The study was based on the answers to a mailed questionnaire of a simple random sample of respondents from two cities (Helsinki, Tampere) in Finland. Ten determinants of restorative experiences in favorite places (<or = 15 km from home; n=1089) were effective. These determinants included "immediate" use of the favorite place (duration and frequency), personal background of nature experiences (nature orientedness, nature hobbies, childhood nature experiences), and situational factors in life, which were related to stress (hassles at work and with money, satisfaction with life) and to social relations (uplifts of social relations, visiting alone vs. in company). Different variables were associated with restorative experiences in different favorite settings (extensively managed nature areas, built-up green spaces, waterside environments, exercise and activity/hobby areas, and indoor and outdoor urban areas). The concept of "favorite place prescriptions" is introduced as an analogy to "exercise prescriptions" in primary healthcare.
