What is the relationship between sweating and body temperature?
When heat activates sweat glands, these glands bring that water, along with the body’s salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
What is internal fever?
An “internal fever” occurs when you feel very hot but the thermometer shows a temperature within a normal range. You may have symptoms very similar to a fever (such as general malaise, chills and cold sweats), however the thermometer remains at 36 to 37°C, which is normal.
