熬夜的危害作文200字 第一篇

在黄黄的灯光下,一本厚厚的课外书本正放在书桌上,与之同时,我常常坐在椅子上打哈欠。每个人都有熬夜的坏习惯,我就是其中的一个。有时候我们熬夜是因为学习,但学习时的时间一定也是要限度的。但除了学习以外的熬夜,例如玩游戏,看漫画,看电视,玩电脑之类的熬夜,那便是不可取的。我常常喜欢在晚上看课外书,一看就是晚上十一点。

对于这个熬夜的坏习惯,我向来是没有改掉这个熬夜的坏习惯的。那个时候,我看着课外书,看得很精彩,看得很投入,一看就看到了晚上十一点多,当为看下闹钟的时候,发现时间太晚了,便放下课外书休息了。一晚上我睡得特别沉,像是怎么睡都睡不完一样。到了早上,当闹钟的零食响起来的时候,由于十分的困,我便将闹钟的铃声给关掉了。之后,当第二次铃声响起的时候,已经六点四十五分了。我一看这时间,便吓得起了床,我的脑子里遍布都是“遭了,要迟到了!”

当我准备一切东西的时候,来到校门口已经迟到了,校长把我的名字和班级记在了本子上。当为回到教室的时候,又被老师训了一顿,这一整天,我都过得不好,上课的时候,因为熬夜的缘故,我便困得睡早了,结果当为趴在桌子上休息的时候,便被老师点名叫了起来,同学们顿时把目光放在我的身上,在那个时候,我低着头,感到无比的尴尬,我从来没有那么尴尬过。

当我苦恼先前的不愉快,还有现在依然都是困意的时候,我便知道了,这都是熬夜的结果。回想起来,如果我不熬夜的话,说不定我就不会遇到这么多不好的事情,现在也不会被点名站着上课了。哎,熬夜真不好。当放学回家的时候,我便决定了,坚决不熬夜了。我不想再迟到,然后在上课睡觉了。熬夜不仅对身体不好,还影响着我的生长。不仅仅如此,它让我的学习一片糟糕,让为上课不认真,学不到知识。一会想,熬夜的坏处不仅仅是为想得这么多,我们应该改掉熬夜是坏习惯。

当晚上的时候吃完饭,我坐在书桌的旁边时,目光扫了一眼那本课外书,我将课外书放进书桌的抽屉里,如何又从书包里拿出了一本课本。我将闹钟的铃声定在了晚上九点半,在这个时候,便是我要睡觉的时候。我开始决定了,以后晚上,坚决不看课外书熬夜了,我要养成早睡早起的好习惯,我要一个健康的身体,我要我的学习成绩提高。

熬夜的危害作文200字 第二篇

说到“熬夜”一词,想必人们都会联想到“吃鸡”,组团打“王者”或者聚会开PARTY之类的吧!但在我们学生时代,熬夜意味着——赶作业!

星期五晚上9:00刚补完课的我无精打采地进家门,吃力地走进自己的房间,将背上沉重的书包往沙发一甩,便像一个刚脱水的海绵,皱巴巴的瘫椅子上,四肢酸疼、大脑空白、感觉身体被掏空。在我眼前现有三大压力:1。作业堆成山:2。补习课赶场不停了:3。期中考试来临,明后两天是WEEKEND(周末),也是我每星期的末日,因为作业太多,补习课又压得我喘不过气来,作业无法完成!还不如天天上学!

所以,只能在周五晚上将作业赶完啦!(OH!MAGOD!)在我们学生观念来看周五晚上作业简直是丧心病狂!曾有一学生熬夜打作业仗导致心脏突发停止,瘁死!这可谓是“作死”啊!但身为“作业赶死队”的一员,我决定要写作业,赶完后便是人生赢家!

我将书包里的书本全部都抖了出来,按照作业布置分类,将作业本与有关资料书夹在一起,这样好拿多了!将它们堆在一旁椅子上,READY——GO!

