For years, the message has been loud and clear: sitting is bad for your health. Prolonged sitting has been linked to a higher risk of cardiovascular disease, obesity, and even early death. This has led many companies and offices to adopt standing desks in an effort to encourage employees to stay on their feet and improve their overall wellness. But what if sitting isn’t as harmful as we’ve been led to believe? A recent study led by Jooa Norha at the University of Turku suggests that sitting for extended periods might actually have some health benefits—at least in certain circumstances.
The Growing Concern About Sitting
Multiple studies over the past decade have continuously highlighted the dangers of prolonged sitting, especially for office workers and those with desk jobs. Research from Simon Fraser University, for example, found that sitting for six to eight hours a day increases the risk of early death and heart disease by 12 to 13 percent. When people sat for more than eight hours per day, the risk increased by up to 20 percent. These alarming findings have led to widespread recommendations to reduce sitting time, with standing desks becoming a popular solution.
The prevailing belief has been that standing more frequently during the day improves circulation, boosts metabolism, and decreases the risk of conditions like diabetes and heart disease. But despite the popularity of standing desks, this new study presents an entirely different perspective, challenging the long-standing narrative.
What Does the Latest Study Say?
The study conducted by researchers at the University of Turku focused on 156 aging workers in Finland, with an average age of 62. The researchers were interested in understanding the effects of different types of physical activity—whether sitting, standing, or light movement—on the participants’ cardiovascular health.
The results were surprising. Contrary to what many might expect, the study found that individuals who spent more time sitting during their work hours had lower diastolic blood pressure levels. This is significant because lower diastolic blood pressure is associated with a healthier cardiovascular system. In fact, the study highlighted that a more nuanced view is needed when assessing the health impacts of sitting.

The Physical Activity Paradox
A key concept explored in the study is what researchers call the “physical activity paradox.” The paradox suggests that not all physical activity is equally beneficial, particularly when it occurs in the context of work. While exercise during leisure time is widely considered to have numerous health benefits, sedentary work hours do not necessarily have the same harmful effects as long as the activity level remains low and well-managed.
The study found that people who spent a lot of time standing or engaging in light physical activity exhibited less favorable blood pressure patterns. Specifically, standing and light activity were linked to disturbances in nocturnal dipping, a process where blood pressure naturally drops during sleep. If blood pressure doesn’t dip sufficiently at night, it can contribute to the stiffening of blood vessels and place extra strain on the heart, leading to an increased risk of cardiovascular disease over time.
Sitting, Standing, and Your Heart Health
The research from the University of Turku suggests that the relationship between sitting, standing, and heart health is far more complex than previously thought. While sitting for extended periods may not be as detrimental as once believed, it is still essential to find a balance. Long stretches of continuous sitting without adequate breaks or movement can still have negative impacts on metabolism and cardiovascular health. Therefore, it’s crucial to incorporate regular movement throughout the day, whether that means standing up, walking around, or doing light stretching.
For those using standing desks, the study implies that simply standing for long periods isn’t enough to offset potential health risks. In fact, standing for extended periods without sufficient rest or breaks can lead to unfavorable blood pressure patterns, which can strain the heart in the long run.
Practical Takeaways from the Study
- Take Regular Breaks: Whether you’re sitting or standing, it’s essential to incorporate movement throughout the day. Stand up, stretch, or take a short walk every 30 minutes to an hour to keep your blood circulating and your muscles engaged.
- Balance Sitting and Standing: If you use a standing desk, remember to alternate between sitting and standing. Don’t stand for long periods without moving, as this can lead to disruptions in blood pressure regulation.
- Focus on Physical Activity Outside of Work: The study emphasizes the importance of physical activity during leisure time. Regular exercise outside of work hours, such as walking, running, or strength training, is essential for overall heart health.
- Monitor Your Blood Pressure: Keeping track of your blood pressure and seeking medical advice when necessary is vital, especially if you spend long hours working. Maintaining healthy blood pressure levels is one of the most effective ways to reduce cardiovascular risks.
- Rest is Key: Just as physical activity is important, so is adequate rest. Make sure you’re getting quality sleep, as this is when your body recovers and your blood pressure naturally dips.
Rethinking the Standing Desk Craze
While standing desks may still offer benefits, particularly for reducing the risks associated with sitting for hours on end, this study challenges the idea that standing is always better for your health. Sitting, when combined with proper movement and breaks, may not be as harmful as it’s often portrayed. What’s clear is that balance is key—regular movement and attention to blood pressure, rest, and overall activity levels are all crucial for long-term heart health.
This new perspective doesn’t necessarily mean abandoning standing desks, but it calls for a more thoughtful approach to how we work, move, and rest throughout the day. Ultimately, the best strategy is to find a comfortable balance between sitting, standing, and physical activity to ensure a healthy, productive workday.
