Staying up late will be detrimental to human health, because the adrenal cortex hormone and growth hormone are all secreted during the night when people are sleeping. The former is secreted before dawn, which can promote the metabolism of carbohydrate in human body, and protect the development of muscle; while the latter is produced only after sleep, which can not only promote the growth and development of young people, but also can delay the aging process of the elderly. As a result, staying up late will cause a variety of harms to human body.
First, frequent fatigue and decreased immunity
The most serious sequence caused by staying up late is fatigue and lack of energy. What's more, the immunity of human body will decrease accordingly. And some other symptoms such as cold, gastrointestinal infections, allergies will also appear.

关于熬夜的英语作文 当午夜多数人已经进入梦乡时，“夜猫子”们的生活才刚刚开始。
很多人坚信自己夜间才能精神抖擞，才能高效率工作，但医生们却说这样有损健康，熬夜还是不熬夜？这是一个问题。 1. You may need more sleep than you think. Research by Henry Ford Hospital Sleep Disorders Center found that people who slept eight hours and then claimed they were "well rested" actually performed better and were more alert if they slept another two hours. That figures. Until the invention of the lightbulb , the average person slumbered 10 hours a night. 1、你需要的睡眠时间也许比你想象的要久。
“亨利？福特医院睡眠疾病研究中心”的研究表明，那些在8小时睡眠后声称自己“休息得很好”的人，如果再让他们睡两个小时，实际上会表现得更好而且更加有精神。这一点貌似是有考试~大道理的。
在电灯发明以前（该死的爱迪生），人们每晚的平均睡眠时间通常是10小时。 2. Night owls are more creative. Artists, writers, and coders typically fire on all cylinders by crashing near dawn and awakening at the crack of noon. In one study, "evening people" almost universally slam-dunked a standardized creativity test. Their early-bird brethren struggled for passing scores. 2、夜猫子更富创造力。
艺术家、作家和编程人员是典型的“日落而作，日出而息”。他们在夜间精神抖擞，眼放精光，而不到日上三竿不会起来。
在一项研究中，夜猫子几乎都很轻松地高分通过了标准化创造能力测试，而那些信奉“早起的鸟儿有食吃”的老兄们则在及格线上挣扎。 3. Rising early is stressful. The stress hormone cortisol peaks in your blood around 7 am. So if you get up then, you may experience tension. Grab some extra Zs! You'll wake up feeling less like Bert, more like Ernie. 3. 早起让你倍感压力。
早上7点左右你血液中的压力荷尔蒙皮质醇含量达到最高。所以如果在那时起来，你会感到心绪紧张。
再倒头睡个回笼觉吧！这样你起来的时候将更像一个孙悟空，而不是猪八戒。（注：原文中的Bert和Ernie是美国着名的幼儿教育电视节目。
Get Up Early or stay up late
Many people want to ask, what is the best time for sleep? Do we need to sleep early or late? My opinion is to sleep early. Here is the reason why we should sleep early. First, it will make you more healthy. Sleep late would cause illness, long time not sleeping early will damage your body. Second, many people had said that if you don't get many time to sleep, and you sleep late would make black rim of the eye. That is not healthy also, and it's not beautiful. We should give our body a rest. Sleep is the best way. Well, there are certain time that is best for us to sleep. Sleep early is definitely better than sleep late. Also, we should not keep awake the whole night. You don't feel the damage when you are young, but when you get older, the problem start to appear. Many disease of heart and lung started from not sleep at night. Many youth think it is fun to keep awake or sleep late. But I don't think so. Keep your body healthy. I strongly suggest to sleep early.
The obvious advantage of burning the midnight oil is that you're able to hand your assignment/homework to your teacher the next day. Doing homework at the unholy hour affords you the silence to finish them. However, it doesn't guarantee the quality of the work done since tiredness could be a factor. Furthermore, there's always the possibility of falling asleep in the class the next day.。

