Summers in Louisiana bring both heat and humidity—and everyone knows this is an unpleasant combo! No matter how hot it is, a high level of humidity will make the heat feel worse. This is because the moisture in the air makes it harder for the human body to release heat through perspiration. With more heat trapped in the body, people feel even hotter than the air around them.
Since we frequently experience relative humidity above 80% during the summer (which is already 20% above what’s considered comfortable), we have an uphill battle cooling down our homes. Air conditioners must run more often to overcome the effects of both the heat and humidity, and this creates higher energy bills. The extra humidity is also harmful to furnishings in a home and allows mold, mildew, and fungus to start to grow.
