Upon being told to present an off-the-cuff brief presentation and then calculate in reverse in intervals of 17 – before a trio of unknown individuals – the intense pressure was visible in my features.

That is because researchers were documenting this somewhat terrifying experience for a investigation that is analyzing anxiety using infrared imaging.

Anxiety modifies the blood flow in the facial area, and experts have determined that the thermal decrease of a person's nose can be used as a measure of stress levels and to observe restoration.

Heat mapping, as stated by the scientists behind the study could be a "revolutionary development" in tension analysis.

The Research Anxiety Evaluation

The research anxiety evaluation that I participated in is meticulously designed and deliberately designed to be an unexpected challenge. I visited the university with minimal awareness what I was in for.

First, I was instructed to position myself, calm down and listen to white noise through a pair of earphones.

So far, so calming.

Then, the researcher who was conducting the experiment invited a trio of unknown individuals into the space. They all stared at me silently as the scientist explained that I now had a brief period to prepare a brief presentation about my "ideal career".

While experiencing the heat rise around my neck, the experts documented my skin tone shifting through their thermal camera. My nasal area rapidly cooled in temperature – appearing cooler on the heat map – as I contemplated ways to navigate this spontaneous talk.

Scientific Results

The scientists have performed this same stress test on numerous subjects. In each, they saw their nose decrease in warmth by several degrees.

My nasal area cooled in heat by a couple of degrees, as my biological response system pushed blood flow away from my nose and to my eyes and ears – a physiological adaptation to help me to see and detect for threats.

Nearly all volunteers, like me, recovered quickly; their noses warmed to pre-stressed levels within a short time.

Principal investigator stated that being a reporter and broadcaster has probably made me "quite habituated to being put in stressful positions".

"You're familiar with the filming device and talking with unknown individuals, so you're probably quite resilient to social stressors," the scientist clarified.

"But even someone like you, accustomed to being stressful situations, demonstrates a physiological circulation change, so which implies this 'facial cooling' is a reliable indicator of a shifting anxiety level."

Anxiety Control Uses

Stress is part of life. But this finding, the researchers state, could be used to aid in regulating damaging amounts of tension.

"The period it takes a person to return to normal from this temperature drop could be an objective measure of how efficiently a person manages their stress," explained the principal investigator.

"When they return exceptionally gradually, might this suggest a risk marker of psychological issues? Is this an aspect that we can address?"

As this approach is non-intrusive and records biological reactions, it could furthermore be beneficial to monitor stress in infants or in those with communication challenges.

The Mental Arithmetic Challenge

The second task in my stress assessment was, personally, more difficult than the opening task. I was told to calculate backwards from 2023 in steps of 17. Someone on the panel of three impassive strangers stopped me every time I calculated incorrectly and told me to recommence.

I acknowledge, I am poor with calculating mentally.

During the uncomfortable period attempting to compel my mind to execute subtraction, the only thought was that I desired to escape the growing uncomfortable space.

During the research, just a single of the numerous subjects for the anxiety assessment did truly seek to exit. The others, like me, accomplished their challenges – probably enduring different levels of humiliation – and were rewarded with an additional relaxation period of white noise through audio devices at the end.

Non-Human Applications

Possibly included in the most surprising aspects of the technique is that, since infrared imaging record biological tension reactions that is inherent within numerous ape species, it can additionally be applied in non-human apes.

The scientists are actively working on its use in sanctuaries for great apes, including chimpanzees and gorillas. They want to work out how to reduce stress and improve the wellbeing of animals that may have been removed from traumatic circumstances.

Researchers have previously discovered that displaying to grown apes recorded material of infant chimps has a relaxing impact. When the scientists installed a video screen close to the rehabilitated primates' habitat, they observed the nasal areas of animals that watched the content heat up.

Consequently, concerning tension, viewing infant primates engaging in activities is the inverse of a unexpected employment assessment or an on-the-spot subtraction task.

Future Applications

Employing infrared imaging in monkey habitats could prove to be beneficial in supporting protected primates to adapt and acclimate to a unfamiliar collective and unfamiliar environment.
