下面是心理咨询师与求助者的一段对话：
求助者：您看我的气色怎么样
心理咨询师：您的气色看起来挺不错的。
求助者：是吗你不觉得我脸色蜡黄吗
心理咨询师：没有啊。
求助者：可是我肠胃不好。我看书上说消化系统有毛病的人会面黄肌瘦。而且最近我总是心烦气躁的，您没发现我有什么不正常吗
心理咨询师：没有啊，都很正常啊。
求助者：哎，您一定是在安慰我。半年前我的胃就开始疼，我怀疑自己得了胃癌。我爸爸就是死于胃癌的，我也有遗传基因的。
心理咨询师：那你到医院检查过吗你说的这些医生都知道吗
求助者：去医院检查了，该做的都做了，大夫说是胃炎，开了点药，可是一点效果也没有。后来我又多次做检查，一直折腾到了现在，钱是花了不少，可是就是没有个明确的诊断结果。我怕是胃癌早期查检不出来，把病给耽误啦。最近半个月，我开始失眠，也不想吃东西，白天上班也没精神，往那一坐就心烦，最后搞得我只好辞职。
心理咨询师：那你的这种情况和医生说过吗
求助者：说过，可医生说我瞎担心，根本就不是。而且还建议我看看心理医生，我就来了。

A．强迫

B．焦虑

Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain Cases, harmful.

In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pennsylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins (毒素) better, improves skin, and helps reduce weight.

Dr Goldfarb and Dr Negoianu say that they found little proof to support the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they found little proof of harm in drinking 8 glasses of water every day.

It is widely believed that in some cases — such as athletes, people who live in hot, dry  environments, and those with certain medical conditions — drinking a lot of water indeed helps,  but no studies have been done to prove the benefits of this practice in average, healthy people, the  website medheadlines. com reports.

The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, “but the difference in the number of headaches was so small between the two groups as to be considered unimportant.”

The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each day.

The website medheadlines. com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur.
