I prefer to take showers; however, a bath or a firm and heavy sprinkling are both very therapeutic and rejuvenating to the overall well-being and to the senses.
I cannot at all understand people who do not like to wash themselves on a regular basis, those types of individuals who can go for weeks to months without a proper rinse or soak. To me, that kind of behavior is indeed a form of mental illness aside from utter/sheer nastiness.
A thorough wash produces the mind and body with good stimulation and a fresh invigoration even enabling one to get a better nights rest and relaxation.
One just feels better altogether.
When the body is dehydrated water is one of the best internal liquid solutions as the sugars within juices sometimes initiate further thirst. Water cleanses and keeps the kidneys healthy as well as flush out the other toxins and impurities that enter then travel within.
The essential and beneficial is just as vital as the oxygen that we all breathe, water is life sustaining and we cannot live or do without it in any way possible, and I would not want to.
