Hot Topic: Exploring the Science of Heat Stress




Heat stress, also called hyperthermia disorders or heat-related illnesses, includes a spectrum of medical conditions that can occur when the body is exposed to excessive heat. These conditions range from mild issues such as heat cramps to severe, potentially life-threatening conditions such as heat stroke, resulting from the body’s inability to regulate its temperature. 1



Heat stroke is a severe heat-related condition where the body temperature can soar, typically exceeding 40°C. It causes symptoms like confusion, lack of coordination, delirium, or seizures. Heat stroke can be brought on by intense physical activity or exposure to hot weather, although not always. Heat stroke cases require immediate medical attention as it could be critical, especially among older individuals or in people with other health complications. 2
