健康睡眠金标准:6~8小时


����  刚好 最近选床垫     发现的

摘要: 好不容易等到个周末,一觉睡到自然醒,这是很多现代压力山大女性的休息方式。但是小编提醒你,睡太多没太多好处,而且还要当心越睡越傻。一起来看看睡觉太多反而危害健康的原因是什么吧。

 

三、睡眠

 

美国的研究人员在对9万多名50~79岁的女性进行了长达7年半的调查后发现,每天睡眠超过9小时的人中风危险比睡7小时的人要增加70%,睡眠时间是增大中风危险的独立因素。南京脑科医院的专家介绍,老年人的血液黏稠度比较高,如果睡眠时间过长,就会导致血液黏稠度增加,而血液黏稠度增加就容易诱发中风等脑血管疾病。

 

四、睡眠中枢太亢奋反应迟钝脑发昏

 

“一晚睡10个小时,为什么白天还是无精打采呢?”很多人都有这种“越睡越困”的感觉。想用增加睡眠时间来获得健康的观念,是完全错误的。睡眠时间过长的人,就会变得懒惰、软弱无力,甚至智力也会随之下降。

 

经常睡懒觉的人,因肌肉组织错过了活动良机,起床后会感到腿软,周身无力。而且,睡懒觉会使人的睡眠中枢长期处于亢奋状态,而其他神经中枢受到抑制,恢复活动的功能就会变得相对缓慢,因而会感到终日昏昏沉沉,甚至智力下降。

 

五、健康睡眠金标准:6~8小时

 

那么,究竟每天要睡多久才有利于健康呢?专家认为,对于成年人来说,6~8小时是其所需的标准睡眠时间,老年人在这个标准上再减少1~2个小时,青少年可以增加1~2个小时。对于婴幼儿来说,睡眠时间则需要更长。

 

以上是关于睡觉对健康影响的内容介绍,平时都说要保证充足的睡眠,不代表因为劳累就睡到自然醒,6-8小时的睡眠是好的,但是早上不吃早餐确是不好的习惯。更多关于日常保健的内
