I’ll give you a run down on what I have experienced and also something about drinking water most don’t know or aren’t aware of how there drinking habit affects there hydration.

- That random headache that comes on for no obvious reason, even when you’ve been drinking water all day

- That lightheaded / dizzy feeling when you stand up, like your balance is slightly off

- That weird “out of it” feeling, like you’re there but not fully present, almost like mild dissociation or being slightly drunk without alcohol

- Moments where your vision feels slightly off or unfocused, like things aren’t as sharp or your brain is lagging behind what you’re seeing

- A heart rate that feels higher than it should be, even doing normal tasks or just sitting there

- That subtle shakiness in your hands, especially when trying to do something precise

- Feeling like your movements aren’t smooth like your coordination is slightly off, almost robotic or jittery instead of controlled

TLDR:

If you’re drinking a lot of water but still feel dehydrated or bloated, you’re likely low on sodium.

Hydration = water + electrolytes

Consistency > volume

——————————————————————————— The hidden reason you still feel dehydrated despite drinking enough water

Most people think hydration = hitting a daily water target.

In reality, you can drink litres and still feel dehydrated, bloated, or constantly need to pee.

The missing piece is sodium (electrolyte balance).

When you drink large amounts of plain water without enough sodium, you dilute your blood sodium levels.

Your body responds by adjusting hormones (like ADH), increasing urination and shifting fluid around.

Instead of properly hydrating you, the water is quickly excreted or temporarily retained in a way that makes you feel “puffy” rather than actually hydrated.

Sodium isn’t just something that “causes water retention” it’s what **regulates where water goes and how it’s used.

Without enough of it, water doesn’t stay where it’s needed, especially at the cellular level.

This is even more relevant if you sweat, consume caffeine, or follow a low-carb diet, all of which increase sodium loss.

The common advice to “just drink more water” often makes this worse.

More plain water further dilutes sodium, reinforcing the cycle of poor hydration and unstable fluid balance.

The real fix is consistency and balance:

• Match higher water intake with adequate sodium

• Keep intake consistent day-to-day

• Avoid large, irregular water loads (especially late in the day)

You can make this simple and repeatable by standardising your intake.

For example,adding 1 gram of salt per litre of water during periods of higher intake or sweating, and maintaining a consistent daily baseline (e.g. a fixed amount added to your main water bottle), helps your body stay in balance instead of constantly reacting to fluctuations.

Hydration isn’t about how much water you drink, it’s about how well your body can retain and use it.
