Train Your Brain

Is there anything you can do to have a better memory？ Research shows that mental and physical exercise and lifestyle choices can affect memory. In fact， many experts agree it is possible to improve your memory.

Here are some tips：

Avoid stress

Recent research shows that stress is bad for the brain. In fact， one study reveals that there is a close connection between worrying and memory loss. Therefore， if you can avoid stress in your life， you may also improve your memory. Relaxation techniques like yoga are one way to reduce stress.

Play games

Can brainteasers like sudoku （數(shù)獨） puzzles improve memory？ Some scientists say that mental activity might help memory. Puzzles， math problems， even reading and writing， can probably all benefit the brain.

Get some rest

“Poor sleep before or after learning makes it hard to encode （把……編碼） new memories，” says Harvard University scientist Robert Stickgold. One study shows that by getting a good night's sleep， people remember a motor skill （such as piano playing） 30 percent better.

Eat right

Your brain can benefit from a healthy diet， just like the rest of your body. Foods that have antioxidants （抗氧化物質(zhì)）， such as blueberries， are good for brain cells. This helps memory.
