Researchers found the typical adult Brit is losing around two hours a day fretting over issues such as personal finances, health, getting old, job security and relationships.
They also found that extreme anxiety has left many Brits unable to concentrate at work, caused endless sleepless nights and even rifts with partners, 'Daily Mail' reported.
"It is a sad reality that stress is dominating our lives and having a severe impact on our work life, our quality of sleep and our personal relationships," Paul Keenan of Benenden Health said.
"The crunch comes when it begins to have a detrimental impact on our health - and 45 per cent admit stress is already doing this. Thirty-two per cent of people have even gone to the doctors because of worry or stress," Keenan said.
Concerns over low energy levels, fearing the aging process or work concerns were featured in the list of the most common worries.
Relationship concerns like whether a partner is right for them or still in love with them burden the mind of many a typical person, researchers said.
The average adult experiences six nights every month where their sleep is disturbed or the quality reduced as a result of worrying, report said.
One in four Brits feel they have a major worry they are not dealing with properly or are deliberately avoiding.
One fifth has a friend or relative who they feel is currently running away from a problem while a third of people in relationships have a big worry they have kept secret from their partner - and these were most likely to be about finance problems.
One on four people does not feel they have anyone who they are able to talk with about their problems. And three in ten bury a lot of things in order to get on with day to day life.
More than one in ten people have bank statements, bills or letters they have yet to open and they put these out of sight because they are too scared to read them.
