In short, yes. Humidity has a pretty large impact on how comfortable you feel. Your body is very good at regulating temperature and sweat is one of the ways it does that. This doesn’t mean that humidity is only important when you’re hot enough to sweat. High humidity makes you feel warm and clammy. Reducing humidity can make you feel 2 or 3 degrees cooler when the thermostat is set to exactly the same temperature. Not only do you feel more comfortable but you also save money if your thermostat can be set a little higher.
