When I was asked to give an impromptu short talk and then calculate in reverse in intervals of 17 – before a trio of unknown individuals – the intense pressure was written on my face.

The reason was that psychologists were filming this somewhat terrifying experience for a research project that is examining tension using infrared imaging.

Stress alters the blood flow in the face, and researchers have found that the drop in temperature of a subject's face can be used as a gauge of anxiety and to monitor recovery.

Infrared technology, as stated by the scientists conducting the research could be a "game changer" in anxiety studies.

The Research Anxiety Evaluation

The research anxiety evaluation that I participated in is meticulously designed and purposely arranged to be an unpleasant surprise. I came to the university with minimal awareness what I was about to experience.

Initially, I was told to settle, relax and hear ambient sound through a pair of earphones.

So far, so calming.

Afterward, the investigator who was conducting the experiment introduced a group of unfamiliar people into the area. They all stared at me silently as the researcher informed that I now had a brief period to develop a brief presentation about my "ideal career".

When noticing the temperature increase around my collar area, the experts documented my face changing colour through their heat-sensing equipment. My nose quickly dropped in warmth – appearing cooler on the heat map – as I considered how to bluster my way through this spontaneous talk.

Research Findings

The scientists have conducted this same stress test on numerous subjects. In each, they noticed the facial region decrease in warmth by between three and six degrees.

My facial temperature decreased in warmth by a small amount, as my physiological mechanism shifted blood distribution from my nasal region and to my sensory systems – a bodily response to enable me to see and detect for hazards.

Most participants, like me, bounced back rapidly; their noses warmed to normal readings within a brief period.

Principal investigator explained that being a media professional has probably made me "somewhat accustomed to being put in anxiety-provoking circumstances".

"You're familiar with the recording equipment and speaking to unknown individuals, so you're likely somewhat resistant to social stressors," she explained.

"But even someone like you, trained to be stressful situations, exhibits a bodily response alteration, so that suggests this 'nose temperature drop' is a consistent measure of a shifting anxiety level."

Stress Management Applications

Stress is part of life. But this revelation, the researchers state, could be used to aid in regulating negative degrees of stress.

"The duration it takes a person to return to normal from this cooling effect could be an reliable gauge of how effectively somebody regulates their anxiety," said the head scientist.

"Should they recover unusually slowly, could that be a potential indicator of mental health concerns? Could this be a factor that we can address?"

As this approach is non-invasive and records biological reactions, it could also be useful to track anxiety in newborns or in people who can't communicate.

The Mental Arithmetic Challenge

The subsequent challenge in my tension measurement was, in my view, more difficult than the first. I was instructed to subtract backwards from 2023 in steps of 17. One of the observers of three impassive strangers interrupted me each instance I calculated incorrectly and asked me to start again.

I admit, I am bad at mental arithmetic.

During the embarrassing length of time attempting to compel my mind to execute arithmetic operations, all I could think was that I wanted to flee the progressively tense environment.

In the course of the investigation, just a single of the multiple participants for the anxiety assessment did actually ask to leave. The remainder, comparable to my experience, finished their assignments – presumably feeling assorted amounts of discomfort – and were compensated by a further peaceful interval of white noise through earphones at the conclusion.

Non-Human Applications

Perhaps one of the most remarkable features of the approach is that, because thermal cameras record biological tension reactions that is innate in numerous ape species, it can additionally be applied in non-human apes.

The scientists are actively working on its implementation within habitats for large monkeys, comprising various ape species. They seek to establish how to decrease anxiety and improve the wellbeing of animals that may have been saved from harmful environments.

Scientists have earlier determined that showing adult chimpanzees recorded material of infant chimps has a soothing influence. When the scientists installed a visual device close to the protected apes' living area, they observed the nasal areas of animals that watched the material warm up.

So, in terms of stress, observing young creatures interacting is the contrary to a surprise job interview or an spontaneous calculation test.

Potential Uses

Employing infrared imaging in primate refuges could demonstrate itself as valuable in helping rescued animals to adjust and settle in to a different community and unknown territory.
