Lifestyle factors contributing to hypertension include poor diet, physical inactivity, excess alcohol consumption, and high stress levels. A diet high in sodium, saturated fats, and sugars can elevate blood pressure. Lack of exercise contributes to weight gain, further increasing the risk of hypertension. Additionally, smoking and chronic stress can negatively impact cardiovascular health. Addressing these lifestyle factors through balanced nutrition, regular physical activity, and stress management can significantly lower the risk of developing hypertension.
