Minor Heat Illnesses

Abstract

A large number of medical conditions fall under the umbrella term of “heat illnesses.” While these conditions span across a spectrum relative to severity, these heat illnesses are in fact independent medical conditions. More severe conditions are discussed in more detail in other chapters within this text. The goal of this chapter is to highlight the pathophysiology, recognition, treatment, and return to activity of several minor conditions that result from heat exposure. These conditions may contribute to the risk for developing more severe heat illnesses, making the understanding of these minor heat illnesses and prevention important. Preventing minor heat illnesses can reduce the risk of developing more severe exertional heat illnesses and can enhance safety and performance during exercise and physical activity in the heat.
