(Telegraph) Fish tanks lower blood pressure and heart rate
Higher numbers of fish also helped to hold people’s attention for longer and improve their moods
Now a new study has shown for the first time that staring at swimming fish really does lower blood pressure and reduce heart rate.
In the first investigation of its kind, experts from the National Marine Aquarium, Plymouth University and the University of Exeter assessed people’s physical and mental responses to tanks containing varying levels of fish.
Even viewing an empty tank with just rocks and seaweed lowered heart rate by three per cent. But when fish were introduced heart rate fell by seven per cent. Watching fish also reduced blood pressure by four per cent.
Higher numbers of fish also helped to hold people’s attention for longer and improve their moods.
