6 reasons children need to play outside
- By Claire McCarthy, MD, Senior Faculty Editor, Harvard Health Publishing
Here’s something really simple you can do to improve your child’s chance of future health and success: make sure he spends plenty of time playing outside.
There are many ways in which this generation’s childhood is different from that of the last generation, but one of the most abrupt contrasts is the degree to which it is being spent indoors. There are lots of reasons, including the marked increase in time spent interacting with electronic devices, the emphasis on scheduled activities and achievements, concerns about sun exposure — and, for many families, the lack of safe outdoor places to play. It’s not just children; adults are spending less time outdoors as well.
Here are six crucial ways playing outside helps children:
1. Sunshine. Yes, sun exposure — especially sunburns — can increase the risk of skin cancer. But it turns out that our bodies need sun. We need sun exposure to make vitamin D, a vitamin that plays a crucial role in many body processes, from bone development to our immune system. Sun exposure also plays a role our immune system in other ways, as well as in healthy sleep — and in our mood. Our bodies work best when they get some sunshine every day.
2. Exercise. Children should be active for an hour every day, and getting outside to play is one way to be sure that happens. They can certainly exercise indoors, but sending them outdoors — especially with something like a ball or a bike — encourages active play, which is really the best exercise for children.
3. Executive function. These are the skills that help us plan, prioritize, troubleshoot, negotiate, and multitask; they are crucial for our success. Creativity falls in here, too, and using our imagination to problem-solve and entertain ourselves. These are skills that must be learned and practiced — and to do this, children need unstructured time. They need time alone and with other children, and to be allowed (perhaps forced) to make up their own games, figure things out, and amuse themselves. Being outside gives them opportunities to practice these important life skills.
4. Taking risks. Children need to take some risks. As parents, this makes us anxious; we want our children to be safe. But if we keep them in bubbles and never let them take any risks, they won’t know what they can do — and they may not have the confidence and bravery to face life’s inevitable risks. Yes, you can break an arm from climbing a tree — and yes, you can be humiliated when you try to make a friend and get rejected. But that doesn’t mean you shouldn’t try; the lessons we learn from failure are just as important as those we learn from success.
5. Socialization. Children need to learn how to work together. They need to learn to make friends, how to share and cooperate, how to treat other people. If they only interact in very structured settings, such as school or sports teams, they won’t — they can’t — learn everything they need to know.
6. Appreciation of nature. So much of our world is changing, and not for the better. If a child grows up never walking in the woods, digging in soil, seeing animals in their habitat, climbing a mountain, playing in a stream, or staring at the endless horizon of an ocean, they may never really understand what there is to be lost. The future of our planet depends on our children; they need to learn to appreciate it.
So try it. Do what our parents did: send your children outside. Even better, go with them. And do everything you can to be sure that every child can do the same.
