3. Skin Problems

Air conditioners have a dehumidifying effect in the room. In order to cool the room temperature, it draws the room air into the evaporator coil. In this process, the moistures in the room also get sucked away. Thus an air-conditioned room lacks moisture, which causes dry skin and nasal passage. In winter, this problem only intensifies. If you are exposed to air conditioners for a long time, you should take the necessary actions to prevent these problems. Constantly applying a preferred moisturizer is a good solution to this problem.

4. Decreased Heat Tolerance

Constant exposure to air condition decreases the heat tolerance level. None of us likes extreme heat, but if you start feeling uncomfortable shortly after you go outside in hot summer days, then your heat tolerance level has gone down. Absorbing natural heat to some extent is healthy and recommended. If your office or resident is constantly air conditioned, it is a good idea to turn off the unit for a while if possible or get some fresh air from time to time.

5. Overweight Problem

There is no doubt that air conditioners make us comfortable. It has been found that in air-conditioned rooms, people move or exercise less because of the comfortable temperature. This makes our body burn fewer calories when compared to the normal conditions. Another fact is that in hotter temperature people tend to eat less. On the contrary, in cool temperature people tend to eat more. So if you want to lose some weight, it might be a good idea to exercise after turning off the AC.

Cool temperature plays a role in increasing resistance in our arteries and raising the blood pressure. People suffering from high blood pressure, are recommended to limit down their exposure to air conditions at a bare minimum.

Another common question in this regard is, is it cheaper to leave air conditioner on all day? Many would say yes. The logic behind this argument that, by keeping it on all day and night, air conditioners require less energy to provide the desired temperature. Although it might sound convincing, it is wrong. It is not an effective way to run the air conditioner all day & night. The appropriate solution, in this case, would be, installing a programmable thermostat. This would enable you to program your desired temperature. By installing a programmable thermostat, you can program your ac to change the temperature automatically. For example, at night the temperature of the outside decrease automatically. With a programmable thermostat, you can save yourself from the freezing cold in the morning.

If we carefully consider the health issues and the cost and environmental issues of the air conditioner running all day, we can easily conclude that although air conditioners provide effective cooling, but it is not safe to run them all day and night. You can consider other cooling options, like an evaporative air cooler before you buy an air conditioner. The best option is to have them both because this way, you can get the best possible cooling option with a reasonable operating cost. It would offer you flexibility and reduce the health risks of longtime air conditioner exposure.
