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.
How many ounces can your bladder hold? The bladder serves as a holding area for urine and is located in the pelvic region of the body. Urine is produced in the kidneys and then travels through the ureters to the bladder. Spokane Urology reports that urine continually builds in the bladder until it is emptied. Nerves within the bladder send signals to the brain when it has reached its limit, which causes the urge to urinate.
