PATHOLOGY

Detailed explanation-1: -If it heats up to 39-40C, the brain tells the muscles to slow down and fatigue sets in. At 40-41C, heat exhaustion is likely-and above 41C, the body starts to shut down. Chemical processes start to be affected, the cells inside the body deteriorate and there is a risk of multiple organ failure.

Detailed explanation-2: -Heat stroke can occur when your body temperature reaches above 104°F (40°C). Fainting is often the first sign. Other signs and symptoms include: irritability.

Detailed explanation-3: -Conversely, if the temperature falls below the set core temperature, the hypothalamus can initiate shivering to generate heat. The body uses more energy and generates more heat. In addition, thyroid hormone will stimulate more energy use and heat production by cells throughout the body.

Detailed explanation-4: -Hyperpyrexia is the term applied to the febrile state when the temperature exceeds 41.1°C (or 106°F).
