We live in a world filled with distractions, noise, and constant demands on our attention. Many of us find ourselves yearning for moments of tranquility and inner peace. Our souls seek refuge in activities that allow us to disconnect from the chaos of everyday life and reconnect with our inner selves.
In these quiet moments, where we can truly listen to our thoughts and feelings, we find solace and relief from the relentless pressures of modern living. Float tank therapy offers a unique and transformative experience to achieve this.
This comprehensive guide will dive deep into the float tank experience. We’ll explore its mechanics and benefits on our physical, emotional, and spiritual well-being.
What is a Float Tank?
A float tank, also known as a sensory deprivation or isolation tank, is an enclosed chamber meticulously designed to minimize sensory input. The structure measures approximately 8 feet in length, 5 feet in width, and 4.5 feet in height. That’s ample room for users to stretch out and move without feeling confined.
Within the chamber lies approximately 10 inches of water saturated with Epsom salt – nearly 1,000 pounds of it! The density of the saline solution allows individuals to float effortlessly on the surface without any exertion. To further eliminate tactile distractions, the water is heated to skin temperature. Doing so blurs the boundary between one’s body and the surrounding fluid.
To ensure a complete sensory deprivation experience, the interior of the float tank remains pitch black when sealed shut. Newer models may feature customizable lighting options for those who prefer a more gradual transition into total darkness.
The Evolution of Float Tanks
As our understanding of the human mind and consciousness has expanded, so too has the design and application of float tanks. The origins of sensory deprivation can be traced back to the 1950s. Neuroscientist John C. Lilly was the first to experiment with the effects of isolation tanks.
Lilly was also somewhat of a psychonaut. He sought to explore the depths of human consciousness by isolating it from external stimuli. In 1954, he created the world’s first float tank, though it was a rudimentary version of what we have today.
The early iterations of float tanks were cumbersome. They often required users to wear uncomfortable masks or submerge themselves in a more confined environment. Over time, float tanks have transformed from basic chambers to sophisticated sanctuaries.
How Does a Float Tank Work?
Picture yourself floating in a tranquil space devoid of sound, light, and external stimuli. As you surrender to the embrace of the water, your thoughts begin to dissipate, and you experience a profound sense of peace and relaxation.
This is the essence of the float tank experience. You effortlessly float in a warm embrace of water that feels like an extension of your own body. Some people compare it to being back in the womb.
As the chamber envelops you in darkness and silence, your mind is freed from external distractions. This grants you the opportunity to journey inward. You’ll explore thoughts, emotions, and sensations unencumbered by daily life.
The Sensory Deprivation Experience

Float tank sessions offer a powerful and immersive sensory deprivation experience. Sensory deprivation is the intentional reduction or elimination of external stimuli to one’s senses. Through this practice, individuals create a unique opportunity for their minds to explore internal landscapes uninhibited by distractions from the outside world.
Once your senses are deprived of their usual input, your brain is freed from its constant vigilance. This allows it to delve into deeper levels of consciousness. In this space, you may encounter vivid mental imagery or heightened intuition. You may even experience moments of transcendence. The boundaries between self and the surrounding environment will seem to dissolve.
The beauty of the experience lies in its ability to facilitate an intimate encounter with your innermost self. Not unlike psychedelic experiences, sensory deprivation can induce profound shifts in perception. However, they differ in terms of mechanism since psychedelic substances directly interact with specific neurotransmitters within the brain.
Another key distinction lies in the level of control individuals possess during the experiences. In a float tank session, users can exit the tank anytime should they feel overwhelmed or uncomfortable. On the other hand, once a psychedelic substance has been ingested, its effects persist until the body has metabolized it.
What Are The Benefits of Float Tank Therapy: A Brief Overview
Float tank therapy has garnered significant attention in recent years. A growing body of scientific research highlights its potential benefits for physical and mental well-being. Studies have demonstrated that sensory deprivation can contribute to the following:
- Stress reduction
- Pain relief
- Sleep improvement
- Enhanced cognitive function
Several theories have been proposed to explain the benefits associated with float tank therapy.
