病情分析：
水就是最好的“清洗剂”。人们都知道早晨喝水对身体有好处，但是很少有人了解早上起床喝以下几种水是会损害健康的。
很多人喜欢早上起来喝一杯冰水特别是夏天的时候，其实这是很不科学的。喝冰水容易引起胃黏膜血管收缩，影响消化、刺激胃肠，使胃肠的蠕动加快，甚至引起肠痉挛，导致腹疼、腹泻。正常人喝冰水，尤其是带甜味的饮料，在空腹的情况下饮用后，容易引发胃病
指导意见：
早上起来的第一杯水最好不要喝市售的果汁、可乐、汽水、咖啡、牛奶等饮料。汽水和可乐等碳酸饮料中大都含有柠檬酸，在代谢过程中会加速钙的排泄，降低血液中钙的含量，长期饮用会导致缺钙。而另一些饮料有利于排尿作用，清晨饮用非但不能有效补充机体缺少的水分，还会增加集体对水分的要求，反而造成体内缺水
早晨是人体血压升高的第一个高峰，喝盐开水会使血压更高，危害健康。
