Heat-Related Overexertion

Heat-related overexertion occurs when the body is unable to cool itself efficiently, leading to various symptoms ranging from mild discomfort to severe medical emergencies. In this guide, we’ll break down the types, causes, symptoms, diagnostic tests, treatments, drugs, and potential surgeries related to heat-related overexertion in simple, accessible language.

Types:

  1. Heat Cramps: Painful muscle contractions caused by dehydration and electrolyte imbalances.
