happens when the air conditioner unit and its air filters are not cleaned or changed when needed.

Air filters trap dirt, bacteria, and fungi. The air filters will start releasing these air-borne particles into your room when not cleaned on time instead of filtering them out! As a result, you begin breathing in polluted air resulting in air conditioning sickness.

  • Symptoms-
  • breathing and respiratory difficulties and breathlessness.
  • Solution-
  • you need to clean your AC unit with the help of a professional.

Cold and Allergic symptoms

Suppose you, out of nowhere, start to feel cold or experience allergy-like symptoms when sitting below or around an AC, and the symptoms disappear as soon as you turn the cooling off. Often the symptoms are related to the clogged and blocked dirty filters and need to look for maintenance and cleaning.

  • Symptoms-
  • This condition may include coughing, sneezing, wheezing, throat irritation, runny nose, etc.
  • Solution-
  • Contact a professional technician immediately to book a maintenance check-up.

Dry and itchy skin mucous membrane

Your air conditioner chills down your house by removing the extra moisture from indoor air. This may result in dry and flaky or itchy redness skin. Running your air conditioner unit for a too long time may bring down the humidity to deficient levels. 

On the other hand, low humidity leads to the evaporation of water vapors from your skin surface, ultimately resulting in dryness and flaky skin. It is essentially recommended to keep the vanes upwards so that the chilled air doesn’t hit your skin directly.

  • Symptoms-
  • dry and flaky skin.
  • Redness and itching.
  • Solution-
  • You can always opt for using a humidifier to maintain optimal indoor humidity, prevent the temperature from being too cold, or use an intelligent air conditioner controller unit or the thermostat to maintain room humidity levels along with an air conditioning unit. 
  • Also, keep in mind to moisturize your skin frequently and drink plenty of water to keep your skin hydrated.

Irritated dry and red eyes

The air conditioning unit decreases indoor humidity levels. The reduced humidity levels often lead to the evaporation of tears and essential liquid from your eyes. This can lead your eyes to dry and irritated with redness. People who are already suffering from dry eye syndrome due to some reason should not sit in air conditioning for too long.

  • Symptoms-
  • dry and itchy red eyes.
  • Solution-
  • try to avoid long-term use of the AC unit.

Dehydration symptoms

The dehumidification procedure that keeps your room cool by your air conditioner leads to a meagre moisture count indoors. This low humidity level by your AC unit increases the process of evaporation of essential water and fluid content from your body. Therefore, it is noticeable that when the temperature is set at a shallow point, you feel cold and need to drink water.

  • Symptoms-
  • increased water thrust
  • body feels dehydrated 
  • mouth dryness
  • Solution-
  • Avoid long-term use of AC units.
  • Keep in mind to maintain your hydration levels.

Prolonged headache

You might have noticed that you, out of nowhere, feel uncomfortable and dizzy or suffer from prolonged headaches when you are in an air-conditioned room for too long. The reason behind this is dehydration that the constant dehumidification leads to.

  • Symptoms-
  • apart from headaches and an uneasy state, you may suffer from dehydration symptoms.
  • Solution-
  • Have a habit of drinking water or fluids when you are long-term use of your AC unit.

Increased Blood Pressure

The temperature is the main factor that indirectly affects our blood pressure and overall health. To maintain the proper body temperature, the small arteries and capillaries constrict the loss of body heat. This resistance leads to increased blood pressure.

  • Symptoms-
  • high blood pressure without any underlying cause or symptoms.
  • Solution-
  • People who suffer from hypertension should strictly avoid a shallow thermostat setting and keep it as minimum as possible.

Feeling tired and lazy.

When you are in an air-conditioned room or house, your body burns energy while trying to keep itself warm to maintain body temperature—this constant burning of energy results in prolonged tiredness. The cold air may also lead to muscles stiffness, making you feel exhausted and lazy all the time.

  • Symptoms-
  • Muscle stiffness
  • tired and lazy morning
  • Solution-
  • try to wake up in the fresh air,

Heat Intolerance

No one likes to roam around when the heat is intense, but if it has become nearly impossible for you to stand the extreme heat, then you have become heat intolerant. 

People who get dependent on air conditioning units often are prone to become intolerant of the sweltering heat.

  • Symptoms-
  • Extreme heat intolerance.
  • Solution-
  • try to keep using a fan when you are in a Milder and more relaxed atmosphere.
