Brits have been warned that swimming in cold water increases could increase the risk of a silent killer.
Fatal cardiac arrest and hypothermia risks, despite other health benefits can all occur from swimming in cold water, according to a senior British Heart Foundation (BHF) spokesperson.
Many swimmers have sought a refreshing dip during recent warm weather, yet unfortunately water temperatures remain dangerously low as 14 people have died in waters around the UK so far this year already.
