Answer 1

The kidneys don’t work ‘harder’ with more water, they work ‘smoother’. A bit like more (clean) oil makes a car engine run smoother.

The kidneys function is to filter out waste in our blood. They do this whether or not we are sufficiently hydrated.

Imagine kidneys as a kitchen sieve and you pour some thick curry over them, sure the bits will filter through eventually but it will be slow. Add a lot of water over the curry and the bits will be filtered out much much faster.

**Please note that ‘more’ water does not mean excessive water!
