为什么总是睡不好?十大常见睡眠错误
Most of us have struggled at some point with sleep. Whether it’s not getting enough sleepor struggling to get up in the morning, it can be difficult to get the balance just right.
大多数人都遇到过一些睡眠问题。有可能是睡得不够，又或者是早晨起不来，很难达到平衡睡得舒服。
However, sleep is essential if we want to be productive in life. It provides us with theenergy we need to get stuff done!
然而为了保证精力充沛，睡眠是十分必要的。我们需要睡足了才有精力干活!
Here are the 10 most common sleep mistakes people make and a few tips for avoidingthem!
下面列出了常见的十大睡眠错误以及纠正小贴士。
1. The snooze button
闹钟止闹按钮
Don’t EVER hit the snoozebutton. It really is much more beneficial to just get up on yourfirst alarm. Think about it – the snooze button gives you an extra 10 minutes or so sleep. Inthe grand scheme of your day this really won’t provide you with any more energy. In-fact itdoes the opposite. Research has shown that ‘interrupted sleep’ can cause us to feel moretired.
千万不要按止闹按钮，其实在闹铃一响时就起来对身体更好。想想看，止闹按钮可以让你多睡10分钟或者更长一点时间。但相比于一整天满满的计划，这多睡的10分钟根本无法为你多添几份活力。事实上恰恰相反，研究表明受干扰的睡眠会让人更加疲倦。
2. Disorganized sleeping habits
不规律的睡眠习惯
It’s much easier to get to sleep each night (and wake up feeling refreshed) if we have aregular routine. This means going to bed at roughly the same time each night and getting upat roughly the same time each morning. If you’re disorganized with your sleeping routine, youend up interrupting your natural sleeping rhythms, which can cause insomnia and fatigue.
如果每天的作息时间规律，每晚会更加容易入眠(醒来时也会感到神清气爽)。也就是说每晚在相对固定的时间睡觉，每天早上在相对固定的时间起床。如果你睡觉的时间不规律，就会打乱你的生物钟，导致失眠和疲劳感。
3. Long naps
小睡时间过长
Long naps can disrupt your sleeping rhythms so if you’re desperate for a nap then keep itunder the 30 minute mark (and before 4pm). Short naps after lunch can help to restore energylevels (just make sure you don’t sleep in).
小睡时间过长会打乱人的生物钟，所以如果你真的很想打个盹儿的话，请把时间控制在30分钟以内(而且要在下午四点前睡)。在午餐后小睡一会儿有助于恢复体力(只是不要睡过头了)。
4. Caffeine/stimulants
咖啡因/兴奋剂
Don’t drink any caffeinated drinks after mid-day. Caffeine stimulatesyour body for up to 12hours after consumption so it’s important to restrict your intake later in the day. Be aware ofsupposed ‘herbal’ drinks such as green tea, which can have a high dose of caffeine. Alwayscheck the label.
请不要在中午之后饮用含咖啡因的饮料。咖啡因会持续的影响人体12个小时，所以要控制自己不要在中午以后摄取咖啡因。小心一些“草本”饮料，例如绿茶含有很高的咖啡因。每次喝饮料之前都要看一下成份标签。
5. Stress &negative thinking
压力和消极想法
Stress is a large reason why many people find it difficult to sleep. One of the worse thingsyou can do is be stressed before bed. Stress produces chemicals that physically stop us fromsleeping. Try and clear your mind before bed time and make an effort to think positive thoughtsthat aid sleep.
压力是造成人难以入眠的重要原因。在上床睡觉前带着太大压力就更加糟糕了。压力会使人分泌出某些从生理上阻止睡眠的化学物质。尝试在睡前清空所思所想，努力朝有助于睡眠的积极方面想吧。
6. Too much light
光线太亮
Our bodies depend on ‘sleep signals’ to fall asleep and one of those signals is darkness.Make sure your room is as dark as possible before trying to get to sleep. Even a thin stream oflight coming in through your window can disrupt your pinealgland’s production of sleephormones and therefore disturb your sleep rhythms, so make sure your blinds are closed!
我们的身体依靠“睡眠信号”来入睡，其中一个信号就是黑暗。所以在睡觉前要确保房间光线尽可能暗。即便是透过玻璃窗射进来的一小束光线也可能会干扰人的松果体分泌睡眠荷尔蒙，从而干扰睡眠生物钟。因此要保证关上百叶窗!
