Your saliva?!
Question:
Your saliva?
i've always wondered... when i was thirsty and desperate, i've tried drinking my own saliva. this however (=P) was veeery ineffective. why? why can't i also spit til i've filled half a cup and then quench my thirst? is it something as simple as not enough saliva?
Answers:
Well if you were in a desperate situation and becoming dehydrated it would not help any. The saliva is fluid you already have so swallowing it wouldn't add any. But if you were dehydrated your mouth probably wouldn't produce much saliva because it would ration it for more important functions for blood and organs.
