Fever is not an illness; rather, it is a physical manifestation of some underlying disease or infection. It occurs when your body’s temperature rises above the normal range of 36.5-37.5°C (97.7-99.5°F). Fever is an indicator that your body is trying to fight off an illness, and it is a natural response to infections or disease. In this article, we will discuss the signs of a fever and what you should look for in your body.
What is a fever?
A fever is a temporary increase in your body’s temperature that is often a symptom of an underlying infection or illness. It occurs when your body’s immune system releases chemicals that raise your body’s temperature in an attempt to fight off an infection. Fevers are often accompanied by other symptoms, such as chills, sweating, headaches, and muscle aches.
What causes a fever?
Fevers can be caused by a variety of factors, including:
- Viral infections, such as the flu or colds
- Bacterial infections, such as strep throat or pneumonia
- Parasitic infections, such as malaria
- Autoimmune diseases, such as lupus or rheumatoid arthritis
- Medications, such as antibiotics or blood pressure medications
- Heat exhaustion or heat stroke
What are the signs of a fever?
The signs of a fever include:
Raised body temperature
The most obvious sign of a fever is an elevated body temperature. You can check your body temperature using a thermometer. Normally, a body temperature of greater than 37.5 °C (99.5°F) is considered a fever.
Chills and sweating
Chills and sweating are common signs of fever. When your body temperature rises, you may feel cold and shiver as your body attempts to raise its temperature. Once your body temperature has stabilized, you may feel warm and sweat as your body tries to cool down.
Headaches are a common symptom of fever. They can be caused by the increase in body temperature or the underlying illness that is causing the fever.
Muscle aches or joint pain are a common symptom of fever. They can be caused by the underlying illness that is causing the fever or by the body’s attempt to fight off the infection.
Fatigue and weakness
Fatigue and weakness are common symptoms of fever. They can be caused by the underlying illness that is causing the fever or by the body’s attempt to fight off the infection.
Loss of appetite
Loss of appetite is a common symptom of fever. It can be caused by the underlying illness that is causing the fever or by the body’s attempt to conserve energy while fighting off the infection.
When should I see a doctor for a fever?
Most fevers are not serious and will go away on their own within a few days. However, you should see a doctor if:
- Your fever lasts for more than three days
- You have a fever of 40°C (104°F) or higher
- You have difficulty breathing or chest pain
- You have a severe headache
- You have a rash
- You are vomiting or have diarrhea
- You have a weakened immune system
How can I treat a fever?
Most fevers don’t require specific treatment as they are a natural response of the body to fight off an infection. You can take steps to reduce your fever and make yourself more comfortable by:
- Drinking plenty of fluids to prevent dehydration
- Resting to conserve energy and allow your immune system to fight off the infection
- Taking over-the-counter medications such as acetaminophen or ibuprofen to reduce fever and relieve any accompanying pain or discomfort.
Preventing a fever
The best way to prevent a fever is to practice good hygiene. This includes:
- Washing your hands regularly with soap and water
- Covering your mouth and nose when coughing or sneezing
- Avoiding close contact with people who are sick
- Staying home from work or school if you are sick
- Getting vaccinated against infectious diseases when available
