Upon being told to deliver an unprepared brief presentation and then calculate in reverse in steps of 17 – all in front of a trio of unknown individuals – the acute stress was visible in my features.

That is because psychologists were filming this rather frightening scenario for a research project that is examining tension using thermal cameras.

Anxiety modifies the blood flow in the countenance, and scientists have discovered that the cooling effect of a subject's face can be used as a gauge of anxiety and to monitor recovery.

Thermal imaging, according to the psychologists leading the investigation could be a "game changer" in anxiety studies.

The Experimental Stress Test

The experimental stress test that I subjected myself to is meticulously designed and deliberately designed to be an unexpected challenge. I arrived at the research facility with minimal awareness what I was about to experience.

To begin, I was told to settle, unwind and hear background static through a set of headphones.

Up to this point, very peaceful.

Then, the investigator who was running the test introduced a panel of three strangers into the area. They each looked at me quietly as the researcher informed that I now had a brief period to develop a five minute speech about my "dream job".

As I felt the warmth build around my neck, the researchers recorded my complexion altering through their heat-sensing equipment. My nose quickly dropped in temperature – turning blue on the thermal image – as I contemplated ways to navigate this spontaneous talk.

Research Findings

The investigators have performed this identical tension assessment on numerous subjects. In all instances, they noticed the facial region cool down by a noticeable amount.

My nasal area cooled in temperature by two degrees, as my nervous system shifted blood distribution from my nasal region and to my visual and auditory organs – a physical reaction to help me to look and listen for threats.

The majority of subjects, comparable to my experience, returned to normal swiftly; their nasal areas heated to normal readings within a few minutes.

Head scientist noted that being a reporter and broadcaster has probably made me "relatively adapted to being placed in stressful positions".

"You're familiar with the recording equipment and talking with unfamiliar people, so you're probably quite resilient to interpersonal pressures," the researcher noted.

"But even someone like you, trained to be stressful situations, demonstrates a biological blood flow shift, so that suggests this 'nasal dip' is a robust marker of a changing stress state."

Stress Management Applications

Tension is inevitable. But this discovery, the experts claim, could be used to aid in regulating harmful levels of tension.

"The period it takes someone to recover from this cooling effect could be an quantifiable indicator of how well a person manages their anxiety," said the principal investigator.

"If they bounce back exceptionally gradually, could that be a risk marker of psychological issues? Is this an aspect that we can do anything about?"

As this approach is non-invasive and records biological reactions, it could furthermore be beneficial to observe tension in newborns or in individuals unable to express themselves.

The Calculation Anxiety Assessment

The second task in my stress assessment was, from my perspective, even worse than the first. I was asked to count backwards from 2023 in intervals of 17. A member of the group of unresponsive individuals halted my progress whenever I calculated incorrectly and told me to begin anew.

I admit, I am poor with mental arithmetic.

During the embarrassing length of time attempting to compel my thinking to accomplish arithmetic operations, my sole consideration was that I desired to escape the progressively tense environment.

Throughout the study, only one of the multiple participants for the tension evaluation did truly seek to depart. The others, similar to myself, accomplished their challenges – presumably feeling assorted amounts of embarrassment – and were compensated by a further peaceful interval of white noise through earphones at the end.

Non-Human Applications

Perhaps one of the most unexpected elements of the method is that, because thermal cameras measure a physical stress response that is natural to many primates, it can furthermore be utilized in non-human apes.

The researchers are presently creating its application in habitats for large monkeys, including chimpanzees and gorillas. They want to work out how to decrease anxiety and improve the wellbeing of primates that may have been removed from distressing situations.

Researchers have previously discovered that showing adult chimpanzees video footage of young primates has a relaxing impact. When the investigators placed a visual device near the rehabilitated primates' habitat, they observed the nasal areas of creatures that observed the content warm up.

Consequently, concerning tension, viewing infant primates interacting is the inverse of a spontaneous career evaluation or an impromptu mathematical challenge.

Future Applications

Employing infrared imaging in monkey habitats could demonstrate itself as valuable in helping protected primates to adjust and settle in to a different community and strange surroundings.
