This is the super-simple way to figure out how much water you should drink every day

If you’re anything like me, you have at least three water bottles littered around your apartment, office, or workspace. But for all the guzzling that I do, you’d think I’d keep track of how much I was drinking—and if I was meeting my daily intake of how many ounces to drink every day. But nah, not so much.

Turns out there is a magic number, and you can figure out *exactly* how much water you should drink every day. All you need to do is split your bodyweight in half and drink that many ounces, according to Parsley Health nutritionist Adrienne Dowd. So if you weigh 150 pounds, that’s 75 ounces of water you should be drinking every 24 hours. Pretty easy, right?

“Drink half your bodyweight in ounces of water each day.”

Know who else are fans of this brilliant hydration hack? Tone It Up founders Karena Dawn and Katrina Scott. The fitness boss babes swear by this method, too, having posted about it on Instagram earlier this year, captioning the photo: “Can you guess the magical thing that helps you recover post-workout, feel energized, boost your mood, and make your skin glow?! Hint: It’s clear! Yup, water…drink half your bodyweight in ounces of water each day!…We promise you’ll feel amazing!!”

BRB, while I go refill my water bottle.

Take your newfound H2O knowledge and make sure to always hydrate with some water in the morning, and note that it can help prevent a slew of conditions, including UTIs.
