Stress means the distortion of the physical or mental condition, which is caused by various stressors. Various countermeasures are needed against stress because the distortion of the physical or mental condition causes various physical and mental illnesses. The purpose of this study is to create the concept design of a floating biofeedback system for mental management and health. Supine floating was adopted as the floating method for the system. For the purpose of this study, the effect of supine floating on the autonomic nervous system was investigated experimentally. Subjects underwent 2 types of relaxation. One was the supine floating in a swimming pool. Another was the supine on the matt. ECG data during the each supine was measured, transmitted to a computer, and transformed into a power spectrum by FFT. Furthermore, the breathing curved line in each supine was measured by the thermistor. The new concept design of a floating biofeedback system was created based on this experimental result.
