The "Long Life" breathing training instrument, developed in Japan, is designed to enhance breathing and oral muscle function, particularly for the elderly. Widely used in Japanese nursing homes and elderly centers, it has been shown to increase exhalation time by over 30% with consistent practice, positively impacting voice and swallowing abilities. The product range includes five levels (0, 1, 2, 3, MAX) based on exhalation pressure. Usage Instructions: Take a deep breath and blow for 5–10 seconds. Perform 3 sets daily (morning, noon, evening), with each set consisting of 10–30 repetitions.
