Gardaí have missed over 8,600 days of work due to mental health issues since the start of last year.
According to Freedom Of Information files released to Today FM's newsroom, the sick leave has been taken by 84 officers.
Thirty-seven Gardaí have taken sickness absence due to mental illness, such as stress and anxiety, so far this year.
They've missed a total of over 3,400 days work as a result.
Last year 47 officers were out of work due to similar issues - and they missed over 5,200 days.
Over the two years, 447 Gardaí have had psychiatric or psychological assessments with the Garda Occupational Health Service.
“Everyday being [on the] frontline, working with people who sometimes can be a danger to yourselves, you are kind of in a threat mode,” clinical psychologist Malie Coyne described.
“I mean it’s an incredibly difficult job and I suppose many people who go into that type of work might be more likely to be helpers - which means that they sometimes look after their own mental health needs less.”
An Garda Siochána told Today FM the welfare of all its staff is of paramount importance, adding it has a 24/7 independent counselling service for Garda members.
