Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system .
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
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]
Stephanie Miller, a safety and health manager for a U.S. government contractor doing cleanup work at the Oak Ridge National Laboratory, watched a computer screen nearby. Sensors can read your ...
Overheating may refer to: Overheating (economics) , a rapid, very big growth of production that is thought to have a negative influence Overheating (electricity) , unexpected rise of temperature in a portion of electrical circuit, that can cause harm to the circuit, and accidents
Signs of heat exhaustion include fatigue, headache, and dizziness. Nausea and muscle cramps may indicate you've sweat out essential electrolytes. 5 subtle signs you're overheating and at risk of ...
This occurs at accelerated life tests or high temperatures and is suspected to be caused by surface-state effects. Degradation in pinch-off voltage. This is a common failure mode for gallium arsenide devices operating at high temperature, and primarily stems from semiconductor-metal interactions and degradation of gate metal structures, with ...
Allen's rule is a biological rule that says the limbs of endotherms are shorter in cold climates and longer in hot climates. Limb length affects the body's surface area, which helps with thermoregulation. Shorter limbs help to conserve heat, while longer limbs help to dissipate heat. [13]
