The Met Office has issued a cold water shock warning after extending its amber heat alerts through to Sunday, with parts of Southeast England not expected to drop below 20°C overnight. The warning comes as many Brits seek to cool off in open water, but authorities caution that water temperatures remain dangerously low.
Cold Water Shock Risks
The Royal National Lifeboat Institution (RNLI) highlighted that cold water shock can cause a sudden increase in breathing and heart rate, potentially leading to panic. Samantha Hughes, RNLI National Water Safety Partner, stated: "It's important to remember that the water is still cold. Entering it unexpectedly can lead to cold water shock, causing a sudden increase in breathing and heart rate, which may trigger panic."
The Met Office explained that cold water shock occurs when the body is unexpectedly immersed in water below 15°C, and even on hot days, UK waters can remain cold enough to trigger this reaction. The physiological response can affect anyone regardless of age, fitness, or swimming ability.
Recent Tragedies and Safety Advice
At least nine people died in open water during May's heatwave, including 12-year-old Junior Slater. The RNLI advises that if you find yourself in difficulty, tilt your head back and float. "If you find yourself struggling in the water, remember to Float to Live: tilt your head back so your ears are submerged, relax and control your breathing," the RNLI added. "Where possible, always choose a lifeguarded beach, and swim between the red and yellow flags. In a coastal emergency remember to call 999 for the coastguard."
Cambridgeshire Fire and Rescue Service also urged the public not to jump into open water, warning of cold water shock. A spokesperson said: "We urge people to avoid jumping into open water during hot weather. While the air temperature may be high, the water is much colder, and sudden immersion can trigger cold water shock."
Personal Stories and Campaigns
The safety campaign was backed by Darren Lloyd, whose son Jack, 16, died after entering Crown Lakes in Farcet. He said: "It's incredibly difficult to speak out after losing a child, but we've done this to help others and save lives. If you are a young person watching this - you wouldn't want to put your mum and dad through this."
The Mirror has led a campaign called 'Save Lives for Sam' to prevent drowning tragedies, noting that 33 children drown in England every year—"the equivalent of a classroom of children lost." Campaigners describe drowning in the UK as an "epidemic" and a "national emergency."
Heatwave Details
Britain is experiencing its fourth consecutive day of weather alerts, downgraded to amber after three days of red warnings. The June heat record was broken on two successive days, with temperatures reaching 36.7°C in Merryfield, Somerset, on Thursday.
