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 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]
Most commonly males are brought in 72.5% and persons 15–19 years of age 35.6% [20] When taking into consideration all high school athletes, heat illness occurs at a rate of 1.2 per 100,000 kids. [21] When comparing risk by sport, Football was 11.4 times more likely than all other sports combined to be exposed to an exertional heat illness. [21]
In a study published in Arthritis & Rheumatology, researchers found the number one predictor of widespread pain, especially among adults over 50, is non-restorative sleep, or disruptive sleep ...
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 ...
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).
Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system.Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis, and hyperthermia. [1]
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 ...
