读了《艾滋病小斗士》这篇文章,我的感想很多。恩克西那顽强地向病魔抗争的精神和无论遇到多大的困难都能乐观、坦然地去面对的态度深深打动了我。
文中令我印象最深的一句话是“他一边顽强地与病魔作斗争,一边关心和他一样患病的儿童”因为我觉得恩克西能顽强地与病魔作斗争已经是常人所不能及的,他还能在病痛缠身的同时,仍然想着为他人,尤其是和他一样患病的儿童。
恩克西在患病期间曾经应邀到美国出席艾滋病研讨会,呼吁世界要关心、爱护艾滋病患者。他还在南非举行的国际艾滋病大会上发言,向人们呼吁要关爱艾滋病患者,要用爱拥抱艾滋病儿童!恩克西那尚显稚气而又坚定的话语震撼了参加会议的各国代表的心灵。
和恩克西他那柔弱的身躯相比,我们是幸运健康的同龄人;和恩克西为他人照相并为其他患者而不惜竭尽所能的表现相比,我们更多的是只关注自己,而很少关心他人。其实,在我们的身边就有许多人需要我们的关爱,比如:同学生病了,我们应该送上关切的问候,或者力所能及地帮他带带作业、补习功课;路见年迈的老人行动不便,伸出手来帮他提提手里的重物、搀扶他们过马路;公交车上主动给老弱病残让座位;要下雨了,提醒邻居赶紧收晾在窗外的衣物;看到小弟弟妹妹摔跤了,赶紧上前扶起来……这些事儿对我们来说都是举手之劳,而我们做的并不够,甚至还有人常常视而不见!恩克西的事迹给了我们榜样,作为同龄人的我们要主动关爱那些需要帮助的人,哪怕是微不足道的一件小事,比如一个拥抱、一句问候、一个温暖的眼神……我们都应该尽量做好,就像恩克西那样!
在呼吁大家关心别人的同时,我默默地告诫自己:要以身作则,首先珍惜现在拥有的`一切——健康的身体,幸福的生活;然后,主动地关心是我们身边的亲人、老师、同学;我们还要身体力行地为其他需要帮助的人,比如路上的行人、灾区的同学等送上最诚挚的关爱,让他们都会因为我们微不足道的爱而倍感幸福。
相信恩克西能做到的,我们都能做到!人人都付出一点爱,这个世界将会变得更美好!
艾滋病,一个刺痛双眼的词。
艾滋病人,一群需要我们特别关爱的患者。
忘记了是从哪一天起,“艾滋病”这个略带西方色彩的词闯入了我们的生活,它惊醒了沉睡中的人们,让我们认识了“艾滋”,了解了“艾滋”,惧怕着“艾滋”,远离了艾滋病人。
人性,需要在这个时候得以体现;人性,就在这个时候体现出来了。濮存昕这个人我不太熟悉,说实话,他的名字我都不会写(还是通过问爸爸妈妈再上网查证后记下来的),可是我从心底里崇拜他,因为他有着高尚的灵魂,一颗晶莹剔透的心。听说他是有名的艾滋病形象大使,我国第一个艾滋病预防宣传员。他真心关爱着这一群特殊的患者。正因为有爱,濮存昕才更加热爱公益事业。在拍完《假如有明天》这部戏以后,他把所有的片酬都捐给了北京佑安医院。他想用这个来协助这所专门治疗艾滋病的医院。从2000年接受卫生部之邀,出任艾滋病宣传员起,他运用自己的影响力和感召力,号召全社会重视艾滋病,关爱艾滋病患者,并身体力行地从精神上或者经济上帮助艾滋病患者和他们的家庭。几年内,濮存昕做了大量工作:拍公益广告、出演有关艾滋病的电影、对社会公众或政府机构人员做讲座和培训、在政协会议上提交有关提案等等。所有这些工作,他希望达到的这样的效果:一是引起社会对防治艾滋病工作的重视;二是呼吁社会关心艾滋病病人。
其实我心里也知道,艾滋病并不像传说中的那么恐怖,它主要是靠性传播、血液传播及母婴传播这三种途径传染给他人的,可是由于人性的自私,我惧怕艾滋病。如果说有一个艾滋病人站在我面前表示想要跟我握手,我是不是能勇敢地伸出自己的手?可是濮存昕,他毫不犹豫地和艾滋病患者握手、吃饭、交流。也许这对于正常人与正常人之间太微不足道了。可是如是对方是艾滋病患者,请问,你能像他一样吗?我想我恐怕真的做不到。
人之初,性本善。也许是自私抹杀了我们的善良,也许是自我保护意识让我们收起了爱心。
我多想在这里高声夸赞那些能做到和艾滋病人平等相处的人:你们,真了不起!
