Does Sodium Dehydrate You? Let’s Unpack the Salty Truth

Sodium = Bad? Not So Fast.

We get it — sodium has a bit of a PR problem. It’s often blamed for bloating, high blood pressure, and dehydration. So it’s no surprise people ask: “Does sodium dehydrate you?”

Let’s clear that up — with facts, not fear.

What Sodium Actually Does

Sodium is one of your body’s most important electrolytes. It helps:

Maintain fluid balance
Regulate blood pressure
Transmit nerve signals
Support muscle function

Basically, sodium isn’t the villain — it’s a key player in keeping you from feeling like a wilted houseplant after a workout.

So... Can Sodium Dehydrate You?

Technically? Not when consumed properly. Sodium doesn’t dehydrate you — it helps your body retain water, especially during sweating, heat, or exercise.

BUT — and this is the nuance — excess sodium without enough water intake can throw off your fluid balance. That’s why eating super salty foods without drinking water can make you feel parched.

TL;DR:

Too much sodium + not enough water = thirst.
Balanced sodium + proper hydration = electrolyte harmony.

Why Mizu Lab Uses Sea Salt (and Not Table Salt)

At Mizu Lab, we use sea salt as our source of sodium — and here’s why:

It’s less processed
It contains trace minerals
It dissolves smoothly into water (aka no salty sludge)
It supports hydration without overdoing it

Each stick of Mizu Lab contains a measured, thoughtful dose of sodium — just enough to support hydration, especially when you’re active, traveling, or living your best multitasking life.
