Heat wave

Heat wave - Soaring temperatures over Europe are said to be responsible for the deaths of three swimmers, who reportedly suffered from cold water shock on beaches near Montpellier.  A 70-year-old man reportedly suffered a cardiac arrest in calm water, while a 62-year-old woman and another man, aged 75, died in similar circumstances, according to French media.  Cold-water shock is the first stage of sudden immersion into water, usually with a temperature below 15C, and can instantly affect breathing and movement. French firefighters are warning people not to swim in to water which is too cold during the hot weather and swimmers are being advised to enter the water gradually.
