I get it. It’s simpler to drink water when it’s loaded with taste and inside arms attain always. I assumed I used to be doing a good sufficient job, ingesting the plain stuff on the really useful 64 ounces per day.
After I was sidelined with a (large, painful) kidney stone, I began to query the place that advice got here from and the general discourse round hydration. The primary recommendation my urologist gave me was to drink extra water. Like, much more water. She really useful nearer to 4 liters, greater than double what I assumed I wanted.
How may I’ve gotten my very own hydration so mistaken?
Hydration, in line with science
The 8 x 8 rule (ingesting eight, eight-ounce glasses of water), is not actually rooted in any scientific proof, but it surely’s well-circulated recommendation. Some sources say we want extra: The U.S. Nationwide Academies of Sciences, Engineering, and Medication suggest 3.7 whole liters of water for grownup males (13 cups coming from drinks) and a couple of.7 liters for grownup girls (9 cups coming from drinks).
However some sources say we want much less: Many information shops reported on analysis printed in Science in 2022 that pointed to the concept that wholesome adults want lower than 64 ounces, implying that these of us with entry to wash ingesting water have been overhydrating. However what the examine actually highlighted was how variable water turnover is relying on plenty of components:
- Physique measurement
- Intercourse
- Local weather
- Bodily exercise
- Socioeconomic standing (pertaining to entry to meals and clear water and the kind of work you do)
- Whether or not or not an individual was pregnant or breastfeeding
“There may be a lot contradictory recommendation as a result of there is not actually a advice,” says Melanie Betz, MS, RD, a Chicago-based registered dietitian who focuses on kidney stones.
For instance, these suggestions don’t consider if you happen to’re susceptible to kidney stones, like me. (As a result of if you happen to’ve had one kidney stone, you’ve gotten a 35 to 50 % likelihood of getting one other inside 5 years.)
“For a standard, wholesome particular person with no medical historical past, I feel that the generic eight cups of water per day is a extremely good start line,” says Betz.
A few of the confusion may additionally come from what we’re measuring, similar to the quantity of water you could stave off true dehydration versus the quantity of water you could really feel your finest.
“We definitely know [dehydration],” says Betz. “You understand, your blood sodium ranges are going to go up and also you get dizzy, these forms of issues. That is outlined … However there’s not a definition of how hydrated try to be to actually really feel good.”
So, if there aren’t any true tips to hydration, how will you decide what you want?
Good hydration tech to hydrate smarter
Enter hydration trackers of their many varieties. If the quantity of water you want relies on altering components similar to bodily exercise or local weather, it is sensible that you could be want some help in calculating what your physique wants. That is very true for older adults or people who find themselves much less more likely to really feel thirsty.
My physician’s advice of 4 liters of water didn’t consider that I’m additionally an extended distance runner and that I nonetheless supposed to coach for a number of races in the summertime’s warmth and humidity. How was I going to regulate my hydration plan additional?
Enter: new hydration wearables to very particularly regulate my wants.
The 2 merchandise I examined are comparable in scope, measuring your sweat and electrolyte loss all through a session. The primary product, Nix, is a sensor you connect to your arm by way of a recyclable patch. The patch ensures your sweat is sealed off and doesn’t evaporate, in principle supplying you with a extra exact studying.
The opposite product, hDrop is a extra conventional sports activities band—a one and accomplished buy—but it surely’s attainable to see how extra sweat is more likely to evaporate.
Each Nix and hDrop have been straightforward to arrange, requiring a fast obtain of their respective apps that hook up with the units by way of Bluetooth and fast creation of an account. The hDrop app even features a tutorial on setup and the right way to interpret your information. To make use of both machine, you have to begin a exercise within the app, as they don’t run repeatedly within the background.
When your exercise is full, every app provides you an evaluation of your sweat information, together with fluid loss, electrolyte loss, and sweat composition based mostly on how a lot fluid you replenished throughout the exercise. The hDrop app was somewhat extra detailed breaking down electrolytes particularly into sodium and potassium. It additionally provides customers an in depth restoration plan with how a lot fluid and electrolytes must be replenished based mostly in your exercise.
I used to be impressed by the real-time readings from every and the customized suggestions based mostly in your sweat profile. The Nix biosensor will even provide you with notifications mid-activity when it’s time to drink up.
I discovered that I lose a mean of 1.2 liters of sweat per hour that I run, which makes me really feel extra justified in guzzling as a lot as I now do. Lastly, I didn’t should guess how a lot to drink after the run, the units instructed me, even going as far as to recommending an electrolyte product that finest matched my sweat profile.
“Hydration monitoring and sweat monitoring instruments like Nix or hDrop might be helpful, particularly for athletes or individuals who must handle hydration intently,” says Raj Dasgupta, MD, medical reviewer for the Nationwide Council on Growing older. “Nevertheless, they don’t seem to be obligatory for everybody and must be used alongside your pure thirst cues,” he provides.
After following the suggestions of each the units I used to be testing, I discovered I used to be much less more likely to bonk and as a substitute felt extra energized post-run. I used to be additionally much less more likely to want a nap (except it was a very long term) and skilled much less muscle soreness.

That watch is anticipated to launch within the fall.
One other, Geca, will observe solely hydration, repeatedly, all day. It guarantees to inform the consumer when they’re dehydrating and provides water consumption suggestions. It’s also slated to launch within the fall.
As for non-wearable tech, Betz recommends Hidrate Spark for the shoppers she works with. The insulated water bottle—created after the founders’ good friend had a well being scare—tracks water consumption and lights as much as remind you to drink based mostly in your pre-set hydration targets. And it will probably combine with Apple Watch, Fitbit, and Garmin watches.
“It’s really been confirmed to get individuals to drink extra water,” says Betz.

Not into experimenting and DIY-ing your well being like I’m? A a lot less complicated technique could be to see a dietitian, if in case you have entry, to speak about any hydration issues you’ve gotten. A dietitian can absorb all of the components mentioned above and enable you devise a plan. They’ll assess your physique composition, your diet, and your medical historical past. They’ll order blood work and urinalysis. Then, they may help you include a plan for a way a lot you could hydrate to remain nicely.
“Everybody’s hydration wants are totally different, so it’s necessary to hearken to your physique,” says Dr. Dasgupta.
When you’re capable of hearken to your physique cues for hydrating, you then doubtless don’t want something fancy that can assist you hydrate. But when ou wrestle with ingesting water—or getting sufficient electrolytes whereas exercising—then there’s nothing mistaken with getting some assist.
