Thirst may not seem like something related to your anxiety, but it's something that many anxiety sufferers deal with regularly. There is often this feeling of needing to drink a glass of water or two during and after anxiety attacks, and some people feel as though they need to drink more water each and every day.

Anxiety and thirst have a very complicated relationship. We'll explore this relationship below.

Drinking Water for Anxiety

有可能喝太多的水。它被称为水中毒，这是一个令人难以置信的罕见现象，通常在婴儿和运动员之间观察到。水中毒所需的估计水量约为4加仑，通常（虽然并非总是总是）这只发生在你喝太快的水时 - 不是在整整一天蔓延的时候。

So if you're feeling thirsty, it's probably a good idea to drink some water. There's no reason not to try to quench that thirst unless you've already had too much.

Excessive Thirst and Anxiety: The Cause

The first question that people ask is: how can anxiety cause excessive thirst? The reality is that there isn't a single cause. There are a whole host of different reasons that anxiety may contribute to a feeling of needing more water. Some of these include:

• Dry MouthAnxiety does have a tendency to cause dry mouth, and dry mouth can feel like thirst. Anxiety may cause dry mouth by taking water away from your mouth and sending it to the areas of your body that need it, or by increasing acids in your stomach that may contribute to a loss of saliva. Anxiety can also cause you to feel sick, which may also lead to conditions that feel like dry mouth. All of these can make you feel like you're thirsty when you're not.
• Not Drinking Water/DehydrationOf course, one of the simplest explanations is that you're not drinking enough water. Anxiety has a tendency to make people feel full when they're not, or to cause a loss in appetite. Many people with anxiety do not drink enough water, and that "excessive thirst" is really just an indication of dehydration.
• Excessive Urination/SweatingDuring periods of anxiety and anxiety attacks, many people sweat and/or urinate more frequently. These are natural reactions to anxiety. These also cause water loss, and may cause you to need more water during the day than you’re used to.
• Mouth Breathing焦虑和焦虑的发作也造成大量的嘴巴呼吸，通常是为了获得更多的空气。嘴呼吸自然地干涸舌头，如干口 - 可能给人一种印象，即使你不一定需要那种水，你需要更多的水。
• Perceived Dehydration and HypochondriaIt’s fairly common for people with anxiety to simply imagine that they’re dehydrated, even if this isn’t necessarily the case. For some people, this can develop into an excessive and distressing concern. Many people read about how they may not be getting enough water, and anxiety causes them to start thinking about their thirst. Once you think about your thirst, you'll often become thirstier as a result .

Drinking Water is Still a Good Idea

脱水都可以引起焦虑症状本身，并在未经处理的情况下使焦虑症状更差。只要你没有过度水合，就不一定在饮用水中造成任何伤害，以减少症状。有些人发现喝凉水的行为镇静，而且许多人在焦虑症中喝水，即使在没有任何过度的口渴时也能使他们平静下来。

Keep a Cool Head

However, you will also need to make sure that you don't try to talk yourself into believing that something is wrong because you need more water. Thinking about how much water you drink can actually make you more thirsty. When your mind is focused on how thirsty you think you'll feel, you're likely to need to drink more water as a result.

Don't forget that all of these issues are caused by anxiety, and so the only true way to treat it is to accept that anxiety causes you to feel this way and commit to curing your underlying anxiety.
