The Missing Piece in Nervous System Regulation: Why Electrolytes Matter More Than You Think
When we talk about nervous system regulation what do we hear most often?
Work on your breathing, mindset, boundaries; learn to feel safe in your body.
And all of those are big portions of the puzzle. But an important piece that is often missed is what’s going on inside our body. You can be doing all the right things, but if your nervous system isn’t getting what it needs to function properly, then you’ll continue to feel anxious, tired, and just not like yourself.
I see this all the time. It’s so easy to focus on all those outside pieces, that we neglect the inside ones.
And one of the most overlooked pieces I see? Electrolytes.
The Stress / Depletion Loop
With so many different processes in the body, it’s really easy to get stuck in loops. And this is one area where I see so many people get stuck without even realizing it.
Stress uses up electrolytes. When your Fight/Flight triggers on, your body requires electrolytes for all of those processes. Your heart beating faster, your muscles contracting, faster breathing - even just the signals from the nerves - all require electrolytes. So if this stress cycle is triggering all day long, you’ll quickly drain your body of its electrolytes.
And here’s why it’s a loop: low electrolytes make your nervous system more sensitive to stress. When you’re low on these vital minerals, now your nervous system is under threat because it can’t protect itself the way it needs to.
So it becomes this cycle:
You’re stressed → your body burns through minerals
Your levels drop → your system becomes less resilient
You feel more reactive → which creates more stress
And around and around it goes.
So the important question is… “does my body have what it needs to handle my stress load?”
What Electrolytes Actually Are (and Why They Matter)
I don’t know about you, but I'm more motivated to prioritize things when I actually understand them. So let’s dig into what electrolytes are and why they impact the nervous system so much.
Electrolytes are minerals — like sodium, potassium, and magnesium — that carry an electrical charge when they’re in fluid. That’s why they’re called electro-lytes!
And it’s that electrical charge that makes them so important. Because your body — especially your nervous system — runs on electrical signals. (Yes, we are electrical beings!)
Your Nervous System Depends on Them
When we talk about the nervous system it can sound a little abstract, but here are a few things that are important to understand. Your brain is constantly sending messages to your body:
“Contract this muscle.”
“Slow your breathing.”
“Stay alert.”
“Relax.”
And it does this through tiny electrical signals traveling through your nerves. And guess what? Those signals depend on electrolytes in order to work.
Minerals like sodium move in and out of your nerve cells, creating changes in electrical charge. That shift is what allows a signal to fire—and then travel. It’s like a ripple effect moving down the nerve.
So when your body is low in these minerals, those signals don’t fire as smoothly. And that can feel like:
being more reactive than usual
having a harder time calming down
feeling “on edge” without knowing why
Remember, your body is always trying to function optimally. Your base programming is to heal, you’re always searching for homeostasis, or balance. So when something is off, it’s often because the body doesn’t have the tools it needs to function the way it’s supposed to.
Yes, we’re impacted by everything on the outside, but sometimes you need to look at what is lacking internally too.
A Necessary Bandaid
Being low in electrolytes is rarely the only root cause of your stress response being higher. But it can absolutely be a contributor.
Making sure you’re getting sufficient electrolytes for your body to function optimally is key in overall health, but especially if you have higher stress.
But you don’t want to stop there. Optimizing electrolytes can help prevent other issues while you’re in the midst of a stressful season, but you also want to make sure your stress response is appropriate in the first place. You don’t want to only chase symptoms, but get down to what’s triggering your response to begin with.
Some solutions are more of a bandaid, but sometimes a bandaid is necessary. Whether you’re supporting your body while under stress, or trying to build back stronger connections as you heal your nervous system, electrolytes can be an invaluable tool.
Let’s Break This Down Simply
Now that you know that your body needs electrolytes, let’s dig into what the main ones are that we want to look at, and some of the places where you can get more of them.
You don’t need to memorize all of this—but understanding the basics can help you recognize what your body might be asking for. And you might find that one of these stands out and makes you think… oh, that’s me.

What It Can Feel Like When You’re Low
This doesn’t always show up in obvious ways. It’s usually pretty subtle, but let’s walk you through some of the things to be aware of.
You might notice:
fatigue that feels heavier than usual
headaches
dizziness when standing
muscle tightness or cramping
And from a nervous system perspective:
feeling anxious or on edge
“wired but tired”
brain fog
low stress tolerance
Not everyone experiences all of these — but when you start connecting the dots, it can make a lot more sense.
Why So Many People Are Depleted of Electrolytes
With our fast paced lifestyle, being low in electrolytes is incredibly common, and there are a few big reasons why.
Chronic stress
Stress increases your body’s demand for minerals, and causes you to lose more of them.
The way we eat
The standard diet tends to be lower in mineral-rich foods and higher in processed options that don’t replenish what we need.
Modern hydration
Filtered water is important for removing contaminants, but it often removes minerals too.
Daily habits
Caffeine, alcohol, intense exercise, poor sleep — all of these increase depletion.
More Than Just Nervous System
Electrolytes have a big impact on nervous system health which is always my main concern, but there are a lot of other body processes that require electrolytes in order to function. Let’s look at just a few of these places to be aware of.
It Affects Your Muscles Too (Including the Ones You Don’t Think About)
Electrolytes also control how your muscles function.
And that includes:
your shoulders and neck (where we all hold so much stress)
your digestive system (your gut is lined with smooth muscle to move everything through)
your heart
For a muscle to contract, it needs calcium. But for that muscle to relax? It needs magnesium.
