一夜无梦”才是高质量睡眠？

有的人认为做梦意味着大脑没休息好，觉得“一夜无梦”才是高质量睡眠。北京大学第六医院主任医师孙伟指出，这是常见的误解。做梦是正常的生理现象，在整夜睡眠中大多数人会做多个梦，但并不是所有的梦都会被记住。做梦是大脑在睡眠中处理重要信息的标志，一般不会损害我们的睡眠质量，而真正损害睡眠质量的是频繁的噩梦。

深度睡眠时间越长越好？

众所周知，深度睡眠阶段是睡眠周期中至关重要的部分，它对身体的修复和大脑的功能恢复起着关键作用。当前，一些智能手表或者睡眠手环会给出睡眠评估报告，很多人会因为这个报告中深度睡眠时间不长感到焦虑。孙伟表示，如果晚上睡眠时间是6~7小时，整夜深睡眠达到50分钟就是正常的。而且随着年龄的增加，深睡眠的比例会逐渐减少，这是一个正常的生理变化，不用担心。

对于用智能设备检测睡眠是否准确，孙伟指出，家用智能穿戴设备是通过心率、身体活动等指标来推断睡眠的分期，和临床上使用的标准多导睡眠监测设备相比还有一定差距，测得的数据也不能直接作为诊断依据。
