The Met Office has forecast that there is a 70% chance of high temperatures in London between Saturday 17 June and Tuesday 20 June. The high temperatures could give rise to health risks especially for the very young, older people and people with serious illnesses.
In a heatwave people may get dehydrated and their bodies may overheat. This can cause heat exhaustion which can cause many symptoms including; headaches, dizziness, nausea, vomiting, muscle weakness or cramps, pale skin and a high temperature. It is important if you start to feel unwell to seek medical advice as soon as possible or it could develop into heatstroke which can cause serious health problems.
