The Effects of Humidity on the Human Body. As discussed in Home Humidity and Allergies, humidity directly affects the amount of allergens in the indoor environment. In particular, high humidity causes both dust mite populations and mold colonies to grow, thereby greatly increasing allergy sufferers' total allergen load.
Relative humidity decreases as temperature increases. The importance of air temperature to moisture is obvious. At 80Â°, the air has a relatively low humidity and is relatively dry. As it cools, the humidity increases, reaching its saturation point at 40Â°. Now the air is very moist, and clouds will form.
