Whether you’re feeling under the weather or just curious about your current state of health, it’s important to know if you have a fever. A fever is a bodily response to infection or illness, and it can be an indicator of a variety of conditions. In this article, we’ll explore how to detect a fever and what you should do if you have one.
What is a Fever?
A fever is a temporary increase in body temperature, usually caused by an infection. The average body temperature for adults is 98.6 degrees Fahrenheit (37 degrees Celsius), but this can vary by a degree or more depending on the individual. When your body temperature rises above this normal range, you have a fever.
What are the Symptoms of a Fever?
Common symptoms of a fever include:
- Warm forehead or body
- Chills or shivering
- Sweating
- Feeling tired or weak
- Headache
- Muscle aches
- Loss of appetite
How to Check for a Fever
There are several ways to check for a fever:
Use a Thermometer
The most accurate way to check for a fever is to use a thermometer. There are several types of thermometers available:
- Oral thermometers are placed under the tongue to measure body temperature.
- Ear thermometers use infrared technology to measure temperature from the ear canal.
- Rectal thermometers are inserted into the rectum to measure temperature.
- Forehead thermometers use infrared technology to measure temperature from the forehead.
Each type of thermometer has its pros and cons, but generally, oral and ear thermometers are the most convenient for home use.
Check for Physical Signs
You can also check for physical signs of a fever, such as a warm forehead or body. However, this method is not as accurate as using a thermometer, and it can be difficult to detect a low-grade fever using this method.
What to Do If You Have a Fever
If you have a fever, there are several things you can do to help your body fight off the infection:
- Stay hydrated by drinking plenty of fluids.
- Get plenty of rest.
- Take over-the-counter medications like acetaminophen or ibuprofen to reduce fever and relieve symptoms.
- If your fever is very high or if you are experiencing other symptoms like severe headaches, shortness of breath, or chest pain, seek medical attention immediately.