NO1。数学!理科方面科目是我在学习中的克星,所以必须先干掉它们!我一会儿在作业本上奋笔疾书,一会在草稿纸上圈圈点点,划来划去;一张、两张、三张……十张,草稿纸即将用完之际,数学作业总算是干完了!

NO2。英语!哈哈!文科乃本姑娘一技之长!,在班上可有“英语小公举”的称号,当然分分钟英语作业也了事了!

NO3。生物!对于生物嘛!我也可以说是小菜一碟了!毕竟平时我对法医学有所关注和了解,长大也想成为一名痕检员,所以生物也仅仅花了十几分钟。

NO4。地理!我滴个神啊!又是理科!平时考试地理总不及格的我,对地理结下了深深的仇恨!它不仅仅是我成绩抹黑的一道铁门,又是我必学的科目!?打开地理作业本,哎!一眼望去,什么地势、温度带啊,气候啊,我一律不通,这叫我咋写咧?我咬着笔头看着题目,豆大的汗水从额间冒出,二十分钟过去了,仍然一字未写,我看了看钟——12:05!我更急了,在手中不停的翻着地理书,眼睛急切的寻找着答案,于是东拼西凑的写出了几个歪歪扭扭的答案,终于,写完了!

NO5。物理!又是理科?!我几乎崩溃!现已经是MIDNIGHT(午夜),神志模糊不清,咋还写的好呢?但是想起周末那么多补习,我哪能不做?哎!只能硬着头皮撞了!我的笔在书本上写着,笔晃来晃去,像在催眠我一般。我察觉到了不对劲,身体太累了,精神消耗过多了,加上一天学习,我的身子一定背不住,算了!写完了再睡,我强行抹了一点风油精在鼻孔下方,清醒多了……夜已深,凌晨三点时,我房间的灯终于熄了,我终于可以睡了……所谓“熬夜”便是如此,早晨七点起床赶课,脑袋依旧昏沉沉,四肢依旧酸痛,所以:NOZUONODIE!

熬夜的危害作文200字 第四篇

With the College Entrance Examinations approaching , the students of Senior Three are focusing much more on studying. Many of them even begin to stay up studying. A heated discussion was held to argue about the advantages and disadvantages of it.

Some students have their own reasons for studying late into night. Firstly, the quietness in the night will result in better effectiveness. Besides, the examinations are only 200 days away so it's high time they made good use of every minute. What’s more, seeing others studying so hard, they will feel anxious if they don’t take action.

Some others, however, hold the opposite view, saying that a sensible senior student must know how to balance his time between study and leisure. As everyone knows, staying up late will naturally affect the next day's performance in class.

As far as I’m concerned, different people have different habits. If you can hold it, it’s your own business when to study and when to sleep.

流星划过夜空,却没有留下痕迹。带我飞飞过绝望;

过了一会儿,外婆终于擦好了,但是姨婆的额头都是汗珠,围裙上都是水滴。看着她的逍遥哥哥与月如默契地练剑,灵儿又一次轻轻地笑了,静静地转身离去。硕果累累的秋天,我追寻那犹傲霜枝的金菊?”妈妈有些发火了。我也只好服从命令,让弟弟坐了上来。

她找不到方向;当我们生病时,大人们急得像热锅上的蚂蚁。树叶渐渐得枯萎了,被害虫叮得千疮百孔,而且树叶上也布满了厚厚的灰尘,压得黄桷树喘不过气儿了。说我太肤浅也好,说我太过于感性也罢,这便是我?再用吸水纸吸出叶脉上多余的染料,把它放在玻璃板下压平。

有一次,我的成绩考的不理想,挨了老师的批评。它们向东边走去,东边是一片树林,接下去还会发生什么事呢!我钻进被窝,蜷缩着,不干将头伸出,生怕有什么东西来咬我。高三综合症"似乎提前到了,下了课竟然会和四鬼子敲着饭盒唱《小白菜》"。“哎,今天是建党节呀!

