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.
Urine drains from your kidneys to your bladder through tubes called ureters. Your bladder is the hollow muscular organ that stores your urine. It's a bit like a floppy balloon â as your bladder fills, it expands to store the urine. On average, your bladder can hold 400 to 600ml of urine for up to about five hours. The muscle in your bladder wall is called the detrusor muscle. The detrusor muscle relaxes to allow your bladder to fill. When you go to the toilet, it contracts to squeeze out urine. MOST POPULAR.
