6 Effects of Air Conditioning On Your Health

Next, we’ll take a look at the main negative effects of air conditioning on your health.

1. Respiratory Problems

It’s important to realize that any drastic change in temperature does damage to your respiratory system. Therefore, moving from a warm temperature to the cold temperature of the office or the supermarket can cause some real problems.

Because of the circulation of the air, it also makes you more vulnerable to respiratory infections. It can cause problems such as pharyngitis or throat infections.

In fact, there is evidence to suggest that people who spend more time in air-conditioned environments have a greater risk of developing throat and nasal symptoms. Therefore, they have a greater chance of developing nasal instructions like rhinitis.

2. Viral Infections

One very common effect of air conditioning is the spread of viral infections owing to a weakened immune system.

In an air-conditioned environment, the old air is constantly recirculated, stopping fresh air from getting in. As a result, the old air flows and transmits cold and flu germs, as well as other bacteria, from person to person.

Therefore, there is a greater risk of contracting a viral infection in an air-conditioned environment than in a room without air conditioning.

3. Dehydration

People who spend long hours in air-conditioned rooms are obviously more prone to dehydration. Since the air conditioning absorbs too much moisture, and people often don’t drink enough water, they become dehydrated.

This is possible even though the temperature is cooler because the body doesn’t feel hot and therefore is not as thirsty. Furthermore, being in a cooler environment means the body feels the need to move less.

4. Headaches

Without a doubt, headaches are one of the most common side effects of air conditioning. Certainly, if you abuse the air conditioning you can easily trigger a headache or even migraine when the air quality inside improves.

Obviously, the risk of being dehydrated also increases the chance of a headache. Dehydration is often ignored despite being a trigger for other health problems.

5. Dry Eyes
