On June 25, according to foreign media, Forbes, current smartphones work and frequent use has been threatening to users ' health. Even medical workers to create a proper noun, "temporary blindness in Smartphone." In a recent New England Journal of Medicine (The New England Journal of Medicine), a United Kingdom medical team published an article describing the two women temporary blindness due to smart phones. Doctors found that the cause is using an eye in the dark using smart phones for a long time caused by a temporary phenomenon. In recent years, the Smartphone popularity and frequent use makes their impact on human health is growing, and its influence is not just with the eyes.

On "temporary blindness in smart phones", because the user was lying on his side in bed using posed by Smartphones, the key is patient while lying in bed, one eye pillow block, with one eye looking at mobile phones. Author points out, "we speculate that blindness symptoms are due to different light Photoreceptor cell cause irritation of the eyes. In the case of one eye for a long time using smart phones, an eye watch phone adapted to mobile phone light pillows of shielding eyes adapted to the dark environment. Subsequently, the eyes in the darkness, adapt to the intense light of blindness in that eye will appear. This will last for a few minutes, reflecting the eye going through sensitive stimulation after a gradual process of recovery time. ”

In other words, when you use a smart phone with one eye, your eye Photoreceptor cell adapted to light stimulation, this makes the photoreceptor cells sensitive to light than the other eye. This environment back to the room just like in strong sunlight conditions. You have a couple of minutes in a State of blind until the eyes to adapt to the ambient light. And the same thing will happen to you with only one eye, a smart phone, you lift up your head, you can feel "blind". Lucky is that this is temporary, and brings only anxiety rather than dangerous.

Sleep problems

One-eyed blindness was in bed one of the hazards of using smart phones. In fact, there are other factors that can have more impact on the body. Smartphone and Tablet PC screen will have a Blu-ray, which can affect our sleep cycle. This situation occurs because the Blu-ray production of melatonin reduces brain, melatonin is one of the key factors of sleep. Medical research shows that this will not only suppress the body's hormone production, and use tools to automatically defer sleeping on the bed. Use smart phones can disrupt hormones, can also make falling asleep more difficult. Sleep experts usually recommend, one hour before going to bed to turn off the phone, your nervous system to relax and sleep calibration.

Organisms do not apply

Such as "SMS neck" or "cell phone elbow", and so on in the medical community has been defined in the past few years. Massage dienfeishiman in contact with many young people neck discomfort due to prolonged mobile phone use, proposed "message to my" description. When a long time bending the neck occurs check "message to my" symptoms. And when you hold the phone attached to the ear for a long time when you call, there will be "cell phone elbow" problem.

Walking and texting

In some cases, when using the phone without looking at the front may result in bodily injury or even death. Texting while driving is the deadliest and texting while walking is also a great harm, it's more harmful than talking on the phone as she went, because when the text you can't see where you want to go. Researchers noted that texting while walking is not only makes walking slower or will deviate from the course. While studies show that damage caused by texting walk more and more every year, even leading to death.

Use

Perhaps smartphones the biggest danger is that their potential addiction. In a recent poll, 50% children and 27% parents obsessed with Smartphones. About cell phone addiction is not clearly defined, but in fact this does exist. Internet use has begun to be United States Psychiatry Association to conduct in-depth studies on smart phone addiction research is also not too far away. Because as addictive behaviors and substance, many people will frequently check their phones, it is easy to imagine cell phone addiction has become a widespread problem.

Both mental health and physical health, and consciously reduce cell phone use or a better method. Unless you really need to carry a cell phone, or on his cell phone at home while you are out or at home on his cell phone in the other room, I put it in the bag at work. Never put the phone in bed or lying on the bed using a mobile phone. Smart phones are useful and interesting, but when it affects our lives, requires that enough is enough.

