Recognizing Common Side Effects of Lengthy Aircon Use

Air conditioning is a way to keep our rooms cool. It’s used everywhere, from homes to offices. But staying in air-conditioned spaces for too long can cause problems. For example, it can make your eyes dry and irritate your breathing paths.

This is tough for people with asthma or allergies.

Using an aircon too much can also harm your skin by making it dry and flaky. Even worse, it might age faster. People often feel tired, get headaches, don’t sleep well, and don’t drink enough water when they’re always in cool air.

Plus, if we use air conditioners all the time, we use more power which leads to more pollution.

To avoid these troubles, we should take care of our ACs and choose energy-saving ones when we can. Try using natural ways to cool down and remember to drink lots of water! We could even switch off the AC sometimes – like when the weather’s nice outside.

This article talks about how being in cold rooms for ages isn’t great for us and what we can do about it. Read on to learn more!

Understanding the Impact of Air Conditioners on Indoor Air Quality

Air conditioners can change the air we breathe indoors. They cool the air but can also remove moisture, leaving it dry. This dry air affects our comfort and health. It can absorb moisture from everything it touches, including us.

Poorly maintained AC units are a problem too. They might not filter the air properly, letting dust and allergens circulate in a room. Mold may grow inside them if they’re damp or dirty.

This mold then spreads through the air, causing allergies or making asthma worse. Dirt and dust in filters can cause similar problems when air blows past them.

Clean and well-kept ACs make indoor air fresher and cleaner to breathe. But even these need checks to stop dirt buildup or mold growth over time. It’s key for people with breathing troubles to live in spaces with good quality indoor air free of pollutants.

Common Side Effects of Lengthy Aircon Use

Extended exposure to air-conditioned environments can introduce a range of adverse health effects that often go unnoticed until they exacerbate. From subtle changes in our body’s hydration levels to more pronounced respiratory conditions, the continuous use of air conditioners bears a compendium of side effects with varying degrees of impact on our well-being.

Dry Eyes

Air conditioners can cause dry eyes. This happens because they reduce the moisture in the air. Low humidity levels mean that tears evaporate faster than usual. People feel a scratchy sensation or like something is in their eye.

Air-conditioned rooms often have this problem.

To help with dry eyes, you should blink more often. It’s also good to take regular breaks from screens. Using artificial tear drops can keep your eyes moist too. It’s important to maintain room humidity as well.

You might want to use a humidifier in rooms where you spend lots of time.


Just as dry eyes can result from prolonged exposure to air-conditioned environments, dehydration is another consequence to be wary of. The cool air that keeps you comfortable also strips moisture from the room and your body.

This can leave you feeling dehydrated if you’re not mindful about drinking water regularly. Symptoms include headache, fatigue, dry lips and skin, as well as dizziness—the signs shouldn’t be ignored.

Actively ensuring adequate hydration is vital whilst in air-conditioned spaces for long periods. Sipping on water throughout the day maintains fluid balance and helps fend off the drying effects on your system.

Remember to listen to your body’s needs and keep a bottle of water at hand—your health will thank you for it.


As dehydration from prolonged AC use can impact our bodies, it’s not surprising that headaches often follow. Dry air may reduce moisture levels in the mucous membrane inside your nose and mouth, leaving you prone to pain in your head.

Not getting enough water makes matters worse by causing tiredness and making it hard for you to focus. These effects together can trigger headaches or even worsen migraines.

Many find that a stuffy workplace with poor airflow adds to the problem. This situation sometimes leads to sick building syndrome, where headaches are common complaints among other health concerns.

Keeping hydrated is crucial if you’re spending lots of time in an air-conditioned environment, along with ensuring good ventilation to dodge these discomforts.

Respiratory Problems

Air conditioners can sometimes cause trouble breathing. They dry out the air, which might irritate your lungs. If you already have a breathing problem, like asthma, an air conditioner could make it worse.

The cold and dry air can lead to more coughing and wheezing.

Using an AC often may also increase dust and pollen in your home because these particles get trapped inside. This can cause allergies to act up. Your nose might feel stuffy or runny more than normal.

It’s important to keep your AC clean to stop these problems from happening.

Dry Skin

Moving from respiratory issues to skin concerns, long hours in an air-conditioned environment can be tough on your skin. The cold and dry air strips moisture away, leaving it feeling stretched and flaky.

This constant exposure may even speed up the ageing process.

To battle dryness, applying lotions that are rich in moisture helps a lot. They rehydrate the skin’s surface. For deeper care, use creams over lotion to seal in that much-needed moisture and protect your skin from the dehydrating effects of the AC.

Regular moisturising is key to maintaining healthy, supple skin despite being in climate-controlled surroundings for extended periods.


Continuing from dry skin, another uncomfortable effect of prolonged aircon use is lethargy. This sluggish feeling makes you feel tired and without energy. It often comes from being in low temperatures for too long.

An air-conditioned room can be cool but may also drain your energy levels. The body works harder to keep warm, which can make you feel slow and sleepy. Along with dehydration, these conditions create the perfect storm for feeling lethargic.

Remembering to stay hydrated and keeping the room not too cold are key ways to combat this tiredness.

Asthma and Allergies

Air conditioners could make asthma and allergies worse. They often cool air by removing moisture, which dries out nasal passages. This dryness can trigger asthma attacks or allergic reactions in people who are sensitive.

Aircon units also circulate indoor air pollutants that may contain allergens like dust mites, pollen, or pet dander.

People with allergies might suffer more in rooms with air conditioning. The cold, dry environment is perfect for irritating the respiratory system. Some feel their symptoms flare up as soon as they step into a chilled room.

Keeping AC filters clean reduces these risks but does not eliminate them entirely. Regular maintenance of air-conditioning systems should be a priority to protect against asthmatic reactions and manage allergy symptoms effectively.

How to Mitigate and Prevent these Side Effects

Long use of air conditioners can cause some health issues. Here are ways to help prevent and reduce these side effects:

  • Keep room temperature steady to avoid sudden changes that stress the body and affect skin.
  • Use a humidifier to balance the moisture level in the air, which can prevent dry eyes and skin.
  • Drink plenty of water throughout the day to stay hydrated even when you’re inside.
  • Place bowls of water in rooms with AC to add moisture back into the environment, reducing irritation.
  • Limit AC use by turning it on only during the hottest parts of the day or when truly necessary.
  • Apply lotions rich in moisture after a shower and again before bed; this keeps your skin hydrated.
  • Use creams to lock in moisture following lotion application, protecting against flaking and aging.
  • Opt for natural ventilation like open windows or fans where possible, allowing fresh air circulation.
  • Regularly clean and maintain your AC unit to ensure it works efficiently without circulating dust or allergens.
  • Avoid sudden shifts from cool indoor environments to high outdoor heat which can shock your system.
  • Wear wrap – around sunglasses if you experience evaporative dry eye when going outside after being in an AC room.
  • Consider using nasal washes or sprays if you have issues inside your nose caused by dry airways from constant AC exposure.
  • Practice the Valsalva maneuver if you feel ear pain due to blocked eustachian tubes from rapid temperature change.
  • Protect ears, nose, and throat health by avoiding very cold settings on your air conditioning system.
