Which of the following is a health risk associated with a sedentary lifestyle?

A sedentary lifestyle is characterized by prolonged periods of low physical activity, which can lead to various health issues. One significant health risk associated with inactivity is the development of Type 2 diabetes. This condition occurs when the body becomes resistant to insulin or doesn't produce enough insulin, leading to high blood sugar levels. A lack of physical activity can contribute to weight gain and elevated blood sugar levels, both of which are risk factors for Type 2 diabetes. Regular physical activity helps improve insulin sensitivity, control weight, and reduce the likelihood of developing this chronic disease.

In contrast, the other options—such as increased metabolism, low blood pressure, and improved bone density—are typically associated with a physically active lifestyle rather than a sedentary one. For example, regular exercise tends to increase metabolism and enhance cardiovascular health, leading to potentially lower blood pressure and improved bone density. Thus, the association of sedentary behavior with the risk of Type 2 diabetes underscores the importance of maintaining an active lifestyle to mitigate such health risks.
