Floatation Therapy and Its Ability to Replenish Lost Minerals. The Magic of Epsom Salt Baths and Magnesium.

Have you ever wondered what makes Epsom salt so different than other salts? Why do we use it in integrative wellness, and what does it have to offer? Especially after a long winter in NY, feeling like you've reached your daily values for minerals can feel like a challenge. Stress, poor sleep, processed foods, and daily demands can quietly deplete essential minerals that our bodies rely on to function properly. One mineral in particular stands out: magnesium.

Often called the “relaxation mineral,” magnesium plays a role in hundreds of biological processes. Yet research suggests that a large portion of the population does not get enough of it through diet alone. This is where floatation therapy offers something truly unique.

By floating effortlessly in a warm solution of highly concentrated Epsom salt (magnesium sulfate), the body is given an opportunity to rest, reset, and potentially replenish important minerals while the nervous system shifts into a deeply restorative state. For those of you wondering what the magic of Magnesium can provide for you, we wanted to dive into it!

What is Epsom salt and what's the difference?

Epsom salt or magnesium sulphate (MgSO₄) was discovered in Epsom, England and is a colorless white crystalline salt that is most noticeably sold as bath salt. With a distinct taste (bad) and different structure, purpose, and effect on the body than regular table salt, Epsom salt tends to lend its benefits in a more functional approach.

"While both are called “salt,” Epsom salt and table salt serve entirely different purposes. Table salt fuels the body through nutrition, while Epsom salt supports recovery and relaxation through magnesium-rich soaking—making it a cornerstone of floatation therapy."

Epsom Salt = Magnesium Sulfate (MgSO₄) Contains magnesium, a mineral your body needs for recovery, relaxation, and nervous system support

Table Salt = Sodium Chloride (NaCl) Contains sodium, which helps regulate fluid balance and nerve signaling

Purpose & Use

Epsom Salt Used in baths, floatation therapy, and wellness practices Supports relaxation, muscle recovery, and stress reduction Not typically used as food

Table Salt Used for cooking and seasoning Essential for bodily functions when consumed in proper amounts Not used for soaking or therapeutic recovery

How They Interact with the Body

Epsom Salt Dissolves in water and releases magnesium and sulfate May be absorbed through the skin during soaking Helps promote a parasympathetic (rest-and-recover) state

Table Salt Consumed through food and absorbed via digestion Helps maintain fluid balance, nerve function, and blood pressure Too much can contribute to dehydration or high blood pressure

Experience in Water

Epsom Salt (Floatation Therapy) Extremely high concentrations allow you to float effortlessly Creates a weightless, pressure-free environment Feels silky and buoyant

Table Salt (Ocean Water) Provides some buoyancy, but not nearly as much Feels more drying on the skin Not concentrated enough for true weightless floating

Why Magnesium Matters So Much

Magnesium is involved in more than 300 enzymatic reactions in the human body. It helps regulate:

• Muscle and nerve function

• Blood pressure

• Energy production

• Sleep cycles

• Stress response

• Inflammation

• Heart rhythm

When magnesium levels are low, people may experience:

• Muscle tension

• Fatigue

• Headaches

• Poor sleep

• Increased stress sensitivity

• Restlessness

• Brain fog

This is why replenishment matters.

And it is one of the reasons floatation therapy has become such a powerful wellness tool.

Can Magnesium Be Absorbed Through the Skin?

This is one of the most frequently asked questions and the science is evolving.

The skin is not simply a barrier. It is an active organ capable of absorbing certain substances under the right conditions.

Several studies have explored transdermal magnesium absorption, meaning absorption through the skin.

Research findings suggest:

• Magnesium levels in the body may increase after repeated exposure to magnesium-rich baths

• Warm water improves circulation and skin permeability

• Extended soaking times increase the likelihood of absorption

• Relaxation of the nervous system enhances mineral utilization

While scientists continue to study the exact mechanisms, many clinicians and researchers recognize that magnesium exposure through bathing may support overall magnesium balance, especially when combined with relaxation and reduced stress.

In floatation therapy, these conditions are optimized.

Why Floatation Therapy Is Different From a Regular Bath

Some people wonder:

“Can’t I just pour bags of Epsom salt into my bathtub?”

While home baths can certainly be beneficial, floatation therapy provides a dramatically different environment. Here’s why.

Much Higher Magnesium Concentration

A typical home bath may contain 2–4 cups of Epsom salt

A float room contains: Hundreds of pounds of Epsom salt

This creates:

• Extreme buoyancy

• Full body support

• Consistent mineral exposure

• Reduced pressure on joints and muscles

Optimal Water Temperature

Float rooms are maintained at approximately: Skin-neutral temperature (around 93–95°F)

This temperature:

• Encourages deep relaxation

• Reduces sensory input

• Improves circulation

• Supports nervous system regulation

Sensory Reduction and Nervous System Reset

One of the most powerful aspects of floating is not just the magnesium it's the environment.

Floatation therapy reduces:

• Gravity

• Light

• Noise

• Physical pressure

This allows the nervous system to shift from: Fight-or-flight to Rest-and-restore

When the nervous system calms, the body becomes more efficient at:

• Repairing tissue

• Balancing hormones

• Reducing inflammation

• Absorbing and utilizing nutrients

Including magnesium.

The Link Between Stress and Mineral Loss

Stress is one of the fastest ways to deplete magnesium. When the body experiences stress, it releases hormones like cortisol, and adrenaline. These hormones increase magnesium excretion through urine and sweat.

In other words: The more stressed we are, the faster we lose magnesium.

This creates a cycle. Stress→ Magnesium loss→ Increased tension→ Poor sleep→ More stress

Floatation therapy helps interrupt that cycle.

What People Often Notice After Floating Regularly

At The Float Place, many clients report changes that align with improved magnesium balance and nervous system regulation.

Common experiences include:

• Reduced muscle tension

• Better sleep

• Faster recovery after workouts

• Improved mood

• Less stress and anxiety

• Increased mental clarity

• Fewer headaches

• Greater sense of calm

While individual experiences vary, these outcomes are consistent with what research shows about relaxation, sensory reduction, and magnesium exposure.
