Breathing is as natural and unconscious as the pounding of a heartbeat. The majority of us don't consciously process each inhalation or exhalation. However, an intriguing recent study finds that the way you breathe may be as distinctly identifiable as your fingerprint. Scientists have found that each human has a personalized "respiratory fingerprint"—a breathing cycle so unique it can recognize an individual with almost 97% accuracy.

This new discovery has implications far beyond interest. From assessing mental illness to safeguarding biometric privacy, your breath could tell us more about you than you ever knew.

Carried out by researchers at the Weizmann Institute of Science in Israel, the research was headed by doctoral candidate Timna Soroka and published on June 12 in Current Biology. Researchers recruited 97 volunteers, who wore a device called the "Nasal Holter" for 24 straight hours. The wearable device, which weighed only 22 grams, took measurements of their natural breathing rhythms—while sleeping, working, resting, and going about their daily activities.

The payoff: By examining the subtle temporal rhythms of nasal breathing, scientists were able to determine that each subject's breath could identify him with 96.8% accuracy. The sensor tracked everything from inhale-exhale patterns to pauses before and after breathing, revealing a distinct rhythmic signature for every person.

What Is a "Respiratory Fingerprint"?

The "respiratory fingerprint" is the complex breathing pattern—how much, how frequently, and with what rhythm a person breathes. It may sound too ordinary to be special, but breathing is controlled by the brain's intricate respiratory control network. And because every brain is different, so is the breath it controls.

Lead researcher Noam Sobel said the team broke each 24-hour dataset into five-minute chunks and considered dozens of features with machine learning. They included esoteric but revealing traits like the time between inhalation and exhalation and the normal flip in airflow between nostrils.

Surprisingly, the research didn't rest there. Researchers cross-referenced the breathing information for each participant with a question about mental and physical health. What they discovered was nothing short of intriguing: higher self-reported anxiety individuals had more variability in their pauses between breaths. Other aspects of breathing pattern also matched up with BMI and other bodily states.

This linking of breathing and mind supports the increasingly robust literature suggesting that breath is a compelling diagnostic device—one that indicates not only lung function but also psychological and neurological well-being.

Renato Zenobi, an analytical chemistry professor at ETH Zurich, who was not part of the research, described the findings as "novel." According to him, the research would improve the significance of breath analysis as a non-invasive diagnostic tool. When applied along with breath metabolite testing, it would reinforce the accuracy of diagnosing metabolic disorders to anxiety and depression.

Envision a future in which a wristwatch-size device silently tracks your breath and warns your doctor of incipient signs of Parkinson's disease, sleep apnea, or even a panic attack. This would provide unprecedented preventive treatment with no needles, no scans, and no self-reporting bias.

What About Privacy?

As exciting as these breakthroughs are, they introduce a raft of ethical considerations. If our breath is a biometric signature, can it be used for monitoring? Currently, the Nasal Holter needs to be in direct contact and requires hours of usage. But with developing sensor technology, it's possible that distant breath monitoring could be achieved.

Soroka and Sobel recognize these issues and call for balancing scientific advancement with protecting privacy. Biological information such as breathing rates is involuntarily generated—i.e., we exhibit it all the time, whether we mean to or not. If it becomes readable from a distance, it might redefine the terms of biological privacy.

Real-World Limitations and Challenges

Notwithstanding the enthusiasm, the research is not without limitations. The population used was primarily healthy, young adults, and one can raise issues regarding the universality of the findings for children, the elderly, or people with respiratory illness. Also, wearing the device for 24 hours was daunting for some participants—especially while sleeping, when the nasal tubes fell out of position from time to time.

And although there was a high degree of association between breathing patterns and subjects' self-rated state of anxiety, these tests were not clinically certified. Additional research is required to determine if respiratory prints can accurately identify diagnosed medical or psychological illnesses.

We are headed toward an age when breath diagnostics could become a part of routine healthcare but as is the case with all great technologies, this development will need to be taken cautiously, respecting peoples' privacy and having ethical standards clear. As your lungs rhythmically fill and empty with air, they could be speaking your story in ways unimaginable to you.

Two passengers travelling in Singapore airlines arrived in New Zealand with measles symptoms. However, reported The Strait Times, that they are not linked to any other known cases, as noted by the Communicable Disease Agency (CDA).

