What should I do if a child has a fever at night?

When a child has a fever at night, first measure their body temperature. If the temperature does not exceed 38.5°C, physical cooling methods can be used, such as applying cold compresses with a damp towel to areas with major blood vessels like the forehead, neck, and armpits, or using fever-reducing patches. At the same time, ensure the child is dressed in breathable, lightweight clothing and avoid using overly thick blankets. Additionally, provide adequate fluids to promote sweating and help lower body temperature. If the temperature exceeds 38.5°C, it is recommended to seek medical attention promptly and use fever-reducing medications under a doctor's guidance.