So you can think of it like this:
Calcium = contraction
Magnesium = relaxation
If that balance is off, you might notice:
tension that doesn’t fully release
tight muscles or jaw clenching
a body that doesn’t feel like it can soften
Interesting side note:
When we run a Hair Tissue + Mineral Analysis Lab, a sign that someone has been under a lot of stress is high calcium levels and low magnesium levels.
This is because when we’re in fight or flight, our nervous system is focused on muscle contraction. We need our muscles to have easy access to calcium in order to fight or flee. So the body will actually pull calcium out of places like our bones to make sure there’s a steady supply — this is why calcium will show up as high.
Magnesium, on the other hand, will be low because the body is trying to continuously come back down out of that heightened state. And because magnesium isn’t stored well and is lacking in most diets, stress will deplete it over time.
How Electrolytes Impact Hydration
Hydration is such a huge piece to overall health, but without electrolytes, water isn’t able to benefit the body like it should.
Electrolytes — especially sodium — help direct water in and out of your cells.
There’s a constant movement happening (called osmosis), where water shifts to where it’s needed most.
Without enough electrolytes:
water isn’t properly absorbed
cells can become depleted or imbalanced
So you can be:
drinking plenty of water
but still feeling tired, foggy, or depleted
Side note: If you’re filtering your water (which is often important), just know that some filtration systems also remove beneficial minerals. In this case it’s important to be adding minerals back in.
You can check your local water quality here https://www.ewg.org/tapwater/ to better understand what’s in your water.
Your Body Is Always Trying to Stay in Balance
Your body is constantly working to keep things stable.
One of the ways it does that is by regulating its internal pH — how acidic or alkaline your body is. Your blood, for example, stays within a very tight range. Even small shifts can affect how your body functions. Electrolytes help keep that balance steady.
They act like buffers, adjusting and stabilizing things behind the scenes so your body can function the way it’s supposed to.
This is also why something as simple as your breath can have such a powerful impact. When you breathe, you’re not only taking in oxygen—you’re also breathing out CO₂. When CO₂ builds up, it combines with water to form an acid. Deep, slow breathing helps regulate that balance, while also calming your nervous system at the same time.
This is why we don’t just focus on one thing to support our bodies; it’s a lot of different pieces that bring everything back to balance.
They Don’t Work Alone
While we can be low in individual electrolytes, it’s important to understand that electrolytes don’t work in isolation—they work together.
For example:
Sodium and potassium need to be balanced in order to be effective
Magnesium supports both of them
Calcium relies on magnesium to function properly
So we don’t want to spend all our time focusing on only one—we want to support the system as a whole.
You can do an at home Minerals + Metals lab to see what’s happening with your electrolyte balance to give us a better idea of exactly what needs to be supported. If that’s something you’re curious about and it’s within your budget, it can be a really helpful tool. But if not, for most people simply prioritizing giving your body plenty of access allows you to rebalance. Here’s the lab I recommend here: https://equi.life/products/hair-tissue-mineral-analysis-test
Nature’s Electrolytes
I’m always fascinated by how so much of what we need for our body to function just happens to be packaged perfectly for us in certain foods.
If you’re looking to support your electrolyte intake, here are some whole foods that contain them in a really balanced way:
Watermelon
Coconut water
Citrus fruits
Leafy greens
Broths
These foods naturally provide a combination of:
water
potassium
sodium
magnesium
Which is exactly what your body is designed to use.
A Simple Way to Start
You don’t need anything complicated to begin supporting this. One of my favorite simple practices is a glass of water with:
half a lemon squeezed in
a pinch of mineral-rich sea salt
It’s a simple, natural way to give your body:
hydration
trace minerals
gentle digestive support
(And yes… it helps wake things up in the morning too.)
What to Look For in Electrolyte Supplements
Since it’s not always convenient to carry around watermelon with you, a lot of people — myself included — use electrolyte mixes to support daily intake. If you want something convenient, these can be really helpful tools.
Look for:
clean ingredients
balanced mineral profiles
minimal additives
Avoid:
artificial sweeteners
unnecessary dyes or fillers
I don’t love most of the name brand electrolyte mixes since so many of them have added sugars and dyes which only create more stress in the body. On top of that, not every form of minerals are easy for our body to use and assimilate. Ingredients matter so be picky with the ones you reach for.
There are a lot of really great options out there, but here is one I personally use and like: Paleovalley – Essential Electrolytes
I love the flavor, it dissolves easily into water, and I trust their sourcing.
Some things I like about it:
Full-spectrum electrolytes from whole food sources (sea salt, coconut water, seaweed, seawater)
60+ naturally occurring trace minerals
No artificial flavors or dyes
No added sugars
Non-GMO and gently processed

Final Thoughts
I wish there was a magic pill that just automatically puts your body back in balance. And while that doesn’t exist, the good news is that supporting our body doesn’t have to be complicated.
Oftentimes, it's as simple as giving your body what it’s been missing. Your body is always trying to find balance.It’s always trying to regulate, heal, and support you. But it can only do that with the tools it has access to. This is just a simple way for us to give our body what it’s asking for, what it needs to function optimally.
So if you think electrolytes are something you’d benefit from focusing on, just start small. Add a pinch of sea salt and lemon juice to your water. Be more intentional about your food. Pay attention to how your body responds.
It’s amazing how much better we feel inside and out when we give our body the building blocks it needs to thrive.
