Helmet correction is actually to achieve head shape correction through physical methods, which will not bring any hidden harm to the body and may cause some skin problems. For example, if the temperature is not well controlled in the process of wearing a helmet, children may get prickly heat if they feel too hot. So let the child be in a comfortable temperature range, and there will be no discomfort. Therefore, parents should pay more attention to their children's wearing process, which can be avoided.
