A NASA-funded study on astronauts found that naps up to two and a half hours long improved working memory performance.

美国国家航空航天局资助的一项针对宇航员的研究发现，长达两个半小时的小憩可以提高工作记忆能力。

The general rule is the healthier the diet, one that is rich in fruits, vegetables, whole grains, beans, and oily fish, the larger the brain's memory center and the better the memory performance.

一般来说，饮食越健康越好，多吃水果、蔬菜、全谷物、豆类和油性鱼类，大脑的记忆中心越大，记忆力越好。
