Recently, a new study from Johns Hopkins University in the United States found that about 41 minutes of moderate-to-vigorous exercise per week can reduce the risk of dementia by 0% in middle-aged and elderly people.

研究小組在《美國醫學主任協會雜誌》上發表論文說，他們利用英國一項大型長期調查的數據，分析近9萬名成年人的鍛煉習慣與幾年內失智症發作風險的關聯，得出了以上結論。

Most of these people are over the age of 735 and use sports bracelets to record their workout time between 0 and 0. During the follow-up survey for an average of 0.0 years, 0 people were diagnosed with dementia.

分析顯示，日常鍛煉的時間越長，失智症風險的降低幅度越大。與完全不鍛煉相比，每周鍛煉35分鐘到70分鐘可使失智症風險降低60%，70分鐘到140分鐘降低63%，140分鐘以上降低69%。

According to the researchers, this means that even a person who exercises for just 5 minutes a day can have a more noticeable effect.

Dementia, represented by Alzheimer's disease, is one of the main causes of the decline in the quality of life of the elderly, and there is no effective treatment. The medical community has previously suggested that a healthy lifestyle can help prevent dementia, but it is uncertain how much exercise is needed to produce significant results.