The agency told the media outlet that it was notified on February 25 that two Singapore Airlines (SIA) passengers infected with measles landed in Auckland, New Zealand. Both were from the same household and flown from Hyderabad, India. They transited in Singapore for two hours before boarding an SIA flight to Auckland.

CDA investigation also revealed that these two cases remained in the transit area at Changi Airport. Associate Professor Lim Poh Lian, group director of the CDA's Communicable Disease Programmes, as reported by The Strait Times noted that the individuals were reported to have developed symptoms only while onboard the flight from Singapore to Auckland.

New Zealand media earlier reported that the two cases were detected after the individuals arrived in Auckland on flight SQ281 on February 17. The country’s public health authority began tracing passengers seated in rows 31 to 46 on the same flight, along with people who were present in the waiting area of Waitakere Hospital’s Emergency Department on February 21.

“Based on the onset of their symptoms, they were infected before transiting through Singapore and are not linked to any other known measles cases in Singapore,” Prof Lim said.

She also clarified that their time in transit through Singapore did not coincide with that of a previously reported measles case involving a passenger who had passed through Singapore en route to Los Angeles in the United States.

What Is Measles?

Measles has a high transmissibility, and high measles immunity levels are required to prevent sustained measles virus transmission.

This is why herd immunity for measles could be easily breached.

It easily spreads from one infected person to another through breathes, coughs or sneezes and could cause severe disease, complications, and even death.

Symptoms include:

• High fever
• Cough
• Runny Nose
• Rash all over the body

The most unique symptom or the early sign of measles in the Koplik spots. These are tiny white dots that look like grains of salt on red gums inside the cheeks that appear before the red rash starts to appear on a person's face and then the body.

Furthermore, the symptoms of measles are also characterized by the three Cs:

• Cough
• Coryza or runny nose
• Conjunctivitis or red and water eyes

Update On The Passengers Who Landed In New Zealand

The passenger on flight SQ38 arrived at Los Angeles International Airport at about 7pm on February 9, after a roughly two-and-a-half-hour transit at Changi Airport following a flight from Cambodia.

Prof Lim said the most effective protection against measles is to be fully vaccinated before travelling. She also advised travellers to practise good hygiene, such as washing hands regularly and avoiding close contact with anyone who is unwell.

Anyone who develops symptoms like fever, rash, cough, red or watery eyes, or a runny nose should wear a mask, seek medical care promptly, and inform their doctor about their recent travel and any possible exposure to measles, she added.

In response to queries, Singapore Airlines told The Straits Times that it is working closely with the authorities but cannot share specific details due to customer confidentiality.

In a major push towards eliminating cervical cancer from India, Prime Minister Narendra Modi today launched the nationwide Human Papillomavirus (HPV) vaccination program for girls aged 14 years.

The new vaccination drive comes as cervical cancer remains the second most common cancer among women in India, with nearly 80,000 new cases and over 42,000 deaths reported annually. As per data from the ICMR-National Cancer Registry Program (NCRP), an estimated 78,499 new cases and 42,392 deaths were reported in 2024.

Calling it a "decisive step”, the government noted that it is aimed at “strengthening the vision of ‘swasth nari’ (healthy women) while being rooted in scientific evidence, strict regulatory oversight and global best practices”.

“India's vaccination drive reflects safety, responsibility, and long-term commitment to women’s health,” it added.

The national program will use Gardasil, a quadrivalent HPV vaccine that protects against HPV types 16 and 18, which cause cervical cancer, as well as types 6 and 11.

However, social media has been rife with concerns around the safety of the vaccine, its impact on women’s reproductive health, among others.

HPV Vaccine: The Myths And Facts

Myth: HPV vaccines can cause severe side effects and even death.

Fact: The HPV vaccines come with a “confirmed strong safety record”.

“Extensive global monitoring shows a strong safety profile supported by scientific reviews. Independent evaluations have found no causal link between vaccination and chronic harm, strengthening confidence in its continued use worldwide,” the government said.

The vaccine has been licensed in India since 2008, and the new rollout follows recommendations by the World Health Organization (WHO) and approvals from the National Technical Advisory Group on Immunization (NTAGI).

