长期大量喝茶对身体有什么副作用？！这个问题看似在引诱和误导人们来批评茶对人体的害处，实际上是提问者想让人们反向思维，从生活中，工作中，文化传播中来肯定茶的优秀品质和茶对人的有益健康作用。如果饮茶过量,时间一长,就可能出现上述氟中毒的现象。有人报告,四川省壤塘县居民因长期饮用含氟量高的砖茶引起了慢性氟中毒。这里的居民有个习惯,食用主食青稞时,必以煎煮的茶水拌食,这种茶水含氟量很高,
热水里的嘌呤含量很高，如果只是长期喝茶，对人身体没什么影响。因为茶叶曾经在欧洲中世纪的时候，做过活体实验！让囚犯饮茶，最后都是活到了80多岁，并且没有任何并发症。如果长期喝酒的人，由于大量喝茶，特别是大量喝浓茶，很容易刺激胃肠道。有时候在浓茶基础上加上一些刺激性食物，如辣椒、酒精等双重作用下可能会导致胃部痉挛，甚至是出现疼痛性休克，所以平时喝茶的时候尽量不要喝太浓的茶。
茶是大自然赐予人类的珍贵礼物，几千年来一直影响着华夏子孙，从上古时期，“神农尝百草，日遇七十二毒，得荼而解之。”我们的祖先神农氏发现茶迄今大约6000年历史，经历几千年的轮回仍然能流传下来，喝茶是一种历史悠久的生活习惯，所以也很讲究，不同地方文化不一样，不同茶讲究不一样，副作用也不同，对人体不同体质喝副作用不一1样，比如绿茶，热茶，凉茶，红黑茶都要给自己体质需求而喝，所以佛家有人讲禅茶合一。
长时间大量喝茶必然会给肾带来负担，且过度摄入咖啡碱还会伤害肾脏的正常功能。因为茶中含有碱性茶碱，在饭后进入体内容易稀释胃液，抑制胃酸，阻碍胃酸蛋白酶的形成，进而提高出现肾结石的机会。
茶叶含有茶碱、咖啡因，如果喝多了可以使人长期处于兴奋状态。虽然可以起到提神作用，但是也可以引起失眠、心慌、头疼、眼花、耳鸣的症状。尤其是过多饮用浓茶，症状会更严重。茶叶中还含有草酸，可以引起泌尿系统结石。
喝茶水过量会影响人体对食物中铁的吸收，可能会引起贫血等症状，而且茶汤中的含氟较多，茶喝多了特别容易导致牙黄，会让牙齿特别的脏，而且还可能引起骨质疏松，导致骨骼疼痛，并且茶水中有一些咖啡因，喝多了对神经非常的刺激，尤其是晚上喝多，不仅会加重肝脏的负担，而且还会兴奋的睡不着觉。
可能会导致自己的牙齿变黄，而且骨骼也会非常的疼痛，可能会导致失眠，让自己的肾脏负担加重了，而且会阻止铁的吸收，可能会患有贫血，还有可能引起一些肠胃系统的疾病。
会对我们的心脏以及肾功能都造成一定的影响，而且对我们的肠胃也非常的不好，很容易造成严重的疾病，同时会对我们的血液也造成一定的影响。
