 Explanation: 
Detailed explanation-1: -Temperature-Decreasing Mechanisms When the body core temperature rises above the critical level of 37 C (98.6 F), there is an increase in the rate of heat loss by sweating. Shivering and chemical thermogenesis are strongly inhibited.
Detailed explanation-2: -When the ambient temperature exceeds body temperature, heat is taken in from the environment. As soon as body temperature increases above the thermoregulatory set-point, heat dissipation depends on both autonomic and behavioural adjustments.
Detailed explanation-3: -Heat fatigue, heat syncope (sudden dizziness after prolonged exposure to the heat), heat cramps, heat exhaustion and heat stroke are commonly known forms of hyperthermia.
