Horses in Cornwall take to the sea to cool down and exercise

Horses and their riders have been taking to the sea in Cornwall to cool down.

Chris Cooke, from Cornish Sea Horses, said: "When you see astronauts feeling weightless in space, it's a bit like that."

"It's exercising all their muscles. Race horse trainers have been using this for years.

"We do it because it's fun for us and the horses," he added.
