Floating and creativity

Peter Gabriel, the musical legend, says, “[My isolation tank] was quite useful, in the sense that you could get into a dream state, and I think that did allow…different thoughts and pictures to come through.

Joe Rogan, the comic and MMA host, says, “The sensory deprivation chamber is the most important tool I’ve ever used for developing my mind, for thinking, for evolving.

Matt Stangel of the Portland Mercury reports that after floating, “I began to write creatively for the first time in months, but with an uninhibited ease that I haven’t experienced in almost five years. In short, I was astounded by the changes I saw in myself.

What’s going on here? Why does everyone seem to come out of the tank talking about peace, clarity, and cosmic oneness, or “colors — of cars, of buildings, of the sky — [being] more lush“, or achieving “profound, ecstatic nothingness“, or even “like a DJ had showed up to the party and started remix­ing my brain“? People seem convinced the tank increases their creativity, but does it really, or are they just tripping?

Floating and sleep

One of the most common causes of insomnia is simple stress.  And loss of sleep not only makes it harder to deal with the outside stress in your life, but it is itself stressful.  It’s a vicious circle.

There are well-known remedies, but most have equally well-known drawbacks. Most drugs are actively habit-forming, or at least have diminishing returns if you rely on them.  Meditation can be very powerful, but requires disciplined practice and focus to achieve, practice that becomes harder to do when stressed out and short on sleep.

Simply taking 90 min to stop and float, though, can help you break the vicious cycle.  It triggers your relaxation response physiologically, so there’s no need for you to summon concentration when your brain is out of resources.  And astonishingly, it actually shows increased effect with repetition.

Floating and stress-related pain

One of the benefits you’ll most often hear claimed for float tanks is their powerful relaxing effect. Subjectively, people use descriptions like “I felt more rested than if I’d slept for 16 hours on a pile of tranquilized chinchillas,” or “the way you phys­i­cally feel after­wards is like get­ting a mas­sage, doing a full work­out, and get­ting 8 hours of sleep all at once”.

Many scientific studies have attempted to quantify this effect.  Does it have measurable biochemical effects? Does everyone experience it? If a person has tension headaches, for instance, does this relaxation effect actually help them? And if so, how long does the effect last?

One study done recently in Sweden says the answer is yes, and the effects seem to last for months.

Floating and fibromyalgia

Fibromyalgia is a disorder characterized by widespread musculoskeletal pain, described as a constant dull ache, typically arising from muscles. It effects 2% of general population and women are much more likely to develop it than are men by a ratio of 9:1.

Sufferers can be chronically tired, bedridden much of the time and suffer pain that feels like body-wide bruising. It can hurt even to be touched by another person. Restful sleep is difficult.  Many people who have fibromyalgia also have tension headaches, temporomandibular joint (TMJ) disorders, irritable bowel syndrome, anxiety and depression.

Fibromyalgia is not well understood at all. It can develop gradually, or have a sudden onset triggered by a traumatic event like a car accident. Its cause is not known. The best current explanation of what happens is that somehow the sufferer’s brain simply becomes more sensitive to pain (“central augmentation of pain sensitivity”), but how or why that happens is more or less anyone’s guess.

[UPDATE!  New research suggests fibromyalgia may actually be a problem with blood vessels in the skin.]

Science and sensory deprivation

Scientific study of sensory deprivation dates back almost sixty years, to the mid 50s, and float tanks as we know them today date back to the mid 60s. They’ve never been mainstream, but they were invented and developed in research settings, and the literature on them is reasonably extensive. In the scientific community, the field is known as “flotation REST”, for Restricted Environmental Stimulation Technique, or Therapy.

What has been found?  I’m still digging into it myself, but one survey I found lists:

  • reduced stress (Kjellgren, Sundequist, Norlander, & Archer, 2001),
  • reduced tension and anxiety (Fine & Turner, 1982; Schulz & Kaspar, 1994; Suedfeld, 1983),
  • reduced blood pressure (Fine & Turner, 1982; Turner, Fine, Ewy, & Sershon, 1989),
  • less muscle tension (Norlander, Bergman, & Archer, 1999)
  • increased well-being (Mahoney, 1990),
  • improved sleep (Ballard, 1993),
  • mild euphoria (Schulz & Kaspar, 1994),
  • increased originality (Forgays & Forgays, 1992; Norlander, Bergman, & Archer, 1998; Norlander, Kjellgren, & Archer, 2003; Sandlund, Linnarud, & Norlander, 2001; Suedfeld, Metcalfe, & Bluck, 1987), and
  • indications that the technique is a suitable complement to psycho-therapy (Jessen, 1990; Mahoney, 1990).
