author avatar Dr. Eric Berg 09/16/2023

Do you think you're doing your body a favor by chugging down gallons of water daily?

You might want to think again. Common drinking water mistakes, such as overhydration, ignoring electrolyte balance, and gulping down cold water, can throw off our bodies in surprising ways.

You've probably heard about the importance of staying hydrated for health. But did you know that how, when, and what kind of water you drink matters too?

In this enlightening journey through hydration do's and don'ts, we'll unpack hidden dangers lurking in tap waters while exploring deceptive hydration sources like coffee or soda.

We’ll delve into understanding your unique fluid needs based on factors like exercise or diet types.

Ahead lies a treasure trove of information set to change how you hydrate for good. So let’s dive right in!

The Importance of Electrolyte Balance in Hydration

Water is life. But just chugging gallons won't cut it for proper hydration. What you need to get right is the balance between water and electrolytes - specifically sodium and potassium.

The Role of Sodium and Potassium in Hydration

Sodium and potassium are like two sides of a coin – both vital, but they must be balanced. Why? Because their interaction controls fluid balance inside your cells.

Research shows that if this balance gets disrupted, problems can start cropping up.

Ever heard about hyponatremia? It's a condition where there isn’t enough sodium in the blood due to excessive water intake without sufficient electrolytes.

Yes, you read that right: too much water can cause dehydration.

This doesn't mean we should all go salt-crazy, though. A dash here or there on meals may help with small needs, but drinking salty fluids isn’t typically necessary unless engaging in long-duration exercise or when sick with vomiting or diarrhea.

Avoiding Dehydration Missteps

Maintaining optimal hydration isn't as simple as 'drinking 8 glasses per day'. Everyone has unique needs depending on factors such as age, sex, weight, climate conditions even diet choices.

Men require roughly 3 liters, and women around 2 liters daily under normal conditions.

The Hidden Dangers of Tap Water

But where you get your water from matters too. Did you know that tap water might contain harmful substances?

It's a real witch's brew, from chlorine and fluoride to glyphosate and nano-sized plastic particles. Using a good filter can help keep these nasties at bay.

Bottled Water vs. Tap Water

Weighing up the pros and cons between bottled and tap water isn't as simple as it seems.

Understanding Your Fluid Needs

Your body's fluid needs can be influenced by various factors, from the weather outside to the type of diet you're following.

Rather than adhering to a single set quantity of water, your hydration requirements should be adjusted according to the circumstances. You must adapt your intake based on what's happening in and around you.

Dehydration and Weight Loss

Do you comprehend that dehydration could be a hindrance to your weight-loss endeavors? But did you realize it might also reduce your balance when transitioning between diets?

Things get trickier if you switch from a high-carb diet, where the body retains more fluid, to a ketogenic diet.

The reason is straightforward: When reducing carbs drastically (a hallmark of any ketogenic plan), there’s an initial phase during which your body will burn through its glycogen stores for energy.

This process releases water leading to increased urination—a phenomenon often called 'keto flu' due to accompanying symptoms such as fatigue and headaches.

To counteract this potential pitfall, keep tabs on how much water you’re drinking while paying attention to signs of dehydration like dry mouth or feeling overly thirsty—your dashboard indicators telling you need more fluids.

Other everyday situations that increase our fluid needs include exercise – especially if we sweat heavily; being sick with vomiting or diarrhea; and exposure to extreme temperatures, whether hot or cold.

All these circumstances demand us to replenish lost fluids promptly, so don’t forget to hydrate wisely before reaching for another cup of coffee just because it’s liquid.

Remember, there's no one-size-fits-all approach to hydration and weight loss. Realize the particular needs of your body and adapt accordingly.

You may not even pause to consider your hydration source for a refreshing drink. But did you know that drinking tap water can come with hidden dangers?

The Environmental Protection Agency sets safety standards for drinking water, but harmful substances such as chlorine and fluoride may still lurk in your glass.

Bottled Water vs. Tap Water

The bottled and tap water debate is often rooted in convenience versus environmental impact. While 'healthy' bottled waters promise purity and taste, they contribute significantly to plastic pollution.

But before we write off tap water, let's consider its potential hazards. Typical contaminants found in unfiltered taps include glyphosate from pesticides and nano-sized plastic particles shed by pipes or fixtures.

You'd be surprised how many people are unaware of these risks when sipping their seemingly innocent H20 straight from the faucet.

Glyphosate: A Hidden Threat?

Glyphosate, a common herbicide used worldwide, has been linked to various health issues like gut disorders and certain cancers. It seeps into groundwater after being sprayed on crops—ending up in our home faucets if not adequately filtered.

Nano-Sized Plastic Particles: What Are They Doing In My Drink?

A shocking fact about modern life is that plastics are everywhere—even where we least expect them.

