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).
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [2] as blood vessels dilate in an attempt to increase heat loss.
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] It can affect any or all anatomical systems. [2]

"When heat stroke occurs, the body is unable to regulate its own temperature and body temperatures can climb to 106 degrees, leading to brain damage, and if left untreated, death," Zaslow says.
Rising body temperatures and a drop in blood pressure are where Lichfield said heat exhaustion turns into stroke, a dangerous situation where organs begin to fail and can rapidly lead to death.
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 exhaustion is marked by cold, pale, clammy skin, as well as heavy sweating, fainting, vomiting, dizziness, headache, nausea and weakness. More: Left in a hot car for 4 hours: Monticello woman ...
