When muscle tissue dies, electrolytes and large proteins are released into the bloodstream. As greenhouse gas concentrations continue to rise, infra-red radiative cooling by the surface and the atmosphere (1) to space becomes less effective. quantity of heat energy lost by radiation Sweating is not a good sign of heat stress as there are two types of heat stroke non-exertional or "classical" where there is little or no sweating (usually occurs in children, persons who are chronically ill, and the elderly), and "exertional" where body temperature rises because of strenuous exercise or work, and sweating is usually present..
