I've had a problem for as long as I can remember that on most mornings, I have to wake up a little earlier because of an urge to urinate. Sometimes it's quite a small volume of urine, but I still have the urge. I still haven't figured out exactly why this happens. Obviously things like caffeine and drinking later at night play a factor, but I haven't noticed a dramatic change after stopping both.
Recently, I've discovered that if I increase my salt intake, I usually don't have this problem. I usually realize after waking up that I had something salty for dinner like instant ramen noodles (very high in sodium) or a salty dish.
Does anyone know why this happens? It seems contradictory to the fact that you can't drink sea water because you will get dehydrated. I don't know if that dehydration is due to peeing or water coming out of our body's cells. Does anybody know?
Could it be that my salt intake is lower than it should be? I have a pretty healthy version of the American diet and I eat from all the food groups. I would find it hard to believe that my salt intake is low, given the fact that most health guidelines advise Americans to lower their salt intake.
I'm thinking another possibility could be that my salt intake is fine, but increasing it helps mask this "need to pee" problem I have.
