Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F), [4] along with red skin, headache, dizziness, and confusion. [2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...
Heat stroke - Defined by a body temperature of greater than 40 °C (104 °F) due to environmental heat exposure with lack of thermoregulation. Symptoms include dry skin, rapid, strong pulse and dizziness. [7] Heat exhaustion - Can be a precursor of heatstroke; the symptoms include heavy sweating, rapid breathing and a fast, weak pulse.
Thus, aggressive ice-water immersion remains the gold standard for life-threatening heat stroke. [31] [32] When the body temperature reaches about 40 °C (104 °F), or if the affected person is unconscious or showing signs of confusion, hyperthermia is considered a medical emergency that requires
Heat stroke is defined by two key features: a core body temperature above 40 °C (104 °F) and central nervous system dysfunction. In classic heat stroke, sweating ceases due to sweat gland dysfunction or depletion. This loss of evaporative cooling further accelerates heat accumulation.

If this is insufficient, hyperthermia will set in, body temperature may reach 40 °C (104 °F), and heat stroke may occur. In a cold environment, shivering will start, involuntarily forcing the muscles to work and increasing the heat production by up to a factor of 10. If equilibrium is not restored, hypothermia can set in, which can be fatal. [55]

Heat stress can result in heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps, heat rashes, and chronic kidney disease (CKD). [2] [3] Although heat exhaustion is less severe, heat stroke is a medical emergency and requires emergency treatment, which if not provided, can lead to death. [4]
