A recent study reveals that standing for prolonged periods at work may negatively affect cardiovascular health, challenging conventional beliefs about the benefits of staying on one's feet. Conducted on 156 workers aged 60 to 64, the study found that participants who spent more time standing or engaging in light physical activity at their jobs had worse 24-hour diastolic blood pressure readings compared to those who primarily remained seated. These findings suggest that standing for long durations without adequate breaks can lead to pooled blood in the legs, potentially impacting heart health.
The research, which focused on workers, over 80% of whom were women with non-manual jobs, utilized a precise 24-hour blood pressure measurement technique. This approach provided a more accurate assessment of cardiovascular health than previous studies. The data showed that those who stood more or engaged in light activities had poorer blood pressure readings than their sedentary counterparts. The study specifically examined how blood pressure changed over a 24-hour period depending on whether participants were sedentary or active during work, leisure time, and non-work days.
Interestingly, while replacing sitting with standing has been associated with small but statistically significant decreases in blood glucose levels and body fat, the new findings suggest that extended standing may not be as beneficial for heart health as previously thought. The researchers emphasized the importance of moderation, suggesting that individuals who work on their feet should limit standing time when possible to maintain healthy blood pressure levels.

Dr. Basel Ramlawi highlighted the established benefits of active jobs over sedentary ones, yet he also advised caution when interpreting the study's conclusions.
“I would take conclusions with a grain of salt,” – Basel Ramlawi, MD
The study's results underscore the necessity for balance in workplace activities. For those engaged in either office settings or physically demanding jobs, the key lies in combining periods of standing, movement, and necessary rest.

To mitigate the risks associated with prolonged standing, experts recommend integrating more moderately intense physical activities into one's routine. Engaging in at least 200 minutes of such activities weekly can significantly enhance cardiovascular health for sedentary workers.

For those working in environments that require standing or light movement, integrating walking meetings, regular leg-stretching breaks, and wearing compression socks could help reduce the risk of blood pooling and related vein issues.

“Taking walking or sitting breaks from stationary standing could be beneficial,” – Norha
Jooa Norha further supported these recommendations by emphasizing the significance of physical activity in maintaining healthy blood pressure levels.
“We know that physical activity is helpful in maintaining healthy blood pressure levels,” – Jooa Norha
Despite the seemingly contradictory findings, it remains crucial for individuals with active occupations to engage in consistent, moderately intense physical activities outside their work routines to ensure comprehensive health benefits.