有一种精神让我们泪流满面;有一种力量,让我们信心倍增;有一种人格,让我们不断追求自我完善,让我们共同学习恩科西精神,建设被病毒破坏的和谐。
“珍爱生命,抗击艾滋”多么嘹亮的口号,虽然只是八个字,但却是寓意非凡。人的生命是有限的,而病菌却一点也不同情人类,还一次又一次的吞噬人类的生命。虽然人们尽了最大的努力消灭病菌,但是一种严重传染性疾病却永远也没有消灭。
这种严重传染病是人们常用恐怖、未知来形容的艾滋病,医学名叫“获得性免疫缺乏综合症”,英文缩写“AIDS”。艾滋病的病毒到人体之后,病毒在体内不断复制,而且破坏人体自身的免疫力,潜伏期长达8–10年,当人体免疫功能被破坏后人就一直得病,时间长了,只有死亡。
在参加这次活动之前,我对艾滋病知识的了解也存在不少误区,认为握手、打喷嚏、共同进餐就会感染上艾滋病病毒。现在我知道了艾滋病病人需要关怀和理解,你可以和他们热情的握手,可以和他们近距离的交谈,可以和他们交朋友,不能远离他们、歧视他们。
艾滋病是一个健康问题,同时也是一个社会问题,社会中的每一个成员都有可能成为艾滋病流行的直接或间接受害者。艾滋病对个人、家庭和社会都造成不可忽视的危害。
艾滋病使千千万万的儿童沦为孤儿,使千万无辜儿童被迫承受失去亲人的痛苦,还要经常忍受人们的歧视、失学、营养不良以及过重的劳动负担。
看!雄狮已醒,人类再也不会向病魔屈服,医学人员的奋力拼搏,艾滋病患者的顽强斗争,我们再也不会看到他们艰难地挣扎在生死线间,看到他们满面烟火的脸上悲伤的表情,看到他们眼中的热泪,看到他们凄凉的微笑。
1988年,世界卫生组织规定,每年的12月1日为“世界艾滋病日”,1996年以后更名为“世界艾滋病宣传运动”。每年12月1日前后,全世界各地围绕艾滋病的预防与控制和统一的宣传主题,开展形式多样的宣传活动。
我们在12月1日这一天里,大声喊“珍爱生命,抗击艾滋”,让这句话唤醒全世界,让全世界都向艾滋宣战,我相信在未来的一天,我们一定将艾滋打得不堪一击!世界一定会成为一个无毒世界、绿色世界、健康世界。
让我们一起为之付出行动吧!
