We all know drinking enough water every day is super important. But why?
Water is a critical component of all our organs, tissues, and cells. While different parts of the body require different amounts of water, every part of the body needs water to function.
Problem is, water doesn't stay in the body. It's lost through processes like breathing, moving, and going to the bathroom, so it's crucial to replenish your fluids.
But what happens when you don't get the water you want and need?
Without water, your blood can't deliver oxygen to your body or brain. After a while, this leads to fatigue and a depressed mood.
Muscles don't like being dehydrated, either.
It doesn't just end with a little bit of crankiness and a couple cramps, though. Over time, dehydration can interfere with your body's ability to digest food and get rid of waste, leading to weight gain and premature aging.
A human can survive about three days without water, but some horrible effects occur before you actually die, so it's best not to even push it.
That said, it is possible to get TOO MUCH water...
Check out this cool video by TED-Ed's Mia Nacamulli on why we need to drink water — but why we shouldn't overdo it either.
