Which lifestyle change is recommended for a client newly diagnosed with hypertension?

Reducing stress is a vital lifestyle change recommended for individuals newly diagnosed with hypertension. High levels of stress can lead to temporary spikes in blood pressure and may contribute to long-term hypertension if not managed effectively. Stress can activate the body's sympathetic nervous system, resulting in increased heart rate and narrowing of blood vessels, which can elevate blood pressure. Implementing stress reduction techniques, such as mindfulness, relaxation exercises, and regular physical activity, can help in managing blood pressure more effectively.

In contrast, increasing sodium intake and decreasing exercise would likely exacerbate hypertension rather than mitigate it. Sodium is known to cause the body to retain water, which can increase blood volume and further elevate blood pressure. Regular exercise, on the other hand, is beneficial for lowering blood pressure and improving overall cardiovascular health. Hence, the focus on stress reduction is the most appropriate and beneficial option for someone managing hypertension.
