I never really thought of the reason for all the different playground equipments until now, when I have been spending a lot of time hanging in playgrounds (that is BTW in Finnish leikkialue).

Most of the equipments are still same as in my childhood: swings, carousels, springs, slides, and climbing frames. According to the manufacturers, they are made to develop children’s balance, muscles, spatial awareness and sense of rhythm.

According to the studies it is indeed so. Physical playing develops skills needed for surviving in modern world. These exercises develop the ability to reach and grasp, estimate measures and the power needed to crawl, run or climb. These skills even help them to develop the ability to write.

In his book "The importance of play: Moving and Learning for the Young Child" (1990) C. S. Rogers says that play supports the entire development of a child in all levels: physically, cognitively, socially and emotionally. So not only the physical part is present on play, but also other qualities what are needed for growing up.

As the saying goes, play is a child’s work. Through play, children learn how society works, about their environment and of their own skills. Along with physical exercise, playing gives children the lessons of teamwork skills and other social interaction - like co-operation, taking turns, play by the rules and lead the team - and provides sources for intellectual development. Play develops the creativity and language skills when interacting with others.

And to go even further: positive experiences while play creates positive emotions. That is good for child’s well-being. Play, which is closely connected with imagination, can help child to master their feeling and experiences, even the negative ones. I read somewhere that when children feel secure and safe while play, they acquire important components of positive emotional health.

Playing is not just for the human child while growing up. Other animals play too. So it is not something we, or our age, invented. Play is something built inside us, and it truly has an important meaning for our development.
