High humidity affects indoor comfort primarily by making temperatures feel warmer than they actually are. When the air is saturated with moisture, it becomes more difficult for sweat to evaporate from the skin, which is the body’s natural cooling mechanism. As a result, individuals may feel hotter and more uncomfortable even if the actual temperature is not excessively high. This phenomenon is often measured using the heat index, which combines air temperature and humidity to give an accurate representation of how hot it feels.

While some may think that high humidity could cool down a space or stabilize temperature fluctuations, these points do not accurately reflect the impact of humidity on comfort. Additionally, high humidity levels can detract from air quality by promoting the growth of mold and dust mites, which can lead to respiratory issues. Thus, the essence lies in how humidity influences the body’s ability to regulate temperature, leading to a perception of increased warmth.
