Eg some Chinese cultures would park urn into a temple for life where monks become a caretaker . They do pay a lot of premium to park it there . <| sep |> That ' s not very nice . <| sep |> Close enough to this as CAPCOM could get LSUxpDLkMM <| sep |> From what I ' ve been able to find to answer your question OP , it seems like it ' s a matter of your brain and your bladder maturing and learning to communicate better . Most adults simply don ' t need to urinate at night , or they can hold their bladder until morning . if an adult needs to pee at night , their bladder sends a signal through the nervous system to the brain , and they will usually feel the need to get out of bed and relieve themselves or the brain will tell the bladder not to release itself until the person is ready to get up . Children don ' t begin to get this signal until around midchildhood . It could also be because of a hormone called Antidiuretic Hormone ADH . In bed wetters , the amount of ADH produced in the evening time is found to be lower . It ' s a chemical that signals to your kidneys how much water to retain . If the amounts in your bloodstream are too low , you ' re body will produce to much urine at night . Children and adults ! who don ' t produce enough ADH may end up wetting the bed , especially if they ' re deep sleepers . It ' s more or less bladder control , and your brain and bladder communicating more clearly with each other . Children just don ' t have the same signals and cues as adults do . Some outside factors can cause it , including UTI ' s , injury , constipation , diabetes , and stress . Hope this helps ! Sorry if it ' s a bit confusing ! But it ' s not one single thing that causes bedwetting in children or adults . Not all children wet the bed , and it can even sometimes be caused by genetics if the child has parents or close relatives who also wet the bed at their age . The problem usually goes away on its own as the child gets older , and their bladders expand and their brain begins sending the right signals . Edit TLDR Children usually wet the bed due to a variety of factors that can include stress , hormone production , illness , bladder control , and genetics but mostly it ' s because adults get signals to their brain from their bladder and the brain will simply wake the person to urinate , or tell the bladder not to release itself until the person gets up . Children don ' t get the same signals , and have smaller bladders , and therefore do not wake up just because they need to go , or they might simply be deep sleepers and when the bladder becomes too full they simply just don ' t wake up . Some people don ' t produce enough of a chemical that causes the production of urine to slow at night , and combine that with a child ' s small bladder and poor bladder control , and viola , bedwetting can happen . Children usually begin to receive the signal around midchildhood 911 years old , and most children will grow out of bedwetting simply with age .
