The Health and Environmental Benefits of Dehumidifiers

If you live in a humid climate or environment you would do well to invest in a dehumidifier.

Not only do they make a living or work space more comfortable for people to be in - a comfortable humidity level for most of us is around 30% - but there are health and environmental benefits too.

For one thing they help to inhibit the production of mold and mildew which thrive on moisture. Mold spores can affect people with breathing difficulties and may produce an allergic reaction with sensitive individuals. These can be an itchy, runny nose and sneezing also known as "allergic rhinitis." or possibly induce an asthma attack on those affected with allergic asthma.

In 1991 the American Journal of Epidemiology reported a study carried out on the health effects of the home environment which concluded that:

"Prevalences of all respiratory symptoms were consistently higher in homes with reported molds or dampness"

Mold feeds on materials which are commonplace around the house such as wood, textiles and wallpaper. They also feed on dead skin cells.

It is particularly important to have a dehumidifier in a damp area with poor ventilation, as is often the case with a basement, as the moisture cannot evaporate so easily. Modern buildings are much more airtight than older ones. This is because synthetic rather than natural building materials are used and the buildings "breathe" less and so cannot expel their moisture through ventilation.

The water which accumulates in a dehumidifier called the condensate, while not suitable for drinking can be used to water non-food plants or to rinse off the car windshield.

There are a variety of pests that thrive in damp conditions, for example fleas, clothes moths, cockroaches and dust mites. Cockroaches can themselves be hazardous to human health as they carry a protein called tropomyosin which can trigger an allergic reaction in asthmatics. They also eat human and animal food, and give off an unpleasant smell. Using a dehumidifier will deter them.

Buildings are liable to decay if they get too damp. The mold eats away at the fabric of the building causing it to weaken, and as it does it produces toxins (mycotoxins) which are harmful to health.

Additionally, a building with too high a humidity level can feel oppressive and it can be an effort to just go about your regular business, and a room with mold has an unpleasant musty smell.

Having a dehumidifier in an overly damp place creates a more healthy environment and makes the place feel and smell fresher. They are good for people and good for buildings.
