Air conditioning has become an integral part of our lives, providing thermal comfort on hot days. Whether in homes, offices, stores or cars, we enjoy pleasant coolness, protecting ourselves from the heat. However, have we ever wondered what effect air conditioning has on our health? Can prolonged stay in air-conditioned rooms have negative consequences?
Benefits of air conditioning for health
There’s no denying that air conditioning brings relief on hot days, and this translates into a number of benefits for our health:
- Overheat Protection: Air conditioning helps maintain optimal body temperature , protecting against heat stroke and other ailments related to overheating of the body. This is especially important for the elderly, children and people with cardiovascular diseases.
- Better sleep quality: In an air-conditioned room, it is easier to have a restful and restorative sleep. High temperatures can make it difficult to fall asleep and cause frequent awakenings.
- Increased efficiency: Studies show that we are more focused and efficient in comfortable thermal conditions. Air conditioning in the workplace can therefore contribute to improving efficiency.
- Allergen reduction: Some air conditioners are equipped with filters that clean the air of pollen, dust and other allergens. This can bring relief to allergy and asthma sufferers.
- Insect protection: Air conditioning can help reduce the presence of insects indoors, which is especially important for people who are allergic to their bites.
Potential risks of air conditioning
Despite its many advantages, air conditioning can also negatively affect our health if not used responsibly. Here are the most common problems:
- Dryness of mucous membranes: Air conditioners reduce the humidity in the air, which can lead to dryness of the mucous membranes of the nose, throat and eyes. This manifests as scratchy throat, dry eyes and even nosebleeds.
- Colds and infections: Sudden temperature changes when entering and leaving air-conditioned rooms can weaken the immune system. Increasing the risk of colds and respiratory infections.
- Allergies and asthma: Improperly maintained air conditioners can harbor fungi, mold and bacteria that trigger allergic reactions and exacerbate asthma symptoms.
- Sick building syndrome: Prolonged exposure to air-conditioned spaces with improperly functioning ventilation can lead to what is known as sick building syndrome. Symptoms include headaches, fatigue, eye and respiratory irritation.
- Sinus problems: Dry air and temperature fluctuations can promote sinusitis.
How to use air conditioning so as not to harm your health?
To minimize the risk of negative effects of air conditioning, it is worth following the following rules:
- Maintain the right temperature: The temperature difference between the air-conditioned room and the environment should not exceed 5-7 degrees Celsius.
- Regularly clean and de-fumigate the air conditioner: Filters should be changed or cleaned according to the manufacturer’s recommendations. It is also a good idea to regularly de-fumigate the unit.
- Use air conditioning in moderation: Don’t overcool rooms. Try to regularly ventilate the rooms you are in.
- Ensure that the air is properly humidified: Use humidifiers or set up water dishes indoors.
- Avoid direct cool air: Do not direct the air supply directly at yourself.
- Check your health regularly: If you observe symptoms in yourself that may be related to air conditioning use, consult your doctor.
Air conditioning and specific risk groups
Some people are more sensitive to the negative effects of air conditioning:
- Allergists and asthmatics: They should pay special attention to the cleanliness of the air conditioner and change the filters regularly.
- People with respiratory diseases: Should avoid sudden temperature changes and dryness of mucous membranes.
- Elderly and children: They are more susceptible to overheating and dehydration, so it’s important to maintain the right temperature and humidity indoors.
Summary
Air conditioning can be a valuable ally in the fight against the heat, but it is important to use it judiciously. Observing hygiene rules and skillfully regulating the temperature will allow you to enjoy thermal comfort without harming your health.
