Water dangers

Sir — Carol Drinkwater (an actor in a long-running vet saga from years ago) comes to mind with this awful sweaty weather. You could not give or get better advice than to drink water. It gives life but can also take life if we are careless when swimming or dipping in it. God knows there are so many warnings, but they are not heeded and the drownings make sad news.
