Fever Unmasked: How to Recognize If You’re Sick

Have you ever felt hot and cold at the same time? Have you ever wondered if you have a fever or not? Getting sick is inevitable in life, but knowing when you have a fever can be helpful in taking care of yourself. Here are some things you should know about fevers:

What is a Fever?

A fever is when your body temperature is higher than the normal range. The normal range for body temperature is between 97°F (36.1°C) to 99°F (37.2°C). When your body temperature rises above this range, it indicates that your body is trying to fight off an infection or illness.

What Causes a Fever?

Fevers are caused by various infections or illnesses that affect your body’s immune system. Some common causes of fevers are flu, common cold, pneumonia, strep throat, and urinary tract infections. In rare cases, fevers can also be caused by more severe infections like HIV, tuberculosis, and malaria.

How Do You Know If You Have a Fever?

The most common way to check for a fever is by using a thermometer. There are different types of thermometers available in the market, but the most reliable one is the digital thermometer. You can use it to take your temperature orally, rectally, or under the armpit. The normal body temperature varies depending on the age and gender of the person. If your temperature measures more than 100.4°F (38°C) orally, or 100°F (37.8°C) under the armpit, then you have a fever.

What Are the Symptoms of a Fever?

The symptoms of a fever can vary from person to person, but some common symptoms include:

  • Headaches
  • Muscle aches
  • Sweating and shivering
  • Fatigue and weakness
  • Loss of appetite
  • A dry cough

When Should You See a Doctor?

Most fevers go away on their own within a few days, but you should see a doctor if:

  • Your fever lasts more than three days
  • Your fever rises above 103°F (39.4°C)
  • You have other symptoms like a severe headache, difficulty breathing, chest pain, rash, throat swelling, or abdominal pain.

How Can You Treat a Fever?

If you have a mild fever, you can treat it by:

  • Drinking plenty of fluids
  • Resting and relaxing
  • Wearing lightweight and comfortable clothing
  • Taking over-the-counter medications like acetaminophen, ibuprofen, or aspirin

It’s important to note that if you have a fever, you should avoid going to work or school to prevent the spread of infection to others.

What Should You Do If You Have a High Temperature?

Can stress cause a fever?

Stress can cause an increase in body temperature, but it usually doesn’t lead to a fever. However, chronic stress can weaken your immune system and make you more susceptible to infections and illnesses.

Can I exercise with a fever?

A fever itself is not contagious, but the infections or illnesses that cause fever can be contagious.

Should I go to work if I have a fever?

You should not go to work if you have a fever since it can spread the infection to others. It’s important to rest and isolate yourself until your fever subsides.

Can a fever cause seizures?

Febrile seizures can occur in some children who have a high fever. It’s important to monitor your child’s temperature and seek medical attention if they have a seizure.

Can I get a fever from a vaccine?

Some vaccines can cause a low-grade fever as a side effect, but it usually goes away within a few days. It’s important to talk to your doctor if you have any concerns about vaccine side effects.

Can a fever cause hallucinations?

A high fever can cause delirium or altered mental status, which can lead to hallucinations in some people. It’s important to seek medical attention if you experience any confusion or abnormal behavior during a fever.


Fevers are a common symptom of infections and illnesses, but they can be easily managed with proper care and rest. It’s important to monitor your temperature and seek medical attention if your fever lasts longer than three days or is higher than 103°F (39.4°C). Taking preventive measures like washing your hands and staying away from sick people can help reduce your risk of getting a fever.