7. Sugar before bedtime
睡前摄取糖分
Sugary snacks before bedtime are a really bad idea. The sugar can disrupt the chemicals inyour body causing you to wake up during the night. Limit all late night sweet treats – if you’rehungry go for a protein based snack instead.
睡前吃含糖的零食真的是个坏主意。糖会破坏人体体内的化学物质，导致人在夜间醒来。因此要控制晚间吃甜食的量，如果你饿了，去吃一些蛋白质为主的零食吧。
8. Alcohol before bedtime
睡前喝酒
Alcohol is a sedativeand therefore people get fooled into thinking it will help them get agood nights sleep. The reality is that it may initially induce sleep, however it usually drasticallyimpairs sleep during the second half of the night which leads to interrupted sleep patterns thatwill leave you feeling fatigued in the morning (not to mention the hangover!)
酒精有镇定作用，因此人们会误以为酒精能帮助睡眠。实际上酒精可能会在一开始促进人睡眠，但是它也常会在后半夜严重影响人的睡眠，打乱人的睡眠模式，让你在早上觉得很疲乏(更不用说还有宿醉了)。
9. TV in the bedroom
卧室里摆放电视
It can be easy to fall asleep on the couch in front of the TV. It’s important we don’t try andreplicatethis strategy in the bedroom though. The bedroom must only be associated withsleep. When you start to introduce mental stimulation such as a TV this can severely disruptyour sleep patterns.
坐在电视机前的沙发上很容易睡着，但重要的是我们不能在卧室里尝试这一 方法 。卧室应当只与睡眠有关，把电视机之类刺激神经的东西放进卧室会严重打乱你的睡眠模式。
10. Worrying about sleep
担心睡眠
If you’ve had a few bad nights sleep, then the worst thing you can do is worry too muchabout it. When we place too much focus on sleeping this can cause anxiety and only make theproblem worse. Try to go with the flow and let your body naturally get into a healthy sleeppattern.
当你几天都睡不好后，最糟糕的事情就是你还总是担心自己的睡眠。当我们把注意力过多放在睡眠上时，就会导致焦虑，而焦虑只会让睡眠问题变得更严重。试着顺其自然地让身体进入健康的睡眠模式吧。

5个有害健康的常见生活习惯
Everyday health hazard 1: Lying
日常健康危害之1：撒谎
Whether you’re complimenting your best friend’s unflattering hairdo or “improvising”on thecost of your new designer shoes, we all tell the odd fibfrom time to time. However, accordingto research, those little white lies could be more harmful than you think. Lying can generatefeelings of stress which are damaging to your health, and a study by researchers at theUniversity of Notre Dame found that when people reduced the amount of lies they told theysuffered from less headaches, sore throats and anxiety.
无论你是在恭维你最好朋友那不讨喜的发型，或临时冲动购物买下最新名牌鞋，在这时候我们通常会撒一些古怪的小谎。但是最新的研究显示，即便是那些无害纯洁的小谎言也会带来意想不到的危害。撒谎会产生压力，而压力会损害你的健康。一项来自圣母大学的研究发现，当人们减少说谎话的次数时，他们就会减少头疼、咽喉疼痛和焦虑的患病次数。
Everyday health hazard 2: Eating at your desk
日常健康危害之2：办公桌上吃饭
If you’re having a busy day in work, it can be tempting to skip your lunch break and eat atyour desk. However, missing out on breaks is not only bad for your stress levels, eating whiledistracted may also mean you are more likely to overeat. Furthermore, spending your lunchhour at your desk can lengthen the time you are physically inactive and also expose you toharmful bacteria. According to a study by the University of Arizona, your work station containsnearly 400 times more germs than the average toilet seat, making it a less than ideal place fordining.
如果你工作忙绿，你的午餐休息时间可能没了，就不得不在办公桌上吃午饭。然而错过了休息不仅会让你感到压力紧张，而且心烦意乱的你在这时候吃饭会导致你进食过量。此外，在办公桌上吃饭，你的身体不活动的时间就会增加，还会让你暴露在有害的细菌环境中。亚利桑那大学的研究 报告 显示，办公环境细菌量是马桶座圈平均量的400倍，你还想在这样的地方进餐吗?
Everyday health hazard 3: Housework
日常健康危害之3：家务
Need an excuse to put your feet up? Well, good news: research suggests that leaving thehousework for another day could give your health a boost! Research results published in theJournal of Family Psychology revealed that doing housework when you get home from workprevents levels of cortisol (the stress hormone) from lowering and reduces recovery fromstress. However, stress levels for both men and women were lowered by housework beingcompleted – just so long as they weren’t the ones doing it. Look after your health by takingturns to do the housework with other members of your household if possible, and take timeout to relax afterwards.