6月25日消息，据国外媒体福布斯报道，目前智能手机在工作和生活中的频繁使用已经危及到用户的健康。医学工作者甚至为其创造了一个专有名词，“暂时性智能手机失明”。在近期的新英格兰医学杂志（The New England Journal of Medicine）中，一个英国医学团队发表文章描述了两位女士因智能手机导致的暂时性失明现象。医生经研究发现，病因是在黑暗中使用一只眼睛长时间使用智能手机所造成的暂时性现象。近几年来，智能手机的普及以及频繁使用使得其对人类健康的影响与日俱增，而其对人体的影响不仅仅是眼睛。

关于“暂时性智能手机失明”，是因为用户侧身躺在床上使用智能手机所造成的，问题的关键在于患者躺在床上时，一只眼睛被枕头遮挡，而只有一只眼睛看手机。论文作者指出，“我们推测，失明症状是由于不同的光线刺激眼睛感光细胞导致。在长时间一只眼睛使用智能手机的情况下，观看手机的一只眼睛适应手机光线，而被枕头遮挡的一只眼睛适应了黑暗环境。随后，但双眼在黑暗中时，适应强光的那只眼睛就会出现失明。这种差异将会持续数分钟，反映了眼睛经历感光刺激以后逐步恢复的时间过程。”

换句话说，当用一只眼睛使用智能手机时，你这只眼睛的感光细胞在适应强光刺激，这使得相关的感光细胞对光线比另一只眼睛敏感。这就像在强烈的阳光照射环境回到室内的情况。你有几分钟会处于失明的状态，直到眼睛重新适应环境光线。而同样的事情也会发生在你仅用一只眼睛看智能手机时，你抬起头，会感觉“失明”。幸运的是，这是暂时的，带给人的仅仅是不安而不是危险。

睡眠问题

独眼失明现象只是在床上使用智能手机的危害之一。事实上，还有其他因素会给人体带来更多影响。智能手机以及平板电脑的屏幕都会产生蓝光，这会影响到我们的睡眠周期。出现这种情况的原因是蓝光会减少人体大脑褪黑素的产生，褪黑素是人体进入睡眠状态的关键因素之一。相关医学研究表明，这不仅会抑制人体激素的分泌，而且在床上使用工具会不由自主地推迟睡眠时间。使用智能手机会扰乱荷尔蒙分泌，也会使入睡更加困难。睡眠专家通常建议，在睡前一个小时就要关闭手机，让自己的神经系统放松并进行睡眠校准。

机体不适

像诸如“短信脖”或“手机肘”等问题在医学界已经在过去几年内得到了定义。按摩师迪恩菲什曼在接触到诸多年轻人因长时间使用手机而造成的脖子不适后提出了“短信脖”的描述。当一个人长时间弯着脖子看手机时就会出现“短信脖”的症状。而当你长时间拿着手机贴到耳朵旁边打电话时，就会出现“手机肘”的问题。

边走边发短信

在有的情况下，使用手机时不看前方可能导致身体伤害甚至死亡。开车时发短信是最致命的，而边走边发短信危害也很大，这要比边走边打电话的危害更大，因为当你发短信时不能看到你要往哪里走。研究人员指出，边走边发短信不仅使得走路变慢，也会偏离路线。同时研究表明，每年因走路发短信造成的伤害越来越多，甚至有因此导致的死亡发生。

使用成瘾

或许智能手机最大的危害在于其潜在成瘾性。在最近的民意调查中，有50%的孩子和27%的家长沉迷于智能手机。关于手机成瘾并没有明确定义，但事实上这种情形的确存在。互联网使用障碍已经开始被美国精神病学协会进行深入研究，而对智能手机成瘾的研究也不会太过遥远。因为行为和物质一样会使人上瘾，介于许多人都会频繁检查自己的手机，不难想象手机成瘾已经成为社会普遍存在的问题。

无论对于心理健康还是身体健康，有意识地减少手机使用或是一个好的方法。除非你的确需要随身携带手机，否则外出时就把手机放在家中，或者是在家时就把手机放在另外一个房间，在工作时就把它放在包里。绝不要把手机放在床上或者躺在床上使用手机。智能手机是有益有趣，但当它影响到我们的生活时，就需要适可而止。