这件事让我从中体会到了,一切都要自己做才会留下脚印。她一放学就如一阵风似的奔跑到我家。我这位“受害者”再度“被害”~~~~~~~~'?

熬夜的危害作文200字 第六篇

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.

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.

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.

熬夜的危害作文200字 第十篇

不好,长期通宵熬夜不睡觉的五大害处: 伤害一:免疫力下降 经常处于熬夜、疲劳、精神不振的状况,人体的免疫力会随之下降,感冒、胃肠感染、过敏等自律神经失调症状也会不期而至地找到你头上。而且经常熬夜带来的直接症候就是第二天上班头昏脑胀、注意力无法集中,甚至会出现偏头痛。 伤害二:肠胃危机 熬夜加班的人,很容易感到疲劳,吃“夜宵”可谓熬夜者的一大活力来源,但“夜宵”之后可能对胃有引爆的危机,却也让人不得不担忧,因为,人的胃黏膜上皮细胞的寿命很短,平均2~3天就要更新再生一次。这个过程一般是在夜间胃肠道休息时进行的。如果经常在夜间进餐,胃肠道得不到必要的休息,胃黏膜的修复就不可能顺利进行。而且夜间睡眠时,吃的夜宵长时间停滞在胃中,可促使胃液的大量分泌,对胃黏膜造成刺激,久而久之,易导致胃黏膜糜烂、溃疡。 伤害三:心脏病风险 研究显示,作息时间紊乱的人进行身体调适并不如一般人所想的那么容易,不仅脾气会变坏,得心脏病的几率也较高。因为人体的生物钟不受灯光、时钟的影响。尤其是像心脏等器官,也不会因为白天休息了,就做好了熬夜的调整,因此,若长期“黑白颠倒”,将会使人增加患心脏病的风险。 伤害四:肥胖 晚上9时后进食一般称作“夜宵”。人体内有交感神经与副交感神经两种自律神经。交感神经是在身体活跃的白天使消化器官频繁运作,促进消化吸收;到了夜晚,副交感神经活跃,在身体休息的同时,让摄取的营养素储存在体内。夜晚进食的话,不但会使人难以入睡,还会使隔日早晨食欲不振,如此造成的营养不均衡,就会引起肥胖。 伤害五:提神更伤神 一到要加班熬夜的时候,你是不是首先想到要来一杯咖啡或者浓茶提提神?咖啡因的确会让人精神亢奋,但是咖啡因对提升工作效率不见得有效,即使有用,也仅能维持短时间的效果。很多人在该睡觉的时候没有睡,而是*咖啡或是茶来提神,但是在夜晚人体的副交感神经活跃,使心跳速率及肠胃蠕动变慢,喝咖啡和茶都有刺激交感神经的作用,容易造成内脏的自律神经失调。咖啡因虽然提神,相对地会消耗体内与神经、肌肉协调有关的维生素B族,缺乏维生素B族的人本来就比较容易累,更可能形成恶性循环,养成嗜茶、嗜咖啡的习惯,而且需要量愈来愈大,效果愈差。 写作在英语学习中是培养和提高语言能力的有效手段,它有助于巩固和掌握所学词汇、语法等语言知识,有助于训练直接用所学语言进行思维,有利于提高驾驭语言的能力。中学生该如何写好英语作文呢?

熬夜的危害作文200字 第十一篇

Our school has regular rest hours for students. However, we can often see many students do their lessons or other things after the bed time. They usually stay up until midnight.

Teenagers need enough sleep daily. Staying up late may do harm to health. It can also make students late for class or sleepy in class. Thus, they miss something they should have learned.

It’s blameless to stay up once in a while if we do have to take up our rest time for some urgent deeds, but don’t make it a habit. President Xi recently advised young people not to stay up late, which we should bear in mind. Early to bed and early to rise makes a man healthy, wealthy and wise. We really need to make a change to the unhealthy lifestyle so as to ensure our rest time.

