The call follows a YouGov study published on World Sleep Day that found that over a third of workers have sleepless nights due to financial difficulties and debt.
Jim Goodchild from Christians Against Poverty told Premier how sleep loss can be a good sign that help is needed.
"It's natural sometimes... if we have something difficult to perhaps have a night or two where we struggle to sleep," he said during Premier's News Hour.
"But if that's a persistent thing - that our worries are getting on top of us - it's really important that people seek the help that they need."
The NHS warns the mental effects after several sleepless nights can be serious, with a risk to wellbeing as well as effectiveness at work.
The research conducted on behalf of credit information provider, Equifax, also found that sleeplessness has the biggest impact on people earning between £30,000 and £34,999 per year, with 65 per cent of this group saying it has negatively affected their performance at work.
Workers in the £10,000 to £14,999 bracket were least likely to be worried about poor performance at work as a result of sleeplessness.
Goodchild highlighted the importance of Christians helping people struggling financially.
He explained: "A lot of people feel a real stigma around talking about money and their finances and financial difficulties.
"I think the thing that we can do if we know someone who is struggling with it is to be there alongside them - don't judge. Just really help people to understand they can get help and that it's not a reflection on them if they're struggling with their finances."
