People across Calderdale are being urged to stay safe in the sun
Health experts say very young children, the elderly and people with long-term health conditions are most at risk of health problems when the weather is very hot.
The heat can make heart and breathing problems worse as well as heat exhaustion, leading to dizziness, nausea, a high temperature, confusion, sleepiness and intense thirst.
The West Yorkshire Resilience Forum – made up of a number of health, local authority and emergency services – is urging people to take steps to reduce their risk of ill-health, accident or injury in the coming months.
Forum manager Chief Inspector Nicola Heppenstall said: “Whenever the sun comes out, people across the UK tend to make the most of it.
“Although not all problems are avoidable we’re urging people to take extra care in the hot weather, especially when local people might be out enjoying Olympic Games events.
“Each year thousands of people from West Yorkshire end up with heatwave-related injury and illness.
“Common ailments include dehydration, sunstroke and barbecue-related burns. Most of the time these illnesses could be prevented by taking a few simple precautions.”
The forum is advising people to stay hydrated, keep out of the sun and be barbecue safe
In August 2003, temperatures hit 38C during a nine-day heatwave - the highest recorded in the UK. Up to 3,000 more people than average died due to the weather.