想找个理由不做家务?那有好消息了：研究显示，人们把 家务活 留到第二天做，身体会更棒!《家庭心理学》刊登了这篇研究报告，报告结果显示，当你下班回家后做家务活，皮质醇(压力荷尔蒙)的释放会被抑制。皮质醇能降低压力，还能缩短受压后的恢复时间。但是当家务被完成后，男性和女性的压力水平都会降低——只要做家务的不仅仅只有他或她。可以的话，你可以和家人分担家务，这样能让自己保持健康，还有家务过后记得要抽时间休息啊。
Everyday health hazard 4: Using cash machines
日常健康危害之4：使用自动提款机
Withdrawing money from ATM machines is a common habit for most of us. However,cleanliness tests in Britain have revealed that cash machines are just as dirty as public toilets,and many of us are failing to wash our hands after using them. Experts assessed swabs fromthe key pads on cash machines and also from nearby public toilets and found that they bothcontained the same types of bacteria known to cause sickness. To look after your health, usean antibacterialhand gel once you have made your withdrawaland after handling money.
从自动提款机中提起现金是大多数人的日常习惯。然而一项英国的洁净测试显示，提款机和公厕一样脏，而且，大多数人在使用后都不会去洗手。专家们在自动提款机的键盘和附近的公厕中提取了样品，发现两者均含有同样致病菌。为了您的健康，请在提款和处理钱款后使用抗菌洗手液清洗。
Everyday health hazard 5: Cancelling plans
日常健康危害之5：取消计划
Find yourself frequently cancelling plans and bailing out on social events to have a bit oftime to yourself? Then it may be time to pay some attention to your social life. While a bit of‘me time’ is essential to good mental and physical health, too much time on your own canactually be bad for you. Research suggests that having strong social bonds promotes brainhealth, reduces feelings of depression and stress and encourages you to look after yourhealth. In fact, a study found that having few friends affects your longevityas much as smoking15 cigarettes a day.
发现自己频繁取消计划，还想摆脱社交活动，只为挤出属于自己的空闲时间?那么现在是时候在自己的社交生活中多多用心。拥有少量属于自己的时间，对于精神和身体方面是非常有益处的，但是太多属于自己的时间，反而有可能会害了你。研究显示，较强的社交联系有益于大脑的健康，同时能避免抑郁、降低压力，还能鼓励自己多关注自身的健康。事实上一项研究发现，没有朋友也会减少你的寿命，效果相当于1天抽15根烟。

睡前玩iPad会影响睡眠质量
Using tablet computers like Apple’s iPad and Samsung’s Galaxy Note just before bed can lead toa poor night’s sleep, according to research.
More and more people are taking their tablets to bed with them to surf the web, checkFacebook or email before switching off the light.
But researchers are warning that the blueish light their screens emit can stop users getting agood night’s sleep.
That is because this type of light mimics daylight, convincing the brain that it is still daytime.
Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep.This is because our brains have evolved to be wakeful during daylight hours.
By contrast, light which is more orange or red in tone does not suppress melatoninproduction, perhaps because our brains recognize it as a cue that the day is ending.
Neurologists have known for years that staring at screens late in the evening can disrupt sleep- be they television screens, computer screens or mobile phone screens.
However, because mobiles and tablets are by nature portable - not to say addictive - morepeople are taking them into the bedroom.
Users also tend to hold them much closer to their eyes than a computer or television screen.
Researchers at the Lighting Research Centre, at the Rensselaer Polytechnic Institute in NewYork, are warning that looking at tablet displays for more than two hours “leads to asuppression of our natural melatonin levels as the devices emit optical radiation at shortwavelengths” - in other words, they emit bluer light.
They say: “Although turning off devices at night is the ultimate solution, it is recommendedthat if these devices are used at night displays are dimmed as much as possible and that thetime spent on them before bed should be limited.”
They drew their conclusions after measuring melatonin levels in 13 volunteers, after they hadspent time viewing iPads at full brightness at a distance of 10 inches, for two hours.
Melatonin levels were significantly lower after they had done this, than they were after thevolunteers had viewed their iPads for the same time, but while wearing orange glass goggles,which cut out the blue light.
They wrote in the journal Applied Ergonomics that tablet makers could "tune the spectral powerdistribution of self-luminous devices" so that they disrupted the sleep patterns of users less.
