This isn't a write-up of an iPhone-only app, or a push to go out any buy some battery-powered uni-tasker. This is simply an easy and free health tech tip that a fitness-minded friend passed along.
Lately, our water intake has been more like a binge-and-purge. After a busy workday—where we barely remembered to eat lunch let alone drink 8-10 glasses of water—we'll guzzle down several make-up glasses at the end of the night. But the benefits of drinking enough water are best enjoyed if you space your water intake throughout the day.
That's why we suggest you take a few minutes to set a hydration nudge on your cell phone. It's the perfect use of your bring-everywhere technology. Since you carry your phone around with you everywhere, it'll serve as a sort of personal nutrition assistant (No Siri necessary). Just use your cell's built-in alarm and set several alerts, spaced an hour or two apart, that remind you to guzzle down a small glass of H2O.
