Question

why is it necessary to give heat shock at 42 degrees not furthur temperature

Answer 1

Hypothermia is reduced body temperature that happens when a body dissipates more heat than it absorbs. In humans, it is defined as a body core temperature below 35.0 °C (95.0 °F).[2] Symptoms depend on the temperature.[2] In mild hypothermia there is shivering and mental confusion.[2] In moderate hypothermia shivering stops and confusion increases.[2] In severe hypothermia, there may be paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping.
