West Midlands Ambulance Service said it was also taking extra steps – anticipating more callouts when England plays Norway on Saturday night.
This includes additional frontline ambulance crews, more 999 call assessors and increased numbers of officers and ambulances on shift.
The service is expecting an increase in heat-related illness, dehydration and medical emergencies.
Meanwhile, Shropshire, Telford and Wrekin Community and Hospitals NHS Group said it had its highest week of emergency department attendances on record last week, “partly as a result of the impact of the heatwave the week before”.
A spokesperson for University Hospitals Birmingham, which runs Good Hope, Heartlands, Queen Elizabeth and Solihull hospitals, said they were seeing cases of severe heatstroke.
“The Trust has not stepped activity down due to the extreme heat and has in place its heatwave plans to maintain the safety and comfort of our patients and colleagues,” they said.
“We encourage our communities to follow the very good advice to stay safe by staying in the shade, staying well hydrated, looking out for their vulnerable friends and neighbours, do not swim in open water or places without a lifeguard present, and use sun protection if braving the sun.”
