The Met Office has issued a warning about cold water shock as it extends its amber heat alerts until Sunday. Temperatures in parts of Southeast England are forecasted to remain above 20°C overnight, leading to an extended weather alert. With many people heading to open water to cool down, authorities are cautioning families about the risks at these sites, not limited to swimming.
The Royal National Lifeboat Institution (RNLI) has highlighted the serious health threat posed by cold water, which can result in cold water shock. Samantha Hughes, the National Water Safety Partner at the RNLI, emphasized the dangers of sudden exposure to cold water, which can lead to increased breathing and heart rate, potentially causing panic.
The Met Office warns that even on hot days, bodies of water in the UK can remain cold enough to trigger cold water shock, a sudden physiological response to immersion in water below 15°C. This risk applies to anyone, regardless of age, fitness level, or swimming ability.
Recent incidents, including the deaths of at least nine individuals in open water during May’s heatwave, underscore the importance of water safety. The RNLI advises individuals in distress in the water to float to stay safe. Additionally, lifeguarded beaches are recommended, and beachgoers should swim between designated flags to ensure their safety.
In response to these tragedies, a campaign called “Save Lives for Sam” has been launched by the Mirror to address the increasing drowning incidents in the UK. The public is urged to be cautious around open water during the ongoing heatwave to avoid the risks of cold water shock.
Darren Lloyd, who lost his son Jack in a water-related accident, has supported the safety campaign, emphasizing the need to raise awareness and prevent further tragedies. The current weather conditions in Britain have prompted multiple days of alerts, with record-breaking temperatures observed, leading to heightened vigilance and safety measures.
