Gatorade Created a New Wearable Patch That Tells If You’re Hydrated Enough

Gatorade has teamed up with a tech company to create a wearable patch that tells you if you’re hydrated enough.

All you have to do is apply the Gx Sweat Patch on your inner left arm while you’re working out.

And then, it beams your hydration — or sweat — info to a smartphone app that lets you know how much to drink to get your hydration levels back to normal.

Of course, whether you choose to hydrate with Gatorade or water is up to you.