1988年1月世界卫生组织在伦敦召开了有100多个国家卫生部长参加的高级会议,把每一年12月1日作为全球宣传防治艾滋病的日子,称之为世界艾滋病日,把每一年的12月1日都被作为世界艾滋病日,以号召全球人民行动起来,充分发挥全社会的作用,克服艾滋病。本周三是第22个世界艾滋病日。今年世界艾滋病日的主题依然是遏制艾滋、履行承诺,夸大权益、责任、落实。
艾滋病的医学全名为取得性免疫缺陷综合征,是由人类免疫缺陷病毒(HIV,又称艾滋病病毒)引发。通俗地讲,艾滋病就是人体的免疫系统被艾滋病病毒破坏,令人体对要挟生命的各种病原体丧失了抵抗能力,从而发生多种感染或肿瘤,最后致使死亡的一种严重传染病。
这类病毒毕生传染,破坏人的免疫系统,令人体丧失抵抗各种疾病的能力。当艾滋病病毒感染者的免疫功能遭到病毒的严重破坏、以致不能维持最低的抗病能力时,感染者便发展为艾滋病病人。艾滋病病毒在人体内的潜伏期均匀为12年至13年。在发展成艾滋病病人之前外表看上往正常,他们可以没有任何症状地生活和工作很多年,便能够将病毒传染给其他人。艾滋病目前还是不治之症,至今还没有药物可以治疗,更没有疫苗可以预防,是当前医学界最关注的一种传染病。因此,它有世界瘟疫之称;又因侵害性严重,被称为超级癌症。
固然如此,艾滋病还是可以预防的。艾滋病病毒对外界环境的抵抗力较弱,离开人体后,常温下只可生存数小时至数天。100℃20分钟可将其完全灭活、干燥和经常使用消毒药品都可以杀灭这类病毒。一旦皮肤被划破并有接触病毒的危险,最简单有效的方法是把伤口表面的血液挤出来,然后用消毒剂清洗,假如没有消毒剂,用肥皂或大量的净水冲洗也可下降被感染的可能性。艾滋病毒主要是通过血液和母婴转染的,因此,明哲保身,不与多个同性或异性发生性关系,不使用不经消毒的注射用具等预防措施就显得非常重要。因此,预防艾滋病的重点在于普及防护的基本知识,采取防护措施、控制流行、制止蔓延,这已经是当务之急。
有人说每一颗流星的下坠,就代表着一颗心跳的停止跳动。如果世上再也没有了脉搏的跳动,那么黑夜是否也一样暗淡无色?生命的消逝,不仅是一种美丽的丧失,更是一种悲痛的源泉。
无法言明的悲痛,就像伤疤,也许会好,但也会留下淡淡痕迹。
让人经不住惆怅的望望天空,是什么导致生命的脆弱易折?没有回答,风刮过,似乎在说,生活中…哦,是重病,是事故,亦或是那不在乎的心理。医学史上,有一种名为艾滋的病。他被称为“史后世纪的瘟疫”超级癌症”和“世纪杀手”。从名字不难看出,他是一道难题,一道治愈的难题。
大千世界,无奇不有。就是这个被断定为绝症的病症,如同一张死亡录取单,某些人就逃掉了。无论是从生理,心理来说,他们都是非常坚强的。他们可以忍受病痛的折磨,可以忽略别人的排挤,可以面对树叶随时凋零的危险,而坚强的活下去,笑着活下去。他们如同悬崖边上带着刺的玫瑰,危险,但娇艳。
通过调查,你可以发现,患艾滋的病人有大多是生活不讲究,甚至不重视生命的人。艾滋可以多方面传播,一个小小的细节,也许就会酿成难以预知的后果。年轻的人喜欢新潮,追随着潮流的尾巴奔跑。尝试着一切刺激而新鲜的事物,满足自己的好奇心。有句话说,好奇心害死一只猫。假如患艾滋是某些好奇的后果,那他不一定带给你死亡的解脱。它更会给你带来痛苦。如同一个喝醉的人过独木桥,摇摇摆摆,但又不曾落下,也不曾真正的踏稳。又好似悬挂在枝头的树叶,摇摇欲坠,落下是被践踏的痛苦,留下是被虫啃噬的折磨。
艾滋,看似离我们很远,但请知道,他一直都潜伏在我们生活中,在某一个不为人知的角落,滴落着垂涎的口水。或许在某一次旅行或游玩,就踏入了他的虎口生活就是一场临时编策的剧本,你并不知道下一刻的危险在那里。这是无奈的,踏出的一步也许有危险,但又不得不往前走,一直走到生命的尽头。所以,我们要处处留心脚下,不要因为迷恋花丛中带有斑斓花纹的美丽蝴蝶,美丽是一个陷阱,蛊惑人的陷阱,从而就会盗走你的生命。
请好好珍惜生命吧。话虽简单,人所共知,可真正理解的又有多少?这也许就是人性的弱点,只有牺牲以后才能永垂,只有残缺之后才懂完美,只有经历过才能后悔。

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.
