Nature-based group activities can reduce loneliness, improve sleep and cognition, and increase a sense of connection to nature in older adults living in long-term care (LTC) settings, according to a study from the University of Helsinki and HUS Helsinki University Hospital.

For the study, the researchers trained 52 LTC group instructors in nature-based practices, then randomized 319 older adults who were experiencing loneliness into two groups, one of which took part in the nature-based group activities. Participants had an average age of 83, and more than half had memory disorders.

The researchers were surprised by the positive results despite the fact that conditions for nature-based activities were sometimes challenging. All participants traveled to excursions once a week over nine weeks in wheelchairs and by accessible taxis. Activities over a longer duration, researchers noted, would likely have bolstered the outcomes.

"Frail older adults have a great deal of resources, and by boosting those we support their wellbeing and health,” said the study's lead researcher, Kaisu Pitkälä, University of Helsinki. “More than half of LTC residents experience loneliness, a risk factor comparable with tobacco and obesity for health and memory. Loneliness is not something you can see on the outside; you have to ask older adults about it."

The study is part of the European Union-funded RECETAS project, investigating nature-based experiences across six countries.
