How Does Humidity Affect Temperature? [Simple Guide]

Oct 28, 2018· No matter what time of year it is or what indoor and outdoor temperature is, your humidity levels should stay between 30 to 50 percent. If your indoor humidity levels are low or less than 30 percent, it'll get too dry in your home, and this is called dry air. When this occurs, dry air results in dry skin, nosebleeds, and sore throats.
