研究显示,睡眠越充足的孩子,其大脑中与记忆和感情有关的海马区的体积越大,大脑发育得越好。海马区是大脑学习和记忆的关键区域。日本科学家对290名5~18岁的未成年人的睡眠时间和海马区体积进行了调查。结果发现,与只睡6小时的孩子相比,每天睡眠达10小时以上的孩子海马区的体积要大10%左右。研究人员指出,如果 Studies show that children who sleep more adequately, the larger the volume of the hippocampus associated with memory and affection in their brains, the better the brain develops. The hippocampus is a key area for brain learning and memory. Japanese scientists investigated the sleep time and the hippocampal volume of 290 minors 5 to 18 years of age. The results showed that, compared with children who slept only for 6 hours, the volume of hippocampus in children who sleep more than 10 hours per day is about 10% larger. The researchers pointed out that if
