After being requested to give an impromptu brief presentation and then calculate in reverse in intervals of 17 – while facing a panel of three strangers – the intense pressure was written on my face.

The reason was that psychologists were documenting this quite daunting experience for a research project that is examining tension using infrared imaging.

Stress alters the blood flow in the face, and scientists have discovered that the drop in temperature of a subject's face can be used as a gauge of anxiety and to track recuperation.

Heat mapping, according to the psychologists conducting the research could be a "transformative advancement" in stress research.

The Research Anxiety Evaluation

The research anxiety evaluation that I subjected myself to is precisely structured and intentionally created to be an unexpected challenge. I visited the university with minimal awareness what I was about to experience.

First, I was told to settle, calm down and experience ambient sound through a set of headphones.

Up to this point, very peaceful.

Afterward, the scientist who was overseeing the assessment invited a panel of three strangers into the area. They all stared at me without speaking as the scientist explained that I now had 180 seconds to create a five minute speech about my "perfect occupation".

While experiencing the temperature increase around my neck, the scientists captured my complexion altering through their heat-sensing equipment. My nasal area rapidly cooled in warmth – appearing cooler on the thermal image – as I considered how to navigate this spontaneous talk.

Scientific Results

The investigators have carried out this identical tension assessment on multiple participants. In every case, they saw their nose cool down by a noticeable amount.

My facial temperature decreased in warmth by a small amount, as my nervous system pushed blood flow away from my nasal region and to my sensory systems – a physiological adaptation to assist me in look and listen for threats.

The majority of subjects, like me, recovered quickly; their nasal areas heated to baseline measurements within a short time.

Principal investigator explained that being a reporter and broadcaster has probably made me "relatively adapted to being subjected to anxiety-provoking circumstances".

"You're accustomed to the recording equipment and speaking to strangers, so you're likely relatively robust to social stressors," the researcher noted.

"However, even individuals such as yourself, accustomed to being anxiety-provoking scenarios, exhibits a bodily response alteration, so that suggests this 'nose temperature drop' is a reliable indicator of a shifting anxiety level."

Anxiety Control Uses

Tension is inevitable. But this discovery, the experts claim, could be used to aid in regulating damaging amounts of stress.

"The length of time it takes an individual to bounce back from this cooling effect could be an quantifiable indicator of how well a person manages their anxiety," explained the principal investigator.

"If they bounce back exceptionally gradually, could this indicate a risk marker of mental health concerns? Could this be a factor that we can address?"

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

The Mental Arithmetic Challenge

The second task in my anxiety evaluation was, personally, more difficult than the opening task. I was asked to count backwards from 2023 in steps of 17. Someone on the panel of unresponsive individuals interrupted me every time I made a mistake and told me to recommence.

I admit, I am poor with doing math in my head.

As I spent awkward duration trying to force my mind to execute subtraction, my sole consideration was that I wished to leave the growing uncomfortable space.

In the course of the investigation, only one of the 29 volunteers for the tension evaluation did actually ask to exit. The rest, like me, accomplished their challenges – probably enduring varying degrees of embarrassment – and were given another calming session of background static through earphones at the end.

Primate Study Extensions

Maybe among the most surprising aspects of the technique is that, because thermal cameras record biological tension reactions that is inherent within many primates, it can furthermore be utilized in animal primates.

The investigators are actively working on its use in refuges for primates, including chimpanzees and gorillas. They want to work out how to lower tension and improve the wellbeing of primates that may have been rescued from distressing situations.

Scientists have earlier determined that showing adult chimpanzees recorded material of young primates has a calming effect. When the scientists installed a display monitor adjacent to the protected apes' living area, they noticed the facial regions of creatures that observed the material increase in temperature.

Therefore, regarding anxiety, viewing infant primates playing is the opposite of a surprise job interview or an on-the-spot subtraction task.

Future Applications

Implementing heat-sensing technology in monkey habitats could prove to be beneficial in supporting protected primates to adjust and settle in to a different community and unknown territory.
