Which of these factors would NOT contribute to cardiovascular disease?

Regular hydration is essential for overall health and plays a significant role in cardiovascular well-being. Adequate hydration supports proper blood circulation, helps maintain blood pressure, and can improve the efficiency of the heart and other bodily systems.

In contrast, the other factors listed—obesity, smoking, and physical inactivity—are well-documented risk factors for cardiovascular disease. Obesity can lead to conditions such as hypertension and diabetes, which are closely linked to heart disease. Smoking causes damage to blood vessels and promotes atherosclerosis, significantly increasing the risk of cardiovascular events. Similarly, physical inactivity is associated with a higher likelihood of developing cardiovascular problems due to its link to obesity and other metabolic issues.

Regular hydration, on the other hand, does not have any established negative impact on cardiovascular health and is therefore not a contributor to cardiovascular disease.
