A poorly cleaned unit may cause cold and flu-like symptoms from the mold or bacteria in the unit. The dry environment also contributes to your discomfort. Regular maintenance and proper cleaning helps reduce the risk of feeling sick from your air conditioner.
You may experience sneezing, coughing, or a sore throat from air conditioning. These symptoms usually occur due to hair or dust in the air, not viruses or bacteria. Colds and cases of flu can cause the above symptoms. You may develop a fever, runny nose, or headache if you have a cold.
That's not to say airborne viruses and bacteria — such as those that cause tuberculosis, the common cold, the flu and certain fungal infections — can't pass through an AC unit in theory. But health agencies explain that their primary modes of transmission are close person-to-person contact.
Dry eyes, lethargy, dehydration, dry or itchy skin, headaches, respiratory issues, allergies and asthma, noise pollution, infectious diseases, and indoor pollutants are among the common health concerns associated with prolonged exposure to air conditioning.
If the AC unit is not well maintained, it can circulate dust, mould, bacteria, and other allergens, which can cause respiratory issues, allergic reactions, or exacerbate asthma symptoms.
Indicators of SBS include:
Building occupants complain of symptoms associated with acute discomfort, e.g., headache; eye, nose, or throat irritation; dry cough; dry or itchy skin; dizziness and nausea; difficulty in concentrating; fatigue; and sensitivity to odors.
It is advisable to use a humidifier alongside your home conditioner if you experience any air conditioning sickness symptoms. Also, drink a lot of water during the day to reduce this effect.
When your air conditioner is on, any mold, mildew, bacteria, and other allergens in the home get airborne. You can end up breathing this airborne matter in, and since the air conditioner can also dry out the air, it can irritate your nose and throat as well.
Symptoms of air conditioner lung typically appear four to six hours after exposure to the allergen and may last anywhere from 12 hours to a few days. The symptoms of A/C lung are similar to those of COVID-19, so it's probably a good idea to get tested for COVID if you experience any of the symptoms.
Legionella bacteria can proliferate in air conditioning systems, particularly in cooling towers. Inhalation of contaminated aerosols can lead to Legionnaires' disease, a severe form of pneumonia. Symptoms include high fever, cough, and muscle aches. In extreme cases, it can be fatal.
Cooler temperatures at night can cause our immune system to slow down. This can make you more susceptible to conditions like common cold or a dry cough. Or else, you might wake up with a sore throat. If the AC unit is not clean, it will circulate germs and other airborne contaminants like dust mites, pet dander, etc.
In more severe cases, avoidance may not be enough. Then, treatment may include corticosteroids or other immunosuppressive medication to reduce inflammation and prevent your immune system from reacting to the allergens you inhale.
A dirty AC system can lead to many breathing problems. If you have a runny or stuffy nose that develops when you're inside but goes away when you leave, this is a clear indication that your air conditioner's filter is dirty.
Drink more water to keep yourself hydrated and your throat and nasal passages moist. If you are experiencing exhaustion, headaches, and sore muscles and joints, turn that air conditioning down! Your air conditioner should be set at a comfortable, room temperature.
Can an air conditioner cause a sore throat? Yes, it can. Air conditioners remove humidity from the air, which can leave your throat feeling dry and sore, especially first thing in the morning. The AC isn't the only factor, of course, but fixing some common problems can resolve your sore throat woes.
If you work in an air-conditioned building with poor ventilation, it can raise your risk of “sick building syndrome.” Symptoms include headaches, dry cough, dizziness and nausea, trouble concentrating, fatigue, and sensitivity to odors.
Exposure to AC will affect respiratory health
Sleeping in a room with the AC on can lead to respiratory problems, particularly for individuals who are sensitive to cold air or have existing respiratory conditions such as asthma or allergies.
They can make your family sick:
Your family may suffer upper respiratory infections if they experience coughing, headaches, sneezing, nasal congestion, sore throats, runny noses, and low fevers due to dirty air-conditioning filters.
Contamination and Germs
One cause of this could be central air conditioning circulating old stagnant air rather than bringing in fresh air from outside. Meaning that if there is mold, dust, animal dander, viruses, or airborne infections floating about, then individuals are more likely to be exposed and get sick.
Air conditioning impact on respiratory health
In healthy individuals, exposure to air conditioners with very cold air can cause alterations in the respiratory airways that, in the context of pre-existing conditions such as asthma, can increase the risk of developing a respiratory illness.
Repeated or prolonged exposure to high levels of some VOCs can cause blurred vision, headaches, nausea, dizziness, coughing, burning eyes, respiratory irritation, skin rashes, respiratory illness, concentration difficulties, and other symptoms.
