What is humidity? Humidity in the home is a concern during the damp rainy season. Humidity refers to water vapor contained in the air. Air can hold more water vapor at higher temperatures, so humidity tends to be higher during warmer periods. Furthermore, in homes, humidity tends to accumulate not only in warm areas but also in places with poor air circulation. Areas with poor ventilation, such as closets, wardrobes, and corners of rooms, require particular attention.
