Staff in the trust’s accident and emergency department are warning people to stay safe in the sun.
Consultant Andy Simpson said: “We are urging people to stay safe in the sun. There has been an increase in the number of people attending the accident and emergency department at the University Hospital of North Tees due to the hot weather.
“The department has been dealing with sunburn and dehydration, which could be easily avoided.
“People are reminded to apply a high sun protection factor sunscreen and make sure they drink lots of water if they are in the sun. Older people and young children are especially vulnerable, so they should stay in the shade.
“We are seeing more children with minor injuries, especially as they are more active during summer.
“But it isn’t just children who are at an increased risk during the hot weather. We also see more adults as a result of dehydration and drinking alcohol.
“If you or your child has sustained a painful injury, please remember to take pain killers.
“People need to be careful and remember that accident and emergency should as its name suggests be used for serious accidents and emergencies.
“If you have a minor illness or injury, please make use of your GP, walk in centre or pharmacy and have a well-stocked medicine and first aid cabinet at home.”
