High humidity is a problem that most people don’t need explained to them. Even if they don’t know why high humidity on a hot day makes the hot day feel much worse, they know exactly what the sensation is like. With too much moisture in the air (relative humidity higher than 60%), the human body cannot release heat as effectively and the trapped heat causes temperatures to feel hotter than they are.
But what about low humidity? You’ve heard the phrase “a dry heat” as a positive, but dryness itself is not positive and is as much trouble as high humidity. Dry conditions often occur during the winter, and your house might benefit from a whole-house humidifier to provide the balance necessary for comfort and health.
