用英语写一篇关于不午休的危害的文章

午休对缓解疲劳有很大帮助。但午休不是简单的倒头就睡，错误的午休习惯会危害身体健康，下面给大家介绍几种健康的午休方法：1、少吃油腻食物，不吃得太饱。油腻食物会增加血液黏稠度，此时睡觉易形成冠状动脉病变；吃得太饱会增加胃肠负担，影响午休质量。2、午休姿势宜仰卧或侧卧。不要坐着或趴着打盹，这样会减少头部供血，使人醒后出现头昏、眼花、耳鸣等症状，时间长了还易引发脊柱变形、腰肌劳损。3、午休不宜长。午休以半个小时为宜，如夜晚睡眠不足或上午过度劳累可适当延长。因为睡眠时间过长会进入深睡眠状态，醒来后反而会头昏体乏。4、午休后起床勿太急。午睡后要慢慢站起，再喝一杯水，以稀释血液；不要马上从事复杂和危险的工作。5、午休要避免着凉。午休时身体抵抗力比较弱，不要随便在走廊上、树荫下、草地里午休，防止地面寒气入侵。要避免空调、风扇直吹人体，避免受风寒。许多人都有午餐后疲倦的烦恼。英国学者就这一现象进行研究，发现每日午后小睡10分钟就可以消除困乏，其效果比夜间多睡两个小时好得多。据日前出版的德国《星期日图片报》报道，在德国越来越多的上班族有了午间在办公室休息的习惯。

午睡不仅能提高工作效率还能预防冠心病。据医学家研究观察，每天午睡30分钟，可使体内激素分泌更趋平衡，使冠心病发病率减少30%。研究者认为地中海各国冠心病发病率较低与午睡习惯是分不开的。而北欧、北美国家冠心病发病率高，其原因之一就是缺乏午睡。成人睡眠不足4小时者，其死亡率比每晚睡7至8小时的人高180%。这就提示人们，晚间睡眠不足，如能在午睡中适当补充，也将有益于延年益寿。

需不需要午睡和个人自身的体质、睡眠状态、年龄和有无疾病等条件密切相关。凡是平素睡眠不足的人及体弱多病的人都该午睡；对从事脑力劳动的人和中小学生而言，午睡更值得提倡。睡眠质量差的老人也能通过午睡让大脑得到真正的休息。
