What lifestyle factor increases the risk of stroke?

Obesity and inactivity are significant lifestyle factors that increase the risk of stroke. When individuals are obese, they often experience increased blood pressure, higher cholesterol levels, and other cardiovascular conditions that can contribute to the development of a stroke. Inactivity, particularly a sedentary lifestyle, exacerbates these health issues because regular physical activity is essential for maintaining a healthy weight, improving circulation, and promoting overall cardiovascular health.

Conversely, the other options represent lifestyle factors generally associated with positive health outcomes. Regular hydration supports overall health and can help maintain optimal blood viscosity, while consistent sleep patterns are crucial for recovery and maintaining cardiovascular health. Frequent social activities can promote mental well-being and reduce stress, contributing positively to overall health. Thus, obesity and inactivity stand out as detrimental factors that directly relate to a higher risk of stroke.