It is not just a good night’s sleep that could be jeopardized by too much late night screentime.
Researchers know that persistent disruption to sleep patterns can lead to an increased risk ofobesity, and even breast cancer.
However, these studies tend to be comparisons of those with chronic sleep disruption, suchas long term shift workers, with those who have normal sleep patterns.
科普 教育 对我国小康社会、和谐社会的建设有着重要的意义， 科普知识 的传播是很必要的。下面我为您带来小学生科普主题征文400字 优秀 作文 ，一起来欣赏一下吧。

星期一下午，我在家里看了一本书叫《游戏中的科学》。我翻了几页，看到有一篇能让葡萄干浮起来，而且能让它上下浮动。我心想：这个实验挺有趣，试试吧。于是，我就开工了。
我照着书找来了几粒葡萄干、一杯水、一瓶醋和小苏打。实验开始了，我按照书上写的，先把几粒葡萄干放入水中，便马上沉在水底了。我接着加了一小勺小苏打和几滴醋。紧接着，奇迹发生了!葡萄干浮起来了!但刚浮到水面又沉下去。可刚沉到水底，又浮了上来。就像在上下舞动，真有趣!可心的问题来了：为什么葡萄干能上下浮动呢?
我带着问题再次阅读书本，原来醋和小苏打能变成二氧气碳，产生汽泡，气泡附在葡萄干的表面，使葡萄干变轻，浮到水面下。刚浮到水面，气泡破了，葡萄干再次下沉，收集气泡，气泡够了，葡萄干再次浮上来，这样上上下下，就像欢快地跳舞。
连一个小小的实验都有这么多学问，那么，大自然还有更多事情，正等着人类发现呢!

忙碌了一个月的科普节活动，今天终于要见分晓了。我们的小发明，小制作，金点子，科技小报科技画展板，包括知识竞答赛的活动都会画上一个句号，但是，这个句号显得那么的不完美……
成绩是在今天的知识竞赛活动结束之后，陈校长公布的。因为当时杨老师在场，我们才勉强安静下来听的。“获得小发明一等奖的是……”虽说我们是“勉强”，但此时此刻心中的那根弦还是绷得紧紧的——这关系到班级的荣誉，我们必须听着。小发明，小制作的名单终于公布完了，我们班破天荒的竟只有一根独苗——周锦愉，获得了小发明的三等奖。我们几乎是大吃一惊，但我同时愿一落千丈的心也变得有了许多期望填充在里头——我很希望接下来获得金点子优秀奖的名单里有我一分。名单依次报下去，每报一个，我的希望仿佛就落空了一些。此时，我好希望那份金点子的名单永远不要报完，因为我担心，我害怕，甚至已经相信那份名单里没有我。
名单还在依次地报，好像故意在吊我的胃口，六( 3 )班的一个也没有，反倒是六( 1 )班的，成绩赫赫，把我们比得恨不得钻到地下，简直是无地自容了。或许就是六( 1 )班太强了，而我们就显得十分差劲……
就像杨老师说的一样，“付出了多少，就会收获多少。”“六( 3 )班缺少一种凝聚力。”
这次科普节我明白了许多，我想他将会留在我的记忆深处。

每一个人都有自己的一个梦想，不过，有大有小，当然，对于我们这些正在学习成长中的孩子们来说，更应该向自己远大的理想一步一步的迈进，向成功“进军”吧!
当我看到中国最近发射的神舟十号成功登天时，刹时，就给了我极大的震撼，特别是王亚平老师与我们面对面的太空授课。
王亚平老师先讲了太空中失重的问题。特别讲到了一个水球实验老师先拿了一个圆形的工具，放了一滴水在里面，我真担心小水珠会掉下来，当然不会!因为水在太空失重环境下，是不会掉落的，反而会成为水珠，轻轻漂浮着。老师取水也是很讲究的，要用吸管从一个水袋里挤压出来。紧接着，老师又在原来的基础上往里面一滴一滴地注入水滴，水球越来越大，始终都不会掉下来，后来老师又往水球里注入一些红颜色的液体，眼看着，红色在水球中往四面八方蔓延着。很快，透明的水球变成了红色的水球。最后，让我们来看看怎么把水球“消灭”吧!只见老师拿出了一块大纸巾，一挤“啪”，水球消失了，后来，老师还讲了一些其他的科学现象。
听完.看完了这堂课，我觉得太空真是太奇妙了，于是，我对自己说：我从现在开始，我一定要努力学习，长大也成为一位太空员，去探索太空其他的未知领域。
