藥師提醒:工作勞動無法取代運動,休閒運動降低失智風險24%,職場體力勞動卻增加20%

Quick Look

藥師簡詩敏引用《刺胳針公共衛生》統合分析指出,休閒運動可降低約24%失智風險,而職場高體力勞動則與失智風險增加20%相關。她解釋,工作勞動缺乏結構性恢復、長時間靜態負荷及心理壓力,無法替代具計畫、有結構的運動,並提供五大工作族群補足運動的建議。

Why It Matters

世界衛生組織曾將身體活動定義為肌肉收縮消耗熱量的行為,但運動需具備計畫、結構、配速且以增進體適能為目的。簡詩敏引用最新統合分析,追蹤超過420萬人,比較休閒運動與職場體力勞動對失智風險的影響。

〔健康頻道/綜合報導〕上班整天走路、搬東西,甚至每天步數破萬,未必能取代真正運動。藥師簡詩敏指出,最新刊登於《刺胳針公共衛生》的統合分析,追蹤超過420萬人後發現,休閒運動能降低約24%的失智風險;反觀職場上的高體力勞動,卻與失智風險增加20%呈現相關。她提醒,關鍵可能不在於「有沒有動」,也不代表勞動本身會傷腦,而是工作機械性重複、較低的工作自主權與環境壓力所致。

每天流汗勞動的人,到底健康還是不健康?簡詩敏於臉書粉專「簡詩敏|藥理詩詩」與網站發文表示,早在40年前世界衛生組織曾定義:「身體活動」只要肌肉收縮消耗熱量就算,如巡房、端盤子、搬貨都算;但「運動」必須具備有計畫、有結構、有配速,且以增進體適能為目的。因此,工作上的動,缺乏訓練不可或缺的「漸進負荷」與「完整休息」。

請繼續往下閱讀...

簡詩敏進一步說明,最新刊登在《刺胳針公共衛生》、追蹤超過420萬人的統合分析也發現,休閒運動可降低約24%失智風險;職場上的體力勞動,卻與失智風險增加20%呈現相關。不過,這不代表勞動本身會傷腦,研究人員表示,高勞力工作往往伴隨著日復一日的機械性重複、較低的工作自主權與環境壓力,這些因素在無形中削弱了大腦的認知儲備,也因此可能和較高的失智風險有關。

工作勞動無法取代運動3原因

工作勞動為何難取代運動?簡詩敏整理出以下3項可能原因,包括:

●缺乏結構化恢復:運動是練完就收操休息,勞動是長達8小時的低強度慢性磨損,肌肉與血管整天處於微發炎狀態。

●心血管持續承受靜態負擔:長時間站立、負重或用力憋氣,會使血壓長時間偏高,心臟無法獲得間歇性的彈性放鬆。

●失去掌控的心理壓力:在健身房累了隨時能停,但在職場節奏全由主管、客人與產線決定,壓力荷爾蒙會直接抵銷活動的好處。

工作走萬步、久站≠真正運動

簡詩敏也指出,日走萬步、久站都是兩大迷思,因為工作中神經緊繃踩出的一萬步,跟在公園放鬆走走的一萬步,自律神經與大腦接收到的生理訊號完全不同。此外,研究發現,每天站立超過2小時,不但沒有心血管保護效果,下肢靜脈曲張與栓塞的風險反而明顯上升,因此久站並不等於健康。

5大工作族群補足運動這樣做

簡詩敏說,對於不同工作族群,可掌握以下重點,補足日常運動:

●辦公室久坐族:每小時起身活動、中斷久坐,訓練可著重核心及身體後側肌群。

●高步數動態族:如醫護、外場服務業,日常步數已達標,額外運動可換成低壓力的放鬆散步或游泳,並安排阻力訓練保護關節。

●長時間久站族:如櫃哥櫃姐、廚師等,可加強下肢循環伸展,並鍛鍊臀部與核心,減少腰椎代償負擔。

●重度勞力族:如工地、搬運與物流工作者,切忌盲目加碼高強度有氧,高品質的睡眠修復才是第一優先,訓練應以特定受損關節的伸展矯正為主。

●家務與重複勞動族:如清潔人員、主婦,家務多半是特定小肌群的慢性負擔,需要透過全身性大肌群的規律訓練,平衡長年的勞動失衡。

簡詩敏強調,相關研究並非要否定任何人的勞動價值,而是提醒所有在工作與家務中精疲力竭的人,日常生活也須注意好休息的重要性。

Hong Kong launches a unified cigarette box packaging design: the outer packaging texture is banned and the dark brown color is updated. 12 health warning images are updated.

The Tobacco and Alcohol Control Office of the Department of Health of the Hong Kong Special Administrative Region Government announced the latest progress in unifying the packaging design of traditional smoking products. It stipulates that the outer packaging must not have texture, use dark brown uniformly, delete the tar nicotine logo, and update 12 health warning images. The relevant legislation will be gazetted on September 11, take effect on March 1, 2027, and be fully implemented on December 1, 2027. It aims to weaken the brand effect and attractiveness of tobacco packaging and prevent young people from trying smoking.

Nutritionists point out that to reduce triglycerides, we need to pay attention to four major dietary blind spots. Just cutting out oil is not enough.

Nutritionist Zeng Jianming emphasized that high triglycerides do not necessarily come from excessive fat intake. Sugar, refined starch, alcohol heat and excess total calories can also cause the liver to synthesize triglycerides. He listed four common dietary blind spots: excessive refined starch, excessive fruit intake, occasional heavy drinking, and normal weight but fatty liver or insulin resistance. He recommended adjustments in four directions: controlling sugar and starch, limiting alcohol, adjusting starch quality and quantity, and combining weight loss exercises.

Taiwan expands publicly funded nine-valent HPV vaccine vaccination to all junior high school students, ranking first in East Asia for both men and women

Since September 2014, Taiwan has expanded the scope of the publicly funded nine-valent HPV vaccine to all junior high school students, both men and women, becoming the first country in East Asia to provide boys with a complete two-dose vaccine. In the first year, approximately 213,000 junior high school students benefited, with the first-dose vaccination rate reaching 81.6% for boys and 91.9% for girls. Information from the Ministry of Health and Welfare shows that HPV can cause a variety of cancers. Experts emphasize that the vaccine can prevent more than 90% of cancers related to highly carcinogenic types. They also call on parents to sign the consent form as arranged by the school, do not fast before vaccination, and observe for 15 minutes after vaccination.
