7 Weird Things Your Body Does When You're Dehydrated (And No, Thirst Isn't Always One Of Them)

The thing is, your body is basically screaming at you when it's parched, it's just screaming in the weirdest ways possible. Forget just feeling thirsty (because lol, your body's weird like that and sometimes doesn't even tell you). Let's talk about the absolutely UNHINGED things your body starts doing when you're not hydrating properly.

Your Brain Literally Shrinks (Just A Little, But Still)
Okay so your brain is like 75% water, which means when you're dehydrated, it's basically losing its structural integrity like a sad balloon at a party. Your brain actually pulls away from your skull a tiny bit, which can cause headaches that make you want to quit your job and move to the mountains. No wonder you can't focus on literally anything!

Your Pee Becomes The Spookiest Color In The Crayon Box
Forget golden yellow, when you're dehydrated, your urine starts looking like it came straight from a haunted house. Dark amber, murky brown, basically giving "swamp water" realness.
