Doctor listening to patient breathing

Although you do it tens of thousands of times a day, you probably rarely even notice when you breathe in and out. So it may come as a surprise to learn that the way you breathe is as unique as your fingerprints. Research has shown that individual breathing patterns — including the timing, volume, and rhythm of chest movements — can be used to identify people with up to 97% accuracy. Over the course of a day, the way you inhale and exhale creates a distinct respiratory signature as recognizable as your voice, walk, or facial features.

Your breath can reveal your health or mood.

It's a fact

Your breathing patterns can reflect your stress levels and emotional state and even signal illness. Researchers are continuing to explore how subtle shifts in breath, such as shallow breathing from anxiety, could become powerful diagnostic clues for physical and mental health.

As it turns out, the subtle ways humans breathe reflect a variety of influences. Your lung capacity, posture, muscle tone, emotional state, health conditions, and daily habits such as smoking or exercise all shape the unique way you breathe. Those small differences work together to create a remarkably consistent personal breathing pattern.

Although those patterns fluctuate with activity, mood, or stress, the unique recovery rhythms and variability in each person’s breath weave together into a biometric signature that may one day rival fingerprints or facial recognition as a secure method of identification.

Japan’s "ama" can spend up to two minutes underwater on a single breath.

Ama (“women of the sea”) are freedivers in Japan who have practiced breath-hold diving for centuries, employing their abnormal lung capacities to harvest shellfish and seaweed without any breathing gear. This practice likely began in coastal hunter-gatherer communities wherein women gathered seafood near the shore. While male divers also existed, women’s higher percentage of body fat made them better suited to withstand the cold waters.

Over time, the role became the exclusive domain of women, often passed down from mother to daughter, with some divers starting as early as age 12 and continuing into their 60s or 70s. Their incredible lung control and calm mindset enable them to dive deep in cold waters, preserving a 5,000-year tradition that continues today.
