Does standing at work have hidden implications for your cardiovascular health? A new study from the University of Turku’s Finnish Retirement and Aging (FIREA) project suggests that the answer might not be as straightforward as we think.
Researchers examined the relationship between workplace activity and 24-hour blood pressure, shedding new light on how our daily routines influence long-term heart health.
What does the study reveal about standing and blood pressure?
The study tracked the physical activity of municipal employees nearing retirement using advanced thigh-worn accelerometers. Blood pressure was monitored every 30 minutes over a 24-hour period using portable devices.
Surprisingly, prolonged standing during work hours was linked to higher 24-hour blood pressure, while spending more time sitting at work correlated with better outcomes for blood pressure.
According to Doctoral Researcher Jooa Norha,
“Rather than any single measurement, 24-hour blood pressure is a better indication of how blood pressure stresses the heart and blood vessels throughout the day and night. If blood pressure remains slightly elevated during the day and doesn’t decrease adequately at night, it can stiffen blood vessels and overwork the heart, eventually contributing to cardiovascular disease.”
How does workplace activity compare to leisure exercise?
The findings align with earlier research that physical activity at work—including prolonged standing—may be less beneficial for cardiovascular health compared to leisure-time exercise.
This may be because standing boosts circulation to the lower limbs by constricting blood vessels and increasing the heart’s pumping effort, potentially raising blood pressure.
Striking a balance between standing and sitting
While standing desks are often recommended for a more dynamic office environment, the study suggests moderation is key.
“A standing desk can provide a nice change from sitting at the office, but too much standing can be harmful. It’s a good idea to take breaks by walking every half hour or alternating between sitting and standing throughout the day,” advises Norha.
Don’t forget recreational exercise
The researchers also emphasized that sedentary work isn’t inherently harmful if balanced with sufficient recreational physical activity. Regular exercise, especially vigorous aerobic activities, is vital for maintaining cardiovascular health and managing work-related physical strain.
“Employees with sedentary jobs should prioritize staying active during their leisure time,” Norha explains.
“On the other hand, those with physically demanding roles should also engage in diverse leisure activities to improve overall fitness and reduce the impact of work-related strain.”
A fresh perspective on workplace wellness
These findings highlight the nuanced relationship between workplace activity and cardiovascular health, challenging the notion that more movement at work is always better.
The research underscores the importance of striking a balance between standing, sitting, and recreational exercise to maintain a healthy heart.

For those reconsidering their office setups or daily routines, this study serves as a valuable reminder: when it comes to your health, balance is everything.
