Fever: 7 Most Common Myths and the Truth from Medical Experts

Fever is one of the most common symptoms of viral and bacterial infections. It’s a natural immune response — yet many myths about fever lead to improper treatment. Let’s break down the most widespread misconceptions from the perspective of evidence-based medicine.

Myth #1: You should lower a fever immediately

In reality, a temperature of 37.5–38°C (99.5–100.4°F) is a normal immune reaction. The body uses fever to slow down virus replication and activate protective cells.

You should lower the temperature if:

it rises above 38–38.5°C (100.4–101.3°F)
there is severe weakness, vomiting, or muscle cramps
the person has chronic illnesses or is pregnant
it’s a young child who poorly tolerates fever

👉 In most cases, doctors do not recommend reducing a fever below 38°C (100.4°F) if the patient feels generally well.

Myth #2: A high fever always means a dangerous illness

The number on the thermometer does not always reflect the severity of an infection.

A child may have 39°C (102.2°F) with a typical cold.
An adult may have only 37.2°C (99°F) while having a serious bacterial condition.

Doctors evaluate not only the temperature but also:

accompanying symptoms (rash, vomiting, shortness of breath, etc.)

overall condition

duration of fever

Myth #3: You can lower fever with alcohol or vinegar rubs

This method is dangerous and ineffective.

Alcohol or vinegar rubs may cause:

❌ poisoning from fumes
❌ chemical skin irritation
❌ blood vessel spasm
❌ uncontrolled heat loss

Evidence-based medicine recommends only safe cooling methods:

cool fluids
a well-ventilated room
light clothing
fever-reducing medications when indicated

Myth #4: If you have a fever, you need antibiotics

Antibiotics do not lower temperature and do not work against viruses.

They are prescribed only when:

there are clear signs of a bacterial infection
a doctor confirms the need
tests support antibiotic therapy

Self-medicating with antibiotics → risk of resistance, allergies, and complications.

Myth #5: Fever is harmful and must be reduced at all costs

Mild fever plays a protective role:

activates white blood cells
slows virus replication
helps the body recover faster

The goal is to monitor the condition — not to bring the temperature down to normal at any cost.

Myth #6: If a child feels hot, you should bundle them up

Over-covering can raise the temperature even higher.

Proper approach:

ensure fresh air and plenty of fluids

dress the child lightly

keep the room at 18–21°C (64–70°F)

Myth #7: You can guess the temperature without a thermometer

Even a doctor can only estimate temperature approximately. A difference of 0.5–1°C can change treatment decisions.

A reliable electronic thermometer is essential in every household.
