滑手機做2事恐忘東忘西? 營養師:注意力與睡眠是關鍵

營養師張馨方表示,研究指出,使用手機若經常做2件事,可能與影響注意力、學習與記憶表現相關。

Quick Look

營養師張馨方指出,頻繁滑短影音、切換通知及睡前滑手機壓縮睡眠,可能與注意力、學習與記憶表現變差有關。不過研究顯示的是關聯而非因果,建議養成用餐放下手機、關閉通知與睡前無手機時間等習慣。

Why It Matters

忘東忘西不一定只是年紀大,也可能和每天使用手機的習慣有關。

〔健康頻道/綜合報導〕忘東忘西不一定只是年紀大,也可能和每天使用手機的習慣關。營養師張馨方表示,手機本身不會直接讓人變笨,研究指出,若長時間滑短影音、頻繁切換訊息與通知,注意力不斷被打斷,加上睡前滑手機壓縮睡眠,都可能影響注意力、學習與記憶表現。不過,她提醒,這類研究主要呈現的是關聯,並非因果關係,因此,目前仍不能證明認知與表現差是手機直接造成。

頻繁切換任務 注意力容易被打斷

張馨方於臉書粉專發文表示,滑短影音、看訊息、回通知,再切回原本正在做的事情,大腦並非真正同時處理多項任務,而是不同任務之間快速切換。研究發現,較頻繁的媒體多工使用,與較差的注意力及學習表現有關。美國兒科學會(AAP)也曾提醒,同時使用多種媒體可能影響專注,學習時可能需要花更多時間與反覆練習,才能吸收資訊。

研究:短影音使用與認知表現有關

張馨方說明,可將大腦想像成一台相機,注意力等於對焦功能,如果訊息一直跳出、一直滑下一個影片,大腦連對焦都不完整,資訊自然比較難被記住。她表示,2025年發表於《Psychological Bulletin》的系統性回顧與統合分析,共納入71項研究、9萬8299人,結果發現,較高的短影音使用程度,與較差的整體認知表現有關,其中與注意力及抑制控制的關聯較明顯。

不過,張馨方提醒,這類研究主要呈現的是關聯,不是因果關係,所以目前不能直接說「滑短影音一定會造成記憶力下降」。比較精確的說法是,長時間、高頻率的短影音使用,可能與部分認知功能表現較差有關,但目前還不能證明是手機直接造成的。

睡眠不足恐會影響記憶、學習

她並提及,另一個容易被忽略的因素是睡眠。若睡前總是滑手機一支影片接一支看,不知不覺越滑越晚,問題可能就不只是手機。美國國家衛生研究院(NIH)指出,睡眠有助於學習與記憶,睡眠不足則可能影響注意力、學習及記憶表現。換句話說,可能不是「手機把記憶力吃掉」,而是注意力一直被打斷、睡眠時間被壓縮,導致隔天更容易覺得腦袋卡卡、忘東忘西。

張馨方強調,並非需要完全戒手機,而是應該避免讓大腦長時間處在快速刺激、切換,再快速刺激的模式。建議可先從吃飯時先放下手機、工作或讀書時關閉不必要的通知、睡前留一段「無手機時間」等3習慣著手,讓大腦有機會專心處理單一事情,也保留足夠睡眠時間。

  • 短影音與認知表現差之間的具體因果機制為何?

Doctor reminds: Restructured meat must be fully cooked to be safe, otherwise it may easily cause gastroenteritis

Zhang Canxuan, an attending physician at the Gastroenterology and Hepatobiliary Department of Shin Kong Hospital, pointed out that the processing of recombinant meat brings surface bacteria into the interior. If it is not thoroughly heated until fully cooked, it is easy to ingest pathogenic bacteria and cause acute gastroenteritis. The risk is especially higher for the elderly and young children. It is recommended that when eating out, make sure the center of the meat is fully cooked.
