Practical tips on improving your memory

有效提高你的記憶

Have a healthy iron level.

維持身體里鐵含量的正常水平

Iron deficiency can have adverse effects on brain function, including attention and memory issues.

缺鐵會影響大腦功能，包括注意力和記憶力的問題。

Studies have shown that people who have low iron levels and took memory tests took longer to finish these tests, as well as scored significantly lower than people with normal iron levels.

研究表明鐵元素含量低的人、參加記憶力測試所需時間長的人，他們體內鐵元素的含量明顯低于正常人。

Thankfully, taking an iron supplement easily reverses these negative points.

值得慶幸的是，補充鐵很容易改善這一點。

In that same study, people who took supplements scored at a normal level just a couple of months later.

研究也表明補充鐵以后，幾個月內就能恢復正常水平。