“HPV vaccines have been given to hundreds of millions globally. Extensive post-marketing surveillance shows an excellent safety profile, with no causal link to serious adverse outcomes. The evidence is robust, transparent, and reassuring,” Dr. CS Pramesh, Director of the Tata Memorial Hospital, Mumbai, shared in a post on the social media platform X.

Myth: The HPV vaccine has never been used in India

Fact: The vaccine has been in use in India. It has been administered for years since 2008 with successful implementation in states like Punjab, Sikkim, and Tamil Nadu.

Myth: HPV vaccination does not prevent cervical cancer

Fact: The HPV vaccine has been proven to prevent cervical cancer

Studies show a 65 percent drop in cervical cancer cases among US women between 2012 and 2019 and an 88-89 percent reduction in precancerous lesions among Scottish women over a decade.

Countries with early HPV vaccine adoption have also shown large declines in HPV infection, high-grade cervical lesions, and cervical cancer incidence.

"Even when considering the rarest side effects, HPV vaccines are overwhelmingly safe. The protection they offer against cervical cancer far outweighs the minimal risks. Parents are encouraged to vaccinate their daughters on time," said Dr. Neena Malhotra, Professor and Head of Department, Department of Obstetrics and Gynecology, AIIMS New Delhi on X.

Myths: Are Multiple Doses Needed?

Fact: A single dose of the quadrivalent HPV vaccine is effective. It provides strong protection against HPV infection. It helps prevent cervical cancer.

“Strong global and Indian scientific evidence confirms that a single dose provides robust and durable protection when administered to girls in the recommended age group," the government said.

Prime Minister Narendra Modi today launched the nationwide Human Papillomavirus (HPV) vaccination campaign for girls aged 14 years from Rajasthan's Ajmer.

The initiative marks a decisive step towards eliminating cervical cancer through timely HPV vaccination. Cervical cancer remains the second most common cancer among women in India. Nearly 80,000 new cases and over 42,000 deaths are reported annually in the country.

"Today, I have had the opportunity to launch the HPV vaccine campaign from Ajmer. This campaign is an important step towards empowering women and daughters of this country,” PM Modi said.

“For us, this was a sensitive issue tied to the insult of our sisters and daughters, one that made them ill. That is why we resolved it at a crucial turning point in their mission,” he added.

The World Health Organization has also lauded India's mission to launch the HPV vaccine and prevent the risk of cervical cancer.

“We are leaving no stone unturned to ensure that the daughters of the country are healthy and prosperous. The objective of this initiative is the prevention of cervical cancer," the Prime Minister, earlier wrote in a post on social media platform X.

The HPV Vaccination Campaign

The nationwide program, based on expert recommendations of the National Technical Advisory Group on Immunization (NTAGI), will target girls aged 14 years.

At 14, the HPV vaccine offers maximum preventive benefit, well before potential exposure to the virus.

"By prioritizing prevention at the right age, the program is expected to provide lifelong protection and significantly reduce the future burden of cervical cancer in the country," the government said.

“The HPV vaccine works best at 9-14 years, before exposure, and when the immune response is strongest. Studies show effectiveness is highest in younger age groups and decreases with age,” Dr. Parmod Kumar, Associate Professor in Medical Oncology, AIIMS Jodhpur, shared on X.

Vaccination under the national program will be voluntary and free of cost.

The HPV vaccination will be conducted exclusively at designated government health facilities, including Ayushman Arogya Mandirs (Primary Health Centers), Community Health Centers, Sub-District and District Hospitals, and Government Medical Colleges.

Cervical Cancer Burden In South East Asia

Despite being preventable, cervical cancer continues to claim the life of a woman every two minutes globally, and the WHO South-East Asia Region bears nearly one-quarter of the global burden.

Dr. Catharina Boehme, Officer-in-Charge, WHO South-East Asia, stated that the introduction of HPV vaccination at a national scale in India "will have a far-reaching impact". It will accelerate progress not only for the country, but for the region and the world, she said.

“This landmark step, led at the highest level of government, reflects India’s strong commitment to protecting adolescent girls from cervical cancer," said Dr. Boehme.

With today’s milestone, nine of the 10 countries in the Region now include HPV vaccination in their national immunization programs.

The WHO global targets for 2030 include vaccinating 90 percent of girls by age 15, screening 70 percent of women by ages 35 and 45, and ensuring 90 percent of women with pre-cancer and invasive cancer receive appropriate treatment.
