Eli5 what in water Makes it necessary for humans to need it?
In: Biology
It’s not really what’s in water. It’s how much water is in us, for us to function. Without it, the body, which is slowly losing water all the time due to environmental- and activity-based water loss, will slowly cease to function. It’s in your saliva, helps move waste out of your body, helps regulate temperature (via perspiration), etc. Without sufficient hydration, almost nothing in the human body functions correctly.
