週末適度補眠或可降低高血壓風險,研究顯示最佳補眠時長為1小時27分鐘

Quick Look

韓國高麗大學研究員李娜媛在歐洲心臟學會年會上發表研究指出,週末補眠平均可降低6%高血壓機率,活動量較低者降低6.9%,理想補眠時長為1小時27分鐘可降低9%風險,但過度補眠則可能增加高血壓風險。

Why It Matters

過去專家認為固定作息對健康最重要,否定週末補眠可彌補平日睡眠不足的觀點。

(中央社慕尼黑31日綜合外電報導)多年來專家警告,週末若比平日睡得多,恐怕會干擾生理時鐘,對健康帶來負面效果。但1份新研究顯示,週末適當賴床反而可能有益健康,對於預防高血壓有幫助。

英國「衛報」(The Guardian)報導,以往專家強調,若要保持健康,擁有固定的就寢和起床時間很重要,並否定週末多睡可彌補週間睡眠不足的說法。

然而,韓國高麗大學(Korea University)研究員李娜媛(Nawon Lee,譯音)醫師在本屆於德國慕尼黑舉行的世界最大心臟病學會議、歐洲心臟學會(European Society of Cardiology,ESC)年會上發表的研究顯示,平均而言,週末補眠可讓高血壓機率降低6%。

週末補眠指的是週末比平日睡眠多出的時數。這項研究在7年間追蹤4萬名韓國成年人,結果還發現,上述補眠效果在活動量較低的人身上稍微更明顯,若他們週末多睡點,罹患高血壓機率會降低6.9%。

李娜媛並指出,分析顯示,理想的週末補眠長度是1小時27分鐘,可讓罹患高血壓機率降低達9%。但若補眠過多則可能有害,例如週末若比平日多睡4小時以上,罹患高血壓機率反而更高。

睡眠不足會導致血壓無法在夜晚睡眠期間下降,造成有更大機率發展出高血壓。李娜媛也說:「睡眠不足會讓身體承受額外壓力,導致心臟和血管必須不斷更努力運作,令血壓升高。」

因此她表示,規律睡眠作息依然重要,但適量補眠可能對身體有益,「具有保護作用」,尤其對週間睡眠不足的人而言,週末補眠帶來的益處,可能勝過作息變動帶來的傷害。

李娜媛表示:「人們不必因為週末多睡一點而感到懶惰或罪惡。如果平日沒辦法睡夠,週末補眠一些,可能正是身體彌補睡眠不足傷害的一種方式。」(編譯:張正芊)
