Why Do We Get Fevers?

why do we get fevers

A fever is the body’s defensive response to infection. When we are infected with a virus, bacteria, or other organism, our White blood cells release a substance known as pyrogen, which is carried to the hypothalamus. The fever results in a generalized body heating. This is called pyrexia. It is an important reaction to any infection, especially since our bodies are constantly being bombarded by pathogens.

A fever is a significant increase in an animal’s body temperature. It is caused by inflammation, illness, and medication. However, fevers can also occur for no apparent reason. In this article, we’ll learn how fevers are triggered, and how they’re treated. The temperature-raising process is mediated by inflammatory cells, chemicals, hormones, and brain activity. Fortunately, fevers can be treated in many ways.

The pyrogen-inducing chemical, interleukin-1, triggers a protective response by the body. This chemical, also known as pyrogen, binds to receptors on the hypothalamus. It then signals the body to generate more heat. Usually, a fever occurs in children, as their immune systems are less developed and are more susceptible to infection. But a fever can occur in adults, too.

A fever can be dangerous, especially in children, because they may experience seizures. A temperature that reaches 40 degrees Celsius is potentially life-threatening and should be treated by a medical professional. In addition, fevers of a higher temperature indicate an infection. Even if it is not life-threatening, it is always advisable to seek medical attention as soon as possible. If you suspect that your child may be suffering from an infection, talk to a medical professional.
