Health chiefs have highlighted ways the British public can manage a potential heatwave this summer.
The Department of Health has recommended that people keep an eye on elderly or vulnerable friends and relatives, and think about how soaring temperatures might impact on them.
Those with heart conditions and respiratory problems could be particularly vulnerable to high temperatures, which in extreme case could prove fatal.
People who are susceptible to high temperatures should stay in the shade where possible and avoid going out between 11am and 3pm, the plan suggests.
Regional director of public health Yvonne Doyle said: "This year's plan encourages everyone to take practical action before a heatwave strikes. Keeping the home as cool as possible during hot weather and remembering the needs of friends, relatives and neighbours who could be at risk is essential."
The highest temperature recorded last year was 30.9C (87.6F) but this summer is expected to be warmer.
Michael Dukes of Meteogroup UK, the weather division of the Press Association, said: "We can not be definite but the indications are this year will be hotter than the two previous summers with short heatwaves with temperatures above 32C (89F), especially in southern Britain."
