Quick answer: A little, probably. There is no strong scientific evidence that straws make people drink more water, but the convenience effect is real: a straw makes sipping easier, spill free, and nearly automatic, and small conveniences are exactly how drinking habits form. If a straw gets you to sip more often, it is doing its job. Just know that keeping water within reach and making it taste good matter more than the straw itself.
Do straws actually help you drink more water?
Honest answer: nobody has run a rigorous trial on this, so the strongest claim we can make is a modest one. What we do have is a very consistent pile of anecdotes, ours included. Around the Epic office, the bottles with straw lids empty faster than the ones without, and plenty of runners, dietitians, and hydration obsessives report the same thing.
The likely explanation is not magic. It is friction, or rather the lack of it.
Why a straw can help
It removes tiny bits of friction
No unscrewing a lid, no tipping a bottle back, no dribbling water down your shirt on a video call. You can sip while typing, reading, or driving. Habits live and die on details this small.
Sipping becomes automatic
When the straw is right there, sips happen without a decision. That is the quiet superpower: dozens of thoughtless little sips add up to a surprisingly empty bottle by mid afternoon.
The smoothie test
Think about how easily a smoothie disappears through a straw. Same mouth, same physics, and water is the one drink you can down this way completely guilt free.
What matters more than the straw
Keep water within arm's reach
The single best predictor of how much water you drink is whether it is sitting next to you. A bottle on your desk beats a glass in the kitchen every time.
Make it taste good
If your tap water tastes like chlorine, no straw will save it. Filter it, chill it if you like it cold, or add a squeeze of lemon. You drink more of what you enjoy.
Anchor it to a routine
A glass when you wake up, a refill before each meeting, a top up at lunch. Attaching water to things you already do works better than willpower.
Any downsides to drinking through a straw?
For water, not really. A few people swallow extra air and feel bloated, reusable straws need honest cleaning, and that is about it. Straws are actually the dentist approved way to drink acidic beverages, though plain water is kind to your teeth either way.
The bottom line
A straw is a cheap, harmless nudge that makes drinking water slightly easier, and slightly easier is often all a habit needs. Try a week with one and a week without and see which bottle runs dry faster.
If you want the straw and better tasting water in one move, the Epic filtered bottle pairs a straw lid with a filter, so every sip is filtered on the way up. Prefer sipping from a glass? Keep a Pure XP pitcher on the counter, or browse the full pitcher lineup and fill whatever vessel makes you happiest.
