Pediatric fever with cold hands and feet is a common phenomenon that can easily occur when the baby’s goal of body temperature is set at a relatively high level for some reason and the whole body is mobilized to reach the target temperature. In order to obey the body’s highest instructions to raise the body temperature, the peripheral blood vessels will be contracted, reducing the skin heat dissipation, so it appears that the hands and feet are very cold. Therefore, in fact, the appearance of cold hands and feet in pediatric fever is a signal telling us that the child is going to have a high fever and is in a period of rapidly rising body temperature. This is a good time to keep your child warm, because if he or she is underdressed or covered and too cold, he or she may be very uncomfortable and unable to get a good night’s rest. However, over-warming is likely to cause the body temperature to rise too high, which is like aiding and abetting the fever. This is also a time to monitor the child’s temperature closely, especially for children with a history of febrile convulsions, which can easily occur during a period of rapidly rising body temperature. Symptomatically, you can wash your child’s hands and feet with warm water to make them comfortable. Monitoring body temperature reaches 38.5 ℃ or more when you can take a little antipyretic drugs, timely control of body temperature. In short, the child’s fever with cold hands and feet is the child’s helplessness, but also to tell us that his body temperature is rapidly going up, and needs more attention from us.
