Life can be stressful, with stimuli coming from all corners. Just want to let it go? Check out Samana Float Center, where you can spend ninety minutes floating in a sensory-deprivation tank. You won't hear anything, you won't see anything, and with water high in saline concentration and at body temperature, this is as close as you'll come to floating in outer space. Try a single session for $65; if you like it, you can upgrade to a monthly membership. The center touts the therapeutic nature of floating, suggesting that it can help with anxiety, depression and even insomnia. We guarantee that it will help you relax...and come clean.
