Over 70% of people have suffered from stress at some point in their lives, according to a survey from Westfield Health.
The survey of 510 adults also found that 39% of people have taken time off due to their stress levels and 67% have not been offered any stress support services by their employer.
The research follows a study produced by University College London (UCL) earlier this year which warned that employees suffering from chronic stress have a 68% higher risk of becoming a victim of heart disease.
UCL found that anxiety damages the way the heart deals with tense situations. Further, those who reported stress had a poor "vagal tone" - impulses that regulate heartbeat - and they had higher than average levels of the stress hormone cortisol when they woke in the morning.
Jill Davies, deputy chief executive of Westfield Health, says: "Stress has a variety of causes and may be related to personal issues, ill-health or working conditions. But it is now becoming clear that when a sufferer seeks treatment for the problem, it may not only improve their mental health, but could also have a marked beneficial effect on their overall health."
