A STAGGERING 3,200 pensioners died from illnesses caused by the cold in Yorkshire and Humberside last winter - the highest figure in five years.
And a total of 28,700 succumbed to cold-related illnesses such as pneumonia and heart attacks in England and Wales, the charity Help the Aged claims.
With more cold weather hitting the region, experts say people need to be prepared.
There is a direct link between cold weather and a higher death rate, particularly among people over 65 and others in high-risk groups - such as people suffering from long-term illnesses and diseases, mobility difficulty, young children and babies.
A drop in body temperature creates a lower immune system and people become more susceptible to heart and respiratory disease.
There is also the increased risk of injury from falls, as a person's muscles react slower when the body is cold, making tumbles more likely.
A spokeswoman for the Central and South Huddersfield Primary Care Trust, said: "The best way to keep well during winter is to keep warm.
"As the weather gets colder, we are all more likely to catch colds or flu; and if your body temperature drops then the risk of a heart attack, stroke or breathing difficulties increase.
"What you eat and drink, and exercise you take, can make a big difference. As part of keeping well, it's vital to keep your home warm and keep yourself warm when yougo out."
