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.
