长时间上网或者玩电脑的害处

长时间上网或者玩电脑的害处 危害 一、危害青少年的身心健康 网络成瘾者因为对互联网产生过度依赖而花费大量时间上网。青少年正处于身体发育的关键阶段，沉迷于网络世界，长时间连续上网，新陈代谢、正常生物钟遭到了严重的破坏，身体容易变得非常虚弱。还有研究表明，青少年长期沉溺于网络中，不仅会影响头脑发育，还会导致神经紊乱、激素水平失衡、免疫功能下降，引发紧张性头疼，甚至导致死亡。同时，不良的上网环境也会损害青少年的身体健康，而网吧大多环境恶劣、空气浑浊、声音嘈杂，青少年在这种环境的网吧内上网，也容易被传染上疾病。网络成瘾对青少年健全心理的发展也是一个严峻的挑战。长期上网会引发青少年“网络孤独症”和“忧郁症”等心理疾病，过分关注人机对话，对外界刺激缺乏相应的情感反应，对亲友冷淡，对周围事物失去兴趣，严重时对一切都漠不关心，把与别人的交往当成一种可有可无的事情，变得越来越孤僻，造成青少年个性的缺陷;网络成瘾者一旦停止上网便会产生上网的强烈渴望，难以控制对上网的需要或冲动.这种冲动使其在从事别的活动，工作、学习时注意力不集中、不持久，造成青少年心理的错位和行动失调;网络成瘾者过度沉溺于网络中的虚拟角色，容易迷失自我，将网络上的规则带到现实生活中，造成青少年自我认识的障碍。 二、导致青少年学习成绩的下降 青少年沉溺于互联网带来了大量教育上的问题，染上网瘾的青少年，被网络挤占了原本属于读书和思考的时间，导致的直接的后果就是学习成绩的下降。同时，国外也有研究表明，长期上网，沉湎于网络游戏的application; infection and antibacterial drug of clinical application; transfusion refers to levy; nutrition support of adapted card and clinical application; common life support technology (as cycle breathing support, and nutrition support,) and emergency technology of application; common guardianship instrument using.
