When I was asked to deliver an unprepared brief presentation and then subtract sequentially in increments of seventeen – all in front of a panel of three strangers – the intense pressure was visible in my features.

The reason was that researchers were filming this rather frightening scenario for a research project that is studying stress using thermal cameras.

Stress alters the blood flow in the facial area, and scientists have discovered that the cooling effect of a individual's nasal area can be used as a gauge of anxiety and to monitor recovery.

Heat mapping, based on researcher findings conducting the research could be a "revolutionary development" in anxiety studies.

The Experimental Stress Test

The scientific tension assessment that I underwent is meticulously designed and intentionally created to be an discomforting experience. I arrived at the research facility with little knowledge what I was in for.

Initially, I was asked to sit, calm down and experience ambient sound through a audio headset.

So far, so calming.

Subsequently, the researcher who was running the test invited a panel of three strangers into the room. They collectively gazed at me quietly as the scientist explained that I now had a brief period to develop a five minute speech about my "perfect occupation".

As I felt the temperature increase around my collar area, the researchers recorded my skin tone shifting through their heat-sensing equipment. My nose quickly dropped in temperature – turning blue on the heat map – as I thought about how to manage this unplanned presentation.

Scientific Results

The investigators have performed this same stress test on numerous subjects. In every case, they noticed the facial region cool down by between three and six degrees.

My nose dropped in heat by a small amount, as my physiological mechanism shifted blood distribution from my nasal region and to my eyes and ears – a physical reaction to help me to look and listen for danger.

Nearly all volunteers, like me, bounced back rapidly; their facial temperatures rose to normal readings within a few minutes.

Lead researcher explained that being a reporter and broadcaster has probably made me "relatively adapted to being put in tense situations".

"You're accustomed to the filming device and talking with unknown individuals, so it's probable you're somewhat resistant to social stressors," the scientist clarified.

"Nevertheless, even people with your background, trained to be tense circumstances, shows a bodily response alteration, so this indicates this 'nose temperature drop' is a robust marker of a changing stress state."

Anxiety Control Uses

Stress is part of life. But this revelation, the scientists say, could be used to aid in regulating damaging amounts of anxiety.

"The duration it takes someone to recover from this nasal dip could be an quantifiable indicator of how well an individual controls their anxiety," said the lead researcher.

"If they bounce back exceptionally gradually, could that be a warning sign of psychological issues? Is it something that we can address?"

Because this technique is without physical contact and measures a physical response, it could also be useful to monitor stress in babies or in individuals unable to express themselves.

The Calculation Anxiety Assessment

The subsequent challenge in my anxiety evaluation was, from my perspective, more challenging than the first. I was told to calculate backwards from 2023 in intervals of 17. One of the observers of three impassive strangers interrupted me each instance I made a mistake and told me to start again.

I acknowledge, I am poor with doing math in my head.

As I spent uncomfortable period trying to force my mind to execute arithmetic operations, all I could think 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 depart. The rest, like me, completed their tasks – presumably feeling varying degrees of humiliation – and were given an additional relaxation period of background static through audio devices at the conclusion.

Non-Human Applications

Perhaps one of the most surprising aspects of the approach is that, because thermal cameras monitor physiological anxiety indicators that is natural to numerous ape species, it can also be used in other species.

The scientists are presently creating its use in habitats for large monkeys, such as chimps and gorillas. They aim to determine how to reduce stress and improve the wellbeing of primates that may have been rescued from traumatic circumstances.

The team has already found that presenting mature chimps visual content of infant chimps has a calming effect. When the researchers set up a video screen adjacent to the rescued chimps' enclosure, they observed the nasal areas of animals that watched the material increase in temperature.

Consequently, concerning tension, watching baby animals interacting is the contrary to a spontaneous career evaluation or an on-the-spot subtraction task.

Coming Implementations

Employing infrared imaging in primate refuges could demonstrate itself as valuable in helping rehabilitated creatures to adapt and acclimate to a different community and strange surroundings.
