We know about “muggy’. We know about “sticky’. But how do these uncomfortable air conditions develop’ Humidity is the moisture in the air, and it affects how we perceive the temperature. It also affects indoor air quality by fostering mold and mildew growth, or restricting it. Humid air helps mold and mildew to grow, whereas drier air does not.

Warm air can hold more moisture than cold air; so more humid or “sticky” days occur during the summer months in North America. For most people, a relative humidity of 45 to 55% is comfortable. As this value rises, the air becomes more uncomfortable and “muggy’.

States and locations near large bodies of water will be more humid. Homes near the Great Lakes or large rivers, or near the ocean will be greatly affected by humidity levels. Even homes or cabins near large inland lakes need dehumidification during the summer months.

Understanding the Dew Point

Meteorologists talk about the dew point . This is the temperature at which the air becomes saturated with moisture, causing dew droplets to form. As a general rule, the closer the dew point is to the actual temperature, the higher the humidity level and the more uncomfortable it will feel.

You can follow the dew point on the Weather Channel or other weather apps, and pretty well predict if the day will be comfortable or uncomfortable from a humidity stand point. You can determine whether you need to run your air conditioning or not, and whether you need to run your dehumidifiers. Whether this is a good day for gardening, golfing, the beach, or just hibernating indoors!

Dewpoints below 55 are very comfortable for most people

56 ” 60 “Still pretty comfortable

61 ” 65 “Starting to get “sticky’

66 ” 70 “Starting to really feel “muggy” now, and quite uncomfortable

You can measure the relative humidity in your home using the handy hygrometer from Eva-Dry. Again keeping in mind that 45-55% humidity is comfortable for most people, you can control the indoor humidity with the use of air conditioning or dehumidifiers. And remember: relative humidity above 55% will foster the growth of mold spores, dust mites and bacteria, aggravating the symptoms of allergy sufferers and those with respiratory problems. So keeping the humidity down helps to improve the indoor air quality in your home as well as keeping your family more comfortable.
