Other rare causes of hyperthermia include thyrotoxicosis and an adrenal gland tumor, called pheochromocytoma, both of which can cause increased heat production. [2] Damage to the central nervous system from brain hemorrhage, traumatic brain injury, status epilepticus, and other kinds of injury to the hypothalamus can also cause hyperthermia. [2]
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]
The incidence of heat stroke is higher among men; however, the incidence of other heat illnesses is higher among women. [29] The incidence of other heat illnesses in women compared with men ranged from 1.30 to 2.89 per 1000 person-years versus 0.98 to 1.98 per 1000 person-years. [29]
Space heaters also have a hidden hazard: They can cause overheating — aka hyperthermia — especially in kids, people with disabilities and older adults who may have difficulty leaving a room ...
The cause of postmortem caloricity varies depending on the cause of death: Postmortem glycogenolysis – a phenomenon beginning soon after death observed in nearly all cadavers. In an average adult, postmortem glycogenolysis can produce up to 140 calories of heat which can raise the temperature of the body by up to 2 °C.
This loss of evaporative cooling further accelerates heat accumulation. The resulting hyperthermia leads to widespread cellular dysfunction, including: [10] [11] [12] [15] Alterations in enzyme function; Protein denaturation; Disruption of cellular membranes. Hyperthermia causes direct cellular damage, triggering a systemic inflammatory response.
Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).
Physical activity in extremely hot weather should be avoided. If a person starts to experience over heating, and symptoms of heat syncope, they should move or be moved to a shaded or cool area. It is also recommended to avoid alcoholic beverages in hot weather, because they cause dehydration which may worsen symptoms.
