We are less anxious when we are thirsty a new study

Response to social anxiety better when our sodium levels are elevated and we are thirsty. The reason for this according the the article is that we have to search for water so we are less likely to be anxious.  Eric Krause, PhD from University of Cincinnati is quoted saying:

"When you're thirsty, you have to overcome some amount of fear and anxiety to approach a communal water source. And you want to facilitate those interactions - that way everyone can get to the water source."

Krause and his team dehydrated laboratory rats by giving them sodium chloride, then exposed them to stress. Compared with a control group, the rats that received the sodium chloride secreted fewer stress hormones and also displayed a reduced cardiovascular response to stress.
