4．Children who spend more time playing adventurously have lower symptoms of anxiety and depression，and were happier，according to a new research.
A study led by the University of Exeter asked parents how often their children engaged in play that was "thrilling and exciting"，where they might experience some fear and uncertainty.
The study comes at a time when today's children have fewer opportunities for adventurous play out of sight of adults，such as climbing trees，riding bikes or jumping from high surfaces.The study sought to test theories that adventurous play offers learning opportunities that help build resilience in children，thereby helping to prevent mental health problems.
The research team surveyed nearly 2，500 parents of children aged 5-11 years.Parents completed questions about their child's play，their general mental health and their mood.The research was carried out with two groups of parents：a group of 427 parents living in Northern Ireland and a nationally representative group of 1，919 parents living in Great Britain.
Researchers found that children who spend more time playing outside had fewer "internalizing problems"—characterized as anxiety and depression.The study in the Great Britain group also found that the effect was more pronounced in children from lower-income families than those growing up in higher-income households.
Helen Dodd，a professor of Child Psychology at the University of Exeter，who led the study，said， "We now urgently need to invest in and protect natural spaces，well-designed parks and adventure playgrounds，to support the mental health of our children."
Welcoming the findings，Jacqueline O'Loughlin，Chief Executive of PlayBoard NI，said， "It is clear from the research findings that playing，taking risks and experiencing excitement outdoors make positive contributions to children's mental health and emotional well-being.The rewards of allowing children to self-regulate and manage challenge in their play are widespread and far-reaching.Adventurous play helps children to build the resilience needed to cope with and manage stress in challenging circumstances."
