1、先学后睡：学习前的小睡可能会加速你的遗忘，这是最新的研究成果，称之为“前睡效应”。研究发现30分钟和1.2小时的前睡都较显著地损害了 记忆，但如果在醒来后待2小时或4小时再学习，记忆就不再受前睡的影响。而且，6小时的前睡比4小时和少于4小时的前睡导致的遗忘要少。这种“前睡效应” 是由于较高的促生长激素水平对人的记忆不利，可使记忆严重受损的结果。而人在入睡后30分钟之内促生长激素迅速释放，并持续一段时间，直至醒后才逐渐地恢复正常。这就是短睡后记忆不好，而清醒一段时间后记忆灵敏的奥秘所在。 先学后食：英国科学家研究表明，饭后人体的消化器官中能分泌出几种激素，其中一种叫缩胆囊肽激素可以增强记忆。试验

2、表明，如在学习之后注射缩胆囊肽激素，与吃饭的效果是一样的。因为缩胆囊肤激素能增强迷走神经的活性，提高大脑的记忆能力。 控制饮水：科学家们最近指出，人体下丘脑合成的抗利尿激素具有增强记忆的作用，而饮水量的多少可调节抗利尿激素的分泌量，间接地影响记忆力。当人们大最饮 水时，血中的水分增多，渗透性下降，血容量增大，人体下丘脑的渗透压感受器兴奋性下降，容量感受器的兴奋性增强，两者都会使下丘脑合成的抗利尿激素减少， 从而不利于大脑的记忆活动。反之当饮水减少、血浆渗透压提高时，抗利尿激素大量分泌，作用于大脑边缘系统，可以增强其记忆功能。所以，适当控制饮水量，对 增强记忆力是有益的。 一词多意/一词多译1.
