Some people sweat in amounts greater than needed to cool the body, a condition called Hyperhidrosis. Hyperhidrosis usually affects the palms of the hands, soles of the feet and underarms. Besides disrupting normal daily activities, hyperhidrosis can cause social anxiety or embarrassment.
The cause of hyperhidrosis stems from your body’s temperature regulation system, specifically your sweat glands.
Fungal Nail infections.
People who sweat profusely are prone to many types of fungal infections. That’s because fungi thrive in warm, moist environments, such as sweaty shoes. A nail infection usually begins as a white or yellow spot under the tip of your nail. As the fungal infection spreads deeper, your nail may discolor, thicken and develop crumbling edges. Sometimes your nail may separate from the nail bed, and the skin around it may become red and swollen. You may even detect a slight odor.
Bacterial Infections and Warts.
Hyperhidrosis can contribute to bacterial infections, especially around hair follicles or between your toes. It’s also associated with warts. When you have hyperhidrosis, warts may take a while to go away after treatment and they have a tendency to recur.
Other skin conditions. Certain skin conditions, such as eczema and skin rashes, occur more frequently in people with hyperhidrosis. It may be that excessive sweating exacerbates skin inflammation.
