Social prescriptions are prescriptions (from health practitioners) that are not biomedical or overtly psychological. See, for instance, Can you prescribe nature? and Bromley-by-Bow Centre and the future of mental health treatment.
Social prescribing mostly involves a variety of activities that are typically provided by voluntary and community sector organisations. Examples include volunteering, arts activities, group learning, gardening, befriending, cookery, healthy eating advice and a range of sports.
