Summer Sun
As the Summer Sun graces us with its presence across the British Isles, it releases the inner child in most of us. Some people enjoy the intensity the heat brings which lures us to the water. There are some hidden dangers that hide & lurk beneath the surface. Whilst an attractive appearance the temperature of the surrounding waters are testing to say the least. Sudden exposure can cause cold water shock, a condition that can be deadly. It is important to enjoy the water safely & understand the risks
So What Is Cold Water Shock?
It occurs when the body unexpectedly enters the water, temperatures are under 15 degrees celsius. Because the cold water causes the blood vessels to constrict (vasoconstriction), limiting blood flow. Placing stress on the heart causing the blood movement to slow down. With sudden cold air being brought into the lungs this can cause the diaphragm to paralyze. This which can lead into respiratory & cardiac arrest through drowning
Treatment For Cold Water Shock
Upon immersion the cold effect usually passes within around 60 seconds, it is vital to remain still. Positioning yourself like a starfish in the water & float on the surface. Once passed attempt to gently swim to a hard surface and remove yourself from the water. Once removed from the water remove any damp clothing and create friction an warm up gently. Be prepared for CPR to start.
Prevention of Cold Water Shock
Suitably equipped & staffed which should include flotation vests, wetsuits & appropriate medical cover. Acclimatisation should be achieved before participating in any water based activities. This also aids in prevention of hypothermia and participants should be competent swimmers. First aid training is to be delivered to all staff prior to the activity commencing. This should include CPR & defibrillation training. Regular breaks should be took because this prevents dehydration.
