Can I drown and fall asleep in there?
There is around 10inches of water and 1000 pounds of Epsom Salt, it would be impossible to drown inside the float tank.
Some people fall asleep because of the deep relaxation floating provides, the water is incredibly buoyant that you stay afloat. Just one hour of floating is equivalent to 2-3 hours of deep sleep.
Many clients who suffer from insomnia or jet lag get immense relief from floating.
