Specifically, those who sit for more than 10.6 hours daily face up to a 60% increased risk of developing heart failure or dying from cardiovascular causes.

Experts recommend limiting sedentary time to under 10.6 hours per day, particularly for individuals in desk jobs, to improve heart health.

While achieving the recommended 150 minutes of moderate-to-vigorous exercise weekly can help mitigate some risks, it does not fully counteract the dangers of prolonged sitting.

The study emphasizes the importance of breaking up long periods of sitting with additional movement throughout the day to optimize heart health.

Cardiologists suggest incorporating more physical activity into daily routines, such as taking stairs, walking during calls, and using standing desks, to reduce sedentary behavior.

Prolonged sitting is linked to various health issues, including obesity, high blood pressure, type 2 diabetes, and certain cancers, as noted by the American Heart Association.

Sitting for extended periods slows circulation, weakens heart muscles, and contributes to weight gain and high blood pressure, increasing the risk of inflammation and serious diseases.

The findings indicate that even individuals who exercise regularly are at risk, as prolonged sitting can lead to serious heart health issues.

A recent study published in the Journal of the American College of Cardiology analyzed activity tracker data from over 89,500 participants in the U.K. Biobank, revealing significant cardiovascular risks associated with prolonged sitting.

For individuals with a family history of heart disease, consulting with a medical professional is advised for personalized health strategies.
