Upon being told to present an off-the-cuff short talk and then count backwards in intervals of 17 – before a trio of unknown individuals – the acute stress was visible in my features.

This occurred since researchers were documenting this somewhat terrifying situation for a investigation that is studying stress using infrared imaging.

Stress alters the circulation in the facial area, and scientists have discovered that the drop in temperature of a individual's nasal area can be used as a indicator of tension and to track recuperation.

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

The Scientific Tension Assessment

The scientific tension assessment that I underwent is carefully controlled and purposely arranged to be an unpleasant surprise. I visited the university with minimal awareness what I was about to experience.

First, I was told to settle, calm down and listen to white noise through a audio headset.

So far, so calming.

Afterward, the investigator who was conducting the experiment brought in a trio of unknown individuals into the space. They collectively gazed at me quietly as the researcher informed that I now had three minutes to create a short talk about my "dream job".

As I felt the warmth build around my throat, the scientists captured my skin tone shifting through their thermal camera. My nose quickly dropped in temperature – appearing cooler on the thermal image – as I considered how 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 noticed the facial region dip in temperature by between three and six degrees.

My nose dropped in heat by a small amount, as my nervous system shifted blood distribution from my face and to my visual and auditory organs – a physiological adaptation to assist me in look and listen for hazards.

Most participants, like me, bounced back rapidly; their nasal areas heated to normal readings within a few minutes.

Principal investigator stated that being a journalist and presenter has probably made me "quite habituated to being subjected to tense situations".

"You're familiar with the camera and speaking to unknown individuals, so you're probably somewhat resistant to interpersonal pressures," the researcher noted.

"However, even individuals such as yourself, accustomed to being stressful situations, demonstrates a physiological circulation change, so this indicates this 'nose temperature drop' is a consistent measure of a changing stress state."

Stress Management Applications

Anxiety is natural. But this revelation, the scientists say, could be used to help manage negative degrees of stress.

"The period it takes a person to return to normal from this cooling effect could be an objective measure of how well a person manages their stress," explained the head scientist.

"Should they recover remarkably delayed, could this indicate a potential indicator of psychological issues? Could this be a factor that we can address?"

Since this method is without physical contact and records biological reactions, it could also be useful to track anxiety in babies or in people who can't communicate.

The Calculation Anxiety Assessment

The following evaluation in my stress assessment was, personally, more difficult than the initial one. I was told to calculate in reverse starting from 2023 in intervals of 17. A member of the group of unresponsive individuals halted my progress whenever I made a mistake and instructed me to begin anew.

I confess, I am inexperienced in calculating mentally.

While I used uncomfortable period attempting to compel my brain to perform mathematical calculations, the only thought was that I desired to escape the progressively tense environment.

During the research, only one of the multiple participants for the anxiety assessment did genuinely request to leave. The remainder, similar to myself, completed their tasks – presumably feeling varying degrees of embarrassment – and were rewarded with another calming session of ambient sound through headphones at the finish.

Non-Human Applications

Possibly included in the most remarkable features of the method is that, since infrared imaging measure a physical stress response that is natural to various monkey types, it can furthermore be utilized in other species.

The researchers are currently developing its application in sanctuaries for great apes, comprising various ape species. They want to work out how to lower tension and improve the wellbeing of primates that may have been rescued from harmful environments.

Researchers have previously discovered that showing adult chimpanzees video footage of infant chimps has a relaxing impact. When the researchers set up a video screen near the protected apes' living area, they observed the nasal areas of animals that watched the footage heat up.

So, in terms of stress, viewing infant primates engaging in activities is the opposite of a spontaneous career evaluation or an impromptu mathematical challenge.

Future Applications

Using thermal cameras in primate refuges could turn out to be useful for assisting rescued animals to adapt and acclimate to a different community and strange surroundings.
