Standing Desk Study Shows Negative Effects on Cardiovascular Health
A recent study led by a West Virginia University epidemiologist has shed light on the potential negative effects of too much standing during work on cardiovascular health. The research, which focused on the use of sit-stand desks to reduce sedentary behavior and lower blood pressure, found that while alternating between sitting and standing at work can decrease sedentary behavior, it has no significant effect on lowering blood pressure.
The clinical trial involved participants with hypertension who were provided with sit-stand desks and encouraged to stand for 15 to 30 minutes each hour, as well as take a walking break every hour. Despite the decrease in sedentary behavior observed in the participants, there was no improvement in blood pressure measurements.
According to Bethany Barone Gibbs, chair and professor in the Department of Epidemiology and Biostatistics at the WVU School of Public Health, the findings challenge the common belief that using sit-stand desks can help lower blood pressure. While physical activity such as brisk walking has been shown to decrease blood pressure, the study highlights the importance of considering the effects of prolonged static standing on cardiovascular health.
The researchers found that prolonged static standing may have a similar effect to sitting for long periods, as it hinders the physiological mechanism known as the muscle pump. This mechanism helps circulate blood from the legs back to the heart, and when standing still for extended periods, the blood pooling effects observed can be detrimental to cardiovascular health.
While the study did not yield the expected results in terms of blood pressure reduction, Barone Gibbs emphasized the importance of understanding what does not work in addition to identifying effective interventions for improving blood pressure. The study, published in the journal Circulation, also highlighted the potential benefits of standing outside of office hours, as more active standing during leisure time may have a positive impact on blood pressure.
Moving forward, Barone Gibbs plans to explore alternative behaviors that can be incorporated into desk work to promote better cardiovascular health. By encouraging movement at the desk, such as heel raises, using a balance board, or marching in place, the aim is to mitigate the negative effects of prolonged static standing and improve overall health outcomes.
In conclusion, while sit-stand desks have various benefits such as relieving chronic low back pain and regulating glucose levels, it is essential to consider the implications of prolonged static standing on cardiovascular health. Further research in this area is crucial to provide evidence-based recommendations for optimizing health and well-being in the workplace.
