Exposure to outdoor blue spaces can help improve human health by reducing stress, promoting social relationships, and physical activity. While most studies have focused on the adverse health effects of scuba diving, very few have assessed its health benefits. Moreover, when scuba diving is done in large groups with no diving instructor or pre-dive briefing, negative environmental impacts are generated and negative impacts on human health may also occur due to overcrowding, which may create stress. This is the first study to evaluate the effects of scuba diving on divers’ mental health using their diving practices to estimate the impacts on the ecosystem. In the marine-protected area of Cap de Creus and adjacent areas, we assessed the mental health of 176 divers and 70 beach users (control group) by employing a 29-item version of Profile of Mood State (POMS) questionnaires. According to the parameters associated with reduced environmental impacts, two scuba diving experiences were established. Poisson regression models were performed to assess both the contribution of the activity and diving experiences to POMS scores. Both groups (scuba divers and beach goers) reduced their POMS scores after carrying out the activities. Although no significant differences were found between beach and scuba diving activities, nor between the two different scuba diving experiences, our results showed that subjects with regular medication intake due to a chronic or psychiatric illness had a POMS reduction score significantly higher than other subjects. We conclude that both beach and scuba diving activities have positive effects for human mental health, particularly among subjects with regular medication intake.

La Conca de Tremp, situada en la comarca montañosa catalana del Pallars Jussá, es una de las áreas donde más se ha incrementado la ganadería porcina en régimen estabulado en las últimas tres décadas. Los impactos medioambientales negativos derivados de este sistema de producción ganadera son muy considerables, especialmente los relacionados con el vertido de puriñes que ha provocado un alto grado de nitrificación de las aguas. Análisis pormenorizados demuestran que el nivel de nitrificación de las aguas en la Conca de Tremp ha alcanzado un nivel muy alto, con las consecuencias que ello tiene en la salud de las personas. Atendiendo a las exigencias del desarrollo sostenible, única forma de garantizar el futuro de las comarcas de montaña, se apuntan soluciones para paliar los graves problemas generados por la intensificación de la ganadería porcina.The Tremp Basin, placed in the mountainous Catalonian region of the Pallars Jussá, is one of the areas where stabled pig cattle raising has been more increased in the last three decades. Negative environmental impacts, derived from this cattle raising production system are greatly substantial, specially the ones related to purine wastes which have caused a high degree of nitrification of the waters. Detailed analyses show that the degree of nitrification of the waters in the Tremp Basin has reached a very high level, with all that this implies for human health. Attending to the requirements of a sustainable development, which is the only way of granting a future for the mountainous regions, this paper hints at some solutions to lessen the serious problems generated by the intensification ofpig cattle raising.
