You're drinking water wrong: Why doctors say temperature matters more than you think

You might be missing out on some serious health benefits.

Could you be more effective with your water intake?

Here’s something we all know but rarely think about: 75% of the human body is made up of water. Essentially, we’re water balloons with legs, or whatever the heckFlubber was. To maintain that internal reservoir, humans need to drink 15 cups of water (for men) and 11 cups of water (for women) daily. It doesn’t take a math whiz to realize that’s a lot of water. To put that into perspective, according to the Omni Calculator (a great online tool that determines a person’s total body water volume using a formula developed by Dr. P.E. Watson), beloved character actor Steve Buscemi is currently carrying around 83.74 pounds of water in his body, or approximately 10 gallons.

But what if you’ve been drinking water, that sweet elixir of life, all wrong? Or, at the very least, ineffectively? Just as every plant has its ideal growing conditions, according to doctors and medical professionals, the temperature of the water we drink matters a lot more than you might think.

Room-temperature, ice-cold and straight from the fridge, slightly warm for no reason at all: when it comes to drinking water, everyone has their own unique methods of getting the job done—but while we continue to chug our preferred water temperatures without question, we might be missing out on some serious health benefits—or even causing ourselves unnecessary discomfort.

Medical experts have discovered that water temperature, when used at the right time, can significantly improve your wellbeing, affecting everything from how we digest our food to how well we perform during workouts. All water hydrates, but the temperature at which you drink it can make all the difference.

Room-temperature water is your digestive system's best friend

When to drink

Good morning! Many dieticians and wellness experts recommend drinking room-temperature water (about 68°F) first thing in the morning to gently activate your gastrointestinal tract (It also promotes regular bowel movements, FYI). This gentle approach is often referred to as “Japanese water therapy,” and encourages sipping 4-5 glasses (about ¾-cup each) upon waking then waiting 45 minutes before breakfast. It’s also great for everyday hydration, since room-temperature water is often easier to gulp.

Why it works

"In Chinese medicine we advocate drinking warm water because of its effect on the digestive system," Dr. Jill Blakeway, a licensed doctor of acupuncture and Chinese medicine explains. “Drinking cold water can congeal the fats in food and because of that can make the digestive system sluggish." Your body absorbs room-temperature water more easily, causing minimal disruption to the digestive system, making it the go-to option for sensitive stomachs.

Ice-cold water is perfect for workouts and hot days

When to drink

This one is for the athletes and fitness gurus: Cold water (around 41°F from the fridge or 60°F from the tap) is your new best friend. Like a refreshing summer breeze, cold water has a natural way of cooling the body down during or after an exercise. It also gives your metabolism a tiny boost: according to research, your body expends about five calories per ounce of ice while warming the water to body temperature.

Why it works

Studies show that drinking cold water triggers a special reflex that helps you to stop sweating sooner, effectively lowering your core temperature and enhancing overall performance. “It turns out that sweating stops before fluid can completely be incorporated into the body,” says gastroenterologist Dr. Brian Weiner. “There’s some kind of reflex that acknowledges liquid intake, and studies have shown that it kicks in more at the cold tap water level.”

Hot water soothes what ails you

When to drink

Hot water (130-160°F) can be incredibly soothing when you’re under the weather. So, if you’re feeling congested or battling a sore throat, a nice mug of hot water might be just what the doctor ordered. A 2008 study found that hot drinks work like a natural remedy, providing quick, lasting relief from runny noses, coughing, sore throats, and fatigue.

Why it works

Like a warm summer rain, hot water creates steam that helps clear sinus congestion, while its pacifying warmth relaxes the gastrointestinal and digestive muscles. In fact, a small study showed that warm water worked wonders for patients recovering from surgery, improving their comfort and digestive health. Warm or hot water can also literally melt away stress, as long as temperatures are kept comfortably warm: water above 160°F can scald your esophagus or damage your taste buds.

When to avoid certain water temperatures

While most doctors agree that drinking enough water is far more important than the temperature, there are specific circumstances to keep in mind:

Shaking head, no, refusing, nope, gifKnow when to say no.Giphy

  • Migraines. Do not drink cold water! Research from 2001 found that the refreshing drink can trigger—or even exacerbate—headaches in those who are already prone to them.
  • Achalasia. If your esophagus is compromised, cold water can worsen symptoms. Try swapping in warm water instead, which can help soothe and relax the lower esophageal sphincter.
  • Hot, sweaty days. Surprisingly, despite what old wives’ tales might say, warm water can actually make you feel less thirsty, which registered dietician Vanessa Rissetto warns "can be dangerous on days when your body is losing water through sweating to try to keep cool."

We all know drinking water is important, but just as a garden thrives with the right care at the right time, you can optimize and customize that all-essential water you drink throughout the day. Whether that’s out of a Stanley tumbler, Owala water bottle, or Yeti flask, is up to you.

Scientists tested 3 popular bottled water brands for nanoplastics using new tech, and yikes

The results were alarming—an average of 240,000 nanoplastics per 1 liter bottle—but what does it mean for our health?

Suzy Hazelwood/Canva

Columbia University researchers tested bottled water for nanoplastics and found hundreds of thousands of them.

Evian, Fiji, Voss, SmartWater, Aquafina, Dasani—it's impressive how many brands we have for something humans have been consuming for millennia. Despite years of studies showing that bottled water is no safer to drink than tap water, Americans are more consuming more bottled water than ever, to the tune of billions of dollars in bottled water sales.

