The Magnesium-Rich Water You Float In — And Why It Matters

There's something quietly remarkable about the water inside an Ultrafloat pod.

It's not ordinary water. Each float pod contains around 500 kilograms of dissolved Epsom salt — magnesium sulphate — creating a solution so dense that your body floats effortlessly on the surface. No effort. No paddling. Just stillness.

But beyond the buoyancy, there's a reason magnesium keeps coming up in conversations about recovery, sleep, and stress. And it's worth understanding why.

What Is Magnesium, and Why Do We Care?

Magnesium is one of the most abundant minerals in the human body. It plays a role in hundreds of enzymatic processes — everything from energy metabolism to muscle function to nervous system regulation.

The challenge? Most people don't get enough of it.

Modern diets are often low in magnesium-rich foods like dark leafy greens, nuts, seeds, and legumes. Add to that the fact that chronic stress depletes magnesium stores, and you start to see why so many people walk around running on empty — tense, wired, struggling to switch off.

The Float Tank and Magnesium

When you float in an Ultrafloat pod, your skin is in contact with a highly concentrated magnesium sulphate solution for 60 minutes.

There is growing interest in whether magnesium can be absorbed transdermally — through the skin — during bathing or soaking. While research in this area is still developing, what is well established is that many people report feeling deeply relaxed after a float session.

Whether that's the result of magnesium, the sensory deprivation environment, the removal of gravitational load, or simply having uninterrupted stillness — the outcome speaks for itself.

What the Float Environment Actually Does

The float tank is designed to remove input.

No light. No sound. No pressure on your joints. No notifications. No demands.

Your nervous system — which is constantly processing, filtering, and responding to the world around you — gets a rare window to quiet down. For many people, this is profoundly unfamiliar. And profoundly valuable.

The combination of the magnesium-rich water and the sensory-reduced environment creates conditions that most of us rarely — if ever — experience in daily life.

Who Floats at Ultrafloat?

Our members come from all walks of life. Athletes who want to support their recovery. Professionals dealing with high cognitive load. People who simply struggle to switch off. Parents who haven't had silence in months.

What they share is an understanding that genuine rest isn't a luxury — it's a foundation.

The float pod doesn't fix anything. It creates the conditions for your body and mind to do what they were designed to do: restore, recalibrate, and reset.
