When I was asked to deliver an unprepared brief presentation and then calculate in reverse in steps of 17 – all in front of a panel of three strangers – the acute stress was visible in my features.
The reason was that psychologists were filming this quite daunting situation for a investigation that is analyzing anxiety using thermal cameras.
Anxiety modifies the circulation in the facial area, and scientists have discovered that the cooling effect of a subject's face can be used as a gauge of anxiety and to track recuperation.
Thermal imaging, as stated by the scientists behind the study could be a "revolutionary development" in anxiety studies.
The scientific tension assessment that I subjected myself to is meticulously designed and intentionally created to be an discomforting experience. I arrived at the research facility with minimal awareness what I was in for.
First, I was told to settle, calm down and listen to background static through a audio headset.
So far, so calming.
Afterward, the scientist who was conducting the experiment introduced a group of unfamiliar people into the area. They each looked at me without speaking as the researcher informed that I now had 180 seconds to prepare a five minute speech about my "dream job".
While experiencing the temperature increase around my neck, the researchers recorded my complexion altering through their thermal camera. My nose quickly dropped in warmth – appearing cooler on the infrared display – as I thought about how to manage this unplanned presentation.
The investigators have performed this equivalent anxiety evaluation on 29 volunteers. In all instances, they observed the nasal area cool down by several degrees.
My nasal area cooled in temperature by two degrees, as my physiological mechanism pushed blood flow away from my face and to my visual and auditory organs – a physical reaction to enable me to see and detect for danger.
Most participants, similar to myself, recovered quickly; their facial temperatures rose to normal readings within a few minutes.
Head scientist noted that being a journalist and presenter has probably made me "quite habituated to being put in tense situations".
"You're familiar with the camera and talking with unknown individuals, so you're likely somewhat resistant to social stressors," the researcher noted.
"But even someone like you, experienced in handling anxiety-provoking scenarios, shows a physiological circulation change, so which implies this 'nasal dip' is a robust marker of a changing stress state."
Stress is part of life. But this finding, the experts claim, could be used to aid in regulating damaging amounts of stress.
"The length of time it takes a person to return to normal from this cooling effect could be an objective measure of how efficiently somebody regulates their anxiety," noted the principal investigator.
"If they bounce back remarkably delayed, could this indicate a warning sign of mental health concerns? Is this an aspect that we can do anything about?"
Since this method is non-intrusive and records biological reactions, it could also be useful to observe tension in infants or in those with communication challenges.
The subsequent challenge in my tension measurement was, from my perspective, more challenging than the initial one. I was told to calculate sequentially decreasing from 2023 in intervals of 17. Someone on the panel of three impassive strangers interrupted me every time I committed an error and instructed me to recommence.
I confess, I am bad at mental arithmetic.
During the awkward duration attempting to compel my mind to execute arithmetic operations, the only thought was that I wanted to flee the growing uncomfortable space.
Throughout the study, just a single of the 29 volunteers for the anxiety assessment did truly seek to leave. The rest, similar to myself, completed their tasks – probably enduring different levels of discomfort – and were rewarded with another calming session of white noise through headphones at the finish.
Perhaps one of the most surprising aspects of the method is that, since infrared imaging measure a physical stress response that is natural to various monkey types, it can also be used in other species.
The scientists are presently creating its implementation within sanctuaries for great apes, including chimpanzees and gorillas. They aim to determine how to reduce stress and enhance the welfare of primates that may have been saved from traumatic circumstances.
Researchers have previously discovered that displaying to grown apes recorded material of young primates has a relaxing impact. When the scientists installed a video screen adjacent to the protected apes' living area, they observed the nasal areas of creatures that observed the footage increase in temperature.
Therefore, regarding anxiety, observing young creatures playing is the contrary to a surprise job interview or an on-the-spot subtraction task.
Implementing heat-sensing technology in ape sanctuaries could turn out to be beneficial in supporting rehabilitated creatures to become comfortable to a unfamiliar collective and unknown territory.
