科學家研究了一種稱為 AQP4 的基因。他們發現睡眠非常重要。攜帶此基因的人如果睡眠不足，腦細胞流失的速度會更快。

Other scientists studied light. They looked at 90,000 people. They found that bright light during the day helps the brain. It lowers the risk of dementia.

其他科學家研究了光線。他們觀察了 90,000 人。他們發現白天的充足光線對腦部有益，能降低患失智症的風險。

Light helps people with a special gene called APOE ε4 the most. It also helps people who like to stay up late at night.

光線對攜帶 APOE ε4 特殊基因的人幫助最大。對於習慣熬夜的人，光線同樣有幫助。
