Each breathing is unique. A team of scientists has shown that it is possible to identify people – with an accuracy of 96.8% – based only on their way of breathing. In addition, the mechanism leaves some ‘marks’ that They can reveal health information physical and mental of the person.
In mammals, the brain processes olfactory information during inhalation. This connection between the brain and breathing led researchers to ask: since each brain is unique, Wouldn’t that be reflected in each person’s breathing pattern?
To test this idea, they designed a light and portable device that records the nasal air flow continuously for 24 hours by flexible tubes placed under the nostrils.
Most breathing tests last between one and twenty minutes, and focus on evaluating pulmonary function or diagnosing diseases but those short snapshots are not enough to capture subtle patterns.

You might think that breathing has been measured and analyzed in all possible ways, ”says author Noam Sobel, of the Weizmann Institute of Sciences, in Israel,“ however, we encounter a completely new way to see our breath. We believe it is a reading of the brain. ”
The authors of the study, who have published the results of the study in Current Biology magazine, equipped a hundred healthy young adults with the device and asked them to continue with their daily lives.
With the data collected, they identified the people using only their Respiratory patterns With great precision.
This high level of precision remained constant in multiple repeated tests carried out for a period of two years, rivaling the precision of some voice recognition technologies.
“I thought it would be very difficult to identify someone because everyone does different things, such as running, studying or resting, but it turns out that their breathing patterns were remarkably different,” explains author Timna Soroka, of the Weizmann Institute of Sciences.

Respiratory marks
The study also discovered that respiratory marks were correlated with the body mass index of a person, their sleep-vigilia cycle, their levels of depression and anxiety, and even their behavior features.
For example, participants who obtained relatively higher scores in anxiety questionnaires had shorter inhalations and more variability in pauses between breaths during sleep.
Soroka said that none of the participants fulfilled the clinical diagnostic criteria for mental or behavioral disorders.
For authors, these results suggest that long -term monitoring of nasal air flow can serve as an indicator of physical and emotional well -being.
