1.13K views

if i am awake and drinking like I usually do i’ll pee extremely frequently and the accumulation of that fluid is never apparent when looking at me but when i wake up i have so much stuff to pee out that accumulated at the bladder that i look like I’ve just found out i’m pregnant why is it that if i tried to hold it in when i was awake i’d be in a great deal of discomfort but i don’t wake up in discomfort but am visibly swollen with fluid

There is a centre in the brain that regulates sleep. Part of what it does is inhibit certain motor functions, and part of what it does is to inhibit certain sensory functions. Some of the things it inhibits are hunger, thirst, pain, and (of course) bladder sensors.

Now, obviously, the sensory inputs do not get inhibited completely.
