Ambulance service officials reported a huge surge in calls as temperatures soared.
Between last Friday and Tuesday, the East of England Ambulance Service NHS Trust (EEAST) received more than 16,700 calls, a daily average of around 3,350.
As temperatures soared into the 30s on Tuesday, during the hottest day of the year, the service received more than 3,400 calls, almost 600 more than the previous Tuesday. In Norfolk, 497 calls were taken on the Monday and 582 on the Tuesday.
The ambulance service is still urging people to think about which NHS service they need during this period. Anyone requring medical help, which is not an emergency, should call 111, the NHS non-emergency helpline or see your GP or pharmacist.
The service has suggested the following tips to stay safe in the sun: wear loose, cool clothing, and a hat and sunglasses if you go outdoors; stay out of the sun between 11am and 3pm if you’ve vulnerable to the effects of heat; stay in touch with friends, neighbours, and relatives who may be less able to look after themselves; drink cool drinks regularly such as water and avoid excess caffeine and alcohol; wear sun cream.
