At reported volumes of nature-based physical activity in the UK, the researchers estimate exercise in nature prevented 12,763 cases of non-communicable diseases, creating annual healthcare savings of £108.7m (roughly $136 million).
Physical activity in natural environments prevents almost 13,000 cases of non-communicable (i.e., chronic) diseases a year in England and saves treatment costs of more than £100m ($125 million), a new study shows.
Using data from a representative cross-sectional survey of the English population, researchers estimated how many cases of six non-communicable diseases -- major depressive disorder, type 2 diabetes, ischemic heart disease, ischemic stroke, colon cancer, and breast cancer -- are prevented through nature-based recreational physical activity.
"We believe this is the first time an assessment like this has been conducted on a national scale and we've almost certainly underestimated the true value of nature-based physical activity in terms of disease prevention," said Dr. James Grellier from the University of Exeter Medical School. "Although we have focused on six of the most common non-communicable diseases, there are several less common diseases that can be prevented by physical activity, including other types of cancer and mental ill health."
Population-representative data from the Monitor of Engagement with the Natural Environment survey were analyzed to estimate the weekly volume of nature-based recreational physical activity by adults in England in 2019. Researchers used epidemiological dose-response data to calculate incident cases of the six non-communicable diseases prevented through nature-based physical activity, and estimated associated savings using published costs of healthcare, informal care, and productivity losses.
In 2019, 22-million adults in England ages 16 years or older visited natural environments at least once a week. At reported volumes of nature-based physical activity, the researchers estimate this prevented 12,763 cases of non-communicable diseases, creating annual healthcare savings of £108.7m (roughly $136 million).
"For people without the access, desire, or confidence to take part in organized sports or fitness activities, nature-based physical activity is a far more widely available and informal option," Grellier said. "We believe that our study should motivate decision-makers seeking to increase physical activity in the local population to invest in natural spaces, such as parks, to make it easier for people to be physically active."
