Maybe it's the sluggishly moving fish, maybe it's the slowly waving seaweed. Whatever it is, aquariums have the power to reduce stress, new research has found.
Scientists at the National Marine Aquarium recently had the chance to study how one of its larger exhibits was affecting people while it was being slowly restocked with new fish.
They studied physiological effects the tank had on people as they looked at it, and discovered that as more fish were added, heart rates and blood pressure dropped. People reported having better moods after looking at the exhibit.
"Even watching a normal tank - the light and the movement of the artificial seaweed - was quite relaxing for people," said Deborah Cracknell, lead researcher at the National Aquarium, in a statement. "But when we added fish, it definitely did make a difference."
It's not that surprising a result - aquariums are known to be calm and enchanting places. Good evidence of that can be heard in the music from Camille Saint-Saens inspired by aquariums. But it does add to the vast body of research that says people can physically improve stress levels by escaping the grind and observing nature.
