Why the classic '8 glasses of water a day' needs to be debunked once and for all.
For many, this could be too much water. Experts say there's a much easier way to get your daily hydration needs met.

Are we drinking too much water or not enough?
We all know that humans need water to survive, but how much just plain water do we actually need to consume each day to be healthy?
If your instinct is to say 6 to 8 glasses of water a day, you're not alone. For many of us, that figure has been ingrained into us since we were kids by health class teachers, family doctors and concerned caregivers alike.
However, needing 8 glasses a day of water is a total and complete myth.
Despite being deeply embedded in our collective conscience, there's little to no scientific evidence to back up the idea that drinking 8 glasses—or any specific number of ounces—of water per day is ideal. This fact might take a minute to digest, since these days so many of us carry water bottles measured in specific ounces to help us stay hydrated and may even track our water consumption with an app or daily planner.
Knowing how many ounces of water we should drink and tracking how much we do drink may give us a satisfying sense of control, but it's largely meaningless. According to the Mayo Clinic, staying hydrated isn't so much about how much water you drink but about how much fluid you consume overall, including from foods and beverages besides water. And that amount is different for every person because every person's body is different.
Additionally, our circumstances are different each day. If you're exercising or sweating from the heat, your body's hydration needs change. If you're sick, pregnant or breastfeeding, your hydration needs change. Certain medications can alter how much fluid your body needs, as can a high-salt diet.
But there must be some kind of guideline, right? We can't just be willy nilly drinking water whenever we feel like it in the age of step counts and sleep tracking apps, can we?

Inadequate hydration is linked to early aging and chronic disease, among other things, so it's important to get enough fluids. The U.S. National Academies of Sciences, Engineering, and Medicine lists adequate daily fluid intake as:
- About 15.5 cups (3.7 liters) of fluids a day for men
- About 11.5 cups (2.7 liters) of fluids a day for women
Some doctors point out that we have a natural mechanism to tell us when we aren't well-hydrated—thirst. "Drink when you're thirsty" may sound like basic advice, but it's what many physicians recommend. However, thirst is a sign that your body is already mildly dehydrated, so some recommend drinking before you get thirsty as well.
Just don't go too far that way, either. Another common myth is that you can't drink too much water, but that's not true. A tragedy in 2023 in which a healthy mother of two drank four bottles of water in about 20 minutes and died of water intoxication highlighted the importance of not drinking too much water too fast. And drinking an excess of water overall, though rarely a problem for well-nourished adults, can make it hard for your kidneys to process properly.
One way to gauge your hydration level besides monitoring thirst is to check your pee. While it doesn't need to be clear(contrary to popular belief) it shouldn't be dark. According to Healthline's handy hydration chart, "lemonade" is about the shade you're looking for. Too clear means you're probably overhydrating. Darker than a light beer and it's time to up your liquid intake a bit.
Water is good. Hydration is important. Pay attention to thirst. Shoot for lemonade-shade pee. That ought to keep you on the right track for getting enough liquid without having to keep track of how many glasses or ounces of water you drink each day.
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
