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.
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]
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]
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 ...
A 2022 study on the effect of heat on young people found that the critical wet-bulb temperature at which heat stress can no longer be compensated, T wb,crit, in young, healthy adults performing tasks at modest metabolic rates mimicking basic activities of daily life was much lower than the 35 °C (95 °F) usually assumed, at about 30.55 °C (86 ...
Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F). [3] [4] Humans have adapted to living in climates where hypothermia and hyperthermia were common primarily through culture and technology, such as the use of clothing and shelter. [5]
Malignant hyperthermia; Other names: Malignant hyperpyrexia, anesthesia related hyperthermia [1] Abnormalities in the ryanodine receptor 1 gene are commonly detected in people who have experienced an episode of malignant hyperthermia: Specialty: Anesthesiology, critical care medicine: Symptoms: Muscle rigidity, high body temperature, fast heart ...
Human herpes viruses are a common cause of fever of unknown origin with one study showing Cytomegalovirus, Epstein–Barr virus, human herpesvirus 6 , human herpesvirus 7 being present in 15%, 10%, 14% and 4.8% respectively with 10% of people presenting with co-infection (infection with two or more human herpes viruses).
