Without water, your body would halt working appropriately. Water makes up more than half of your body weight, and an individual can't survive for more than some days without it. A straightforward way to form beyond any doubt you’re remaining legitimately hydrated is to check your urine. In case your pee is more often than not colourless or light yellow, you're most likely well hydrated. Dim yellow or amber-coloured urine can be a sign of lack of hydration.
