A recent study experts from University of Exeter assessed people’s physical and mental responses to aquariums containing different exotic fish.

They found out that the viewing aquarium displays led to noticeable reductions in blood pressure and heart rate and also improved their moods. Deborah Cracknell, PHD Student and Lead Researcher at the National Marine Aquarium said that aquariums are calming patients before all kind of surgeries.

Dr Sabine Pahl, Associate Professor in Psychology at Plymouth University, said: “While large public aquariums typically focus on their educational mission, our study suggests they could offer a number of previously undiscovered benefits. In times of higher work stress and crowded urban living, perhaps aquariums can step in and provide an oasis of calm and relaxation.”
