1. Behavior needs to be based on cognition, but cognition alone is not enough to directly translate into behavior. Preschool children's cognitive level is still in the development stage, and they only know what a healthy lifestyle is, but how to really practice and implement these concepts needs further study and practice.
2. Children's behavior is influenced by many factors, including environment, social culture and family education. For example, family environment may affect children's eating habits and sports, and social culture may also affect children's behavior. For example, cultural differences may lead to different dietary preferences.
3. Preschool children's self-control ability and self-management ability have not been fully developed, so it is difficult to adhere to healthy behavior. For example, they will try some unhealthy foods or behaviors out of curiosity or other reasons.
