Fever is the body’s natural defence against infection. Most fevers caused by viral infections resolve on their own with rest and fluids. However, very high fever or fever with certain symptoms needs medical attention.

Common Causes

Viral infections — cold, flu, COVID, dengue, viral fever
Bacterial infections — UTI, throat infection, pneumonia
Vaccinations — mild fever for 24–48 hours is normal
Heat exhaustion
Teething in infants — may cause mild temperature rise
Inflammatory conditions

Home Care and Relief

Paracetamol

Adults: 500–1000mg every 4–6 hours. Children: weight-based dosing per package insert. Do not give aspirin to children under 16. Ibuprofen is an alternative for adults and children over 3 months.

Stay hydrated

Fever causes rapid fluid loss. Drink water, coconut water, ORS, or diluted juice throughout the day. Dehydration makes fever more dangerous.

Rest

The body needs energy to fight infection. Rest reduces metabolic demand and lets the immune system work effectively.

Cool damp cloth

Apply to forehead, armpits, and groin. Change frequently. Draws heat away without causing shivering.

Dress lightly

Wear light, breathable clothing. Avoid heavy blankets. Keep the room ventilated.

Light foods

Offer light, easily digestible food — khichdi, dal, rice water, banana, or toast. Soups maintain hydration and electrolytes.

Tepid sponging for children

Lukewarm sponge bath helps reduce high fever in children. Never use cold water or alcohol rubs.
