護理師與客戶討論健康促進。下列何種生活方式調整對於預防高血壓最有效？
A nurse is discussing health promotion with a client. Which lifestyle modification is most beneficial for preventing hypertension?
- ATaking a daily multivitamin每日服用綜合維他命
- BEngaging in regular aerobic exercise✓ 正解規律從事有氧運動
- CIncreasing sodium intake增加鈉攝取量
- DReducing stress through meditation透過冥想減輕壓力
高血壓（Hypertension）的預防核心在於降低心血管負荷與改善血管內皮功能。規律的有氧運動能增強心肌收縮力、降低周邊血管阻力，並透過改善代謝與體重管理，長期穩定血壓。在生活型態介入中，運動被公認為非藥物治療的一線首選。其他選項如冥想雖有輔助效果，但其降壓實證強度不及運動；鈉攝取過多是高血壓的致病因子，綜合維他命則無直接降壓效果。
The core of hypertension prevention is reducing cardiovascular load and improving vascular endothelial function. Regular aerobic exercise enhances myocardial contractility, reduces peripheral vascular resistance, and improves metabolism and weight management, leading to long-term blood pressure control. Among lifestyle interventions, exercise is recognized as the first-line non-pharmacological treatment. While meditation provides supportive effects, its evidence for lowering blood pressure is weaker than that of exercise. Excess sodium intake is a causative factor for hypertension, and multivitamins have no direct antihypertensive effect.
