/kloc-Tissot, a famous French physician in the 0 th and 8 th centuries, said: "Exercise can replace almost any medicine in terms of its function, but no medicine in the world can replace the function of exercise." Exercise is especially important for children. Outdoor activities are not only a very important part of children's daily life, but also the basic form of children's exercise.

First, outdoor activities are an important measure to keep fit and reduce and prevent diseases.

Outdoor activities can strengthen children's physique and promote their healthy development. Children are in the period of growth and development, the development of various organs and systems of the body is not yet mature and perfect, and their adaptability to the external environment is weak, so they are easily influenced by various natural factors. Taking outdoor sports activities suitable for children's physiological characteristics can improve their adaptability and disease resistance.

Some games with less exercise, such as role games and intelligence games. Scientific sports activities can improve children's basic activity ability and sports skills, so as to achieve the purpose of exercising and strengthening physical fitness.

Second, outdoor activities are an effective way to promote children's psychological development.

Outdoor activities are children's favorite activities, and almost all children like to go out for a walk. Taking part in outdoor sports activities can not only make children refreshed and happy, but also enhance their self-confidence and cultivate their brave, strong and quick-witted will.

Outdoor activities are a process of enjoying happiness for children. In outdoor activities, children catch insects in the grass in twos and threes and observe the shapes and habits of these small creatures, so that children will be more natural and relaxed in the game.

In the whole outdoor activities, teachers no longer play the role of managers, educators and guides, but become children's innocent playmates, and tutors become beneficial friends, so that children can experience a brand-new and harmonious change in interpersonal relationships.

Third, outdoor activities are the best way to strengthen safety education and enhance children's awareness of self-protection

Outdoor venues have a wide range of activities and children are scattered around, so it is impossible for teachers to take care of every child. Therefore, before the activity, teachers should always explain the rules of the activity and related safety matters to children, enhance their awareness of self-protection and foresee possible unsafe factors.
