Age Action is urging communities to help ensure their older neighbours remain safe and well during the cold weather.
Head of advocacy and communications at the organisation Justin Moran said cold weather can and does kill people and can be particularly challenging for older people.
“Between 1,500 and 2,000 excess deaths occur during the winter in Ireland, compared to the summer. Many of these are older people who die as a result of respiratory illness or cardiovascular disease. Snow and ice add to the problem as many may not be able to get out to buy food, fuel or medical supplies,” he said.
