Depending on how often you've floated and if you are an experienced floater or just a novice starting out you may notice that during your floatation therapy session, you are either in a full trance like state or have simply fallen asleep. If this occurs, you may start to feel stiff or tight around your ankles, wrist or hands.
Just a quick tip to help you out while you are floating on your back, is to try stretching your wrists and ankles by moving them in a circular motions. Start off in a clockwise direction, then change and go in a anti-clockwise direction. You can also point your toes upward (towards you), or downward (away from you). Repeat these actions as much as you need to while you are floating. These mobility movements can be done at the same time or separately. Bear in mind not only does this help free up your wrist and ankle joints, it can also act as a form of distraction to allow you to focus on something else until your ready to relax again.
