The great benefits of pouring one full litre of water or more over the genitals during and after urination.
Pouring large amounts of cold water over the pubic region creates an exchange of blood in that area which bring freshness to both body and mind. That circulation of blood nourishes all the glands, organs, nerves and cells of that region.
The muscles, nerves and overall biological system get strengthened by the use of adequate amounts (1 litre or more) of cold water.
It will prevent and eliminate bladder problems faced by older people who cannot control the flow of urine during the night time. That happens because the muscles and nerves weaken over time, but when cold water is regularly used then those bodily systems remain strong and intact, in which case one will not suffer from that problem in old age.
One other great benefit is that it will ensure that all excess urine is removed from the urinary tract, as well as from the bladder. This keeps the body clean and disease free.
Bladder Stones: When excess urine remains in the bladder then there is the possibility for that to crystallise and form stones that can completely block the urinary tract. By pouring sufficient cold water after urination, then all the urine is released from the body and there is no possibility for the formation of bladder stones. If due to some disease the urine remains in the urinary tract then one is prone to stones. And the root cause or main problem is that one not emptying their bladder regularly. So bladder stones are 100% preventable. The process of pour water slowly ensures the bladder is empty.
After years of not getting adequate nourishment, those muscles and nerves become weak. That is why when people reach 60 years of age, many lose control over the flow of their urine. On an involuntary basis, urine just releases. That is why older people have to use pads or diapers in their undergarments - because anytime in any 24 hr period they may suffer from incontinence. They have an ongoing drip. It is unfortunate that many have to face this humiliation when it is so preventable by using an adequate amount of water.
''This is not an eventuality or function of age''; it is a only a function of poor life practices. If one slowly pours an adequate amount of water over the entire pubis region, then those nerves and muscles will remain strong even into very late age. Then one will have proper control over the flow or urine.

It is your choice whether you want to use water,try it what can you loose?
