Scientists discover breathing patterns can identify individuals with near fingerprint-like accuracy.

Scientists have found that each person's breathing pattern is as unique as a fingerprint, allowing individuals to be identified with 96.8% accuracy. A lightweight wearable device tracks nasal airflow for 24 hours, revealing patterns linked to BMI, sleep cycles, and mental health like depression and anxiety. Researchers aim to make the device more comfortable for everyday use and explore if mimicking healthy breathing can improve mental states.
