The temperature reading depends on which part of the body is being measured. The typical daytime temperatures among healthy adults are as follows: Temperature in the rectum (rectal), vagina, or in the ear (tympanic) is about 37.5 °C (99.5 °F) [20] [medical citation needed] Temperature in the mouth (oral) is about 36.8 °C (98.2 °F) [12]
When environmental temperature is above core body temperature, sweating is the only physiological way for humans to lose heat. [10] Arteriolar vasodilation occurs. The smooth muscle walls of the arterioles relax allowing increased blood flow through the artery. This redirects blood into the superficial capillaries in the skin increasing heat ...
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 .
Temperature can be measured from the mouth, rectum, axilla (armpit), ear, or skin. Oral, rectal, and axillary temperature can be measured with either a glass or electronic thermometer. [ 11 ] Note that rectal temperature measures approximately 0.5 °C higher than oral temperature, and axillary temperature approximately 0.5 °C less than oral ...
For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...
A new color-coded heat warning system relies on magenta to alert Americans to the most dangerous conditions they may see this summer. The National Weather Service and the Centers for Disease ...
The human body is a collection of tissues with differing heat capacities, all connected by a dynamic circulatory system with variable relationship to skin or lung surfaces designed to shed heat energy. All methods of inducing higher temperature in the body are countered by the thermo-regulatory mechanisms of the body. The body as a whole relies ...
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 ...