熬夜的危害

记得刚开学的时候,每天晚上作业很少,能在很短的时间内完成所有的作业,现在不行了,每天晚上都睡得很晚。

但是前几天在电视上看到一则新闻,让我现在不敢熬夜。新闻里报道说,一个年轻女孩因为熬夜,凌晨突然死亡。看完这个新闻,我心里一颤。

我知道虽然我现在没有熬夜那么严重,但是最近睡得很晚,我已经感觉到自己的身体发生了变化。感觉皮肤越来越差。我的脸以前很白,现在看起来蜡黄蜡黄的,跟营养不良一样。而且白天的时候,虽然清醒,但是感觉很累,知道是熬夜的结果。

过了这段时间我决定不熬夜了,一定要照顾好自己的身体。

第一次熬夜

第一次熬夜

半夜睡不着,把心情哼成一首歌,只好去楼顶找另一个梦。

夜深了,城市依然灯火通明。城市里彻夜未眠的灯光把云映成暗红色。

这里的高楼密集,挡住了我的远视。楼上的霓虹灯此时变得格外刺眼。不远处的桥上有车水马龙,灯光照亮了江面,清晰可见一条波纹。

在这个城市,即使是夜晚也令人不安。

在这样的夜晚,我似乎明白了很多。

灯光和烟火一起闪耀,无法照耀到城市最深处的黑暗。

这在你看来可能很正常,但对某些人来说却是一场灾难,一个死胡同。

暖黄色的路灯一盏接一盏的喊着,让居民们感到窝火,有的人甚至忍不住破口大骂。小贩一家三口住在路边的棚子里,日复一日的奔波,甚至深夜。婴儿不时会哭。在这个奶粉面临严重问题的地方,赚到的每一分钱对孩子都很重要。努力,努力。我表示无限敬意。

这样不好。一辆装有警车专用警示灯的汽车向小贩们驶来。

他们惊恐地看着自己的灾难,却心慌得不知如何是好。看着这一幕,我迫不及待的想保护这个弱小无辜的孩子。一群穿着制服的野蛮人醉醺醺地下了车。他们二话不说,打着执行公务的幌子,疯狂地抢夺小贩的财物。他们甚至把所有有用的东西都装进车里,冷冷地丢下一张票和一个白眼。

如果你看到有人有黑眼圈,毫无疑问,她昨晚熬夜了!但是,在我这只“夜猫子”的眼皮下,却丝毫不起眼,这大概已经成了我寒假的必备了吧。

“睡觉啦。”姐姐自顾自躺了下来,我不禁看了一眼时间:22:57.若是在平常,这个时候的我肯定已经进入了梦乡,倒头不起,这可是寒假!醒醒吧!我继续在电脑前奋斗着四篇作文,600字的作文。顶着黑夜眯着眼睛看着电脑上的字,搓了搓眼睛竟没有一点的睡意,我敲打着每一个键盘,不知不觉中,时间顿时飞到了0:00。我先是深呼一口气,看着床上已经开始做梦的姐姐,伸展了一下肩膀,又开始飞快地敲打着键盘,一个个字就这样显示在屏幕上,熬过了12点,接下来,还有什么能克服我呢?我想着,加快了速度,头脑不断地思考着,句子就这样如流水一般打在了word中,句子通顺,我顿时觉得脑细胞充足,啊!一定是熬夜给我带来的力量。呼!看见自己惊人的速度成果,我开始自恋起来:“我真是太厉害了,一下子就搞定了一篇作文,真是速战速决啊,比平常慢悠悠漫不经心的一小时好多了,想不到熬夜还有这种效果啊。提神充足脑细胞,果然不错哦。”接着,成语一个连着一个,句子一打就是一行,一篇文章就在我的熬夜下完成了,时间才0:44.我伸了个懒腰,哎!以前还真的没有这样熬夜过呢,第一次当夜猫子,却让我有了意外的收货啊。让我手指进行了“早操”活动后,又开始熟练的敲打这字母,这可是我的拿手活。时间又在悄悄地流逝,我一口气打了一半,终于抵不住眼皮向下掉的压力,合上了眼睛,靠在电脑前休息一会儿。过了一会儿,我就被电脑待机声吵醒,这才意识到还没有干完,开始了与熬夜的激烈搏斗。顶着一秒就会掉下去的眼皮,我有着巨大的压力,在压力中拼命的打字,脑子中的流水语言也悄然不见了,只看见我停下来的手指,不停的消除键,和我思考的话语。边打字边吃板栗,瞟了一眼电脑右下角的时间2点了。我居然熬到了两点!这真是个意料之外的事啊!我看着满满的一页字,点了一下保存,一头栽在键盘上,开始了我的睡旅。

