Name a lifestyle factor that can contribute to hypertension.

High sodium intake is a significant lifestyle factor that contributes to hypertension. Sodium can lead to an increase in blood volume, which places additional strain on the heart and blood vessels, resulting in elevated blood pressure. When the body retains more water due to high levels of sodium, it further increases the fluid in the circulatory system, exacerbating the condition.

In contrast, regular exercise generally helps to lower blood pressure and improve cardiovascular health. Low alcohol consumption is associated with a reduced risk of hypertension compared to excessive alcohol intake, which can lead to high blood pressure. Similarly, a diet rich in potassium is beneficial as it helps to counteract the effects of sodium and can aid in lowering blood pressure.
