[2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...
This sobering statistic underscores a 117 percent surge in heat-related deaths since 1999, with over 20,000 lives claimed by blistering temperatures over the past two decades.
Heat waves are often followed by a rise in the death rate, and these 'classical hyperthermia' deaths typically involve the elderly and infirm.

Heat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion.It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. [1]
