Most of us are familiar with a fever. Many of us have experienced a fever as a result of stomach flu, but there are a lot of other reasons why we can experience a fever. A fever—medically known as pyrexia—is a condition that occurs when the temperature of the body becomes higher than average. In most cases, this suggests that the person is experiencing some sort of infection, although this isn’t always the case.
The body usually rests at a temperature of about 98.6 degrees Fahrenheit and fluctuates a bit during the day. If you’re experiencing a body temperature of greater than 100.4 degrees Fahrenheit, then you’re experiencing a fever. There are a number of symptoms that often occur alongside a fever, such as shaking and chills. These can be indicative of the condition that might be causing your fever in the first place.
In the case of most infections, a fever is a sign that your body is fighting an infection. Many bacteria aren’t able to thrive as well in higher temperatures, so when your immune system raises your body’s temperature, it becomes easier for it to ward off any bacteria that might be present. As mentioned above, though, there are quite a few things that can contribute to the development of a fever. In this article, we’re going to discuss some of the most common issues that can contribute to the development of a fever.
Cause #1: Flu
Flu—the common term used to describe an infection caused by the influenza virus—is one of the most common causes of a fever. In this case, the body is attempting to make the body a less safe environment for the virus to thrive in.
Flu often comes with a host of other symptoms such as nausea, vomiting, chills, and general malaise. These symptoms are generally easy to identify.
