hibernation is more than sleep. it is a very deep sleep.the animals temperature drops to just over zero centigrade,and its heart beats very slowly. people who find hibernating animals asleep often think that they are dead: the body feels very cold, and the creature may breathe only once every five minutes. a hibernating animal cannot feel any pain. you can touch it, or even pull its tail, without causing it to move or wake up. in its hibernating state it can even live in a poisonous atmosphere for a long time without any ill effect.

hibernating in this way, the animal can sleep all through the winter. you might wonder how it manages to live without eating for so many months. the answer lies in two facts. thefirst is that it has stored supplies of fat in its body during the summer and autumn. the second is connected with the main use the body makes of food -- to supply the energy for movement. we have seen that hibernating animal reduces movement to far below the ordinary level. even the movements of the heart and lungs are greatly reduced. the animal hardly makes any movement, hardly use any energy, and hardly needs any food.

some animals, including some bears only half hibernate.that is to say, they sleep during the winter, but their sleep is not deep and their body temperature does not drop, as they are warm-blooded animals. in the antumn the bear eats and eats and becomes very fat. his hair grows longer. soon he has a thick covering of fat and fur. in november he finds a place to lie down and goes to sleep. on warm winter days he may think spring has arrived; he gets up and walks around. when he sees that the snow is still thick on the ground, he quickly goes to sleep again.

大家好！

现代人的生活节奏在逐步的加快，人们的目标也都相对明确，奋斗的故事数不胜数。朝着目标努力的过程中，总少不了加班熬夜，甚至通宵达旦，消耗了我们不少的精力。慢慢地，就养成了习惯，晚睡早起，就算有时间的时候也会找点事情消耗时间到很晚才睡觉。然后，我们会发现，人群中有不少这种晚睡早起的人，他们有个共同的特点就是易燥易怒，身体状态也每况日下。

睡眠是解决烦恼的法宝。烦躁的心情下很难给自己一个认真思考的机会，遇到阻力就大发雷霆，指责朋友，埋怨员工。头脑整日里处于高速运作的状态，很难放松下来。紧绷着的精神如不断冲水的水库，容量有限，总有一天会因为无法承受这么大的容量而决堤崩溃。我们的精神状态也是如此，长期的消耗精力，不做补充，或则补充的能力无法弥补消耗的部分，也会处于不平衡状态，精神不振。所以，大家要强制性给自己一个适度休息的机会，找个时间好好睡个觉，缓解下平时工作的高度压力，给身心一个充电的机会。这样你将获得平静的心态。

睡眠是身体健康的良药。烦躁的状态属于不健康的状态，身体的健康从表相上可以窥得一二。当你感冒的时候，必定是两眼无神，面无表情。当你肚子痛的时候，必定是面色狰狞，精神涣散。当你头痛的时候，必定是双目紧闭，眉头紧锁，无精打采。种。种的健康状况都可以从表相来窥探，而身体健康的维持是现代人的一大难题。睡眠，间接的影响着人们的健康，晚上不休息会影响身体的排毒。睡眠不足，还会影响心脏的造血功能，导致各类血液疾病的发生。睡眠不足，还会导致头痛等病发证的发生。众多的医学临床表明，睡眠与人类的身体健康有着密切的关联，我们不得不重视睡眠在我们生命中的重要性。

睡眠是提高记忆的补品。儿时的我们，记忆力超强，死记硬背的功夫展示得淋漓尽致。而随着年龄的增长，我们的所接触的事物在不断的增多，需要记忆的东西也非常多，然而会发现记忆力在逐渐衰退。年迈的老人中我们不然发现，记忆力下降成为非常显著的特点。而从老年人的习惯中我们还会发现，老人的睡眠已经无法保证长时间睡眠了，一般老人会养成早睡早起的习惯。从少年和老年的两种表现中，我们不然发现，年龄的增长，睡眠时间在不断减少，记忆力在不断衰退。因此，增加睡眠时间和睡眠质量，对我们记忆力的提升有着莫大的帮助。

睡眠，给我们一个清醒的头脑；

睡眠，给我们一个快乐的心情；

睡眠，给我们一个瓶颈的心态；

睡眠，给我们一个健康的身体；

睡眠，给我们一个良好的记忆；

睡眠，给我们一个美丽的面容；

睡眠，我我们一个幸福的生活；

睡眠，给我们一个精彩的世界！
