Ever wondered why your body temperature matters so much? It&#;s one of the simplest yet most powerful ways your body communicates with you. According to the CDC, fever is one of the top five reasons people seek medical care. Yet, many of us aren&#;t entirely sure what each degree means for our health or what actions to take. With this guide, you’ll decode the Adult&#;s Fever Temperature Chart, learn what each range signifies, and discover the steps you should take to stay healthy.
Why Monitoring Body Temperature is Critical
Body temperature is more than just a number on a thermometer. It&#;s a window into your immune system’s status and your body’s overall health. When it rises or falls outside normal levels, it’s your body signaling that something’s up.
A normal body temperature is typically around °F (37°C), but did you know this “normal” varies slightly for everyone? Some people naturally hover at 97°F (°C), while others might feel their best closer to 99°F (°C). That’s why knowing the ranges and their meanings can help you respond effectively when your temperature starts to climb.
This guide helps adults and caregivers understand the spectrum of body temperatures, from
Fever is one of the body's most effective ways of fighting infection. It is part of your body's defense against infection-causing germs.
You get a fever most often when your body is trying to kill infectious invaders such as viruses or bacteria. A higher body temperature helps the immune system respond more vigorously to the attack, and makes it harder for these microbes to survive.
What is considered a fever in adults?
The average body temperature is ° F (37°C). But "normal" body temperature varies from person to person. It also changes during the day, rising a bit after you eat or exercise. Body temperature is often higher in the afternoon than it is when you wake up in the morning.
Fever means a body temperature of ° F (38°C) or higher.
High fever in adults
While any temperature above your normal temperature range is considered a fever, there are different levels of fever severity:
- Low-grade: to F ( to C)
- Moderate-grade: to F ( to C)
- High-grade: to F ( to 41 C).
When to worry about fever
If you have a fever over °F (40°C), you should call your doctor.
Seek medical help right away if you have a fever along with any of these sympto
What Is a Low-Grade Fever?
Most healthcare providers define a low-grade fever as a temperature between 99 degrees F ( C) and degrees F ( C). A normal body temperature is typically described as F (37 C) but can range from 97 F ( C) to 99 F ( C).
A low-grade fever is often the first sign of an infection. When the body temperature is normal, infectious bacteria and viruses are able to thrive. A fever is the body's way of creating a hostile environment to help neutralize them.
Low-grade fevers also have non-infectious causes, including diseases, vaccines, and medications that affect the body's "thermostat," known as the hypothalamus.
This article explains the symptoms and causes of low-grade fevers. It also offers tips on how to manage a fever and when it is time to see a healthcare provider.
Low-Grade Fever Symptoms
Although fever is the body's defense against infection—increasing the internal temperature to where most bacteria and viruses are unable to survive—it can cause a cascade of symptoms the higher the temperature gets.
With a low-grade fever, the condition is often asymptomatic (without symptoms) or subclinical (not severe enough to cause definite or
