Breathing is one of the most fundamental processes of human life, yet it is often overlooked in everyday wellness routines. Many people focus on exercise, nutrition, and sleep but may not actively train or optimize their respiratory health. Devices designed for respiratory muscle training and breathing support have gained attention as individuals seek ways to improve lung performance, relaxation, endurance, and breathing awareness. One such device is AirZa, a portable respiratory trainer designed to support breathing optimization through guided exhala-tion and visual feedback.
