Spending time in and around coastal and inland water areas – known as blue spaces – in childhood can lead to better mental health later in life, new research has found.
The BlueHealth International Survey (BIS) used data from over 15,000 people across 14 European countries and four other non-European countries/regions (Hong Kong, Canada, Australia and California), and the positive impact of blue spaces was replicated in all 18 territories.
Respondents were asked to recall their blue space experiences between the ages of 0-16 years including how local they were, how often they visited them, and how comfortable their parents/guardians were with them playing in these settings, as well as more recent contact with green and blue spaces over the last four weeks, and mental health over the last two weeks.
The survey, led by the University of Exeter, found that individuals who recalled more childhood blue space experiences tended to place greater intrinsic value on natural settings in general, and to visit them more often as adults – each of which, in turn, were associated with better mental wellbeing in adulthood.
While mounting evidence shows that spending time in and around green spaces such as parks and woodlands in adulthood is associated with stress reduction and better mental health, this is some of the first investigation into the benefits of blue spaces, or the role childhood contact has in these relationships in later life.
Valeria Vitale, lead author and PhD candidate at Sapienza University of Rome, said: “In the context of an increasingly technological and industrialised world, it’s important to understand how childhood nature experiences relate to wellbeing in later life.
“Our findings suggest that building familiarity and confidence in and around blue spaces during childhood may stimulate an inherent joy of nature and encourage people to seek out recreational nature experiences, with beneficial consequences for adult mental health.”
Dr Mathew White, co-author and senior scientist at the University of Vienna, said: “The current study is adding to our growing awareness of the need for urban planners and local bodies responsible for managing our green and blue spaces to provide safe, accessible access to natural settings for the healthy mental and physical development of our children.
“If our findings are supported by longitudinal research that tracks people’s exposures over the entire life-course, it would suggest that further work, policies and initiatives encouraging more blue space experiences during childhood may be a viable way to support the mental health of future generations.”
Dr Leanne Martin, co-author and postdoctoral research associate at the University of Exeter’s European Centre for Environment and Human Health, added: “Water settings can be dangerous for children, and parents are right to be cautious. This research suggests though that supporting children to feel comfortable in these settings and developing skills such as swimming at an early age can have previously unrecognised life-long benefits.”
