Most people look forward to retirement as a time when they can finally take up activities that they never had the time or energy to pursue before. Bust some recent studies on people in their golden years are disturbing: they suggest that retirees are more likely to suffer from depression and possibly higher rates of other diseases such as heart disease and high blood pressure. That’s why a new study of French workers is welcome news.

Led by Hugo Westerlund, a professor of psychology at Stockholm University, the study of more than 14,000 workers found lower rates of depression and fatigue(疲劳) in people after they got tired while they were still employed.

The scientists followed the employees of the French national gas and electric company for 14 years. They found in the year immediately after retirement, the volunteers reported 40% fewer depressive symptoms than they had in the year before their retirement. The researchers also found an 81% drop in reports of both mental and physical fatigue over the same time period.

Clearly, said Westerlund, much of these decrease in physical and mental fatigue can be traced back to relief from the stresses of work. The decline in depressive symptoms suggests that retirement may be having a positive mental effect, too, which may have a lot to do with the generous pensions(养老金) that French workers enjoy. Most retirees in that country still benefit from about 80% of their yearly salaries.

“The economic or financial situation in retirement is very important,” Westerlund says. “We don’t know if the decrease in fatigue and depressive symptoms is because of the removal of something bad while in work or the addition of something good while in retirement. But no matter the reason, if life in retirement is not comfortable, then we won’t see the improvements we did.”

However, in European nations like France, governments are considering changes to pension plans, which may affect retirees’ health after they leave their jobs—with less of a financial safety net, workers may no longer seem so mentally and physically happy to be out of work.
