The Canal & River Trust is urging people to stay out of the water this summer.

As the temperature heats up, the temptation to cool off in a local waterway increases, but so do the dangers.

Of the 400 people who drown in the UK every year, more than half happen at inland waters such as canals, rivers, lakes, quarries and reservoirs.

The risks include low temperatures which can cause the body to go into cold shock and even hypothermia, drawing the blood away from muscles which can lead to drowining.

Mike Marshall, of the Canal & River Trust said: “We always urge parents to make sure their children know how to stay safe.

“Canals and rivers in Yorkshire may look inviting on a hot summer’s day, but any open body of water can pose a hazard as the water can often be extremely cold and can bring on cramps in even the strongest swimmers. “You just can’t train your body for the effects of the cold water and the other hidden dangers lurking beneath the surface like reeds or rubbish which swimmers could get caught up in.”
