When managing a fever, the instinct to use cold water can be counterproductive, according to Dr. Meenal Thakral, a Consultant in Geriatric Medicine at Artemis Hospitals. She advises that lukewarm water is more effective as it cools the body gradually, preventing stress and discomfort. Cold water can cause blood vessels to constrict and trigger shivering, which generates more heat. This is particularly concerning for children and older adults, who have less stable temperature control. Dr. Thakral recommends using a soft cloth with lukewarm tap water to sponge areas like the forehead and neck, ensuring the room is warm and stopping if shivering occurs. The focus should be on comfort and gradual cooling, alongside proper hydration and adherence to medication like paracetamol as prescribed. Always consult a healthcare provider before starting any routine.
