Question

why we get urine more in winter

Answer 1

A normal human urinates more in winter because during winters a human doesn't needs much water to keep him cold which happens because of sweating during summers instead water is only used to remove impurities from the body during winter so the extra water comes out.
So, during summers a human urinates less while during winters a human urinates more just to keep the body temperature low (during summers).
