Traditional methods such as applying cloths soaked in cold, vinegared water or containing crushed aspirin to a child's body (e.g., armpits) to reduce fever are completely incorrect. Such methods do not help lower fever and can negatively affect the child's natural thermoregulation. Instead, for sudden or persistent fever spikes, a lukewarm shower, ensuring the child's head remains out of the water, can be a more appropriate measure. If the fever does not subside or if symptoms worsen, it is essential to seek professional medical advice.
