How can anxiety cause excessive thirst? Well, this is a very complex answer. Reality is that there isn't a single cause. There are a whole host of different reasons why anxiety may contribute to feel thirsty. Here there are some:
Dry Mouth – Anxiety 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/Dehydration – Of 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 thirst.
Excessive Urination/Sweating – During periods of anxiety and anxiety attacks, many people sweat and/or urinate. These are natural reactions to anxiety. These also cause water loss, and may cause you to need more water during the day than you used to.
Mouth Breathing – Anxiety and anxiety attacks also cause a great deal of mouth breathing, often in an attempt to get more air. Mouth breathing naturally dries out the tongue, which – like dry mouth – may give the impression that you need to drink more water, even though you don't necessarily need that water.
Water Baseline – It's also possible that you feel more thirsty because you quenched your thirst in the past during anxiety. If you started drinking a great deal of water to compensate for the thirst you felt from your anxiety, your body may adjust and turn that water into your new hydration baseline. Now you may actually need more water than you used to, simply because your body thinks it will be providing it.
Perceived Dehydration and Hypochondria – Finally, one reason that many people dislike is the idea that it's all in their head, but unfortunately this is a very common problem for those with anxiety. 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 undoubtedly become thirstier.
There is unlikely to be a specific, obvious cause to this feeling of dehydration. Chances are it's a combination of several of these factors. Although, one thing is for sure: Marco Rubio suffers a perennial state of anxiety that leads him to drink tons of water all day long.
What's the cause for Rubio's perennial anxiety? Probably it's a performance anxiety that comes from an identity problem: He's got a cuban name but he cannot connect to the Latino voters. Why? because he probably refuses to acknowledge where he comes from. His grandfather illegally entered the United States and probably such an event traumatized the little Rubio since he was a kid maybe because his parents were ashamed of such an immoral/illegal behavior.
A people's representative who refuses to acknowledge his own origins is really in a state of great distress and suffering.
Being a Latino but refusing to identify and to connect with his own community creates a great state of anxiety, that's why he drinks a lot of water. Maybe Marco Rubio would love to work as a Republican candidate for the wasp side of the party but the GOPs have a desperate need to connect to their Latino audience so they are asking Rubio to connect to his natural audience.
Rubio feels these Latino shoes are too tight for him, he doesn't feel at ease with his origins because his thoughts immediately go back to the misery of his grand-father, and the shame his family felt when he was deported because he was an illegal immigrant.
Maybe Politics is too stressful for Marco Rubio, because it forces a man to get in touch with his past, his family history and if you did not clarify with yourself who you are and where you come from, you re going to drink a lot of water....
