Unveiling breath as a unique identifier: A revolutionary discovery
Turns out, your breathing pattern is almost as unique as your fingerprint. A new study found that tracking how you breathe can identify you with nearly 97% accuracy—right up there with some voice recognition tech. Researchers conducted retests over a two-year period with 100 young adults, using a wearable device that recorded their nasal airflow for a full day.
How researchers tracked participants' breathing
Participants wore soft tubes under their noses to track airflow while they went about their usual routines. Unlike quick breathing tests, this setup let researchers spot each person's unique "breathprint," even after retesting months later.
Breathing patterns linked to mental health, sleep habits
The study also noticed links between breathing patterns and things like BMI, sleep habits, and mental health. This could mean easier ways to check on health—or even new tools for diagnostics—just by paying attention to how we breathe.
