The difference between preschool children's health education and preschool hygiene is that preschool hygiene is a discipline to study, protect and improve preschool children's health, and preschool children's health education is an educational activity to enrich preschool children's health knowledge, establish healthy attitudes and cultivate healthy behaviors. Although preschool children's health education and preschool hygiene both serve preschool children's health, there are obvious differences between them.
