技术是有代价的。这不仅仅是货币成本。在本文中，我列出了使用或过度使用智能手机带来的一些与健康相关的成本。在使用智能手机时，您必须很聪明，否则您最终会遇到以下一种或多种健康问题。
(Health)智能手机引起的健康问题
文字颈(Text Neck)
Text Neck是医生或医师用来描述因过度使用智能手机而引起的脊柱疾病的术语。通常，如果头部直立，脊柱的颈部就不会受到压力。但在智能手机上阅读和发短信时，人们往往会将脖子弯曲到 60 度。这会增加颈部的压力。长期使用智能手机会引起与脊柱有关的颈部疼痛，因此可以称为脊柱疾病。根据发表在《华盛顿邮报》(Washington Post)上的一项调查，大约 80% 的成年用户患有这种文字颈部疼痛。
避免它的最好方法是将手机抬到眼睛的高度并直视它。你需要让它成为一种习惯，尽管它可能看起来很尴尬。另一种解决方案是降低你的眼睛而不是弯曲你的脖子。

视力下降(Vision Loss)
在智能手机上阅读小字体可能会永久干扰您的视力。出现此问题是因为您的眼睛经常因观看智能手机发出的蓝光而感到紧张。在没有外部光线的情况下阅读或使用智能手机进一步加剧了这个问题。你的视力变差了，你可能不得不戴眼镜。
避免这种情况的最佳方法是定期远离智能手机。在返回智能手机屏幕之前，看看远处的东西并专注于它一段时间。
手腕问题(Wrist Problems)
过度使用智能手机带来的另一个问题是手腕问题。我们长时间拿着智能手机的方式会使手腕紧张。人们通常用最后三个手指和拇指握住手机，同时用食指在智能手机屏幕上执行操作。每天保持较长时间的姿势往往会导致手腕疼痛。
在执行阅读等任务时，最好继续改变手机的姿势。您可以躺在床上或坐在椅子上的膝盖上放下智能手机，然后低头看它，而不是一直握在手中。

麻木的手指(Numb Fingers)
与上述问题类似，出于几乎相同的原因，智能手机用户的手指会变得麻木并产生刺痛感。握住手机会将压力从肘部转移到手指。肘部以上的手血液循环较慢，如果不立即纠正，可能会产生持久的影响。食指也有同样的经历，一段时间后变得麻木。
与其坚持同样的姿势，建议将手机放一会。然后做一些手臂和手指的运动，这样感觉就会消失。我建议在阅读或发短信时，每十五分钟使用智能手机至少一分钟。这将避免由于长时间使用而可能出现的永久性问题，例如在手机上看书时。

我只列出了四个可能由于长期使用智能手机而引起的健康问题。检查您是否沉迷于智能手机(addicted to the smartphone)——如果您认为自己沉迷，您可能需要考虑其使用模式。(I have listed only four health problems which may be caused due to using Smartphones for long periods. Check if you are addicted to the smartphone – and if you think you are, you may want to consider its usage pattern.)
Health problems caused by Smartphones overuse
Technology comes at a cost. It is not just about the monetary costs. In this article, I put down some health-related costs that come with using or overly using smartphones. In using smartphones, you have to be smart else you would end up with one or mоre of the following health problems.
Health problems caused by Smartphones
Text Neck
Text Neck is a term used by doctors or physicians to describe the spinal disorder arising out of excess usage of smartphones. Normally, if the head is placed upright, there is no stress on the neck part of the spine. But to read and text on smartphones, people tend to bend their necks up to 60 degrees. This increases the pressure on the neck. Long-term usage of smartphones bring forth neck pain related to the spine and hence, can be called spinal disorders. According to a survey published in Washington Post, around 80 percent of adult users suffer from this text neck pain.
The best way to avoid it is to bring up the phone to the level of your eyes and look straight into it. You need to make it a habit though it may look awkward. Another solution is to lower your eyes instead of bending your neck.

Vision Loss
Reading small fonts on a smartphone can disturb your vision permanently. This problem happens as your eyes are constantly strained by looking at the blue light coming out of the smartphone. Reading or using smartphones during the absence of external light further boosts the problem. Your vision becomes poor, and you might have to go for glasses.
The best way to avoid this is to look away from smartphones at regular intervals. Look at something far off and focus on it for a while before returning to the smartphone screen.
Wrist Problems
Another problem that comes with over usage of smartphones is the wrist problem. The way we hold smartphones for long durations strains the wrist. People usually hold their phones using last three fingers and the thumb while using the forefinger for performing actions on the smartphone screens. Retaining the posture for longer durations every day tends to create pain in the wrist.
It is better to keep on changing the posture of a phone when performing tasks like reading. You can put down the smartphone while lying on the bed or in the lap while sitting on a chair and look down at it instead of always holding it in your hands.

Numb Fingers
Similar to the above problem and for the almost same reasons, fingers of smartphone users become numb and produce a tingling sensation. Holding the phone places stress from the elbows to the fingers. The hands above elbow experience slower blood circulation and if not corrected immediately, can have long-lasting effects. The forefinger too experiences the same and becomes numb after a while.
Instead of persisting in the same posture, it is recommended to put the phone away for a while. Then perform some movement of arms and fingers so that the feeling goes away. I would advise keeping away the smartphone for at least one minute every fifteen minutes of usage when reading or texting. That would avoid permanent problems that may arise due to the persistence of prolonged usage like when reading books on the phone.
