Final Answer:
The condition is known as "miliaria" or more commonly, "heat rash."
Step-by-step explanation:
Excessive heat exposure can lead to a condition known as miliaria, or more colloquially, heat rash. This occurs when sweat ducts become blocked, trapping sweat beneath the skin. The trapped sweat causes inflammation, leading to the characteristic red rash and discomfort associated with heat rash.
In miliaria, the sweat glands, responsible for regulating body temperature, become overwhelmed due to prolonged exposure to high temperatures. When the sweat ducts are obstructed, the sweat is unable to reach the surface of the skin and gets trapped beneath, causing irritation and inflammation. This inflammatory response manifests as red, itchy bumps on the skin, which is the hallmark of heat rash.
Preventing heat rash involves staying cool in hot environments, wearing breathable fabrics, and avoiding activities that lead to excessive sweating. Additionally, maintaining good hygiene helps prevent the buildup of sweat and bacteria on the skin, reducing the risk of sweat duct blockage. Understanding the causes and preventive measures is crucial for managing and mitigating the effects of heat rash, a common condition in hot and humid climates.
