Introduction
You drink your 8 glasses, carry a bottle everywhere, and tell yourself you're hydrated. But what if I say the way you're drinking water is working against your body?
This is one common question that keeps coming up again and again in our iThrive Tribe community groups and honestly, it's one of the most important health conversations you can ever have. As hydration isn't just about how much water you drink, rather it’s also about what kind of water, what's in it, and how your cells actually absorb it.
This blog will be diving deep into what kind of water you should drink, what’s in it and how your cells actually absorbs it.
Water is not just water

I’ll tell you something most of you would’ve never realised: plain water especially demineralised or RO purified water without any minerals is not the same as hydrating water.
Your cells don't just absorb water passively like a sponge. Water enters and exits cells through channels regulated by electrolytes which primarily sodium, potassium, magnesium, and chloride. These minerals are what actually pull water into the cell and keep it there. Without them, water flows right through you. You drink, you pee, and you're still thirsty… the loop is on and on.
Minerals such as calcium, magnesium, as well as potassium are essential not just for bones and muscles, but also for neuromuscular transmission, enzymatic activity, oxygen transport, and basic cellular function. In lay man language I can say without minerals, your body can't do much with the water you give it.
The problem with RO water
Reverse osmosis water purifiers like Kent RO and similar systems definitely does a fantastic job of removing contaminants, heavy metals, fluoride, and bacteria from drinking water. That part is honestly valuable, especially here in Indian cities where tap water quality is inconsistent.
But let me first talk about the catch: RO filtration strips everything including the naturally occurring minerals that make water beneficial. So basically what you're left with is very clean, very empty water.
Drinking demineralised water consistently, especially during summer or physical activity, can actually dilute your body's electrolyte balance. The result? You may be drinking plenty of water but still experiencing fatigue, brain fog, muscle cramps, or persistent thirst, which are all the classic signs of inefficient hydration.
The fix is simple: remineralise after purification.
- Add a small pinch of Himalayan pink salt to your water bottle
- Use a trace mineral supplement like Utah Sea Trace Minerals or BodyBio Minerals, available on iHerb just a few drops per litre
- Add coconut water to your hydration routine, especially post-exercise.
- Drop in a pinch of magnesium bisglycinate or use a magnesium-rich mineral supplement as magnesium plays a starring role in cellular energy production and muscle recovery
And no this is not about adding flavour. It's about turning water that your body will pass through, into water that your body can actually use.
The summer hydration trap

During summer, the stakes are higher than usual. Rising temperatures push your body into continuous fluid stress like you're sweating more, your blood vessels are dilating, and you're losing water and minerals at an accelerated rate. This is when poor hydration practices really start to show up.
What happens when you're sweating but only replacing fluid without minerals?
- Electrolyte depletion I mean sodium, potassium, and magnesium drop, impairing every system that depends on them
- Heat intolerance like your thermoregulation breaks down, making you feel the heat far more intensely
- Brain fog and fatigue even mild dehydration impacts cognition and mood
- Circulatory strain low plasma volume causes your heart to work harder, leading to dizziness and weakness
- Cellular inefficiency your mitochondria need proper hydration to function and without it, energy production at the cellular level falters
The major takeaway here is that summer doesn't just increase your need for water, it rather increases your need for minerals. Hydrating smarter beats hydrating more.
How to actually drink water: Practical Habits
Beyond what you put in your water, how you drink matters too.
Sip, and please don't gulp. Drinking large amounts of water at once overwhelms your kidneys and passes through without being absorbed well. Sipping consistently through the day allows your cells to keep pace.
Drink water away from meals or at least don't flood meals with large quantities.
A small amount of water with food is fine, but large quantities can dilute digestive enzymes and stomach acid.
Morning hydration matters. After 7 to 8 hours of sleep, you wake up mildly dehydrated. Start your morning with a glass of mineral-rich or lightly salted water before coffee.
Listen to your body, never chase not the number just for the sake of it. The 8 glasses a day rule is a general guideline, and not a universal prescription. Your needs vary on the basis of your size, activity level, climate, and diet. Pale yellow urine is a good practical indicator of adequate hydration.
Eat your water too. Foods such as cucumber, watermelon, muskmelon, and citrus fruits are quite refreshing and they also deliver water alongside micronutrients and electrolytes that support absorption. In summer especially, these can prove to be your allies.
What about Kangen water and ionised water?
Kangen water machines have become popular in wellness circles, and there's a lot of marketing around their alkaline, ionised output. It's worth understanding what these machines actually do and offcourse what they don't.
Kangen machines work through electrolysis passing an electrical current through water to separate it into alkaline and acidic streams. Sources also claim this also structures the water, but this is where the science gets murky.
Water structuring is about the strength of hydrogen bonds between water molecules. Electrolysis, by its very nature, breaks hydrogen bonds to separate the water's components. Ionisation through electrical hydrolysis creates a water that may carry an electrical charge, but that charge doesn't equal molecular structure. The two are not the same thing.
There are also practical concerns:
- The hydrogen infused by electrolysis is unstable and dissipates quickly, you need to drink it immediately after pouring for any potential benefit
- The machines do not remineralise water; alkaline mineral compounds produced through the process may not be recognised by the body, and in people with suboptimal kidney function, could accumulate in tissues
- Tap water TDS (total dissolved solids) significantly affects the machine's output so if the source water is too hard or too soft, the hydrogen concentration and machine performance both suffer
None of this means ionised water has no benefits, molecular hydrogen does have genuine antioxidant research behind it. But there are simpler, more stable, and far more affordable ways to get those benefits than a machine costing several lakhs. Adding trace minerals and focusing on clean, remineralised water gets you most of the way there.
If you're considering an alkaline or hydrogen water setup, the most important thing is to also remineralise whatever water you're drinking. Any RO system works fine as a base, just put the minerals back in after.
A simple hydration protocol to start today

You don't need expensive equipment. Here's what actually moves the needle:
- Filter your water any good RO purifier handles contaminants well
- Remineralise after filtering Himalayan pink salt, trace mineral drops, or coconut water
- Sip through the day don't wait until you're thirsty, that's already mild dehydration
- Prioritise minerals in summer add magnesium bisglycinate, eat hydrating foods, and consider a natural electrolyte drink
- Start your morning right warm mineralized water before anything else
- Rinse produce with ozone water if available, it's an effective way to remove pesticide residues and surface contaminants without adding chemicals to your food
Key Takeaway
Hydration isn’t about drinking more water. It’s about helping your cells actually use it.
If you’re still feeling tired, thirsty, bloated, dizzy, or experiencing brain fog despite drinking plenty of water, it may be time to look beyond quantity and focus on water quality, mineral balance, and hydration habits.
Start simple: filter your water, remineralise it, sip consistently, and support hydration with minerals and water-rich foods. Your body doesn’t just need water, it also needs the right environment to use it.
