Heat exhaustion is a condition within the spectrum of heat-related illnesses ScienceDirect Article that can affect anyone, though it is particularly prevalent among children, older adults, and individuals with chronic diseases due to their reduced ability to dissipate heat effectively. It occurs when the body is unable to cool itself adequately after prolonged exposure to high temperatures or during intense physical activity, leading to symptoms such as fatigue, dizziness, headache, nausea, and vomiting. Dehydration DeGruyter Journal exacerbates the condition, as insufficient fluid intake impairs the body’s cooling mechanisms. If not promptly addressed, heat exhaustion can progress to heatstroke, a severe and potentially life-threatening condition characterized by extreme hyperthermia and central nervous system dysfunction. Management of heat exhaustion Human Kinetics Journal involves immediate cessation of physical activity, moving to a cooler environment, hydration, and cooling strategies such as removing excess clothing and applying wet towels. Preventive measures, including public awareness and proper hydration, are crucial in mitigating the risks associated with heat exhaustion.

Types of Heat exhaustion

Recognizing the distinct types of heat exhaustion can help in early identification and treatment, reducing the risk of progression to more severe heat-related illnesses. Whether it’s caused by water depletion or salt depletion, each type has unique symptoms and requires specific intervention strategies. Below, we explore the main types of heat exhaustion and their key characteristics.

• Exertional heatstroke (EHS)
• Hyperthermic exhaustion
• Heat edema
• Heat rash
• Heat cramps
• Heat syncope
• Severe heat exhaustion
