A recent study from the University of Sydney has challenged a widely accepted belief: that standing more frequently throughout the day can improve cardiovascular health. This idea has gained popularity in recent years, especially with the increased use of standing desks in work environments. However, the results of this research reveal that simply replacing sitting time with standing does not have the positive effects many had hoped for on heart health.

The research followed more than 83,000 adults and measured the effects that prolonged standing had on their cardiovascular health. The researchers used physical activity monitors to accurately measure the time participants spent sitting, standing, and moving. Unlike previous studies, which relied on questionnaires and self-reports, this study provided a more precise assessment of participants' daily habits.

The study found that instead of improving cardiovascular health, standing for long periods without movement could increase the risk of circulatory problems, such as the development of varicose veins and deep vein thrombosis (DVT). Deep vein thrombosis is a serious issue that occurs when a blood clot forms in the deep veins, usually in the legs, which can lead to severe complications if the clot travels to the lungs.

The lead author of the study, Dr. Matthew Ahmadi, emphasized that "standing for long periods does not offset a sedentary lifestyle and, in fact, could be harmful for some people in terms of circulatory health." This means that those who have turned to standing while working to improve their health may not be getting the benefits they expected.

The researchers also clarified that this study should not be interpreted as a recommendation to return to long periods of sitting. Instead, they recommend incorporating more movement into daily routines, such as getting up and walking periodically, taking active breaks during work, and ensuring regular exercise. "Movement is key," said Dr. Emmanuel Stamatakis, another author of the study, who suggested taking any opportunity to walk or move throughout the day as a more effective way to improve cardiovascular health.
