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.
You can say that the average male bladder capacity is around 400-600ml, or 13-20 fluid ounces. This would be the volume voided after holding urine to the point of severe urgency. If the patient is under anesthesia and the bladder distended with water, the bladder can usually hold even more, around 1000ml or 33 fl. Oz. In brief: Varies; 400-600mL. There is, of course, a wide range. You can say that the average male bladder capacity is around 400-600ml, or 13-20 fluid ounces.
