A study by the University of Turku has revealed that changes in physical activity around the time of retirement significantly impact weight and blood cholesterol levels. The Finnish Retirement and Aging (FIREA) study utilized wearable motion sensors to track physical activity changes as workers transitioned from employment to retirement and examined the health effects of these changes.
The research found that a majority of retirees experienced a decrease in physical activity, replaced by more sleep and sedentary behavior.
