Charity Age Cymru is calling for more to be done to prevent people dying during the winter months from cold-related illnesses.
The number of winter deaths rose from 1,260 between December 2011 and March 2012 to 1,900 in the same four months 2012/13.
We know that last winter older people in Wales were more likely to have cut back on their heating and eating than those anywhere else in the UK.
Rising energy prices are likely to mean more people are put in this position again this winter and this, combined with very cold weather, could be very dangerous for many older people.
– Graeme Francis, Age Cymru
The fact that older people in our communities are risking their health because they are afraid to turn up their heat or are going without food is clear evidence that we are failing them. The fact that people actually die in these entirely preventable circumstances is our national shame.
