Nobody likes it when the humidity rises on a hot summer day, because we know what that feels like—a much hotter day. The truth is that high humidity doesn’t raise the temperature of the air. What it does is make it harder for our bodies to release heat through our skin. More heat is trapped in our bodies, and so we feel even hotter. Think of humidity as like throwing a blanket around your body on a hot day. Not something you would want to do.
“Yeah, humidity is rough in summer,” you say, “but I’ve got my air conditioner to handle it.”
