Benefits of Flotation

What is floating?

Our tanks are filled with 900 lbs of dissolved, pharmaceutical-grade Epsom salt and purified water.

By having you float in tanks of silky, skin-temperature water, saturated with the purest quality salt, Salt Spa Saint Augustine offers the ultimate relaxation experience. For maximum comfort, our tanks are located in private rooms equipped with a shower.

Floating is a perfectly calming experience, having no contact points, no movement, and no postural muscle action. You will be fully supported and expend no physical energy to maintain your position in the water. The tank lid may be closed for the full experience, or it can be left open for your comfort. The water is kept at a constant temperature of 95 degrees, which feels warm at first, but soon becomes almost imperceptible. The line between the air and the water becomes blurred.

For your protection, the water in the float tank is completely filtered 5 times through a high-tech filtration system following each float session. The cleaning process includes 1 micron filtration, germicidal UV lamps, and an advanced oxidation process, making the water more sanitary than any swimming pool or hot tub. We are regulated by Florida Health Department as a public pool.

Relaxation Response

The tank suppresses the functioning of the sympathetic nervous system which, when active, produces our fight or flight response. It then activates the parasympathetic nervous system, which is responsible for relaxation, healing, replenishment, etc. Physical symptoms of the relaxation response include decreased muscle tension, blood pressure, and stress hormones, and increased endorphins. The deep relaxation provided by flotation remedies sore muscles by reducing the production of lactic acid, and increasing the production of beta endorphins.

Heightened Senses

Research indicates increased visual acuity, improved tactile perception, improved auditory sensitivity, and increased taste sensitivities after floating.

Pain Management

Arthritis, back pain, neck pain, tendinitis, bursitis, inflammation, and psychosomatic pain relief have all been documented via tank use.

Increased Immune Function

Immune function is enhanced by suppressing stress hormones which not only weaken the immune system but also suppress the digestion and reproductive systems, affect regeneration processes, and decrease insulin sensitivity.

Enhanced healing/rejuvenation/recovery

Floating increases circulation to extremities, promotes greater elimination of metabolic by products, decreases the forces of gravity to help promote greater muscular relaxation, and it can prevent adrenal fatigue.

Musculoskeletal Awareness

Floating decreases chronic muscle tension and creates greater awareness of less noticeable areas of muscle tension and imbalances.

Anti-gravity Benefits

Although floating is not zero-gravity (like outer space), the density of the salt solution does create the maximal amount of the forces of gravity to be dispersed across the greatest surface area of the body. Rigid postures and chronic muscular tension from daily life can cause ailments such as lower-back pain, neck pain, shallow breathing, high blood pressure, etc. The anti-gravity environment of the float tank disperses forces to the smallest amount and thus decreases the source of gravity-related stimulation to the minimum possible value providing relief to these specific areas.

Increased Stress Resistance

Regular floating can alter the set-points in the endocrine homeostatic mechanism which can cause adjustments such as a lower adrenal activation threshold. This means that we become more resistant to the stimuli of chronic stressors bombarding us in modern urban settings and lifestyles and literally develop a higher physiological threshold to deal with stress. The state of deep relaxation regulates our breathing and our blood circulation, allowing for extraordinary healing effects through the absence of gravity.


Floating is a phenomenal tool to cultivate mental stillness. It often generates a sensation of being intensely awake yet extremely relaxed. It can induce theta-state brainwaves and allows for one to remain conscious in this frequency instead of falling asleep. Floating may induce an altered state of consciousness, especially when done repeatedly.

Chronic Stress Relief

The tanks environment eliminates as much external input as possible, letting your nervous system have a break. In a life filled with a constant buzz or hum, our systems rarely experience the isolation and silence that the tank’s environment provides. This experience can be very refreshing, nourishing and healthy for our bodies and minds. We are well-adapted for acute stress, but not for the chronic, constant stressors of modern life, which have been cited to be a cause of several forms of disease.

