Over 300 people are expected to contact Pieta's crisis helpline this Christmas Day.
The number of people reaching out to the national suicide prevention charity is set to rise by 15 per cent this December, exceeding 10,000 calls and texts.
The charity is appealing to people to light candle in their window at 7 o'clock this evening and reach out to a loved one, as part of their 'Hope Over Silence' Christmas campaign.
Pieta CEO Stephanie Manahan says it can be a very tough time for many.
"Instead of a moment of silence, we're encouraging people to reach out and talk to one and other.
"Check in with a friend, check in with a family member, check in with a neighbour and see how they're doing.
"Often we light candles for a silent memorial, but today we're really suggesting that people light their candle and they really reach out to one another."
