Float Therapy: A 900-Pound Solution for Sleep and Anxiety
Operators in Portland report that the high-density magnesium baths are helping clients manage pain and stress.

A specific type of sensory deprivation therapy is gaining traction among individuals seeking relief from chronic pain and sleep disorders. The treatment involves submerging the body in a solution heavy enough to eliminate the sensation of gravity. Recent studies cited by industry practitioners indicate that this method can improve sleep quality and reduce physical pain.
The process requires lying in a tank filled with skin-temperature water containing nearly 1,000 pounds of dissolved magnesium. This high concentration creates a dense solution that prevents the body from sinking. Standard sessions last for at least one hour. Participants often choose to block out all light and sound to enhance the experience of weightlessness.
Nia Linbravo, who referees women’s basketball games four to five nights per week, began using the therapy after suffering from a herniated disk. Her schedule also includes work as a juvenile probation officer and project manager, roles that left her with little time to rest. Linbravo stated that the physical and mental demands made it difficult for her to relax. She consulted with her doctor about adding float therapy to her routine for managing depression and anxiety. Her physician advised that it would be helpful, a claim Linbravo has found to be accurate.
Dana Highfill has operated as a massage therapist for 17 years and currently runs Float North in Northeast Portland. She notes that most clients arrive seeking physical relief. Highfill explains that the buoyancy allows joints to open up, which can help reduce inflammation. She describes the experience as turning off gravity. The reduced stimulation to the nervous system helps shift the body from a fight-or-flight state to a rest-and-repair mode.
Linbravo describes the floating sensation as a form of mental release. She said the weightlessness allows her to reflect on her life and calm her mind. "I think it’s the weightlessness and the feeling of the water supporting me, and I’m literally just letting go," she said. She views the tank as a private space to talk to herself and be present in the moment.
Highfill addresses a common misconception that the tanks are small or confining. The facility uses single tanks that measure eight feet long and four feet wide. The interior ceiling height is seven feet. The water depth is approximately 10 inches, providing enough space for the body to float freely while maintaining the necessary density.
