When I was asked to present an off-the-cuff brief presentation and then subtract sequentially in increments of seventeen – while facing a panel of three strangers – the sudden tension was evident in my expression.

This occurred since psychologists were documenting this rather frightening situation for a research project that is examining tension using thermal cameras.

Tension changes the blood flow in the facial area, and researchers have found that the thermal decrease of a person's nose can be used as a indicator of tension and to monitor recovery.

Heat mapping, according to the psychologists behind the study could be a "transformative advancement" in anxiety studies.

The Experimental Stress Test

The experimental stress test that I participated in is meticulously designed and deliberately designed to be an unexpected challenge. I came to the research facility with little knowledge what I was about to experience.

To begin, I was instructed to position myself, calm down and listen to ambient sound through a pair of earphones.

Thus far, quite relaxing.

Subsequently, the investigator who was running the test invited a trio of unknown individuals into the room. They each looked at me without speaking as the investigator stated that I now had three minutes to prepare a brief presentation about my "perfect occupation".

As I felt the heat rise around my neck, the scientists captured my face changing colour through their heat-sensing equipment. My nasal area rapidly cooled in temperature – showing colder on the thermal image – as I contemplated ways to bluster my way through this unplanned presentation.

Research Findings

The investigators have conducted this equivalent anxiety evaluation on multiple participants. In all instances, they observed the nasal area cool down by several degrees.

My nose dropped in heat by two degrees, as my nervous system pushed blood flow away from my nasal region and to my sensory systems – a physical reaction to enable me to see and detect for hazards.

Nearly all volunteers, similar to myself, bounced back rapidly; their nasal areas heated to normal readings within a few minutes.

Head scientist noted that being a journalist and presenter has probably made me "relatively adapted to being placed in anxiety-provoking circumstances".

"You're familiar with the camera and speaking to unknown individuals, so you're likely somewhat resistant to public speaking anxieties," the scientist clarified.

"However, even individuals such as yourself, accustomed to being stressful situations, shows a physiological circulation change, so that suggests this 'nasal dip' 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 assist in controlling negative degrees of stress.

"The length of time it takes someone to recover from this temperature drop could be an objective measure of how well a person manages their anxiety," noted the head scientist.

"When they return unusually slowly, might this suggest a warning sign of psychological issues? Is it something that we can tackle?"

Because this technique is non-invasive and monitors physiological changes, it could also be useful to track anxiety in infants or in people who can't communicate.

The Mathematical Stress Test

The subsequent challenge in my stress assessment was, from my perspective, more challenging than the initial one. I was instructed to subtract sequentially decreasing from 2023 in increments of seventeen. One of the observers of expressionless people halted my progress each instance I committed an error and told me to begin anew.

I admit, I am bad at calculating mentally.

While I used uncomfortable period striving to push my brain to perform mathematical calculations, the only thought was that I wished to leave the progressively tense environment.

In the course of the investigation, just a single of the 29 volunteers for the anxiety assessment did actually ask to leave. The others, comparable to my experience, accomplished their challenges – probably enduring varying degrees of humiliation – and were compensated by a further peaceful interval of white noise through headphones at the end.

Non-Human Applications

Maybe among the most surprising aspects of the method is that, as heat-sensing technology measure a physical stress response that is inherent within numerous ape species, it can additionally be applied in other species.

The scientists are actively working on its implementation within refuges for primates, comprising various ape species. They seek to establish how to lower tension and boost the health of animals that may have been removed from distressing situations.

The team has already found that displaying to grown apes video footage of baby chimpanzees has a relaxing impact. When the researchers set up a visual device near the rehabilitated primates' habitat, they noticed the facial regions of primates that viewed the material warm up.

Therefore, regarding anxiety, watching baby animals engaging in activities is the contrary to a unexpected employment assessment or an spontaneous calculation test.

Potential Uses

Employing infrared imaging in ape sanctuaries could turn out to be valuable in helping rehabilitated creatures to adapt and acclimate to a unfamiliar collective and unknown territory.
