Described herein are a system and a method for automatically guiding and evaluating a user's performance during structured breathing exercise sessions. The system retrieves predetermined breathing patterns, including sequences of inhales, exhales, and breath-holds across one or more rounds. Each round includes at least two stages: a breath-hold stage and a first full breath stage immediately following the breath-hold. The system provides real-time guidance through sensory cues, receives user-initiated or automatic signals marking stage transitions, records the duration of each stage, and determines ideal or target durations. A longer first full breath duration indicates improved breath-hold performance and reduced stress. The system generates a final score for each round by combining breath-hold and first full breath durations, reflecting performance, relaxation, lung function, tolerance metrics, and the like. Aggregate session scores are computed across rounds, offering insights into exercise suitability, session effectiveness, and physiological adaptation over time.
