Physical, mental, and physiological health benefits of green and blue outdoor spaces among elderly people.

This study investigated the influence of designed natural outdoor spaces and space type on the physical, mental, and physiological health status of elderlies. A total of 978 questionnaires were distributed among a population-based randomized sample of elderlies residing in Bandar Abbas city, Iran. Blue space users reported better health status. Park access was associated with physical and physiological health. Those participants who had cardiovascular diseases were more likely to visit the parks more often, while the people with hypertension visited the parks less often. Length of park stay positively was associated with all aspects of health status. In addition, the level of physical activity positively was associated with physical and mental health. The park organizations should work on establishing parks in shorter distances and consider the opportunity for elderlies to participate in social programs to encourage them to frequently visit the parks and increase their length of park stay.
