Magnesium, Stress & Sleep: The Quiet Power of Floating to Rebalance the Body

For so many of us, the weight of modern life settles into the body. We feel it in our shoulders, in the restless way we sleep, in the vague fog of fatigue or anxiousness that doesn’t quite go away. And while wellness is never one-size-fits-all, there’s a quiet mineral often overlooked in these moments: magnesium.

Magnesium is essential to the body's ability to regulate stress, support muscle function, manage blood sugar, and even ease into rest. It helps balance the nervous system, keeping us from getting stuck in fight-or-flight mode. And yet, studies suggest that a significant portion of the population may not be getting enough of it.

The Symptoms of Low Magnesium

Low magnesium can look like many things: muscle cramps or spasms, chronic fatigue, tension headaches, difficulty sleeping, and heightened anxiety. Some people experience numbness or tingling; others feel a low-level ache that doesn’t resolve. These symptoms may be subtle at first, but over time, they take a toll.

Why Magnesium Matters

Magnesium plays a role in over 300 enzymatic reactions in the body. It supports everything from cellular energy production to cardiovascular health, and even helps regulate mood by interacting with neurotransmitters in the brain. Magnesium is also known to help muscles relax after contraction, which makes it a critical element not only for physical recovery, but also for helping the body downshift into rest. In short, it's a foundational mineral that quietly supports the systems we rely on every day.

Sleep, in particular, is closely tied to magnesium status. This mineral helps regulate melatonin, the hormone responsible for sleep-wake cycles, and supports deep, restorative sleep by calming the nervous system. Low magnesium is often linked with restless sleep, nighttime awakenings, and difficulty falling or staying asleep. Supporting magnesium levels—especially in soothing environments like a float—can be a meaningful step toward better rest.

Supplementing with magnesium through food or oral supplements is a common approach, but another increasingly embraced method comes through something deeply relaxing: floating.

What Is Float Therapy?

Floatation therapy, or simply "floating," involves resting in a warm, quiet tank filled with water supersaturated with magnesium sulfate (Epsom salt). The water is so dense with salt that the body floats effortlessly, allowing muscles to release tension and the mind to enter a deep state of rest.

While the experience itself is soothing, what’s especially intriguing is the role magnesium may play in this equation.

Can Magnesium Be Absorbed Through the Skin?

Many health professionals and researchers believe that magnesium can be absorbed transdermally (through the skin), particularly in the high concentrations found in float tanks. While the scientific community continues to study the extent and mechanisms of this absorption, enough encouraging evidence has emerged that a growing number of providers now recommend float therapy as a gentle way to support magnesium levels.

This isn’t just about absorption, though. The act of floating removes sensory distractions, creating space for the nervous system to shift out of high alert. It's an invitation into parasympathetic calm—the state where healing, digestion, and restoration can actually occur. This layered support is one reason floating may feel particularly soothing for those with magnesium deficiency symptoms.

Relief Beyond the Physical

Clients who float regularly often share stories of more restful sleep, fewer muscle spasms, improved mood, and a general sense of ease. Whether that’s from the mineral-rich water, the weightless stillness, or the nervous system reset—or all three—the result is the same: they feel better.

For those navigating the effects of stress, chronic tension, or just a longing to feel more at home in their bodies, float therapy offers a compassionate, non-invasive option. It's not a cure-all, and it shouldn't replace medical care when needed. But for many, it's a supportive ritual that helps restore balance, inside and out.

At Jax-Zen, we welcome you just as you are. If you’re curious about how floating might help you unwind, replenish, or simply breathe a little easier, we’re here to hold that space for you.

You don’t have to carry it all alone.
