Protect yourself from potential harms of air conditioners

According to experts, here are 8 threats that can affect your body directly if you spend too much time in an air-conditioned environment.

1. Increased risk of infection

If you do not clean the air filter regularly, bacteria that build up in air conditioner will adversely affect your health. Therefore, to minimize the risk of infection, you need to clean or replace the air conditioner filter every 4 - 6 months. In addition, air-conditioned environment can also increase the body's exposure to bacteria and fungi. That is why you should regularly maintain your air conditioner to avoid potential health risks and protect your skin.


2. Cold-like symptoms

Staying in air-conditioned environment will make it easier for you to experience the same symptoms as colds. As the air conditioner reduces the humidity of the air, when the temperature is hot, it increases the risk of dry eye or sore throat. In particular, people with weak resistance can easily feel symptoms such as headache, stuffy nose or fever.


3. Increased risk of Legionnaires

Legionnaires are lung infections (pneumonia) caused by Legionnaires bacteria. The cause of the disease comes from inhaling Legionnaires bacteria in moist or dusty environments. However, the living environment of these bacteria can also be detected in spray equipment, refrigerated chassis of air conditioner.


4. Increased risk of Raynaud

Raynaud is a blood vessel injury when you have cold or stress, causing discoloration (white, gray or black) at the extremities. In particular, this phenomenon of decreased blood flow is most often found in the tips of fingers. Therefore, if Raynaud patients stay in a cold environment for too long and the temperature is too low, they might experience painful, numb or itchy fingers. So when you face this situation, increase the air temperature or get out to enjoy natural air.


5. Worsened arthritis pain

 For some, especially people with arthritis, excessive exposure to air conditioning can increase joint stiffness and cause pain. The cause of this symptom is associated with exposure to low temperature and humidity. To minimize this condition, you can use a humidifier or warm blanket if you are in a cold environment for a long time. In addition, using essential oils can also help relieve aches and pains.


6. Worsened allergic symptoms

Most air-conditioner allergy are related to respiratory tract diseases such as allergic rhinitis, sinusitis... Since air conditioning dries the air, it leads to lack of moisture, which makes nasal mucosa dry and sensitive. Especially if the air conditioner is not clean, it will cause nose irritation in people with weak or sensitive resistance. However, in some cases, conditioning is useful for people with allergies because it reduces the need to open windows.


7. Increased risk of asthma

If you have asthma, contaminated air conditioners can make your situation worse due to a significant temperature difference between the outside and the inside of the room or due to air conditioning. Therefore, people with asthma should pay more attention to health care in the hottest months.


8. Dry skin

If you spend a lot of time in an air-conditioned environment, you can feel your skin getting dry and losing moisture. This will cause problems like premature skin aging and skin degeneration. One of the best treatments is to drink plenty of water and use moisturizing cosmetics to maintain soft skin.
