Meteorologists often use the relative humidity as a measurement to describe the weather at various places. When the temperature is warm, more water vapor can be in the air than when it is cold. The effects of humidity can have a major impact on the way you feel. Use our relative humidity charts to find the proper humidity level in your house. The American Society of Heating Refrigeration, Air Conditioning Engineers recommends keeping your home between 40-60 percent. This is the optimal level of health and comfort. Put simply, relative humidity (RH) is a measure of the water vapor content of air.

Relative humidity

The term relative humidity (RH) expresses the relationship between the moisture content of air at Some of the ways low relative humidity affect your home include: Shrinking wood furniture, door, and window frames Hardwood floor separation and warping Peeling wallpaper Gaps between the walls and ceiling Relative humidity is an important metric used in weather forecasts and reports, as it is an indicator of the likelihood of precipitation, dew, or fog. In hot summer weather, a rise in relative humidity increases the apparent temperature to humans (and other animals) by hindering the evaporation of perspiration from the skin. Relative humidity (RH) is the actual amount of water vapor present in relation to the capacity that the air has at a particular temperature. While it is a bit misleading, think of the capacity as the amount of water vapor that the air can “hold”, though it is actually incapable of physically holding onto the water vapor (it moves too fast).

A relative humidity (RH) of 40-60% is generally considered to be optimal for a comfortable and healthy home. Too much moisture can lead to mold and overheating. Too little causes dry eyes, chapped lips and an environment in which bacteria and viruses can thrive. Fluctuations in indoor RH are caused by the following factors: 2014-02-28 The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount. We can use evaporation to measure the amount of moisture in the air.

During these church services, we observed that the humidity levels would spike to over 75%! In the end, we advised whenever possible to use dehumidifiers to reduce the humidity to acceptable levels.