1. The Anti-Gravity Theory – This theory suggests that the weightless environment in a float tank relieves pressure on joints, muscles, and bones. We are constantly bombarded by thousands of pounds of pressure from the earth’s gravity, so in a weightless environment, our bodies can relax.
2. The Brain Wave Theory – According to this theory, the sensory deprivation experienced during a float session induces changes in brainwave activity. Specifically, it increases theta wave production. Theta waves are associated with deep relaxation, meditation, and enhanced creativity. That may contribute to the mental clarity and problem-solving abilities reported by float tank users.
3. The Left-Brain Right-Brain Theory – This theory posits that sensory deprivation helps balance the activity between the left (logical) and right (creative) hemispheres of the brain. By reducing external stimuli, both sides of the brain can work together more harmoniously.
4. The Biochemical Theory – Sensory deprivation has been shown to reduce cortisol levels. That’s the hormone released in response to stress. It also increases endorphins and other feel-good chemicals within the body. This shift in biochemistry may contribute to improved mood, anxiety reduction, and an overall sense of well-being.
5. The Biofeedback Theory – Float tanks provide an environment conducive to self-awareness and introspection. It allows individuals to become more attuned to their own physiological responses. Users may develop greater control over their autonomic nervous system by tuning into their bodies’ signals (such as heart rate or breathing patterns).
More research is needed to understand the mechanisms underlying these benefits fully. But float tank therapy holds immense potential for enhancing overall health and wellness.
Insights from Float Tank Enthusiasts and Experts
Float tank therapy’s growing popularity has led to many anecdotal reports about the experience. Plenty of these can be found online, including on forums and social media. It has become somewhat of a lifestyle where “floating” is the main activity. Individuals have float sessions regularly as part of their wellness regimen.
Mental health professionals and researchers alike have also recognized the potential benefits. Float tank therapy addresses psychological issues such as anxiety, PTSD, and sleep disorders. One of the most popular is Dr. Justin Feinstein, a clinical neuropsychologist and director of the Laureate Institute for Brain Research. He has conducted numerous studies on float therapy’s impact on mental health, demonstrating its effectiveness.
Float tank pioneers, such as John C. Lilly and psychologist Dr. Peter Suedfeld, have extensively researched its applications in treating various mental health issues. Dr. Roderick Borrie, another clinical psychologist and researcher, is also known for his work on floatation-REST (Reduced Environmental Stimulation Therapy). In conjunction with traditional psychotherapy, it helps individuals struggling with anxiety and depression.

Practical Tips for Those Interested in Trying a Float Tank Session
If you are considering trying float tank therapy for the first time, preparing for the experience is crucial. The following practical tips will help you get the most out of your float session and maximize its benefits:
1. Hygiene – Ensure you shower thoroughly before entering the float tank. You want to maintain a clean environment for both yourself and future users. Most float centers provide showers and toiletries on-site for your convenience.
2. Clothing – It is recommended to float nude to experience sensory deprivation without the distraction of clothing. However, if you feel more comfortable wearing a bathing suit, opt for something minimal and non-restrictive.
3. Foods and Drinks – Avoid consuming caffeine or heavy meals prior to your float session, as they may interfere with your ability to relax fully. Aim to have a light snack an hour or two before your appointment to prevent hunger pangs during the session.
4. Pre-Float Rituals – Engage in activities that promote relaxation before entering the float tank. Some people try meditation, gentle stretching, deep breathing exercises, or setting positive intentions for their experience.
5. Positioning – Experiment with different body positions within the tank to find what feels most comfortable for you. Some individuals prefer arms at their sides, while others may choose to place their hands behind their heads.
6. Transitioning Back – After your session, take some time to sit quietly and reflect on your experience before reintegrating into your surroundings. Consider journaling about your insights or sharing them with someone who understands the significance of sensory deprivation therapy.
Incorporating Float Tank Therapy Into a Wellness Routine
Float tank therapy can be a powerful addition to your overall wellness routine when combined with other health-promoting practices.
