Fever, hot hands and feet in babies are usually seen in the case of low fever at the beginning of a cold. In low fever, the blood circulation in the extremities is smooth and the blood vessels are dilated, so it is easy to show that the forehead is hot and the palms and feet are warm. You can use physical cooling methods by wiping your palms, feet, armpits, forehead and back with warm water to help dissipate heat. You can also take a hot bath and soak for a longer period of time, which will increase sweating and promote heat dissipation. If your child has a high fever of 39°C or higher, you need to take fever-reducing medication such as ibuprofen suspension in time for treatment. During the fever period, pay attention to ensure sufficient water intake, drink more warm water or juice, you can also use cold water to ice the forehead to assist in cooling. In addition, if your child has repeated fevers, you need to go to the pediatrician for routine blood tests to see if there is a bacterial or viral infection, and give timely symptomatic anti-inflammatory and antibacterial treatment, so that the fever can be treated more thoroughly.
