很多人有睡午觉的习惯，但在这些人中，有一部分人却因睡姿不当、睡眠时间失度而使午睡质量大打折扣。有四个午睡禁忌让你越睡越难受
据专家介绍，睡午觉不能太随便，科学、有效的午睡是健康充电的好方法，千万不要把午睡变成“误睡”，这里面就要注意四个要点和四个禁忌。
四个午睡要点：
1、睡前不吃油腻食物，不吃得太饱。油腻食物会增加血黏稠度，加重冠状动脉病变，加重胃消化负担。
2、午餐后不宜立即躺下午睡。午餐后大量的血液流向胃，血压下降，大脑供氧及营养明显下降，易引起大脑供血不足。一般应食后休息十几分钟再午睡。
3、睡姿应取头高脚低、右侧卧位。这样可以减少心脏压力，防止打鼾。
4、醒后轻度活动。午睡后要慢慢站起，再喝一杯水，以补充血容量，稀释血液黏稠度。不要马上从事复杂和危险的工作，因初醒时常使人产生恍惚感。

三》》忌坐着或趴着打盹
坐位及伏案睡觉会减少头部供血，使人醒后出现头昏、眼花、乏力等一系列大脑缺血缺氧的症状。有的人用手当枕头，伏在桌上午休，这样会使眼球受压，久而久之易诱发眼疾。
四》》忌人人都需要午睡

Many people have the habit of napping, but some of these people have improper sleeping position, or don't have enough sleep, which greatly reduced the quality of a nap. There are four napping taboo that will make you feel uncomfortable the more you sleep. According to experts, taking a nap cannot be too casual.

Listed below are 4 important precautions and 4 taboos that you'll need to beware of before taking a nap:-

1. Before going to bed, do not eat greasy food and avoid eating too much. Greasy food will increase your blood viscosity and the coronary artery lesions, whilst overeating will increase the burden of the stomach.
2. One should not lie down immediately after lunch, not to mention napping. After lunch, a lot of blood will flow to the stomach, decreasing your blood pressure and also the oxygen supply and nutrients to the brain, which could easily cause brain insufficiency. So one should rest for about ten minutes after eating before taking a nap.

4. Attempt some mild activity after waking up. Slowly stand up after a nap, then drink a glass of water to normalize blood volume and dilute blood viscosity. Do not immediately engage in a complex and intensive activity, this one often engender a sense of trance when partially awakened.
