<unk>  related illnesses includes a wide range<unk>  from benign<unk>  rash to<unk>  stroke.
Dehydration and salt depletion affect thermoregulation by reducing the body's ability to increase the cardiac output needed to dissipate the<unk> ed blood
Cardiovascular disease and use of drugs that impair cardiac function can result in increased susceptibility to<unk>  illness
Conduction:<unk>  exchange between two surfaces in contact (placing ice pack in axilla)
Convection:<unk>  exchange between a surface and a fluid (fanning)
Radiation: transfer of<unk>  between body and environment through electromagnetic waves (reliant on temperature gradient)
All types are due to inadequate thermoregulation