太阳照在我的脸上,抬头看了看闹钟,十点了。是啊。十点了!熬夜的后果居然是十点!居然是十点!熬夜真是虚度了美好的学习早晨啊。

马上要上台表演了,我觉的两颊发热,热气不断上涌,摸摸脸,好烫呀。

会影响内分泌代谢不完全,造成皮肤水分流失,容易导致皱纹出现、皮肤暗淡、长暗疮、黑眼圈加重等,尤其是上完妆后情况会更糟,还可能会患脂漏性皮炎。熬夜的害处多多。因为人若经常熬夜最容易疲劳、精神不振,人体的免疫力也会跟着下降。感冒、胃肠感染、过敏等等都会找上你。更会慢慢地出现失眠、健忘、易怒、焦虑不安等神经、精神症状。过度劳累使身体的神经系统功能紊乱,引起体内主要的器官和系统失衡,比如发生心律不齐、内分泌失调等等,严重的就会导致全身的应激状态、感染疾病的几率相应提高。疲劳症状强烈的人比一般人患上呼吸、消化系统、循环器官等各种感染症的机会也增加许多。健康的生活习惯和有规律的睡眠可使体内的荷尔蒙正常分泌,从而保证生命器官在一个稳定的内环境中工作。正常 运行规律就会被打乱,激素的分泌规律也将改变,使生命器官遭受不同程度的损害,有人对长期熬夜的人和坚持早睡早起的人进行对照研 究,发现经常熬夜的人长期处于应激状态。

现在熬夜已经是许多人的家常便饭了,经常有人很晚很晚才睡觉。而且据统计,熬夜的人群也逐渐年轻化,更何况现在一些学生都开始熬夜,一两点才睡觉。

我姐姐就是一个例子。过年那几天,她的哥哥从外地来到她们家。她的。这个哥哥提着一个电脑来的,电脑里有植物大战僵尸,而且玩的级别已经很高了。姐姐对这个游戏也很着迷,就和他一起玩,一直玩到凌晨,才睡的觉。而我姐姐又是一个非常能睡的人,一睡睡到中午十一点。过了几天,她的另一个哥哥也来了,他也带来了一个电脑,电脑里也有植物大战僵尸,玩的级别也很高了。所以姐姐又和他一块玩,一直玩到凌晨四点钟。然后姐姐一直睡到下午两三点才起床。

大家看,我的姐姐把时间给搞反了,如果经常这样,身体能承受的住吗?我们儿童睡眠绝对不能低于六小时。如果低于六小时,在学习、工作方面就会有很大的影响,比如我们上着课就可能睡觉。后果会怎样?而我们也不能睡的太多,如果一天二十四小时全睡觉的话,那肯定是不行的。所以我们要养成早起早睡的好习惯,晚上早点睡,早晨也就能早起了。这样一天就能精神抖擞,学习起来,才能比较轻松、容易。

最后,提醒大家不要因为游戏或者什么诱惑打乱睡眠顺序,不要养成熬夜的习惯,要养成早起早睡的好习惯,这样对我们的身体才会起到帮助。

我每天静下心来一道题一道题的过,静的我感觉到心脏与秒针是一同跳动的,即便这样,到了最后一天的晚上还有一些没写完,我气得都快哭了,我尽力让我的每一个字都出现在秒针的下一步之前,我想同我写下的每一个字一起挽回十点钟,但它如期和妈妈一起来了。

