In the past, a standard of 37 degrees Celsius This has been challenged in recent years, with anywhere from around 36 to just over 37 degrees Celsius 97 to 99 Fahrenheit expected in a typical adult, and children running a touch warmer with common temperatures of up to 38 degrees Celsius about Fahrenheit.
Scientifically speaking, there is no specific degree of change in temperature universally considered as a fever. Limits vary between different medical systems around the globe and are often based on age and history.

The body's preferred temperature range is managed by a part of the nervous system called the hypothalamus. This small nub of brain tissue generates various biological responses that increase or decrease temperatures, such as by burning glucose through increased muscle movements shivering or increasing skin evaporation sweating.
As the body's thermostat, the hypothalamus can also have its preferred temperature changed by materials known as pyrogens. These are molecules typically produced by bacteria, viruses or even white blood cells , which cause the hypothalamus to reset the body's ideal temperature at a higher limit.
Why do we get fevers? For hundreds of millions of years , animals have managed infections by behaviourally or metabolically raising their body temperature. Exactly how this increased warmth fights off invaders isn't clear. There is little evidence to suggest that a such a moderate jump in temperature is of direct threat to disease-causing viruses and bacteria. In other words, some parts of our immune system have simply evolved to work best when the heat is on.