People cite convenience and taste in addition to perceived safety for reasons they prefer bottle to tap, but the fear factor surrounding tap water is still a driving force. It doesn't help when emergencies like floods cause tap water contamination or when investigations reveal issues with lead pipes in some communities, but municipal water supplies are tested regularly, and in the vast majority of the U.S., you can safely grab a glass of water from a tap.

And now, a new study on nanoplastics found in three popular bottled water brands is throwing more data into the bottled vs. tap water choice

Researchers from Columbia University used a new laser-guided technology to detect nanoplastics that had previously evaded detection due to their miniscule size.

The new technology can detect, count and analyze and chemical structure of nanoparticles, and they found seven different major types of plastic: polyamide, polypropylene, polyethylene, polymethyl methacrylate, polyvinyl chloride, polystyrene, and polyethylene terephthalate.

In contrast to a 2018 study that found around 300 plastic particles in an average liter of bottled water, the study published in the journal Proceedings of the National Academy of Sciences in January of 2024 found 240,000 nanoplastic particles per liter bottle on average between the three brands studied. (The name of the brands were not indicated in the study.)

As opposed to microplastics, nanoplastics are too small to be seen by microscope. Their size is exactly why experts are concerned about them, as they are small enough to invade human cells and potentially disrupt cellular processes.

“Micro and nanoplastics have been found in the human placenta at this point. They’ve been found in human lung tissues. They’ve been found in human feces; they’ve been found in human blood,” study coauthor Phoebe Stapleton, associate professor of pharmacology and toxicology at Rutgers University’s Ernest Mario School of Pharmacy told CNN Health,

We know that nanoplastics are making their way into our bodies. We just don't have enough research yet on what that means for our health, and we still have more questions than answers. How many nanoplastics does it take to do damage and/or cause disease? What kinds of damage or disease might they cause? Is whatever effect they might have cumulative? We simply don't have answers to these questions yet.

That's not to say there's no cause for concern.

We do know that certain levels of microplastic exposure have been shown to adversely affect the viability of cells. Nanoplastics are even smaller—does that mean they are more likely to cause cellular damage? Science is still working that out.

According to Dr. Sara Benedé of the Spanish National Research Council’s Institute of Food Science Research, it's not just the plastics themselves that might cause damage, but what they may bring along with them. “[Microparticles and nanoparticles] have the ability to bind all kinds of compounds when they come into contact with fluids, thus acting as carriers of all kinds of substances including environmental pollutants, toxins, antibiotics, or microorganisms,” Dr. Benedé told Medical News Today.

Where is this plastic in water coming from?

This study focused on bottled water, which is almost always packaged in plastic. The filters used to filter the water before bottling are also frequently made from plastic.

Is it possible that some of these nanoplastics were already present in the water from their original sources? Again, research is always evolving on this front, but microplastics have been detected in lakes, streams and other freshwater sources, so it's not a big stretch to imagine that nanoplastics may be making their way into freshwater ecosystems as well. However, microplastics are found at much higher levels in bottled water than tap water, so it's also not a stretch to assume that most of the nanoplastics are likely coming from the bottling process and packaging rather than from freshwater sources.

The reality is, though, we simply don't know yet.

“Based on other studies we expected most of the microplastics in bottled water would come from leakage of the plastic bottle itself, which is typically made of PET (polyethylene terephthalate) plastic,” lead author Naixin Qian, a doctoral student in chemistry at Columbia University, told CNN Health. “However, we found there’s actually many diverse types of plastics in a bottle of water, and that different plastic types have different size distributions. The PET particles were larger, while others were down to 200 nanometers, which is much, much smaller.”

We need to drink water, and we need to drink safe water. At this point, we have plenty of environmental reasons for avoiding bottled water unless absolutely necessary and opting for tap water instead. Even if there's still more research to be done, the presence of hundreds of thousands of nanoplastics in bottled water might just be another reason to make the switch.

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

That doesn't mean that's how much water you should drink. Fluids can be found in food—many fruits and vegetables are high in water content and count toward hydration. Any milk you drink and even yogurt or cottage cheese you consume adds to your fluid intake. Soups and broths? Super hydrating. Other beverages, even ones that contain caffeine as long as you don't overdo it, count as well. And again, those numbers are just a general guideline. Your body size, overall health, environment and lifestyle all influence your own specific hydration needs.

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.

Most pregnant women know what they need to bring to the hospital. Doris' list had something extra.

For Doris, the list was very different.

Bathrobe. Socks. Insurance card. Snacks.

Sound at all familiar? Maybe, maybe not.

These items would commonly be found on a checklist of things that expecting parents should bring to the hospital with them — in the U.S., anyway.

But what is that list like in other parts of the world?

For Doris, that list included water.

Doris, who lives Morogoro, Tanzania, had to bring her own water to the health center where she was giving birth in 2014. The water she brought was used to clean the nurse's hands, clean the delivery area, and wash the babies (she had twins!). Unfortunately, the water Doris brought ran out before she was able to wash herself or her clothes, so she had to wait 24 hours before cleaning herself.

I'll let Doris tell the story herself:

Lack of access to clean water in Tanzania is a very big deal.

Everything turned out alright for Doris and her babies, but thousands of other women aren't as lucky. But there are ways to help: Organizations and individuals are pitching in to help build water taps, rainwater tanks, and latrines in Tanzanian hospitals, and they're making a huge difference.

"I want to express my gratitude to the health workers ... because they have a great sense of humor with the patients. But the problem is the availability of enough water." — Doris Alikado
