For both adults and kids, time spent outdoors increases all measures of well-being: psychological and physical health, cognitive abilities, and creativity. It is also good for the planet. Here’s a brief review of the research and some suggestions for how to make it happen for your child and yourself. Spending more time outdoors, preferably in natural settings, may be the simplest, healthiest, and most economical remedy for the terrible increase in numbers of children diagnosed with social, emotional, and learning problems over the past two decades. It may also be the answer to many problems suffered by adults in our increasingly rushed, technology-focused lives. And on a global scale, there’s evidence that more people spending more time in natural spaces would contribute to solving the environmental challenges that are increasingly disrupting our lives.