Behavior Modification

Floating is a great way to bring greater awareness to various patterns of behavior. Floating has demonstrated beneficial effects such as decreased anxiety and depression; increased calmness or sense of well-being; as well as fantastic results towards anti-smoking assistance and positive effects on weight-loss programs.

Brain Synchronization

Research has shown that the floating experience improves hemisphere synchronization, which promotes greater communication between the right (creative-side) and left (analytical-side) lobes; the majority of people are left-dominated. Also, people experience increased vertical communication between the primitive reptilian brain, the limbic middle or mammalian brain, and the conscious neocortex. These synchronizing reactions can cause elevated states of creativity, greater non-linear connections, and deeper realizations.


Being simultaneously extremely relaxed and intensely awake allows techniques of visualization to become very powerful. From athletes preparing for competition, to public speakers rehearsing a presentation, to students preparing for exams, the tank can induce the calm needed to perform at one’s best. Mental rehearsal research has shown it to be just as practical as physical rehearsal.

Sensitivity Buffering

Some of us are known as introverts while others are extroverts. Introverts who float can gain a feeling of safety and security; they often enjoy the break from constant stimulation they are usually hypersensitive to. No person or thing will disturb you while in the tank. Extroverts, conversely, can develop greater internal sensitivity from floating. They tend to seek extra stimulation and, paradoxically, through depriving the senses, the nervous system’s response is to turn up the volume to try and feel more. Because minimal input is coming in, they are able to develop greater sensitivity to their internal reality, and over time, their senses will become heightened, so they may not feel the need to be constantly stimulated.


Because floating can help manage chronic stress, facilitate introspection, and identify various less-serving modes of thinking, many people report drastically improved sleeping abilities. If sleeping is an issue, the change in your physical state and your mental outlook may provide you with a healthier perspective in which to put your body and mind to rest much easier each night. 90 minutes in the tank can feel like 6-8 hours of sleep. It is extremely therapeutic, refreshing and rejuvenating, and can help make up for any lack of sleep you may be experiencing.

Improved problem-solving

The Theta state allows for extremely deep relaxation both physically and mentally.

Floating and Magnesium 

Flotation Therapy is the amazing process of relaxing the body and mind in an anti-gravity, zero-distraction environment. Our float tanks are filled with 900+ pounds of Epsom salt (magnesium sulfate) and dissolved into approximately 150 gallons of purified water. This creates a very dense solution which allows the body to float effortlessly. The float guest has a choice of turning off the lights, music, and closing the pod lid which reveals another layer of deep tranquility and stillness. With the body fully supported, you are able to fully relax, let go and many of our guests even enter a theta brain wave state when floating. This is the same state associated with deep mediation, creativity and dreaming. So why is floating in Epsom salt ( magnesium sulfate) so beneficial? Did you know that there’s one nutrient in your body, and only one, that it’s deficiency is connected to 56 different diseases? Next to water and oxygen, your body needs magnesium to survive. Low Magnesium levels are rarely tested in most of the population so deficiencies go easily unnoticed. Magnesium deficiency can include anxiety, acid reflux, constipation, insomnia (Sleep), kidney stones and hormonal imbalances.

Magnesium alone…

➔ Balances calcium by dissolving it faster and making it more available for your teeth and bones…

➔ Is vital for over 1000 different chemical processes inside your body…

➔ Protects against Alzheimer’s, bone loss, diabetes and even cancer.

➔ Improves sleep and prevents dehydration

Floating is a great way for the body to absorb magnesium. According to a study, magnesium levels in the blood rise for a few days, and sulfate levels rise for 7 days, then level off. Many Americans are deficient in magnesium. Raising your magnesium levels can improve your circulation, improve your body’s ability to use insulin, ease muscle pain, regulate electrolytes, and relieve stress.  According to the Universal Health Institute: Although magnesium can be absorbed through the digestive tract, many foods, drugs and medical conditions can interfere with the effectiveness of this delivery method. Therefore, soaking in an Epsom Salt saturated water is one of the most effective means of making the magnesium your body needs readily available.
