Scientific studies showing how regular contact and physical activity in natural environments result in health benefits are increasingly precise and conclusive, and include many aspects related to physical and mental health. Starting from protected areas departments, many initiatives have appeared to incorporate health in the planning and management of these natural spaces, with successful results both for the improvement of the health and well-being of the people and for the conservation of the natural heritage. In recent years, numerous projects have arisen in different autonomous communities and local administrations, which show the potential of this line of collaborative work. It would be desirable to develop a joint strategy between the departments of health and nature conservation in order to enhance the indicated benefits through common projects at different scales.
