A sensory deprivation tank, also called an isolation tank or flotation tank, is used for restricted environmental stimulation therapy (REST). It is a dark, soundproof tank that is filled with a foot or less of saltwater.

Float pods originally started as sensory deprivation tanks in the mid-1950s, exploring how the absence of light, sound, touch, and other stimuli affects the mind and body. In recent years, multiple scientific studies on restricted environmental stimulation therapy in float pods (floatation REST) have yielded reams of data about the benefits to creativity, productivity, and both physical and mental health.

Inngi Float’s floatation pods use the latest scientific and design practices to deliver unique, relaxing experiences with a myriad of benefits to newcomers and enthusiasts alike.



From migraines to arthritis to backaches, pain can, unfortunately, come in all shapes and sizes. The good news is that floatation therapy offers relief to many kinds of pain: effortlessly floating with zero pressure on muscles and joints, supplemented by the stress reduction and enhanced sleep, can work wonders for relieving pain. Our frequent clients report these benefits of floating every day, but floating’s pain-relieving power is also supported by a sizable body of scientific research.

When we’re stressed, our muscles tense. It’s simply a fact—on a biological level, we have evolved to experience stress as a response to a threat to our safety. When our brains receive these stress signals, they prepare our bodies for fight or flight by producing higher levels of hormones like adrenaline and cortisol. Those hormones set off a chain of responses, like tensing our muscles and quickening our heart rate. But when the cause of our stress isn’t something we have to outrun or battle (which is usually the case in modern times), and that stress doesn’t dissipate quickly, we’re left with tense, achy muscles and discomfort.

That’s where floating can help. Physically, floating provides relief. Those achy muscles and tense joints can experience true relaxation in a float tank, enjoying zero pressure as you float effortlessly in highly concentrated saltwater.

In one study, people who floated for 12 sessions noticed decreased pain, stress, anxiety, and depression as well as improved sleep quality and general optimism. The results lasted up to four months post-flotation.

In a single-subject study, a 24-year-old diagnosed with autism, PTSD, anxiety, and depression participated in regular float sessions for one and a half years. She experienced beneficial therapeutic effects including improved quality of life, subjective sense of wellbeing, and healthier behaviors. The study quotes her stating: “I feel good, well, like a new person, and so it has made a great difference… It really has and I really want to continue with this because I really need it.”


Floating helps combat stress in several ways. First,  the water’s magnesium inhibits ACTH, a hormone that drives your adrenal glands to release the stress hormone cortisol.Magnesium also improves sleep quality, which contributes to feeling less stressed. In a recent study, people who floated eight times in two weeks saw their cortisol decrease by 21.6 percent.

3. Floating Enhances Physical Performance 

Floating helps you bounce back faster from workouts by reducing lactic acid in the blood. By floating fee of gravity, lactic acid passes out of the muscles faster, which reduces overall muscle stiffness and pain. Floating benefits extend to athletes on the field as well. One study on basketball players found strong evidence of athletic skill improvement post floating. These results may be due to a lower arousal state post floating, which enabled the players to maintain better focus while shooting foul shots.
