The disorder caused by exposure to excessive heat that usually clears quickly without treatment is commonly known as heat rash. This condition occurs when sweat can’t evaporate efficiently due to blocked sweat ducts, leading to small red bumps or blisters on the skin. Heat rash is most often seen in hot, humid weather and typically resolves on its own once the individual returns to a cooler environment or reduces sweating.

The mention of "Millibars rubra" suggests some confusion with the term "miliaria rubra," which is the medical term for heat rash. It's important to be aware that although chronic dermatitis and pityriasis are skin conditions, they are not specifically linked to excessive heat and do not resolve as rapidly. Chronic dermatitis is a long-term inflammatory condition, while pityriasis refers to a range of skin disorders, none of which are characterized by the immediate and self-resolving nature of heat rash. Understanding these distinctions is key when identifying skin disorders related to the sudoriferous glands.