Nano-sized plastic particles have made their way into our drinks due to the degradation of larger plastics over time or shedding from pipe systems. The long-term effects on human health remain largely unknown, which is concerning.

Filtering Out The Bad Stuff

The good news? Take steps to lower your contact with these potentially dangerous substances. Investing in a high-quality water filter can help remove harmful substances from tap water before you drink it.

But let's not forget all filters aren't made the same. Some might only deal with chlorine or fluoride and ignore glyphosate. So, it's crucial to do your homework and pick a filter that takes on as many pollutants as possible for the purest, safest sip of water.

The Impact of Water Temperature on Digestion

When it comes to drinking water, the temperature matters more than you might think. It's not just about quenching your thirst or cooling down; it can also significantly impact your digestion.

Research has revealed that consuming a lot of very cold water could impede the functioning of the vagus nerve, which is essential for digestion.

This means you could put your digestive system into low gear without knowing when you're reaching for an icy glass of H2O after a workout or during a hot summer day.

Warm Water and Digestion

What about warm temperatures if extreme cold isn't good for our insides? Is there such a thing as 'just right' when discussing drinking water?

Sipping warm water is like giving your digestive system a gentle hug. The warmth aids in breaking down food and enhances nutrient absorption – essentially making sure all those greens you ate don’t go to waste.

Besides aiding digestion, warm water offers other health benefits too. From boosting blood circulation to relieving nasal congestion – this simple habit could transform your well-being beyond belief.

Cold Water - A Shock to Your System?

We've already mentioned how excessive intake of ice-cold drinks can mess with our gut function by slowing down the vagus nerve. But why does this happen?

Your body needs to maintain a steady internal temperature. It has to work harder to return to its comfortable state when introducing something icy. This process can divert resources away from digestion.

Think of your stomach like a cozy fireplace and the food you eat as firewood. Drinking ice-cold water is akin to throwing a bucket of snow onto that warm blaze - it's bound to slow things down.

A Balanced Approach

The key takeaway isn't necessarily 'cold bad, warm good.' It's about balance and understanding how different temperatures can uniquely affect our bodies.

Looking to boost your digestion? Drinking lukewarm or room-temperature water could be better than grabbing a cold one.

The Deceptive Hydration Sources

While it's common knowledge that staying hydrated is crucial for overall health, not all beverages are created equal regarding hydration. Some drinks, such as coffee, tea, and soda, may seem hydrating but can contribute to dehydration.

Both coffee and tea can act as mild diuretics, meaning they stimulate urine production in your body, which could lead to dehydration if not monitored carefully.

That means they increase the urine production in your body, which can lead to dehydration if you're not careful.

These beverages might quench your thirst momentarily or even provide an energy boost due to their caffeine content. But remember this: despite their high fluid content, they're far from being optimal hydration sources.

Soda is another deceptive beverage often mistaken as a hydrating drink because of its water component. But don't let those fizzy bubbles fool you.

Not only does soda fail at adequately hydrating your body, but it also has other harmful effects on your health.

Coffee and Tea: More Than Just Caffeine Boosts

We all love our morning cuppa - coffee or tea – for that much-needed wake-up call after snoozing the alarm clock too many times. However tempting that second (or third) cup might be, remember these brews aren't harming your hydration levels.

Studies show excessive coffee or tea could leave you feeling parched rather than refreshed. They act as mild diuretics, causing increased urination which can, in turn, lead to fluid loss and potentially dehydration.

Eye Floaters and Drinking Water

When it comes to eye floaters, maintaining overall eye health is crucial. While staying hydrated by drinking adequate water daily is essential for your well-being, clarifying that there isn't a direct, scientifically proven link between water consumption and reducing eye floaters is essential.

Suppose you're wondering how to reduce floaters in the eyes naturally. In that case, you might explore various strategies, including a balanced diet rich in eye-healthy nutrients and antioxidants, regular eye exercises, and protecting your eyes from excessive UV exposure.

However, if floaters persist and significantly disrupt your vision, you should consult an eye specialist for a comprehensive evaluation and appropriate guidance.


Let's recap what we've learned about common drinking water mistakes. We now understand that electrolyte balance is vital when hydrating, and too much water without adequate sodium can lead to dehydration.

We delved into understanding individual fluid needs influenced by factors like exercise, diet type, and even the temperature around us. Remember - adapting your hydration strategy based on these variables is crucial.

We discovered the hidden dangers of tap water and how using a good filter can protect our health. Don't forget – bottled isn't always better!

The importance of considering water temperature for optimal digestion was also highlighted - avoid gulping down ice-cold waters after meals!

Last, be wary of deceptive hydration sources such as coffee or soda; they might not hydrate you effectively despite their high fluid content.
