It is likely that you will feel results after your first float. Your skin will feel soft and your body will feel relaxed.
But, let me expand on your question. First of all, the “results” of floating vary from person to person, and from float to float. For instance, sometimes, the primary result of your float may be physical relaxation. Other times, your mental clarity and calm might stand out.
During your first few floats, you are still becoming acquainted with the tank, so you may spend time thinking about the walls around you. But this will decrease over time. The more you float, the faster you will slip into a relaxation state.
For most people, we notice that the floating environment becomes familiar to people after about three sessions. For this reason, we offer a three float package that you can find here.
