When the weather is hot, it is important to keep your body well hydrated and as cool as possible. Sweating is one way that your body helps cool itself down naturally. The Centers for Disease Control and Prevention explains that excess sweating during hot, humid weather can lead to conditions such as heat rash. Keeping your skin dry in humidity, especially your underarms, groin, chest, neck and skin folds, will help keep your skin healthy and prevent uncomfortable skin conditions.
Turn on a fan, which will help circulate the humid air and help keep you dry. If you have an air conditioner, it will also keep your skin dry since it both cools and dehumidifies the air.
Apply talcum powder to your skin to keep it dry when the weather is humid. A thin layer of powder, applied with a powder puff or your hands, can help keep your skin dry in humidity and kill yeast that can cause skin infections.
Keep the skin under your arms dry in humid weather using an underarm deodorant that contains an antiperspirant. Antiperspirants contain active ingredients such as aluminum chloride or aluminum hydroxybromide, which close the pores and prevent sweating.
Wear loose-fitting, lightweight clothing on humid days. Cotton fabrics that flow away from your body, instead of clinging to it, can help keep your skin dry.
