A 2004 study also found medical residents with less than four hours of sleep a night made more than twice as many errors as residents who slept for more than seven hours a night, an especially alarming trend given that less than 11% of surveyed residents were sleeping more than seven hours a night.
Best Answer: A normal adult bladder can hold anywhere from 16 to 24 ounces (about 500 to 750 mL) before the urge to urinate becomes overwhelming. Everyone's bladder is different though, so some can hold more than that amount, some less.
I was told that my bladder will hold 500cc's and that the average is 1000cc's. The normal female bladder holds about 500 or so cc's awake. Under anesthesia, a normal female bladder capacity is about 800-1000cc. I'm assuming it holds about 500 cc's when you feel like you absolutely cannot hold it any longer.
