If you've ever floated—or even just dipped your toes in Epsom salts—you may have heard that magnesium plays a big role in the benefits of float therapy. But what does that really mean for your body? And why is soaking in magnesium-rich water such a game changer for stress, sleep, and pain relief?
Let’s break it down in simple terms.
🛁 What Is Float Therapy?
Float therapy involves lying effortlessly in a warm, shallow pool of water that’s saturated with Epsom salt—over 1,000 pounds of it! The water is heated to skin temperature and kept completely still, quiet, and dark. Because the salt concentration is so high, you float like a cork with no effort.
But here’s where it gets really interesting: Epsom salt isn’t just salt—it’s magnesium sulfate, and it’s one of the key reasons float therapy is so effective.
💪 Why Is Magnesium Important?
Magnesium is a mineral your body absolutely needs, but most of us aren’t getting enough. In fact, it’s estimated that over half of U.S. adults are magnesium deficient. This matters because magnesium helps regulate:
Muscle function (including preventing cramps and spasms)
Nerve activity
Sleep and relaxation
Stress hormone levels (like cortisol)
Energy production
Inflammation
Without enough magnesium, your body and mind can feel tense, restless, and worn out.
🌊 How Float Therapy Delivers Magnesium
During a float session, your skin absorbs magnesium from the Epsom salt-rich water. Think of it like a sponge soaking in a warm mineral bath. While your body relaxes in the zero-gravity environment, the magnesium works its way in through your skin.
This is called transdermal absorption, and it’s a great way to supplement magnesium levels—especially if your digestive system doesn’t absorb oral magnesium supplements well.
🧠 What You’ll Feel
People often report these benefits after floating:
Looser muscles and less pain
A calm, “reset” nervous system
Better sleep that night
Mental clarity and emotional balance
Less anxiety or racing thoughts
That’s the magnesium (plus the peaceful environment) at work—relaxing both your body and brain.
🌿 Float Therapy: Nature’s Chill Pill
Floating isn’t just about unplugging from the outside world. It’s about recharging your body with one of nature’s most powerful minerals.
By delivering magnesium directly through your skin while also removing pressure, sound, and light, float therapy offers the perfect storm for deep, natural healing.
