Persistent High Blood Pressure May Be Linked to Chronic Stress and Poor Sleep
Quick Look
- Chang Chia-ming suggests that stubborn high blood pressure may stem from the sympathetic nervous system being overactive due to chronic stress and lack of sleep.
- He advises checking for sleep apnea, kidney issues, insulin resistance, and other factors if blood pressure remains uncontrolled despite medication.

Why It Matters
High blood pressure is not solely caused by excessive salt intake or vascular aging. Dr. Chang Chia-ming, Chairman of the Precision Preventive Medicine Society, cites research indicating that many cases of stubborn hypertension are related to the brain's sympathetic nervous system being in a constant 'alarm mode'.

〔健康頻道／綜合報導〕高血壓不一定只是鹽吃太多或血管老化造成。精準預防醫學會理事長張家銘引述研究指出，很多頑固高血壓，問題不只在血管，可能是大腦交感神經一直處在「警報模式」。若血壓反覆偏高，甚至吃藥後仍控制不佳，除了規律服藥外，也應檢視是否有睡眠呼吸中止、腎臟問題、胰島素阻抗、壓力過大等問題。
張家銘於臉書專頁「基因醫師張家銘」發文分享，有些民眾一忙、一累、一睡不好，血壓就往上跑。這時候可能得推測，身體是不是太久沒有真正放鬆？交感神經是不是一直開著？我們的身體像一台車，油門一直輕輕踩著，時間久了，血壓自然很難平穩。
張家銘說明，大腦裡有一些負責調控自律神經的區域，會接收很多身體訊號，包括壓力、睡眠、發炎、鹽分、血糖、荷爾蒙，以及整體代謝狀態。當大腦感覺身體好像不太安全、負擔太大，就會啟動交感神經，讓身體進入比較警戒的狀態。交感神經一啟動，心跳會變快，血管會收縮，身體就會把血壓拉高，讓血液和能量趕快送出去。
他接著說，當民眾工作壓力、睡不好、慢性發炎、血糖不穩和代謝失衡情況長期累積下來，大腦就可能覺得身體在警戒狀態，交感神經也不容易安靜下來。當大腦一直以為身體還在「需要備戰」，這個警報模式開太久，血壓就很難真正穩定下來。
張家銘提醒，若民眾已服用降血壓藥物卻仍控制不佳，不要自己停藥，也不要自己亂換藥，建議進一步檢查是否存在睡眠呼吸中止症、腎臟疾病、荷爾蒙異常、胰島素阻抗、慢性發炎或自律神經失衡等問題。這些問是一旦未被揪出來，血壓就可能一直反覆。
張家銘強調，高血壓並非單純的數字問題，而是身體整體健康狀態的反映。除了依照醫囑治療外，不妨從運動、睡眠、壓力及飲食等生活習慣著手，找出血壓升高的根本原因，才能真正維持血壓穩定。
