Fever, hot hands and feet in babies are due to the release of toxins that irritate the body after bacteria or viruses have invaded the body. Fever, hands and feet hot, in fact, is a kind of high fever signal, suggesting that the child needs to take emergency antipyretic drugs. However, the other side also suggests that the child is now in the state of peripheral circulation, this time drinking warm water coupled with oral antipyretic drugs, can make the body temperature drop very quickly. If the child has a fever and cold hands and feet, it suggests that the bacterial toxins are very virulent. In addition, the child’s peripheral circulation is not smooth, blood stagnation, resulting in taking fever-reducing drugs is not easy to fall very quickly, so we need to drink a lot of warm boiled water, to promote blood circulation, toxin excretion.
