If you stop to think about it, there aren't many things that are one-size-fits-all, especially when it comes to our health. And that goes for water consumption, too. Sure, the Institute of Medicine gives women a general guideline of drinking about nine cups per day, and everyone's been trying for years to follow the "eight cups a day" rule because it's easy to remember eight ounces, eight times. But those are just general guidelines. What you actually need varies all the time based on your workout routine, sleep habits, where you live, how much you weigh, and more.
With the high-tech inventions people are coming up with on the reg, it was only a matter of time before water bottles started veering away from general guidelines and got a smidge more specific. Enter the new Pryme Vessyl, an "intelligent" cup developed by former Apple and NIKE/Jordan designers. What makes it so smart? It takes into account a variety of unique-to-you factors to not only encourage you to drink more, but it figures out exactly how much more you really need. (Here's why it's so important for you to stay hydrated.)
After you download the bottle's corresponding app, you'll enter data like your birth date, height, age, weight, sex, and sleep and exercise habits (you can also sync up your Apple Health and Jawbone UP apps to shoot this info over faster). Then the bottle automatically tracks your water consumption, and incorporates it into the company's hydration algorithm to keep you updated on what you need to do to reach (or stay at) your optimal hydration—or your "Pryme." You can get those updates right on your bottle, which lights up with lines that rise and fall based on your current needs. Or you can have little reminders like,"Just a few more sips and you'll reach your Pryme" sent to your Apple Watch, while more in-depth progress reports are housed in the app.
Of course, given that the bottle has some fancy built-in technology, the next question is obvious: How much does it cost? At $99, Pryme is definitely an investment. But if the above hasn't convinced you, perhaps its extra bonus features—a spill-resistant 16 oz. bottle that offers up wirefree charging that lasts up to two days per charge—will. Regardless, it's time to drink up.
