Overview

About this course

Heat-related illnesses encompass a spectrum of conditions caused by the body’s inability to regulate temperature during excessive heat exposure. These range from mild cases, such as heat rash and heat cramps, to moderate conditions like heat exhaustion, and can progress to severe, life-threatening heat stroke. Rising global temperatures have led to a 54% increase in heat-related deaths over the past two decades, making early recognition and intervention critical.

Certain populations, including the elderly, children, outdoor workers, and athletes, are at higher risk of experiencing heat-related illness. Among the heat-related illnesses, heat stroke is of particular concern as it is a medical emergency which requires immediate attention. Heat stroke symptoms include confusion, seizures, and loss of consciousness, while early signs of heat fatigue, such as dizziness and muscle weakness, may indicate worsening illness. Diagnosis is primarily clinical, with laboratory tests performed in cases of suspected organ dysfunction or electrolyte imbalance.

Management of heat-related illnesses focus on removing the patient from heat, cooling the body, rehydration, and close monitoring. Preventing heat-related illness requires identifying at-risk individuals, promoting proper hydration, and educating communities on early symptoms. Implementing preventive measures and timely interventions can significantly reduce morbidity and mortality.

This e-learning module aims to deepen primary care physicians’ understanding of heat-related illness, equipping them with essential knowledge to improve patient outcomes and reduce heat-related health risks.
