scroll 0 1 这段时间门诊里咨询睡眠问题的中老年朋友不少，发现一个挺普遍的现象：很多人都知道午睡养人，却很少有人留意午睡的方式对不对。有的一睡就是两三个小时，有的吃完饭往桌上一趴就睡，醒了反而头晕、心慌，晚上还整宿失眠。
今天就跟大家说说，过了50岁午睡要牢记的“四不要”，睡对了才是养身，睡错了反而给身体添负担。很多老人都有个固有想法，中午睡得越久，下午越有精神，还能补上晚上没睡够的觉。

不少人吃完午饭就躺下，一睡就是一下午，觉得睡够了才叫休息到位。 睡时长超过1小时，反而可能升高心血管疾病风险，并非睡得越久越养人。
医学共识认为，人的睡眠分为浅睡眠和深睡眠阶段，一般入睡后20-30分钟以内多处于浅睡眠状态，这个阶段醒来，头脑清醒、身体放松，解乏效果最好。
如果睡超过1小时，就会进入深睡眠周期，这时被叫醒很容易出现“睡眠惰性”，头晕、乏力、反应迟钝，要好半天才能缓过来。
更重要的是，中老年人本身血管弹性下降，长期午睡时间过长，会打乱昼夜睡眠节律，导致夜间睡眠变浅、入睡困难，而长期夜间睡眠紊乱是高血压、血糖波动的明确诱因。临床观察发现，每天午睡超过90分钟的老人，出现代谢综合征的风险会明显升高。

对于绝大多数中老年人，午睡时长控制在20-30分钟是最优选择，最长也不要超过45分钟。如果前一天晚上确实没睡好，中午可以适当延长，但也尽量别超过1小时。
