How to Reduce Fever Safely

Fever is a natural immune response — a rise in body temperature above 38°C (100.4°F) that signals the body is fighting an infection. In most cases, fever is beneficial and does not need to be suppressed unless it causes significant discomfort or rises dangerously high.

Safe, evidence-based approaches to reducing fever include: taking paracetamol (acetaminophen) or ibuprofen at appropriate doses, staying well hydrated with water or electrolyte drinks, resting in a cool but not cold environment, applying a cool (not ice-cold) damp cloth to the forehead, and wearing light clothing.

Do NOT use aspirin in children under 16 due to risk of Reye's syndrome. Cold baths and alcohol rubs are not recommended as they can cause shivering, which raises core temperature. Bundling up in heavy blankets is counterproductive.

Seek emergency care if fever exceeds 39.5°C in adults or 38°C in infants under 3 months, if fever is accompanied by severe headache and stiff neck (possible meningitis), difficulty breathing, confusion, a non-blanching rash, or if fever persists beyond 3 days without improvement.
