Humidity is described as the water vapor levels that are in the air that we breathe. When the air warms up, the vapor levels drop. As the air becomes heavy with rain, the levels begin to rise. Either of these extremes causes us to become uncomfortable and more susceptible to illnesses.



In the winter, the humidity levels tend to be low due to continued use of furnaces and other heating devices. When this happens, we are left with dry skin, lips and eyes, which are uncomfortable, but can be dealt with. However, for some people, especially the very young, very old or those already compromised by sickness, the dryer air can leave them more susceptible to respiratory issues such as bronchitis and asthma.

The use of a home humidifier will bring the air moisture levels to where they need to be. There are several types of humidifiers to choose. A popular type of devise works by warming up water from a reservoir tank, the evaporated water is then dispersed through the home with the use of a fan system. Another system utilizes a continuous mist or steam that is dispersed through the whole house, putting the needed moisture into the air.

A dehumidifier addresses the opposite problem. When the air that we breathe becomes saturated with water, we become uncomfortable, the air is sticky and it is harder to breath. The most common way to deal with this problem is with the use of an air conditioner, which literally sucks the water from the air. This effectively lowers the moisture levels and makes us more comfortable.

If an air conditioner is not an option, the next most common way to control high humidity levels is with the use of a bathroom or kitchen exhaust fan; these are the two places where high humidity levels are frequently found. The exhaust fan pulls the high moisture air out of the room, resulting in a more normal air/water level.

Another way to dehumidify the air in a house is with a dehumidifier. The use of a dehumidifier becomes important in areas of the house that never seem to dry out, such as the basement; or if someone in the home has allergies to mold. Most molds are very common and are not anything to worry about, except in the case of an allergy sufferer. In this case, a dehumidifier should be used in the bedrooms of the person with allergies as well as in or around the high humidity areas of the home.

Humidifiers and dehumidifiers can be found in a size that is right for every house, in fact for every room of the house. They are sold in a variety of stores from home improvement stores to discount chains, from drugstores to online vendors. If you are unsure if the use of a humidifier or dehumidifier is what is needed for your health issues, talk with your doctor, he or she will let you know if the use of one of these devises will alleviate your symptoms.
