A study conducted in Finland revealed that prolonged standing at work can adversely impact employees’ 24-hour blood pressure readings. Conversely, those who spent more time sitting during their workday exhibited better blood pressure levels. The findings underscore the significance of activity patterns during work hours influencing overall blood pressure more than recreational physical activities.
It is widely recognised that regular exercise plays a crucial role in managing blood pressure. Specifically, vigorous aerobic exercises have proven effective in reducing blood pressure levels. However, day-to-day physical activities also contribute positively to this effect. Historical data have demonstrated that leisure-time physical activities provide more cardiovascular benefits than physical exertions at work, which can sometimes be counterproductive to health.
Monitoring blood pressure over 24 hours is pivotal for assessing cardiovascular health. In the context of the Finnish Retirement and Aging study (FIREA), carried out at the University of Turku, the physical activity levels of municipal workers nearing retirement were meticulously monitored. This involved using thigh-worn accelerometers that recorded movements during work, leisure, and days off. Additionally, participants were equipped with portable blood pressure monitors that provided half-hourly updates over an entire day.
According to Doctoral Researcher Jooa Norha, the cumulative readings of 24-hour blood pressure offer a more accurate representation of the cardiovascular stress endured by the body throughout different times of the day and night. Elevated blood pressure that persists across the day and fails to decline adequately during nighttime could cause blood vessels to harden and compel the heart to pump more vigorously, potentially leading to cardiovascular diseases over time.
To mitigate these risks, it is advisable to alternate between standing and sitting during the workday. Although standing desks are beneficial for breaking the monotony of sitting for long periods, excessive standing can exacerbate blood pressure problems. Individuals should integrate walking or sitting breaks into their routine to alleviate the strain caused by continuous standing.
Furthermore, the study indicates that a sedentary job does not inherently pose a risk to blood pressure if it is counterbalanced with sufficient recreational physical activity. The importance of engaging in diverse physical exercises during leisure time is emphasised for all workers, regardless of their job nature. This helps maintain overall fitness and manage work-related physical demands more effectively. Employees, particularly those in passive roles, are encouraged to ensure they participate in adequate physical activities during their free time to enhance their health and mitigate occupational stresses.
