It is true that floating can bring about a certain degree of discomfort. This can happen for two reasons: 1. We can become conditioned to the amount of distraction and stimuli around us, and when this is removed it can in the beginning feel unfamiliar and uncomfortable 2. When we are freed from this distraction and stimuli we are creating space for other experiences to present themselves. If you do feel discomfort, we would recommend focusing on your breathing and remaining with the experience to your degree of tolerance. Of course, you remain in control, and can exit the tank and end your float at any point.
