Prolonged sitting negatively affects cardiovascular health by promoting sedentary behavior, which is linked to various health risks, including heart disease and obesity. Sitting for extended periods can lead to decreased circulation and metabolism, increasing the likelihood of high blood pressure and cholesterol levels. Additionally, a sedentary lifestyle is associated with weight gain, which can further exacerbate cardiovascular issues. Regular movement and breaks from sitting are vital for mitigating these risks. Incorporating physical activity, such as walking or standing desks, into daily routines is essential for maintaining optimal cardiovascular health and overall well-being.
