When a baby has a fever, a cold compress on the forehead can play a role in aiding physical cooling. When a baby is under a low fever, a cold compress on the forehead can be used, along with drinking more water, feeding water regularly, or wiping the body with warm water, which can play a role in aiding physical cooling. If the child’s temperature has a tendency to drop after an hour or so of physical cooling, you can stop applying cold compresses to the forehead and continue to give more water. If a long time cold compress, the child will also have chills, discomfort, so the time should not be too long. If the child is in a high fever state, after oral antipyretic drugs with cold compresses and other means of physical cooling, the time is also in an hour or so, the temperature dropped that can stop cold compresses, long-term cold compresses children will also feel uncomfortable. Parents must pay attention to the changes in the baby’s temperature when the fever is high, and if the temperature does not drop significantly by physical cooling, they need to actively take the baby to the hospital for further consultation and treatment.
