How can humans sleep 8-10 hours without urinating themselves but can only go 30min-2hours when awake without having to urinate?

Most body processes slow down when you’re asleep, brain activity, most muscle movement, digestion etc, that’s the whole point we need sleep after all, to give these systems a rest. So theres less waste products produced, so less urine.
Your brain releases a hormone called ADH (anti-diuretic hormone). This hormone affects the kidneys, especially when sleeping. ADH causes your kidneys to reduce the amount of fluid they pull from the blood. Less fluid filtered out by the kidneys means that less urine is produced.
30-2hrs ? Sir you might wana check up with a doc
You generally don’t drink while sleeping. Your body also slows down production of urine. If you drank a lot before going to sleep, you are likely to wake up early because you need to go (or accept the mishap).
You may have some sort of urinary retention problem while you’re awake. You should see a doctor
