The Met Office warns that temperatures of more than 30C by day and 15C by night are to be expected by people in the South East of England in the coming days. The heatwave can affect anyone, but some groups are under a higher risk of serious harm, including the very young, older people and those who are suffering of serious illnesses. The heat can multiply and worsen the heart and respiratory problems. In extreme cases, excess heat could lead to strokes which can be fatal.