Nowadays,with the rapid development of IT and information industry, cell phones play a dominant role in towns people's life. But, like everything else, they have both favorable and mffavorahle aspects.
First, it's useful. As a wireless mobile telephone, it's easy and handy to early to wherever one goes and call the callee however far away he is. Therefore, it greatly facilitates people's life. Second, it's convenient. Whenever one meets trouble or something urgent, one can nmke a call immediately. Most important of all, it's a very helpful companion. With a multirfunction cell phone in hand, one can easily get on the Net, browsing the useful information, conducting e-commerce and doing whatever one can do via Internet.
However, just as everything has two sides, the cell phone also has many disadvantages. To begin with, it's expensive to buy and costly to pay the hills, esp. that of global service. To make matters worse, it's also easy to lose and costly to get it repaired. Worst of all,it's not as clear as a family telephone and sometimes the number dialed is often not available. Last but not least, it's alleged the microwaves in it might do harm to people's health.
In my opinion,with its expenses greatly reduced after China's entry into the WTO, it will face an ever brighter future in its development. Someday most of them will be developed into new Intemet-enabled mobile phones, which will be as useful as pocket comp uters. And I believe its advantages will not only offset its disadvantages, but also far outweigh them.
Since the introduction of mobile phones, concerns have been raised about the potential health impacts from cellular phone use. Studies from the National Cancer Institute and researchers at the Danish Institute of Cancer Epidemiology in Copenhagen do not show any link between cellular phone use and cancer. The Danish study only covered analog mobile phone usage up through 1995, and subjects who started mobile phone usage after 1995 were counted as non-users in the study.[16] However, a study by the International Agency for Research on Cancer of 4,500 users found a statistically significant link between tumor frequency and mobile phone use。
嘿嘿，自己写的，不够好不要怪我啊~~ 不过绝对原创啊~~ It is very obvious that people living in the highly developed modernized society can't imagine the life without mobile phone. It is also well admitted that the adoption of moblie phone does a lot good to people in interpersonal or social communication. But there are some peoblems or disadvantages often ignored by those who take mobile phone as something precious as life. Here are the problems. First of all, no matter how good or advanced the mobile phone technique has grown, the users still can't get rid of the radiation of the personal phones. The radiation still does sometimes a little damage to the human body. The damage is so small that people mostly don't take notice of it. But when the small amount of damage accumulates, cancer will be the bad consequence of the radiation. There are already many example of this kind. When the people are awaken, it is always too late. As students, we also have to know that the frequent use of mobile phone will affect out study. Mobile phone provides huge convenience to communication so we may easily get in touch with others. As a result, the time and the consentration on study will be detracted. The less time we spend on study, the worse our grades will be. Even if nowadays many mobile phones have got the function of play all kinds of games, more and more students play the games sometimes in class to "kill time". This does no good to our study at all. Last but not least, the most important thing that we forgot is that the money we put into the mobile phone. We should know that the phones are already very expensive themselves. But every month the money we spend on them may be even more. We are the students who haven't got a job to supply our living. So how can we earn the extra money to pay off the bills? From these points, I didn't mean that we should not use mobile phone. It is just a reminding for those who live on mobile phones that they are not so good and they have a lot of disadvantages we should be aware of.。
As the mobile phone is more and more widely used in classroom,even on campus began to play popular mobile phone.With the mobile phone function is more and more intelligent,games,chat has become many student entertainment project,slowly,mobile phone start encroached on students learning time.At the same time,mobile phone also provides great convenience for our lives,interest relatives and friends very fast,very convenient.But in school we should put an end to the mobile phone.In class on mobile phone related class,in the class rules added to mobile phone use in the classroom,make students feel a heartfelt admiration and acceptance,the parents' meeting to inform parents of this provision,the parents cooperate with.
students may get distracted if they go to school with a smart phone. Short mail, games and lots of apps are more abstractive than some boring lessons. Besides, if students is using to search answers by telephone instead to finding solution through listening classes, they may get bad study habit.
Nowadays mobile phones are becoming more and more popular among the middle school students. In my opinion, we can bring mobile phones to school.
As we know, the 21st century is a modern age and full of information. A mobile phone is one of the quickest tools for us to exchange information. The mobile phone is a fashionable and useful invention, so we ought to make the best use of it. Suppose there's a sudden accident, it is more convenient for us to dial for help immediately. There're also some games in the mobile phone. We can relax ourselves by playing them when we're tired of our studies.
In my opinion, it's not wrong to follow the fashion, but the most important thing is how to use the mobile phone in a right way.
现如今，越来越多的中学生开始使用手机。我认为，学生在学校应该使用手机。
众所周知，21世纪是一个信息化时代，各种各样的信息满天飞，手机是一种时尚和有用的发明，所以我们应当使用它。假如有什么紧急情况发生，我们可以立即使用手机拨打电话求助。而且手机里也有一些游戏，当我们学习学累了可以玩一下，已达到放松的目的。
我认为，紧跟时代的潮流是没有错的，把手机用到正途上才是关键。

你好，这里琉璃~很高兴为您答题！如果以上答案能帮助你，请采纳本条答案~
本文的内容有：1.手机在学校里使用的普遍性；2.手机的优点；3.在校园里使用手机的危害及我的建议。---- Cell phones have become increasingly popular in China these days. Wherever you go you can see people using cell phones. Many college students, even high school students, have cell phones. Cell phones have brought people a lot of benefits, but the most important is that they are convenient. With cell phones in their hands, they can keep in touch with anybody they want. If they want to get some information from the Internet, they can easily have their dream realized via cell phones too. Furthermore, if someone has a heart attack or a traffic accident, a call to emergency hospital or to the police can quickly bring him the help he wants. However, cell phones can also bring people problems. The most serious is the electric wave radiation which is thought to be harmful to users' brains. Another problem is that when people are having a meeting or having a class or at a concert etc, the ring of the cell phone may interrupt others. So I think people should use cellphones as little as possible and turn them off when they are attending important meetings or attending classes.
