Indoor humidity is important to consider for both human health and the health of our homes. Too much humidity causes allergic reactions, triggers asthma and creates long term damage to structure and drywall to our homes. A dry house causes respiratory problems as well as cracks in floors and furniture.

The humidex is a valuable measure of the effect of humidity on how hot it feels. Since our body’s primary cooling mechanism is through perspiration and the cooling effect of evaporation from our skin; as the humidity increases, there is less evaporation and we feel hotter.