“十点了,睡觉!”妈妈锁着眉头吼道,“明天开学了,收拾作业吧。”她特意加了一句。

我明白妈妈的意思,指把声音压得低低的嘟囔了一声:“还没写完呢。”

“早干啥呢”,这句话丝毫不留情面,说着,妈妈把灯一关出去了,现在,我都佩服妈妈的那股干劲,无奈,我只好上床。

我先用一个小马甲盖住台灯灯罩,使光线只朝作业不朝门,调整了好几次角度才好,我按开关时慢慢下去,再慢慢提手,听到一点点金属碰的声音,我的心就像刀割一样,同时屏住呼吸,好像爸爸妈妈是鬼片里的闻人味的怪物一样,我一呼吸他们就会感觉到。我终于开始写了,我做了周密计划,十五分钟一页,没写几个字我就看表,看用了几分钟,能节省下来几分钟喝点水也好,好不容易有时间,喝了口水也是冰的瘆人,但我又不敢出去倒热水,当时我的心情哪里是白毛女就能唱出来的。

我不知秒针已经转了多少圈,但它每转一周的过程我都看过。我的手心很僵硬,最后的字都能歪出纸面去,不知不觉中,窗外天色已慢慢亮了,我又开始用灯光照着太阳,就像电视上常出现的两个人运用法力双手一推推出两道光柱,然后一道光柱将另一道光柱抵下去,然我就希望我的台灯光把太阳光抵下去,但这显然是痴想。我害怕太阳光照着家人的脸上让他们起床。这样过了不久我第一次见证了完整的日出,我第一次进行了如此痛苦的熬夜,我找了一下镜子,把我自己都吓了一条,原来眼睛周围真的会有黑眼圈,我的脸上红得发亮,还油光光的,如果将来我会去下地狱的话,我觉得阎王爷会毫不吝啬将这第一次的熬夜算在地狱中度过的时间里,有了这次熬夜,我真的不敢再奢望作业前的任何娱乐时间了。

小学总不想睡是为了玩,而现在不能睡是因为玩,玩物丧志!我终于觉出了小学睡不着的夜晚,成就了我这第一次的熬夜。

熬夜的危害作文200字 第二十五篇

长期通宵熬夜不睡觉的五大害处:免疫力下降 经常处于熬夜、疲劳、精神不振的状况,人体的免疫力会随之下降,感冒、胃肠感染、过敏等自律神经失调症状也会不期而至地找到你头上。而且经常熬夜带来的直接症候就是第二天上班头昏脑胀、注意力无法集中,甚至会出现偏头痛。肠胃危机 熬夜加班的人,很容易感到疲劳,可谓熬夜者的一大活力来源,之后可能对胃有引爆的危机,人的胃黏膜上皮细胞的寿命很短,这个过程一般是在夜间胃肠道休息时进行的。如果经常在夜间进餐,胃肠道得不到必要的休息,胃黏膜的修复就不可能顺利进行。而且夜间睡眠时,吃的夜宵长时间停滞在胃中,可促使胃液的大量分泌,对胃黏膜造成刺激,易导致胃黏膜糜烂、溃疡。作息时间紊乱的人进行身体调适并不如一般人所想的那么容易,不仅脾气会变坏,得心脏病的几率也较高。因为人体的生物钟不受灯光、时钟的影响。也不会因为白天休息了,就做好了熬夜的调整,将会使人增加患心脏病的风险,人体内有交感神经与副交感神经两种自律神经”交感神经是在身体活跃的白天使消化器官频繁运作。在身体休息的同时,让摄取的营养素储存在体内,夜晚进食的话,不但会使人难以入睡。还会使隔日早晨食欲不振,如此造成的营养不均衡,就会引起肥胖,提神更伤神 一到要加班熬夜的时候。你是不是首先想到要来一杯咖啡或者浓茶提提神:咖啡因的确会让人精神亢奋,但是咖啡因对提升工作效率不见得有效?也仅能维持短时间的效果,但是在夜晚人体的副交感神经活跃。
