Standing desks under scrutiny: Study questions health benefits
In recent years, more and more people have chosen to work while standing in an attempt to counteract the negative effects of a sedentary lifestyle. Standing desks are becoming standard in many offices, and employees often spend entire days in this position. But is standing truly beneficial for our health? Recent research suggests the answer may be surprising.
A study published in the esteemed journal "International Journal of Epidemiology" provides new insights into the impact of prolonged standing on health.
Researchers from the University of Sydney conducted a detailed analysis of cardiovascular health data from 83,013 adults in the UK. This data was gathered over seven to eight years, during which time the participants' physical activity was monitored using modern wrist-worn devices.
Standing is not a cure for a sedentary lifestyle
The results of the research clearly show that prolonged standing does not offer cardiovascular health benefits.
"Standing for too long will not offset an otherwise sedentary lifestyle and could be risky for some people in terms of circulatory health," emphasises Dr Matthew Ahmadi, the lead author of the study.
Moreover, the study suggests prolonged standing may increase the risk of circulation-related diseases, such as varicose veins or deep vein thrombosis.
Sitting also poses a threat
The research notably indicates that while standing does not improve heart health, prolonged sitting also has negative consequences.
According to the research, sitting for more than 10 hours a day significantly increases the risk of cardiovascular diseases and blood pressure problems, further highlighting the need to incorporate movement into daily life.
"For people who sit for long periods on a regular basis, including plenty of incidental movement throughout the day and structured exercise may be a better way to reduce the risk of cardiovascular disease," says Prof Emmanuel Stamatakis, director of the Mackenzie Wearables Research Hub.
How to avoid the risks? Movement is key to health
In light of these findings, experts recommend avoiding prolonged periods of standing and sitting. Scientists suggest incorporating physical activity into daily routines, such as short walking breaks, using stairs instead of lifts, or having meetings on the move.
"Take regular breaks, walk around, go for a walking meeting, use the stairs, take regular breaks when driving long distances, or use that lunch hour to get away from the desk and do some movement. In Australia, we are now coming into the warmer months, so the weather is perfect for sun-safe exercise that helps you get moving," advises Stamatakis.
He also suggests that individuals step away from their desks during work breaks and ensure regular stops to stretch their legs during long car journeys.
Even short activity can help
The importance of moderate but regular physical activity was also emphasised. Studies by Dr Ahmadi and Prof Stamatakis, published earlier this year, demonstrated that even six minutes of vigorous exercise or 30 minutes of moderate activity could significantly reduce the risk of heart disease, even in those who spend most of the day sitting.
Although this study did not specifically concern standing desks, the authors note that using such furniture likely constitutes a small fraction of the time spent standing. Ultimately, the key takeaway from the research is that prolonged standing is not a healthy alternative to sitting, and regular physical activity, regardless of work position, remains the best way to improve cardiovascular health.
