THE WEATHER IS HOT, BUT THE WATER IS COLD.
The Met Office have issued an ‘Extreme Heat’ Amber warning for Monday and Tuesday this week, so if you are heading for the coast, or inland waters to cool off, please remember the dangers of Cold Water Shock.
This can happen in water below 15°C (UK sea temperature rarely gets above this even in the summer, around the Somerset coast, today is just 14°C, and can seriously affect your breathing and movement. UK fresh water temperatures are generally are a couple of degrees cooler, so the risk is always there.
What does Cold Water Shock do to you?
It causes the blood vessels in the skin to close, and heart rate is increased so the heart has to work harder, raising your blood pressure. This can therefore cause heart attacks, even in the relatively young and healthy. Cold water immersion also causes an involuntary gasp for breath, uncontrollable breathing rate increase, and a feeling of panic, increasing the chance of inhaling water directly into the lungs - enough to start the drowning process.
You can counter the effects of Cold Water Shock.
The initial effects pass in less than a minute or two so don’t try to swim straight away. Relax and FLOAT TO LIVE - float like a starfish, tilt your head back and keep your ears just submerged, gently move your arms and legs to keep afloat and try to keep calm - then call for help or swim for safety if you’re able.
Float to Live has saved lives - please remember the message, share it with family and friends, and treat water with respect.
