Ambulance bosses are urging people to take extra care in and around open water during the warm weather following the death of a Doncaster man.
The news comes after Matthew Mellor. 27, drowned in the old quarry off Hurst Lane, Auckley after going swimming with friends on Monday.
Every year Yorkshire Ambulance Service is called to incidents across the region where people have attempted to cool off by swimming in open water and then get into difficulty.
Vince Larvin, Locality Director of Emergency Operations at the Trust, said: “Yorkshire’s many waterways are popular destinations for people during the summer months, which can make them dangerous places for those who don’t understand the risks they are taking.
“It may be very appealing to jump into the water to cool off on a warm summer’s day but people need to be aware of how dangerous this really is. Water can look calm on the surface but contain unseen debris and, rivers in particular, can have treacherous undercurrents. The temperature of deep water is much colder than people would expect and, even on a hot summer’s day, rarely gets above freezing.
“The near-freezing temperature of deep water is cold enough to take your breath away, which is the body’s natural reaction and cannot be controlled, possibly leading to panic and drowning. Cold can also make your arms and legs numb which means you can’t control them to swim and can also lead to hypothermia - a serious reduction in body temperature - which can cause heart failure.
“Lives have already been lost this year across the UK and we don’t want to see anyone else hurt or injured so the message is simple; enjoy the summer, stay out of open water and stay safe!”
