My first flotation experience yesterday was so interesting, a quick check-in on FB just didn’t do it justice. A friend suggested I join her for my first flotation session at Floathouse in Gastown last night, a twist on Saturday happy hour activities. I’ve seen quite a few flotation places opening up and heard little snippets about it, but didn’t know anyone who had actually tried it. Being shut inside a sensory deprivation tank, floating in super saturated water for an hour and a half . . . hmmm, well that sounds . . . interesting. Not without a certain degree of anxiety (how big is this tank?) and because I’m usually pretty good at saying yes first and considering the consequences later . . .I said sure, I’m in!
What is flotation? It’s a currently en vogue form of sensory deprivation with big health benefits flowing from the state of deep relaxation and meditation. While not a formal practitioner of meditation, I’ve long enjoyed the deep relaxation and sometimes profound moments that come from the meditative process in yoga, hot yoga in particular has always been deeply meditative for me. If I could overcome the thought of being shut inside this little dark tank for 90 minutes (would I be claustrophobic? bored? cold?) this might be kinda cool. If you want to know more details, check out the video below.
Each room is self-contained with shower, towels and everything you need. I got naked, coz that’s how you float, took a cool, scent free shower (reduce all sensory input) and climbed into the tank. 10 inches of skin temperature water with about 900 lbs of epsom salts – yes, 900lbs – several times more saturated than the Dead Sea.
I took the good advice on my first time to sit comfortably at the door and practice opening and closing it a few times to be comfortable with total darkness and finding the damn handle if I panicked. So far so good. Next step, lie down and start to float, which you do effortlessly. I forgot the next piece of advice, which was to keep my hands on the sides until the water stopped moving. With the complete absence of light or sense of gravity to cue spatial orientation, the movement of the water as I lay down made me feel slightly motion sick, or that I was somehow falling forward. Strange, but with absolutely nothing to cue me my body to it’s alignment I felt like I was tipping forward. If you’ve scuba dived at night or in dark conditions, you will have some idea of the complete spatial disorientation of being in a weightless, gravity free, three dimensional world.
The water motion stopped and I just lay there, trying to relax wondering if I would sink. My skin temperature and the water temperature matched perfectly and soon it was hard to tell where my body ended and the water started. I chose a 30 minute guided meditation for my first time, it was a great choice. A basic savasana progressively relaxing from toes to scalp.
Thoughts and some very vivid images came and went, I don’t recall when the guided meditation ended and it got very quiet and there were a few moments when thoughts brought me back to the present, but all sense of time disappeared. It felt like 10 minutes later I heard more gentle music and was completely unbelieving that 90 minutes had gone by. It took several minutes to reorient myself to the physical presence of my body and conscious thought and movement in my profoundly relaxed brain. I had to check my watch when I got out to convince myself that 90 minutes really had gone by!
So what happened that made time cease to exist for me? Current research says that we have four major types of brain waves or activity.
- Beta – the waking rythmn – that’s when we are awake and going through our daily lives
- Alpha waves are slower, we are awake but calm and relaxed, often with eyes closed.
- Theta – as the brain calms and slows we experience these slow, powerful, rhythmic waves. Everyone generates theta waves at least twice a day as we drift from conscious drowsiness into sleep and again when we move from sleep to consciousness when we wake up. If we have the luxury of not being instantly wakened by alarms, children . . you know, life, we can experience unexpected, unpredictable, dreamlike but very vivid mental images (known as the hypnagogic images ) and intense memories. It’s hard to maintain, since we tend to fall asleep as soon as soon as we begin generating large amounts of theta.
- Delta – extremely slow, low frequency brain waves usually generated when we are asleep or unconscious.
The deep meditative state we can enter during the profound sensory deprivation of floatation allow our brains to slow down enough to remain in a theta wave generating state for extended periods of time. It was, quite simply, incredible. When I got out of the tank I knew I hadn’t been asleep or unconscious, but I also couldn’t explain where “I” had been during that time. A profound, and profoundly calming and restorative experience. A few of the images have remained with me, as the everyday busyness and sensory overload of daily life dropped away, crystal clear, full colour images and memories resurfaced.
Once out of the tank you have to shower and wash your hair to get rid of the salt and it took me a while to recover my spatial orientation – that usually unnoticed sense of where our physical bodies are located in space – I had kept tipping over in the shower. And then it’s recommended to spend some time in the lounge rehydrating and getting back in touch with the world before stepping out the door. I had a long chat with one of the employees and he explained the Theta wave state! How did I feel after? Energized, it was like I’d had a long, refreshing nap, without the sleepy hangover feeling. And I slept deeply and profoundly for 8 straight hours last night and woke up relaxed and refreshed. I’m a convert to benefits of flotation.
- Don’t rub your eyes or touch your face in the tank – salt stings like heck and you’ll have to get out and wash your eyes! Same for shaving or waxing . . . just saying.
- Remember a hairbrush, elastics etc if you have a long shaggy mane like me. Chrome domes, you got nothing to worry about.
- I wondered if my skin would feel dry and nasty from the salt, but it doesn’t, just clean and soft.
- Leave enough time after to relax in the lounge and reorient yourself to the outside world.
