Deaths. > 600 per year (US) [4] 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]
Heat exhaustion is a heat-related illness characterized by the body's inability to effectively cool itself, typically occurring in high ambient temperatures or during intense physical exertion. In heat exhaustion, core body temperature ranges from 37 °C to 40 °C (98.6 °F to 104 °F). Symptoms include profuse sweating, weakness, dizziness ...
Human responses to heat stress can include heat stroke and hyperthermia. Extreme heat is also linked to low quality sleep, acute kidney injury [21] [22] and complications with pregnancy. Furthermore, it may cause the deterioration of pre-existing cardiovascular and respiratory disease.
This chart shows that population each day during the last month. As the planet warms, heat waves are now more common, intense and long-lasting, and temperatures are warming even faster overnight ...
Heat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion.

In the case of heat stroke, experts suggest calling 911 and trying to lower the person's body temperature with cool, wet cloths or a cool bath. With heat exhaustion, the body can become cold and ...
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [3][10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [2] Hyperthermia requires an elevation from ...
