So I guess once the urine color is clear and not yellow, you are not longer to need force yourself to drink more water?
It is some kind of indicator that your body don't need more water or just some urban myth?
normal colour of urine is pale yellow.It is some kind of indicator that your body don't need more water or just some urban myth?
basically, urine is excess water, salts and minerals, as well as urea from protein digestion, uric acid, creatinine from muscle breakdown, hormone waste and toxins. Also eliminated is urochrome, which is a yellow pigment that comes from the processing of dead blood cells in the liver.
the colour of urine indicates the concentration of waste product in urine. the darker the colour the higher the concentration of waste product in it.
