Cold Water Safety: Risks and Precautions
Understanding Cold Water
Definition: Cold water is any water temperature below 15 degrees Celsius.
UK Temperatures: UK and island water temperatures average just 12 degrees Celsius, with rivers like the Thames being even colder, even in summer.
Risk: Cold waters can render you helpless within seconds.
Effects of Cold Water
Cold Water Shock: Causes skin blood vessels to constrict, increasing blood flow resistance.
Increased Heart Rate: Cold water shock elevates heart rate, straining the heart and raising blood pressure.
Involuntary Gasping: Sudden skin cooling triggers an uncontrollable gasp for breath.
Panic Response: These reactions induce panic, heightening the risk of inhaling water into the lungs.
Drowning Risk: Just half a pint of seawater in the lungs can lead to drowning without immediate medical care.
Dealing with Cold Water Shock
Stay Calm: If unexpectedly in cold water, try to stay calm; initial shock subsides in under a minute.
Don't Swim Immediately: Avoid swimming right away; instead, relax or float on your back to catch your breath.
Hold onto Something: If possible, hold onto an object to help you stay afloat.
Call for Help: Keep calm and call for assistance or swim to safety if feasible.
Precautions for Cold Water Activities
Check Conditions: Prior to swimming, assess water and weather conditions at your destination.
Appropriate Attire: Wear a wetsuit suitable for the water temperature and activity duration.
Use a Flotation Device: Employ a flotation device to increase survival chances during initial shock.
