What Is Fever?

Fever is not a disease. It is the body's natural defense mechanism against infections and inflammation.

A normal body temperature ranges between 36.5°C and 37.5°C.

Generally,

• 37.6–37.9°C: Mild elevation
• 38°C or above: Fever
• 39°C or above: High fever
• 40°C or above: Very high fever requiring prompt medical evaluation

The number itself is only part of the picture. Your overall condition is often more important than the temperature reading.

Common Causes of Fever in Pakistan

Pakistan has seasonal illnesses that make fever one of the most common reasons for clinic visits.

The most frequent causes include:

Viral infections

Examples include:

• Common cold
• Influenza
• COVID-19
• Viral gastroenteritis

Usually improve within a few days.

Dengue Fever

More common during the monsoon season.

Typical symptoms include:

• High fever
• Severe body pain
• Pain behind the eyes
• Headache
• Rash
• Low platelet count

Typhoid Fever

Usually caused by contaminated food or water.

Symptoms include:

• Persistent fever
• Abdominal pain
• Weakness
• Poor appetite
• Constipation or diarrhea

Malaria

Occurs in certain regions of Pakistan.

Symptoms:

• Fever with chills
• Sweating
• Body aches
• Headache

Urinary Tract Infection (UTI)

Especially common in:

• Women
• Elderly
• Children

Symptoms:

• Burning during urination
• Frequent urination
• Fever

Chest Infection or Pneumonia

Symptoms include:

• Fever
• Cough
• Chest pain
• Difficulty breathing

Symptoms That Often Accompany Fever

People may experience:

• Chills
• Sweating
• Headache
• Muscle aches
• Fatigue
• Loss of appetite
• Weakness
• Sore throat
• Runny nose
• Nausea

How to Measure Temperature Correctly

Digital thermometers provide the most accurate readings.

Recommended sites include:

• Mouth (oral)
• Armpit (axillary)
• Ear (tympanic)
• Forehead (infrared, if used correctly)

Avoid relying on touch alone.

Home Treatment for Fever

Most uncomplicated viral fevers can be managed safely at home.

1. Drink Plenty of Fluids

Good options include:

• Water
• ORS
• Soup
• Fresh lemonade
• Coconut water
• Clear broths

Hydration helps prevent complications.

2. Get Adequate Rest

The body heals faster during sleep.

Avoid strenuous exercise while febrile.

3. Wear Light Clothing

Avoid wrapping yourself in multiple blankets unless you are actively shivering.

Heavy clothing can trap heat.

4. Use Lukewarm Sponging If Necessary

Use lukewarm water.

Do not use:

• Ice water
• Alcohol rubs
• Very cold baths

These methods can worsen shivering and discomfort.

5. Medicines

Paracetamol

Usually the safest first choice for reducing fever when taken at the recommended dose.

Avoid exceeding the maximum daily dose and check whether combination cold medicines already contain paracetamol.

Ibuprofen

May be appropriate for some adults and children over 6 months, but it should be avoided in certain situations such as dehydration, some kidney problems, stomach ulcers, or specific medical conditions. Ask your healthcare provider if you're unsure.

Avoid taking antibiotics without a doctor's prescription.

Antibiotics do not treat viral infections.

Foods to Eat During Fever

Choose light, easily digestible foods such as:

• Rice
• Yogurt
• Bananas
• Apples
• Khichdi
• Chicken soup
• Oatmeal
• Toast

Eat small meals if your appetite is reduced.

Foods to Avoid

Avoid:

• Fried foods
• Very spicy meals
• Excess sugary drinks
• Alcohol
• Excess caffeine

Fever in Children

Children frequently develop fever due to viral infections.

Parents should remain calm while monitoring:

• Activity level
• Drinking fluids
• Urination
• Breathing
• Rash
• Sleepiness

A playful child with fever is generally less concerning than a child who is difficult to wake, unusually lethargic, or not drinking fluids.

Never give aspirin to children because of the risk of serious complications.

When Should You Visit a Doctor?

Arrange a medical review if:

• Fever lasts longer than three days.
• Temperature repeatedly exceeds 39°C.
• Severe sore throat develops.
• Persistent cough occurs.
• Burning urination is present.
• Severe abdominal pain develops.
• Fever keeps returning.
• You have diabetes, cancer, are pregnant, or have a weakened immune system.

When Should You Go to the Emergency Department?

Seek urgent medical care immediately if fever is accompanied by:

• Difficulty breathing
• Chest pain
• Confusion
• Loss of consciousness
• Seizures
• Severe dehydration
• Neck stiffness
• Purple or widespread rash
• Persistent vomiting
• Inability to drink fluids

Common Myths About Fever

Myth: Every fever needs antibiotics.

Fact: Most fevers are caused by viral infections and do not improve with antibiotics.

Myth: Ice baths reduce fever faster.

Fact: Ice baths may increase shivering and discomfort. Lukewarm sponging is generally preferred if cooling measures are needed.

Myth: Fever itself causes brain damage.

Fact: Most fevers do not cause brain damage. Extremely high body temperatures from conditions such as heat stroke are different from typical infectious fevers and require emergency treatment.

Myth: You should stop eating completely.

Fact: Light meals and adequate hydration support recovery.

Frequently Asked Questions

Is 102°F dangerous?

Not necessarily. The cause of the fever and the person's overall condition are more important than the number alone.

Can I shower during fever?

Yes. A lukewarm shower is generally safe if you feel well enough. Avoid very cold water.

Can dengue start with fever only?

Yes. Early dengue may initially present with fever before other symptoms develop.

Should I exercise during fever?

No. Rest is recommended until you have recovered.

Why does fever get worse at night?

Body temperature naturally varies during the day and often rises slightly in the evening, making fever feel more noticeable.

Preventing Fever

Reduce your risk by:

• Washing hands regularly.
• Drinking safe, clean water.
• Eating properly cooked food.
• Staying up to date with recommended vaccinations.
• Avoiding close contact with people who are ill when possible.
• Using mosquito protection during dengue and malaria seasons.

Final Thoughts

Fever is one of the most common reasons people seek medical care. In many cases it is a temporary response to a viral infection, but persistent fever or fever accompanied by warning signs can indicate a more serious condition.

Pay attention to the whole clinical picture, not just the thermometer reading. Appropriate hydration, rest, and timely medical assessment when needed are key to a safe recovery.
