NORTH-EAST health bosses have urged people to take extra care of themselves and others as the cold snap intensifies.

The appeal follows a surge in the number of people admitted to hospital with serious heart and chest problems.

They want everyone to wrap up, keep warm and look out for elderly friends and neighbours.

Hospital accident and emergency departments in the North-East are already struggling to cope with hundreds of people injured after slipping on ice.

Now they are facing an increase in the number of people needing hospital treatment because of heart attacks, strokes and severe breathing problems.

In many cases, this is due to the impact of the sustained cold weather affecting the the North-East and North Yorkshire.

Last night, Yorkshire Ambulance Service warned that it has cancelled journeys for patients due to attend routine appointments at hospital clinics today because of the “adverse weather conditions”.

Ambulances in Yorkshire will only transport patients with urgent medical needs.

Sub-zero temperatures can cause mild hypothermia, which increases the risks of serious illnesses as well as the likelihood of falls.

The most vulnerable groups, which NHS bosses want to help protect, include the elderly, people with longterm health conditions such as heart, lung or kidney disease, babies and the very young, as well as people with disabilities.

There is also concern about homeless people and those living in cold, damp homes.

Martin Wilson, of NHS North-East, said: “The cold weather is forecast to be with us for a while yet and it is important that people take extra care of themselves and, most crucially, look out for those who are most vulnerable and prevent them from becoming seriously ill.”

Dr David Geddes, from NHS North Yorkshire and York, said: “To keep well during colder weather it is essential to keep warm. It is also important to take precautions before going out in wintry weather. Remember to wear sturdy shoes or boots if you go out walking to lower the risk of slips and falls. If you are travelling by car, remember to take warm clothing, water and a well-charged mobile phone in case you become stranded.”

Hospitals across the region have seen a significant rise in the number of people needing treatment for fractures.

Officials at North Tees and Hartlepool NHS Foundation Trust have appealed for people to return borrowed crutches after a big increase in demand.

Tips for staying well include: Keeping your home warm, using hot water bottles or electric blankets (but never together) to keep warm at night, eating regular hot meals, wrapping up inside and out, and keeping active to improve circulation.

People need to check that elderly neighbours are warm enough and are well stocked up with food and medicine.
