说服性演讲范文不要熬夜精选5篇思维导图

Do you always work or study until midnight?

Do you often hang out or spend much time in pubs at late night?

If you answered yes to either of these questions, you are unfortunately one of the large groups of people who always stay up late. Because of the fierce competition in the society, it seems that everyone has endless work to do and twenty-four hours per day is not enough. Therefore, an increasing number of people stay up late in order to finish the mountainous work. Besides, lots of young people enjoy entertaining at late night. However, many of them are still not aware of the bad effects of staying up late. In fact, it does severe harm to us in three aspects, namely physical health, work efficiency and mental stress.

In the first place, staying up late badly impacts on our physical health condition. The human adrenal cortex hormone and growth hormone, which are vital substances for human body, only secrete at night. The former secretes before the dawn facilitating the carbohydrate metabolism and protecting the development of muscle function. The latter only secretes after sleeping. It can improve the growth of the young and slow down the aging of the elderly. However, if people often stay up late, the secretion of these two substances will be gravely impacted. Finally, our health condition will be degraded. It can cause a variety of harms to human body. Normally, frequent staying up late will lead to fatigue and degraded immunity. People may easily get sick when the weather gets a little bit colder or hotter. In addition, it can also cause headache. People may feel heavy in the brain and dizzy for a whole day. Besides, the fertility of both male and female will be impacted. For women, it will affect the secretion of female hormones and the quality of ova. It also tends to affect the menstrual cycle. For men, both the quality and quantity of sperm will be impacted. What is more, staying up late can also damage people’s eyesight, skin and memory capacity, and cause black eyes as well.

Furthermore, it negatively impacts on the work efficiency. On the one hand, owing to the discomfort of your health as mentioned above, you may feel distracted from the work. On the other hand, because of the decrease of the memory capacity, your work efficiency will be lower, which means that you may not complete the things as you want. Assume that you are a university student and you plan to review for your psychology examination next week after tomorrow’s class. Nevertheless, you stayed up late yesterday for some reason. Therefore, you probably be late for tomorrow’s class or even skip it. Thus, you must find other time to compensate for it. Afterwards, when preparing your examination, you may feel headache and cannot concentrate on it, thus having difficulty memorizing and understanding the psychological terms and principles. Therefore, your schedule for reviewing chapter 2 and chapter3 will be changed. You can only review chapter 2 and may not finish chapter 3. However, in order to finish reviewing on time, you are more than likely to stay up late again. Then, you will be in the vicious cycle and your work efficiency will be lower and lower.

What is also noticeable is that staying up late can bring about mental stress. Since your work efficiency is lower, you probably doubt yourself whether you are a capable person or not. You may think you are not so smart as others and even fear yourself that you can hardly get a good grade in your psychology examination, which makes you feel more anxious and upset. Besides, if you frequently stay up late, you definitely look tired and in low spirits. Therefore, when working on a group project, maybe nobody wants to be in the same group with you, a low-efficient and anxious person. Thus, you will feel separated from others, which possibly makes you more stressed and upset.

In conclusion, although we have a lot of work to do and various activities to participate in, staying up late is by no means a good choice for us. It badly impacts on our physical health, lowers our work efficiency and makes us stressed and anxious. Faced with too much work, we should make good arrangements in advance and maintain a healthy lifestyle.

尊敬的老师们，亲爱的同学们:

大家好!

我躺在床上，辗转反侧，望着窗外，数着数不完的星星，每一颗星星都那么闪耀，那么迷人，那么独特，无数的星星点缀着这广阔的夜空。

静静的望着明月，月光悄悄的抚摸着我的脸颊，我顿时回忆起了童年。小时候，妈妈常常背着我上学校，一路上欢声笑语，引来不少羡慕的眼光。冬天，妈妈骑着电动车送我上学，每到学校时，我都会看见妈妈的手被寒风吹的又红又肿，像猪蹄一样，我看在眼里痛在心里。

这时，又回想起了我与爸爸的时光。那是我很听话，我和爸爸很合得来，和他之间没有什么代沟，也很少吵架。在每次过生日的时候，老爸都会买一个大大的蛋糕，很多的零食，还会有一份精美的礼物给我，或者带我去游乐园潇洒一回。想想那段美好的时光，我都会觉得很开心，甚至很满足，很谢谢爸爸。

想着想着，我的眼泪就流了下来，想想自己原来是那么的幸福，但有时候却也是孤单、难过的。现在，爸爸妈妈都在为我和弟弟的将来而奋斗，打拼事业。他们都在远方，而我却留在了家乡读住宿学校。不过，我不怪他们，我能理解他们，但我多么希望能出一份力来帮助爸爸妈妈，可是我还没那个能力。每每听到父母在电话里的声音，我心中的苦都消失了，换来了喜悦和开心，他们也很开心。也许会想我而伤心，但他们却都不会表现出来，不让我知道他们现在的生活。其实我都知道，所以我现在会好好努力的学习，将来为爸爸妈妈减少一份负担。

渐渐的，快到子时了，可我依然睡不着，一闭上眼睛，满脑子都是父母的影子。想到这里，我的眼泪就又流出来了。我用被子遮住头，强忍着哭泣声，泪水从鼻梁顺着鼻尖落入嘴巴，咸咸的，冷冷的，心里难受的很。我触摸着枕头，湿了一大片。我想，我这一晚上应该都睡不着了吧。眼泪一直流着不停，心里一直都是冷冷的。

月光越来越暗淡了，一阵风吹来，一块浮云遮住了这明亮的月亮，月亮也该睡觉了。月亮睡着了吧，可是我却还没有睡着，我又熬夜了…
