Whether you are just merely considering float therapy, are new to the practice, or have been enjoying sessions for many years, it is always good to examine why the sensory deprivation sessions work and what benefits it has for the body.

Float therapy takes place in a sensory deprivation tank. The tank blocks all light or sound from entering the space in order to block the senses. It is filled with 12” of a saltwater solution heated to about 95 degrees or the external temperature of the body. During the session, the participant floats freely within the solution in a completely effortless manner. The process rids them of stress, pain, and anxiety. The sensory deprivation combined with the free-floating weightless sensation allows the mind to enter a relaxed or meditative state because the body feels completely safe and secure. Sessions relieve many of the stressed brought on by normal day-to-day life, acting as a reset button for the brain.

The Epsom salts in the water keep the body floating without any effort, thus bringing a slew of physical and psychological effects. The purpose of this article is to focus on those psychological effects of float therapy.

How Stress Affects Your Overall Health

Stress is your body’s reaction to a particular situation, whether it is good or bad. The body releases chemicals into the bloodstream triggering a biological response to the situation. These chemicals do things like boost energy levels and strength, and they are your bodies natural defenses enabling you to cope with the situation at hand.

There are four main types of stress.

  1. Survival Stress: the good old “fight or flight” response animals have developed to deal with danger. Your body’s stress response will be either to run away or fight “the enemy.”
  2. Internal Stress: this is the self-inflicted kind of stress, the worrying for worrying’s sake type. It is often categorized as worrying about things you cannot control or are unlikely ever to come to pass.
  3. Environmental Stress: these stressors are found in your environment and can be something as simple as a loud, grating noise or as complex as a boss constantly looking over your shoulder.
  4. Fatigue and Overwork: this type of stress is slow-building, accumulating over months, but it can be the most damaging to your system because of the long-term and chronic nature of the stimulus.

There has been plenty of studies conducted on the tolls stress can take on the body, and the evidence is pretty plain. Stress is bad, it is bad for your physical health, and it is bad for your mental health. People under even moderate amounts of stress have trouble concentrating and are easily tired. Those under tremendous amounts of stress get sick more often, lose the ability to think clearly, and can even suffer from mental breakdowns.

Your brain is constantly working. It processes the near constant amount of stimuli going on around and within the body. It orients you to time and the space around you, but when you add in stressors, your brain has to work overtime. Many people today face unprecedented levels of stress on a near constant basis, and with all of that extra stimuli, it is easy to see how the brain can become overwhelmed. Once that happens, it enters a state of agitation or anxiety which is further exacerbated by the body dumping hormones into the system.

The psychological symptoms associated with stress vary by the level and length of time the brain and body are in overdrive. Acute stress generally sparks fear and/or anxiety in a person, while a more chronic stressful situation will lead to moodiness and irritability. Once a person reaches the adrenal fatigue stage, they may fall into a depression.

Stressful situations lead to worrying about stress which then causes the body to release more hormones. Those hormones lead to an increase in anxiety which ultimately leads to more stress. It becomes a vicious cycle which is why learning proper relaxation techniques are so important. This is where float therapy comes in.

Floating and the Brain

When you float, you are halfway submerged in the sensory deprivation chamber. It is dark, quiet, and warm. The act of floating is effortless because of the buoyancy of the magnesium sulfate solution, your body feels completely weightless, almost like being inside the womb.

There are no external stimuli for the brain to process, not even the need for your brain to keep your body oriented in time and place. Instead what happens, is that your brain gets its much-needed break for processing information. It is able to enter a state of deep relaxation.

A session in the chamber is a meditative state. You are essentially allowing your brain to calm itself by removing all stimuli which in turn soothes your body and decreases the flow of stress hormones into the bloodstream. Some people find that they are so relaxed they fall into a very peaceful sleep.

Float therapy helps your body enter into a state of homeostasis. The various body systems have a chance to reboot for optimal function. Think about it like restarting a computer!

Floating and Neurotransmitters

Neurotransmitters are chemical substances that are released at the tip of your nerve fibers due to electrical impulses sent by the brain. They diffuse across the synapses and transfer from one nerve fiber to the next. In other words, they are the chemical messengers from the brain that give the body instructions.

You are probably familiar with several neurotransmitters, even if you didn’t know what they were technically called. Most people have heard of serotonin, it is often called the happiness chemical, but in fact, it is actually responsible for many functions in the body including regulating the appetite and memory. Also, dopamine and epinephrine are commonly known neurotransmitters responsible for a number of functions.

Another benefit of float therapy is the addition of “good” neurotransmitters. Once the body reaches the relaxed state within the tank, the brain is able to quiet itself from the hyper-stressed state. It then begins to release endorphins and dopamine.

Endorphins interact with your brain’s pain receptors, easing the feeling of pain within the body. They also trigger a very positive feeling within the body, some have even compared the effect to a morphine high. Runners are known to have a euphoric feeling after a run which is attributed to endorphins.

