Human responses to heat stress can include heat stroke and overheating (hyperthermia). Extreme heat is also linked to acute kidney injury, low quality sleep, [21] [22] and complications with pregnancy. [23]: 1051 Furthermore, it may cause the deterioration of pre-existing cardiovascular and respiratory disease.
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]
Thermal work limit (TWL) is an index defined as the maximum sustainable metabolic rate that well-hydrated, acclimatized individuals can maintain in a specific thermal environment within a safe deep body core temperature (< 38.2 °C or 100.8 °F) and sweat rate (< 1.2 kg or 2.6 lb per hour). [1]

On NOAA's HeatRisk tool, the scale ranges from 0 or green, meaning little or no risk from expected heat, to 4 or magenta, which indicates extreme and/or long-duration heat-related impacts.
The National Weather Service and the Centers for Disease Control and Prevention on Monday — Earth Day — presented a new online heat risk system that combines meteorological and medical risk ...
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 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]
