I am one person who drinks very little water and yet, visits the loo most often.
I understand that water is the element of the Sacral Chakra, which is related to emotions, creativity, knowledge, attention, and sexuality.
In Sanskrit, this chakra is called Swadhisthana or ‘one’s own abode/ home’. It holds our sensing/ feeling energy. It connects us to our fellow human beings through feelings, intimacy, sensations, and desires. It regulates our joy factor.
When this chakra is in the ‘cleansing mode’ the resultant toxins are expelled through urine, tears and sweat. (My Swadhisthana is usually in cleansing mode.)
Similarly, when the Root Chakra (The Muladhara/ the main foundation), whose element is Earth, is in the cleansing mode, the toxins are expelled through loose motions. Muladhara is related to our survival instincts, ability to stand up for ourselves, and security. (Of late, my Muladhara too is in the cleansing mode.)
Manipura (solar plexus) does so through vomiting, Anahata (heart chakra) through gas/ bleeding, Vishuddhi (throat chakra) through cough/cold/ phlegm (My Vishuddhi Chakra too is perpetually in the cleansing mode.)
Well, this is a very simplistic explanation; and more often than not, more than one chakra is in the cleansing mode (cleansing being a regular/ normal/ natural process).
