Upon being told to present an off-the-cuff short talk and then calculate in reverse in steps of 17 – before a trio of unknown individuals – the acute stress was visible in my features.

This occurred since researchers were documenting this somewhat terrifying situation for a research project that is examining tension using heat-sensing technology.

Stress alters the circulation in the face, and scientists have discovered that the cooling effect of a person's nose can be used as a indicator of tension and to observe restoration.

Thermal imaging, based on researcher findings behind the study could be a "revolutionary development" in stress research.

The Scientific Tension Assessment

The experimental stress test that I participated in is carefully controlled and purposely arranged to be an unexpected challenge. I came to the research facility with no idea what I was about to experience.

To begin, I was told to settle, relax and experience background static through a pair of earphones.

So far, so calming.

Then, the investigator who was conducting the experiment introduced a trio of unknown individuals into the area. They collectively gazed at me quietly as the investigator stated that I now had three minutes to create a short talk about my "ideal career".

When noticing the warmth build around my collar area, the experts documented my skin tone shifting through their thermal camera. My nose quickly dropped in heat – turning blue on the infrared display – as I thought about how to navigate this impromptu speech.

Research Findings

The scientists have performed this identical tension assessment on numerous subjects. In all instances, they noticed the facial region decrease in warmth by a noticeable amount.

My facial temperature decreased in temperature by a small amount, as my nervous system redirected circulation from my nasal region and to my sensory systems – a physiological adaptation to assist me in observe and hear for hazards.

The majority of subjects, comparable to my experience, recovered quickly; their facial temperatures rose to baseline measurements within a few minutes.

Principal investigator explained that being a media professional has probably made me "somewhat accustomed to being subjected to stressful positions".

"You're accustomed to the recording equipment and conversing with unknown individuals, so you're probably relatively robust to interpersonal pressures," she explained.

"However, even individuals such as yourself, accustomed to being anxiety-provoking scenarios, demonstrates a biological blood flow shift, so this indicates this 'nose temperature drop' is a consistent measure of a changing stress state."

Anxiety Control Uses

Anxiety is natural. But this discovery, the experts claim, could be used to help manage negative degrees of stress.

"The duration it takes someone to recover from this temperature drop could be an objective measure of how effectively an individual controls their anxiety," said the principal investigator.

"If they bounce back unusually slowly, could that be a warning sign of mental health concerns? Is this an aspect that we can tackle?"

Because this technique is non-intrusive and monitors physiological changes, it could furthermore be beneficial to monitor stress in infants or in individuals unable to express themselves.

The Mental Arithmetic Challenge

The second task in my anxiety evaluation was, in my view, more difficult than the initial one. I was instructed to subtract in reverse starting from 2023 in increments of seventeen. Someone on the panel of three impassive strangers stopped me each instance I made a mistake and instructed me to start again.

I acknowledge, I am inexperienced in doing math in my head.

As I spent uncomfortable period trying to force my brain to perform mathematical calculations, the only thought was that I desired to escape the progressively tense environment.

During the research, just a single of the 29 volunteers for the anxiety assessment did actually ask to depart. The rest, similar to myself, finished their assignments – likely experiencing different levels of humiliation – and were rewarded with another calming session of background static through earphones at the end.

Non-Human Applications

Possibly included in the most remarkable features of the method is that, since infrared imaging measure a physical stress response that is inherent within various monkey types, it can also be used in animal primates.

The researchers are actively working on its application in sanctuaries for great apes, including chimpanzees and gorillas. They aim to determine how to reduce stress and enhance the welfare of animals that may have been removed from harmful environments.

Scientists have earlier determined that presenting mature chimps recorded material of infant chimps has a calming effect. When the scientists installed a display monitor adjacent to the rehabilitated primates' habitat, they saw the noses of creatures that observed the material increase in temperature.

So, in terms of stress, viewing infant primates interacting is the opposite of a surprise job interview or an impromptu mathematical challenge.

Potential Uses

Employing infrared imaging in primate refuges could turn out to be valuable in helping rescued animals to adapt and acclimate to a different community and unknown territory.
