At least 12 people have died in heat-related incidents since the temperature started to climb to dangerous levels.
Today was not the hottest on record despite hitting a high of 38.1C in Santon Downham - but the Met Office has warned that the worst is yet to come tomorrow.
The highest temperature ever recorded in the UK was in July 2019, when temperatures reached 38.7C in Cambridge.
The rise in temperatures has forced the UK Health Security Agency to issue a level 4 heat-health alert alongside the Met Office red warning running from Monday to Wednesday and the chief executive of the College of Paramedics has warned that the “ferocious heat” could result in people dying.
Doctors have warned of a danger to life or potentially serious illness from the blistering temperatures.
Recommended precautions include avoiding physical exercise, keeping to the shade and maintaining ventilation, drinking plenty of water and using in-date sun cream.
People have been warned against using rivers and lakes to cool off due to the dangers of swimming in open water.
Sadly, at least 12 people have died in heat-related accidents since July 7.
