Miliaria or sweat rash, on the other hand, is a skin disease marked by small and itchy rashes which is common in hot and humid conditions. It occurs when the sweat gland ducts get plugged due to dead skin cells or bacteria. The trapped sweat leads to irritation, itching and to a rash of very small blisters, usually in a localized area of the skin.
