The topic Sweat Rash you are seeking is a synonym, or alternative name, or is closely related to the medical condition Heat Rash.

Quick Summary:

• Heat Rash, also known as Miliaria, is an itchy and slightly uncomfortable rash that occurs typically during hot-humid weather, due to excessive sweating. It is a commonly observed condition in children and adults
• The cause of Heat Rash typically occurs from blocked sweat glands arising from several factors such as tight clothing and intense physical activity. In this condition, there is an occlusion of the eccrine sweat glands
• Depending on their appearance, there are three forms of Heat Rash:
  • Miliaria crystallina: It involves the superficial layers of the skin (stratum corneum) and causes the production of clear vesicles without associated redness (erythema). It is the least severe form of Heat Rash
  • Miliaria rubra: The condition involves the deeper layers of the skin lining (epidermis) causing leakage of sweat and associated inflammation resulting in the formation of red papules. It is the most common form of Miliaria
  • Miliaria profunda, also known as tropical anhidrosis: It involves the deeper layers of skin (specifically, the dermo-epidermal junction). This form usually occurs after the individual has multiple recurrent episodes of Miliaria rubra. It is a rare condition that is often noted in adult males
• The signs and symptoms generally depend on the type of Heat Rash and may include the presence of small blisters or red bumps, itchiness, an absence of sweating, heat intolerance, and fever, in some cases
• Heat Rash is generally not a serious condition. It usually goes away without the need for any treatments. In a vast majority of cases, the prognosis is excellent, though rarely, this may also depend on the type of Heat Rash
