The danger of applying hot compresses to the fontanel of a baby’s cold includes the high temperature of the hot compresses, which burns the baby’s skin; the excessive strength of the hot compresses can cause damage to the brain blood vessels or bone marrow, or even lead to the consequences of intracranial hemorrhage, and so on. There is no scientific basis for applying hot compresses to the fontanel for the treatment of a baby’s cold, and blindly applying hot compresses may, on the contrary, result in scalding the baby’s skin because of the high temperature of the hot compresses. Because the fontanel is located at the junction of the baby’s three skulls, not yet fully grown, if the parents a little force or accidentally touch this position, may lead to the baby’s bone marrow, cerebral blood vessels to varying degrees of damage, and even lead to intracranial hemorrhage phenomenon. When a baby has a cold, it is recommended to go to the hospital in time for relevant examinations, such as blood routine, etc., to clarify the cause of the cold and then actively treat the symptoms, and at the same time pay attention to drink more water.
