Fever FAQs

We have all at one point experienced a rise in our body temperature. Although most people assume fever to be dangerous, it’s not. But, it is the immune system action of fighting an infection. Fever is surrounded by many misconceptions and in this post, we answer some of the questions.

What is Fever?

Fever is a rise in the body’s temperature above the normal range. The average oral temperature is 98.6 degrees Fahrenheit or 37 degrees Celsius. The body temperature varies based on diet, exercise, sleep and the time of day. The body’s temperature is lowest at 3 am and the highest at 6 pm.

Fever is mild if it’s below 100 Fahrenheit. However, when the temperature rises above 100.4 Fahrenheit, it is no longer mild, but a medical emergency.

Fever is not an illness or harmful, but it is the body’s fighting defense against infections. Furthermore, the immune system seems to work efficiently when the temperatures are high. For this reason, most mild fevers can go untreated.

What is the Difference Between Fever and Hyperthermia?

Fever occurs when the body temperature increases and is usually as a response to the body fighting an infection.

Hyperthermia, on the other hand, is when the body can’t respond to heat effectively causing the body temperature to rise. Hyperthermia is a result of heatstroke or side effects of medications.

Because fever is a natural process, the body can regulate the fever and lower the temperature without treatment. However, hyperthermia requires an emergency response because of the body’s inability to regulate heat. Therefore, visit our emergency care when you have hyperthermia symptoms.

What Are the Causes High Body Temperature?

The most common causes of fever are cold and flu. Other causes include gastroenteritis, ear infection, side effects of drugs, conditions that cause body inflammation, vaccines, skin, lung, or throat infections.

When is Medication Given?

Fever can be treated when it is accompanied by discomfort. You can use fever-reducing medication, take enough fluids, or have a lukewarm bath to keep the fever down.

When is Fever an Emergency?

Fever is a medical emergency if it is above 100.4 Fahrenheit or 39 degrees Celsius. Additionally, visit an ER in San Antonio when you have lethargy, vomiting, diarrhea, irritability, trouble breathing, chest pain, or seizures.

Furthermore, seek medical attention if the fever has lasted for more than three days or have an existing medical condition.

What are Febrile Seizures and What Causes It?

Febrile seizures occur in children and are convulsions caused by high body temperature often from an infection. A febrile seizure can be simple or complex. Simple seizures are common and last for a few seconds or minutes.

Complex seizures, on the other hand, last for more than 15 minutes, affects one side of the body, and occurs more than once in 24 hours.

However, visit an emergency room near you regardless of the severity of the seizures whether mild or not.

What to Do When You or Your Loved One Has a Fever?

You can break a fever with these steps:

  • Take the temperature often and assess the symptoms
  • Rest to give your body chance to recuperate
  • Stay hydrated by drinking water and lots of fluid
  • Take medications, but only if the fever is accompanied by discomfort
  • Stay cool and remove the extra clothing
  • Take lukewarm baths. Avoid cold baths, however tempting it might be because they cause shivering and further raises the temperature.
