Unlocking the Unique Respiratory Fingerprint of Every Individual
Every single human on this planet is as distinct as a snowflake; a combination of traits and genes and microbes that, as far as we can tell, is not replicated exactly in any other single human.
One of the traits that is unique to each individual is the breath that sustains us. Each person has an idiosyncratic pattern to the constant inhale-exhale that counts out our hours, days, and years on this planet.
A recent study by a team of scientists delved into this uniqueness by fitting people with a wearable device that monitored their nasal breathing. The data collected revealed patterns that were detailed enough for the researchers to identify individuals with an impressive accuracy of 96.8 percent.
This ‘respiratory fingerprint’, as termed by the team led by brain scientist Timna Soroka of the Weizmann Institute of Science in Israel, could pave the way for new ways to understand and treat physical and mental ailments.

“You would think that breathing has been measured and analyzed in every way,” says neuroscientist Noam Sobel of the Weizmann Institute of Science. “Yet we stumbled upon a completely new way to look at respiration. We consider this as a brain readout.”
Respiration is a process that we often take for granted, but it is governed by a complex and extensive brain network that can be consciously controlled by individuals when necessary. The team at the Weizmann Olfaction Research Group, led by Soroka and Sobel, have been exploring the brain’s processing of scent during inhalation, which led them to investigate the concept of a breath-print.
The development of a wearable device capable of monitoring nasal breathing over extended periods allowed the researchers to gather data from 100 participants over 24 hours, providing a detailed insight into each individual’s breathing patterns.

Through the analysis of the collected data using the BreathMetrics protocol, which examines 24 parameters of nasal respiration, the researchers not only could identify individuals based on their breathing patterns but also infer certain traits and behaviors. From rest to exertion, each person’s breathing pattern tells a unique story.
The study participants’ breathing patterns were found to correlate with their BMI and even mental health status. Individuals with reported anxiety showed distinct breathing patterns, indicating a potential link between respiratory behavior and psychological well-being.
Looking ahead, the researchers are eager to explore how this newfound understanding of respiratory fingerprints can be applied in diagnostics and potentially even in the treatment of various diseases by modifying breathing patterns.
The study, shedding light on the intricate world of individualized respiration, has been published in Current Biology.
