Irish Water Safety - Stay within your depth when swimming in open water
Irish Water Safety is appealing to the public to stay within their depth when swimming in open water during this current spell of hot weather, following an analysis of the thirteen drownings in last year's heat wave.
The majority of drownings, 62%, occur inland where river and lake beds can be difficult to see and therefore extremely difficult to determine if you are swimming within your depth. The onset of cramp, combined with the panicked realisation that you are out of your depth can have tragic consequences and be compounded further by the muscle cooling effect of longer periods in open water. Bear in mind that in a recent analysis on drowning over the last 25 years we discovered that 32% of drowning victims had consumed alcohol so stay away from water when you have been drinking.
