The Science behind Floatation Therapy: Reducing Brain Workload through Sensory Deprivation

Floatation Therapy is based on the intriguing theory that nearly 90% of the brain’s workload is attributed to the effects of external environmental stimuli, such as gravity, temperature, touch, light, and sound. Interestingly, even during sleep, the mind remains active by processing signals from various parts of the body that come into contact with the bed, covers, and changes in temperature, as well as auditory and gravitational cues. This is why floatation therapy, with its reduction in external stimuli, has been found to be a powerful tool for achieving deep relaxation and meditative states.

Meet the Team at Zero Gravity Float Spa

Simon Preedy 

Simon initially floated to wind down and sleep better, but he soon discovered it was also a powerful tool for self-development and meditation. He is passionate about sharing these benefits with others. Simon enjoys practicing Jiu Jitsu, yoga, running and hiking in the mountains.



Chris Henson

Chris initially turned to float therapy to relieve his back pain. As he started floating regularly, he noticed the tranquility he achieved during his sessions carried over into his everyday life. When he’s not floating, you’ll find Chris tinkering with his gaming PC or enjoying a good book.

Graeme Poston 

Retired surgeon Graeme developed chronic pain in his neck after nearly 40 years of standing bent over at the operating table. After Simon convinced him to try floating, Graeme’s neck was pain-free for several days. He now floats weekly and continues to benefit from the therapy.

Hannah O’Brien

Hannah is passionate about alternative methods to improve mental well-being and finding ‘me time.’ Floating provides her with the perfect opportunity to relax and switch off, as well as recover from long runs. When not floating, she enjoys running, hiking, and baking treats in the kitchen.


Anna Kaur

During her floats, Anna finds that meditating and practicing breathwork allow her to achieve a profound sense of bliss, which comes naturally to her as she was raised in a holistic family. Outside of her sessions, Anna can be found enjoying sailing, climbing, and learning new skills to expand her knowledge.
