Dr Jones, a practising cardiologist, said: "We have seen a significant rise in the number of people attending emergency units with cardiac and respiratory related conditions and a corresponding rise in hospital admissions.
“For children and babies, older people and those with long term health conditions, especially those with heart and breathing conditions, there are some simple steps to take to stay healthy.
“Stay out of direct sunlight between 11am and 3am when the sun is strongest, and always use a sunscreen with a high sun protection factor. Loose, cool clothing and wearing a hat when outdoors can also help to prevent heat exhaustion and sunstroke.
“People who are physically active also need to be aware of what they can do to stay cool and hydrated. eep well hydrated, drink cold drinks such as water and fruit juice regularly and avoid tea, coffee and alcohol.
“Cool baths or showers, or splashing yourself with cold water or placing your wrists under cool running water can help if you feel you are overheating.
“Don’t forget to check up on friends, relatives and neighbours; older people and people with mobility problems are likely to be affected by the hot weather.
“Getting out in the sunshine can be a real mood-booster, but don’t forget to drink plenty of water and think about what you can do to keep well in warm weather.”
