It starts in the brain
To really understand what is fever, you need to know the hypothalamus. The hypothalamus is the brain center. Think of it as the body’s thermostat, the device is in the walls of many houses and used for adjusting the temperature of the heating and / or air conditioning. The hypothalamus knows what temperature should be the body of a person and sends messages to the body to be set and maintained at that temperature.
The body temperature of most humans is around 37 ° C (98.6 ° Fahrenheit). Some people will have a normal temperature a little higher, others will have it a little lower.
The body temperature of most people also varies slightly during the day: it will be a little lower in the morning and a little higher in the evening.
