A tourist nearly drowned at Los Cristianos beach within an hour of someone dying in the water at Playa de Troya (link) this lunchtime. This second incident today involved an 84-year-old man who suffered a cardiac arrest in the water at a quarter to one, but on this occasion, thankfully, lifeguards and paramedics were able to resuscitate the bather at the scene. After he had been stabilized, he was transferred to Hospitén Sur where his condition is said not to be serious.
As I’ve said before, cardiac arrest in the sea is a symptom of cold water shock, which can affect people even with water temperature of up to 25º, it’s not just freezing water that is dangerous, and the water around the Canaries’ doesn’t get above 24°C (75°F) even in August. And so, regardless of the time of year, even in high summer, Tenerife’s waters are technically cold. Bathers can get into difficulties within five minutes.
To be specific about symptoms, normal body temperature is 98.6º; shivering begins when the body temperature lowers to approximately 96.5º; amnesia and coordination problems begin to set in at approximately 94º, unconsciousness at 86º, and death, normally from cardiac arrest, at approximately 79º … and 79º is 4º above our normal high season water temperatures!
