During the winter months, as the combination of cold air and overheated homes dries out the skin, humidifiers can boost much-needed moisture, emitting water vapor into the air. That moisture helps alleviate dry skin, chapped lips, nose bleeds, and other cold-weather conditions. Although fewer people think to use them during the summer months, humidifiers aren’t just for the wintertime, explained Jessie Cheung, MD, a board-certified dermatologist. “Moist air helps slow down the transmission of microbes and can combat the dry air from summer air conditioning,” she said. “It also allows for more comfortable breathing if you have blocked sinuses or respiratory infection and helps to keep sensitive skin from drying out.” Therefore, investing in a humidifier gives you year-round benefits.
