周末,人们为什么会感到无聊?

                 周末,人们为什么会感到无聊?

                    2016-10-24 上海宜鑫化工

  总有人时常抱怨自己感到无聊。

  不久前,一项针对人们生活状态的调查显示,在接受调查的人群中,约有半数的人会在家中或学校感到无聊;同时,更有超过三分之二的人,长期在工作中感到无聊。有着上述状态的人在我们的身边比比皆是。但实际情况却是,当下的智能手机、无线网络、社交媒体无处不在,人们的生活本该丰富多彩,又怎会产生无聊之感呢?就小编个人来说,我曾也有这种无聊不知所措的时候。但是不要让自己长期处于这种无聊不知道自己要什么,该干什么的状态下。因为你的彷徨只会给你的生活带来负面的影响。然而我是如果走出这种状态的呢?有没有听说过:你处在的地方取决了你的朋友圈什么样的?而我,身边并没有什么惊奇的人物。只是我的两个室友,他们看到我很迷茫,人生没有方向的时候,很主动很不吝啬地找我谈话,把我从深潭中拉起来。现在的我感觉很轻松,做什么事都很起劲。所以不要让你的朋友圈限制在几个人,人都是有感情的,而这种朋友情会帮助你的事业。

  导致这种无聊情绪出现的原因有很多,但其中一种已为世人普遍认可——人们的感官被过度刺激了。具体来看,在接受新鲜事物的刺激时,人们的大脑中会生成一种多巴胺,它可以令人产生愉悦的感觉。虽然一些新鲜事物的出现,的确在一时给人们带来了刺激,但随着时间的推移,以及这种感觉的逐渐消退,习惯于不断被其刺激的人们,会变得上瘾一般地迫切需要更多新鲜事物的出现,以维持并提升这种内心深处的满足。因此,一旦这种满足感无法得到及时补充的话,人们就会不自觉地产生无聊之感。前天,我在图书馆看了一遍关于孔子人物的特绘来反映自身对这个社会的一种看法,以及一个正真有社会意识,知深的人气质谈止对待生活和身边的人的一种态度。里面有句话我感觉特别有深度:老子的高度,幸福的深度。

  而这种满足感的缺失,则与人们对屏幕愈发依赖有着莫大的关系——今天,借助于网络及其各种媒介的力量,大千世界中的新鲜事物看似触手可及,但实则相去甚远。具体来看,人们在接收更多由新鲜事物发出的信号时,都要通过极其类似的方式来实现。例如,人们在大多数的工作时间中,都是通过不停地敲击键盘来达到各自的目的;又如,人们在下班后的时间里,无论是看电影、新闻或与朋友聊天,大多都是通过电脑、手机等电子设备来实现。这都使本该不断以不同形式涌现的新鲜事物被固化到了一成不变的电子设备之上,人们获得新鲜感的方式相对固定,新鲜感的获得度大为降低,无聊之感便随之而生。

  坦白地讲,长此以往的话,当下人们身边的很多事物,只会让人们的生活变得愈发无聊。因此,如果你也总感到无聊的话,不妨尝试放下手机或关掉电脑,减少旧有媒介的使用时间及频率,反之借助其他媒介、向着新的方向迈出不同于以往的步伐。

    也许,生活的真彩就在那灯火阑珊处。
