Stay Hydrated and Improve Your Mood—This Smart Cup Can Help

A thin light on the side conveys how well you are meeting your personal hydration needs…

Can being well hydrated improve one’s mood? Sharpen mental machinations? The researchers behind the new Pryme Vessyl cup ($99) think so. “Mood balance, cognitive performance, attention, focus—all are dramatically impacted by your hydration,” says Hanson Lenyoun, MD, a Harvard University graduate and Columbia-trained physician who helped develop the 16-ounce glass-lined cup, which logs how much fluid a person imbibes throughout the day. The cup syncs up with a smartphone app that collects details about one’s age, weight, and activity, then feeds it through an algorithm to gauge a user’s unique, fluctuating hydration needs. A thin light display on the cup’s side conveys how well the user is meeting his or her hydration needs on a scale of zero to 100. When levels are low, users are encouraged to take a bigger sip. “Just a one percent change in hydration status can affect your cognitive abilities and focus,” says Dr. Lenyoun. The cup can be recharged on its wireless charging coaster. »prymevessyl.com
