熬夜的危害

　　熬夜的危害
　　The dangers of staying up late
　　在最近几天，小编因为控制不住自己想玩手机的念头常常熬夜到深夜一两点，就在今天深夜小编突然感到胸口发闷，头晕甚至有点恶心，小编吓坏了，立刻放下了手机开始睡觉。今天早上起来小编的头仍然很疼，深刻体会到了熬夜带来的伤害。
　　通过查找资料小编了解到，睡眠是人类不可缺少的一种生理现象。人的一生中，睡眠占了近1/3的时间，它的质量好坏与人体健康与否有密切关系。但是在日常生活中，我们经常不自觉地压缩我们的睡眠时间，希望自己能够更好地掌控和利用属于自己的时间。
　　但是我们却忽视了熬夜的危害，首先熬夜会让你的大脑得不到充足的休息时间，人的睡眠分为深度睡眠和浅度睡眠，通常是由浅度睡眠过度到深度睡眠再过度到浅度睡眠，在睡眠时间充分的情况下，一般会进行三到五次的转换。深度睡眠又叫非快速眼动睡眠，它只有达到一小时二十四分钟，才可以基本满足我们的人体需求，在这个时候意识活动较少，大脑处于相对静止的状态；浅度睡眠又叫快速眼动睡眠，它只有达到五小时十五分钟才能保证我们的身体得到完全的放松，在这个时候虽然大脑处于相对静止的状态，但是仍然能够收到外界的信息，苏醒过来。总之，我们需要保持将近七个小时的睡眠时间。
　　其次，长期熬夜会导致用眼过度，影响视力导致视力下降，在严重的情况下会导致白内障，失明等相关症状，同时这些症状也是不可逆的，并不会是你后续补觉可以补上的。我们有时有这样的一个想法，就是今天的觉没睡够中午补一觉或者是明天多睡一会，表面上我们感觉精神得到了恢复，似乎不会对我们产生太大的影响，其实熬夜的危害仍在损伤着我们的身体。
　　最后，熬夜会导致身体的免疫功能下降，引起多种疾病，同时熬夜会让多个器官得不到充分的休息，最后引起心脏供血不足，从而引起猝死。
　　从医学来说，十一点以后睡觉就算熬夜了，但是无法否认我们很多时候都觉得十一点也不是很晚。睡眠的最佳时间段就是十二点到两点，如果十一点无法入睡将会影响深度睡眠，无法保证睡眠的充足。克制自己熬夜的坏习惯吧，养成早睡早起的习惯，宁愿早睡一点去抓住早上的时间，也不要睡得太晚去争夺睡眠的时间。
　　In the last few days, I often stayed up until one or two in the middle of the night because I couldn’t control the idea of playing with a mobile phone. I suddenly felt chest tightness, dizziness and even a little nausea late at night. I was frightened and put it down immediately. I started to sleep with my phone. When I got up this morning, the editor still had a very painful head, and I deeply felt the damage caused by staying up late.
　　Through searching for information, I learned that sleep is an indispensable physiological phenomenon for human beings. In a person＂s life, sleep accounts for nearly 1/3 of the time, and its quality is closely related to human health. But in daily life, we often unconsciously compress our sleep time, hoping that we can better control and use our own time.
　　But we ignore the hazards of staying up late. First of all, staying up late will make your brain not get enough rest time. Human sleep is pided into deep sleep and light reading sleep, usually from light sleep to deep sleep and then to light sleep. Sleep, in the case of sufficient sleep time, usually three to five conversions. Deep sleep is also called non-rapid eye movement sleep. It only reaches one hour and twenty-four minutes before it can basically meet the needs of our human body. At this time, there is less conscious activity and the brain is in a relatively static state; light sleep is also called rapid Eye movement sleep, it only reaches five hours and fifteen minutes to ensure that our body is completely relaxed. At this time, although the brain is in a relatively static state, it can still receive information from the outside world and wake up. In short, we need to maintain nearly seven hours of sleep.
　　Secondly, staying up late for a long time will lead to excessive eye use, affect vision and cause vision loss. In severe cases, it will cause cataracts, blindness and other related symptoms. At the same time, these symptoms are also irreversible and will not be able to make up for your subsequent replenishment. We sometimes have the idea that if we don’t sleep enough today to make up for noon or sleep for a while tomorrow, on the surface we feel that our spirits have been restored, and it doesn’t seem to have much impact on us. In fact, we stayed up late. The harm is still damaging our bodies.
　　Finally, staying up late will lead to a decline in the body’s immune function and cause a variety of diseases. At the same time staying up late will make multiple organs not adequately rested, and finally cause insufficient blood supply to the heart, leading to sudden death.
　　Medically speaking, if you go to bed after eleven o＂clock, you are staying up late, but we cannot deny that we often feel that eleven o＂clock is not too late. The best time to sleep is from 12 o＂clock to 2 o＂clock. If you cannot fall asleep at 11 o＂clock, deep sleep will be affected and sufficient sleep cannot be guaranteed. Restrain your bad habit of staying up late, and develop the habit of going to bed early and getting up early. I would rather go to bed early to seize the morning time than sleep too late to compete for sleep time.
