Sitting all day may be linked to heart disease: research

How Your Desk Job Could be Putting Your Heart at Risk

Recent research suggests that sitting at your desk all day may increase your risk of heart disease, even if you exercise regularly in your spare time. Dr. Ezim Ajufo, a cardiology fellow at Brigham and Women’s Hospital in Boston, emphasized the importance of reducing excess sitting, regardless of physical activity levels.

Dr. Keith Diaz, an associate professor of behavioral medicine at Columbia University Medical Center, highlighted the need for further research to understand the specific risks associated with prolonged sitting and establish guidelines for what constitutes excessive sitting.

The study, published in the Journal of the American College of Cardiology, analyzed data from nearly 90,000 individuals wearing accelerometers to track sedentary and active time. The results revealed a correlation between increased sedentary time and a higher risk of cardiovascular diseases, providing a suggested threshold of no more than 10.6 hours of daily sitting.

Understanding the Impact of Prolonged Sitting

While the study’s findings shed light on the adverse effects of prolonged sitting on heart health, there are some limitations to consider. The data primarily consisted of individuals of European ancestry, limiting its generalizability to the broader population.

Although the observational nature of the study prevents causal claims, the link between excessive sitting and heart disease remains plausible. Prolonged sitting can impair muscle function, affecting blood sugar and lipid regulation, underscoring the importance of incorporating movement breaks throughout the day.

Strategies to Stay Active at Work

Merely switching to a standing desk may not suffice, as static standing fails to engage muscles effectively. Alternatives like a bike or treadmill desk, walking meetings, or regular short breaks for movement can help combat the sedentary nature of office work.

Contrary to popular belief, engaging in vigorous physical activity after a day of prolonged sitting may not fully offset its detrimental effects. While exercise remains beneficial for overall health, it may not completely negate the risks associated with prolonged sedentary behavior.

Incorporating regular movement breaks and finding opportunities to stay active during the workday are essential steps towards mitigating the negative impact of prolonged sitting on heart health. Remember, a balanced approach that combines physical activity with reduced sitting time is key to promoting cardiovascular well-being.
