People who visit parks for 30 minutes or more each week are much less likely to have high blood pressure or poor mental health than those who don’t, according to new research by Australian and UK environmental scientists.

A study led by The University of Queensland (UQ) and the ARC Centre of Excellence for Environmental Decisions (CEED) suggests people might need a minimum “dose of nature.”

UQ CEED researcher Dr Danielle Shanahan said parks offered health benefits including reduced risks of developing heart disease, stress, anxiety and depression.

“If everyone visited their local parks for half an hour each week there would be seven per cent fewer cases of depression and nine percent fewer cases of high blood pressure,” she said.

UQ CEED researcher Associate Professor Richard Fuller said the research could transform the way people viewed urban parks.

“We’ve known for a long time that visiting parks is good for our health, but we are now beginning to establish exactly how much time we need to spend in parks to gain these benefits,” he said.

“We have specific evidence that we need regular visits of at least half an hour to ensure we get these benefits.”

“Our children especially benefit from spending more time outdoors. Kids who grow up experiencing natural environments may benefit developmentally and have a heightened environmental awareness as adults than those who don’t.”
