Summer Tips for Managing Indoor Humidity Levels

Indoor humidity levels

High indoor humidity levels can affect your comfort

Think we’re out of the “Dog Days of summer”? Think again. Farmers’ Almanac 2016 Summer Outlook predicts the peak of summer heat to occur between late August and early September. Not only are some U.S. regions already starting to experience the hottest temperatures of the year; they are feeling the effects of increased humidity.

“The hottest parts of the country, including Texas, the Southwest, and Florida have already experienced large increases in extreme heat days, including days over 90°F, 95°F, and 100°F, as well as rising levels of humidity that make hot days feel miserable and extremely hot days downright dangerous.” (Source:

Effects of High Indoor Humidity Levels


Soaring summer heat can put a damper on outdoor activities but excessive humidity can also creep into your home and affect your comfort, your health, and your property. High indoor humidity levels can make you feel overheated. Then, when you lower your thermostat temperature, your utility bills can go through the roof. That’s because the damp, muggy feeling can cause you to feel warmer.

Example:  If the air temperature is 75°F and the relative humidity is zero percent, then our body perceives the air temperature to feel more like 69°F.  Now if the air temperature is 75°F degrees and the relative humidity is 100 percent, then it will feel closer to 80°F.  (Source:

Too much home humidity can also create a breeding ground for mold and bacteria that can decrease air quality, aggravating allergy or asthma symptoms. (Learn about  “Tips to Improve Indoor Air Quality”.) Excessive moisture in the air can also be the source of a myriad of problems with your home’s furnishings and even cause structural damage.

Here are some other issues caused by high indoor humidity levels:

  • Poor quality of sleep
  • Doors and windows stick
  • Dust mites
  • Wilted plants
  • Smelly plants
  • Peeling paint or wallpaper

So what is the best indoor humidity for your home and how can you manage it? Most experts say that the ideal house humidity should be between 30 and 50 percent, but definitely below 60 percent in the summer months.

Tips for Managing Home Humidity


One of the easiest ways to conserve energy while also retaining and maximizing home comfort levels is to use your Sensi™ Wi-Fi Programmable Thermostat settings and schedules. Your Sensi mobile app also displays your indoor humidity levels and sends you a High Humidity alert when your home humidity is greater than 78% so you can take steps to manage using the above tips or by calling your local HVAC contractor to check on your equipment.
