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 .
Commonly caused by excessive drying of the skin, eczema can grow worse in the summer as people are jumping into and out of chlorinated pools, showering frequently, and becoming dehydrated. Lips ...
A heated blanket or heating pad might keep you warm in the cold winter months, but experts are warning of a potential danger. Too much close exposure to high heat can cause noticeable skin damage ...
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] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...
This prevents blood from losing heat to the surroundings and also prevents the core temperature dropping further. This process is called vasoconstriction. It is impossible to prevent all heat loss from the blood, only to reduce it. In extremely cold conditions, excessive vasoconstriction leads to numbness and pale skin.
Heat exhaustion can be treated by moving to a cool place, drinking fluids, and applying cool compresses to the skin. Heat stroke It occurs when the body's temperature rises to dangerously high ...
In heat exhaustion, the core body temperature rises to between 37 °C and 40 °C (98.6 °F and 104 °F). To dissipate heat, blood flow to the skin can increase up to 8 liters per minute, accounting for a significant proportion of the cardiac output. This increase in peripheral circulation leads to a reduction in central blood volume—the ...
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]
