The Psychology of Hydration
Why a Light Works.
Nearly 1 in 3 U.S. adults is inadequately hydrated¹, and the problem isn't laziness. It's that a fundamental step of the habit loop is broken. AquaPuck closes that gap.
Your Hydration Cues
The Science
Why a Cue Beats Willpower
Habits start with a cue, not with motivation. AquaPuck's LED ring changes your surroundings so that drinking water becomes the default.
Every habit is initiated by a cue, and we are more likely to notice cues that stand out. Unfortunately, the environments where we live and work often make it easy not to do certain actions because there is no obvious cue to trigger the behavior.
James Clear, Atomic Habits
The LED ring sits on your bottle, not on your phone. The reminder and the action happen in the same place, which fits what habit research suggests works best.

AquaPuck started when Shreyas discovered that his chronic dehydration was causing him bloody noses and migraines. So, he decided to create the simplest way to remember to stay hydrated, using lights and notifications to remind him when necessary. After a few competition wins, testing rounds, and feedback from mentors and other entrepreneurs, the founders knew they had to bring AquaPuck to everyone else who struggles to stay hydrated.
Co-Founder
Shreyas Rao
Shreyas (class of '27) is a Colorado native, attending Kent Denver School. He started AquaPuck to fix his chronic dehydration, and then discovered the impact it could bring others. He loves skiing, hiking, and playing spikeball with friends, and has a passion for health technology that lets others stay active.
On a daily basis, he works on developing the product and the app, testing and fine-tuning so AquaPuck can release as soon as possible. He also helps make AquaPuck's marketing ads and videos along with Sohan. He is interested in where business and engineering overlap, and AquaPuck lets him work on both.
Co-Founder
Sohan De
Sohan is also in the Class of 2027 at Kent Denver School. He plays tennis and also likes being outdoors. He joined Shreyas as co-founder and runs marketing, distribution, and communications. He also helps with 3D design for the product, designing prototypes before competitions and testing rounds.
How it started
Built From a Really Bad Morning.
He wasn't lazy and he hadn't forgotten. Nothing around him ever reminded him to drink.
One morning, Shreyas woke up feeling awful. His head was pounding, his nose was bleeding, and he was dizzy before he even got out of bed. He had slept eight hours and wasn't sick. The cause turned out to be simple: he hadn't drunk enough water the day before.
That morning he started thinking about why staying hydrated is so hard, and not just for athletes. Plenty of people drink coffee all day, sit at a desk, go from class to class, and only realize they're dehydrated once their body starts hurting.
Nearly 1 in 3 U.S. adults is inadequately hydrated¹. Most of them care about their health, yet often fail to drink. This is because a fundamental step is missing from the habit cycle.
Why hydration matters
What proper hydration does
Hydration affects almost everything about how you feel. Your brain, your muscles, your body temperature, and your organs all depend on water.
01
Better focus
Even mild dehydration, a loss of about 1.5% of body weight in fluid, can hurt vigilance and working memory and increase fatigue.³
02
Steadier energy
Fatigue is one of the first signs of dehydration. Keeping up with your water helps your energy stay steady through the day.
03
Better physical performance
Losing 3% of your body's fluid can cut physical output by up to 20%. That matters whether you work out or just walk to class.
04
Better mood
Research links dehydration to higher cortisol and a worse mood. Drinking enough water is a simple way to feel calmer.
05
Long-term health
Chronic dehydration is linked to kidney stones, UTIs, digestive problems, and strain on the heart. The effects build over time.
The idea
Built on One Belief.
We started AquaPuck with one belief: hydration should become automatic. A reminder should be part of your surroundings and work in the background. AquaPuck's LED ring prompts you to pick up your bottle when you need to drink, so you don't have to remember your goals.
We wanted the product to be as small and minimalistic as possible, so users can easily integrate the fix. AquaPuck simply attaches to your current water bottle with a tiny footprint, so you'll barely notice any change.
Where we are
Pre-Launch, and Building.
AquaPuck is still pre-launch. We're in the stage of testing and developing the hardware and app, to make the user experience as easy and seamless as possible. We're a small team and we are focused on the details, wanting the product experience to feel amazing every time. When we're ready, we'll launch a Kickstarter campaign to raise funding for AquaPuck, with support from our waitlist!
We aren't trying to out-feature everything, but rather using principles-first design that focuses only on the essential elements of the habits of hydration.
What we believe
What We Believe
01Belief
Environment beats willpower
Habits form through cues, not motivation. We design the cue so you don't have to rely on discipline.
02Belief
Less is more
We say no to any feature that doesn't help you drink more water.
03Belief
Hardware matters
Software is easy to update. A physical product has to feel right from day one.
04Belief
Water is for everyone
A portion of every AquaPuck sold goes to The Water Project.