Dopamine is a neurotransmitter that helps control the reward and the pleasure centers of the brain. Dopamine helps regulate your emotional responses but is generally associated with feeling good. It is one of the key ingredients in the neurotransmitter cocktail that makes up the feeling of love.

The increase of dopamine and endorphins in the body attained after a sensory deprivation session provides the participant with a sense of wellbeing. It has also been shown to have other benefits as well. After just a few sessions, participants have shown improvement in memory function, and their performance levels have increased.

Combating Anxiety with Float Therapy

Anxiety is actually a general term. It encompasses a wide array of disorders that cause nervousness, fear, apprehension, and worrying. Anxiety disorders can be brought on by many factors, many physiological, but it can also be caused by stress, especially internal stress.

Float therapy can be used to help combat stress in the system, no matter the form or cause. Participants with PTSD, depression, OCD, and/or panic attacks have all seen improvements in their conditions with floating.

Don’t Let Float Therapy be one of the Causes of your Stress

It is common for people interested in trying float therapy for the first time to have some misgivings about the process and all it entails. They may be concerned about being enclosed in the sensory deprivation tank, especially if they have claustrophobia. They may be concerned that their anxiety levels won’t allow them to relax and gain from the experience. If they have PTSD, they may be concerned that the tank will send them into flashbacks or nightmares.

However, research has shown that the potential for easing the disorders far outweighs the initial anxiety, and most people find they have no problem being in the tank even with a diagnosed anxiety disorder.

The International Journal of Stress Management published a study recently about the benefits of float therapy. The study found that in a group of 70 people, the symptoms related to anxiety, stress, depression, and even chronic pain lessened significantly after taking a course of 12 sessions. Plus, for some participants, the effects lasted for four months after the final float session.

In the not too distant past, float therapy was seen as just a hippie fad. Sensory deprivation was relegated to the realms of pseudoscience and wasn’t to be taken seriously. However, that is no longer the case. As more and more studies show proven benefits, and more people are coming to understand the process, it is becoming so much more than just another homeopathic remedy in the eyes of the health community.

From helping people deal with chronic stress and its devastating effects on the body to helping PTSD patients manage their symptoms so well they are able to go off of medication, float therapy has proven itself as a beneficial tool for mental health professionals to keep in their arsenal. It is another proven way to help mend the mind and the body without the use of side-effect riddled medications.

In fact, beyond the much-touted health benefits for the body, there are also psychological effects that are just as important.

Stress and Overall Health

There has already been plenty of evidence presented for the ill effects of stress on the body. However, in order to understand the psychological effects of floating, you have to understand the relationship between the brain and stress. Your brain is constantly working to process the constant stimuli going on around you and to orient your body in the space around you. When you add in the constant stress that many face today, it is easy to see how the brain becomes overwhelmed and enters a state of near agitation. When you add in the increased levels of stress hormones and their effects on the brain and body, it is easy to see why relaxation is so important.

Floating and the Brain

When you float, you are in a chamber or tank that is dark and quiet. There are no external stimuli – including the need for your brain to focus on keeping your body oriented. Instead, your brain can actually rest from processing information, allowing it to enter a state of deep relaxation. In this meditative state, you essentially allow your brain to calm itself and your body – all while lowering the amount stress hormones in your system. Floating also helps your body to enter a state of homeostasis, wherein the different systems throughout your body have a chance to reset for optimal function.

Floating and Neurotransmitters

Another important benefit of floating and the state of relaxation that is induces is that it causes the brain to release endorphins and dopamine, which are neurotransmitters that help the body to naturally feel good. The increased levels of these neurotransmitters provides an improved sense of wellbeing, along with plenty of other benefits that include better memory and increased performance levels.


There are likely many who are interested in the idea of float therapy, but are simply too concerned with the possibility for it to induce anxiety – especially in those with claustrophobia. Mental disorders such as anxiety, Post-Traumatic Stress Disorder (PTSD) and claustrophobia can all prevent sufferers from trying that first float therapy session. The reality is, however, that research is currently ongoing that is showing the potential for an easing of symptoms of these disorders with float therapy.

A study published in the International Journal of Stress Management found that in a group that consisted of 70 people, their symptoms of anxiety, stress, depression and even pain lessened after 12 sessions. These effects were also found to last for up to four months after the final float session.

Floating was once relegated to the side of hippie fads, but more and more people are understanding that it is something so much more. From helping people deal with chronic stress and its effects on the body to anxiety and PTSD, floating is proving itself as a beneficial tool for those who want to heal their bodies and their minds – without the use of medications.

While research is still in progress, no one has to wait to start benefitting from the effects of floating on the mind and body. Contact us today or make your appointment to get started with the ultimate in relaxation.
