Occupational Hazards: THESE 5 Physically-Demanding Jobs Are Most Likely To Cause Dementia

Physically demanding jobs could pose a greater risk of contracting dementia, the loss of cognitive functioning like thinking, remembering, and reasoning to such an extent that it interferes with a person's daily life and activities, according to new research. The study, conducted by the Norwegian National Centre of Ageing and Health, Columbia Mailman School of Public Health, and the Butler Columbia Ageing Center found that those labouring at physically exhausting jobs for a long time could be at greater risk of the brain robbing disease.

Study says people working in few jobs that include very high levels of activity are at greater risk of dementia

New Delhi: Experts have always stressed the need to be more physically active to stay fit and healthy – both physically and mentally.
However, a new study has said that people working in few jobs that include very high levels of activity could be at greater risk of contracting dementia, the loss of cognitive functioning like thinking, remembering, and reasoning to such an extent that it interferes with a person's daily life and activities.
Many people with dementia are not able to control their emotions, and their personalities also change distinctively.
The research, conducted by the Norwegian National Centre of Ageing and Health, Columbia Mailman School of Public Health, and the Butler Columbia Ageing Center found that those labouring at physically exhausting jobs for a long time could be at greater risk of the brain robbing disease.
The top five jobs, according to the study authors are:
  • Salespersons
  • Nursing assistants
  • Care assistants
  • Crop farmers
  • Animal producers
"Consistently working in an occupation with intermediate or high occupational physical activity was linked to an increased risk of cognitive impairment, indicating the importance of developing strategies for individuals in physically demanding occupations to prevent cognitive impairment," the authors wrote in the study.
According to the study, physically demanding jobs included those that "require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials".
According to the Alzheimer’s Association, dementia is caused by a variety of diseases that cause damage to brain cells which interferes with the ability of brain cells to communicate with each other. When brain cells do not communicate normally, thinking, behavior, and feelings are affected greatly.

How does your job cause dementia?

According to the study, physical stresses and demands hurt brain health in older ages, thereby increasing the risk of impairment later in life.
Also, since these high-pressure demands do not give much time for a person to rest and recoup, it could lead to ‘wear and tear’ of both the body and brain. In the above-mentioned jobs, workers usually stand for long hours, run around, work for more than the designated time, and even do not get many off days.
“Our work also highlights what is called the physical activity paradox – the association of leisure time physical activity with better cognitive outcomes, and how work-related physical activity can lead to worse cognitive outcomes,” said the study’s lead author Vegard Skirbekk, a professor of Population and Family Health at Columbia Public Health.
He observed that the pre-clinical period of dementia may start up to two decades before the onset of main symptoms.
“Our results particularly underscore the need to follow up on individuals with high lifetime occupational, and physical activity as they appear to have a greater risk of developing dementia,” Dr. Skirbekk noted.
