Scientists from Denmark have found a link between the type of work and the risk of developing dementia. It found that workers with a profession associated with manual labor had the disorder 55 percent more often. This is evidenced by the results of a study published in the journal Medicine & Science in Sports.
The researchers concluded that physical work wears out the brain as well as internal organs, especially the cardiovascular system. Previously, it was believed that such work, on the contrary, reduces the risk of impairment of cognitive functions of the brain.
At the same time, a healthy lifestyle and playing sports halves the likelihood of illness. According to scientists, the effect of physical activity at work and stress in free time is exactly the opposite.
The study involved 4,721 Danish men. Scientists began to observe them in the 1970s, taking into account the nature of their work, body mass index, sports activities and the presence of bad habits.
According to experts, the first signs of dementia can be seen decades before the disease fully manifests itself. Thanks to the study, they say, employers will be able to prevent dementia in workers.
