The fact that there have been no peer-reviewed studies after some 70 years is a huge red flag. This is why talking about floating isn’t valid as continuing education for medical doctors. This is why float marketing feels like selling snake oil. Without peer review of research, this is just paying to sit in a large tub of lukewarm, salty water; any other claims made are specious and should be looked at with suspicion. I’m stunned that no serious research has ever been done.
