Upon being told to present an off-the-cuff short talk and then calculate in reverse in increments of seventeen – all in front of a trio of unknown individuals – the sudden tension was evident in my expression.

This occurred since psychologists were documenting this quite daunting scenario for a scientific study that is examining tension using thermal cameras.

Stress alters the circulation in the facial area, and experts have determined that the drop in temperature of a subject's face can be used as a gauge of anxiety and to monitor recovery.

Thermal imaging, according to the psychologists leading the investigation could be a "revolutionary development" in anxiety studies.

The Scientific Tension Assessment

The experimental stress test that I subjected myself to is carefully controlled and intentionally created to be an unexpected challenge. I visited the academic institution with no idea what I was in for.

Initially, I was instructed to position myself, relax and experience white noise through a audio headset.

So far, so calming.

Subsequently, the investigator who was conducting the experiment brought in a trio of unknown individuals into the space. They collectively gazed at me without speaking as the investigator stated that I now had three minutes to prepare a five minute speech about my "perfect occupation".

As I felt the temperature increase around my neck, the scientists captured my skin tone shifting through their heat-sensing equipment. My nasal area rapidly cooled in warmth – appearing cooler on the infrared display – as I contemplated ways to bluster my way through this unplanned presentation.

Research Findings

The researchers have carried out this same stress test on numerous subjects. In every case, they saw their nose cool down by a noticeable amount.

My nasal area cooled in heat by a small amount, as my physiological mechanism pushed blood flow away from my nasal region and to my eyes and ears – a physical reaction to enable me to see and detect for hazards.

Nearly all volunteers, similar to myself, recovered quickly; their noses warmed to baseline measurements within a brief period.

Lead researcher explained that being a journalist and presenter has probably made me "somewhat accustomed to being subjected to anxiety-provoking circumstances".

"You are used to the camera and talking with strangers, so you're likely relatively robust to interpersonal pressures," the scientist clarified.

"But even someone like you, accustomed to being tense circumstances, demonstrates a biological blood flow shift, so that suggests this 'facial cooling' is a reliable indicator of a changing stress state."

Stress Management Applications

Stress is part of life. But this discovery, the experts claim, could be used to help manage negative degrees of anxiety.

"The duration it takes someone to recover from this nasal dip could be an reliable gauge of how efficiently an individual controls their tension," explained the head scientist.

"Should they recover unusually slowly, might this suggest a potential indicator of anxiety or depression? Could this be a factor that we can tackle?"

As this approach is non-intrusive and monitors physiological changes, it could additionally prove valuable to monitor stress in infants or in individuals unable to express themselves.

The Calculation Anxiety Assessment

The subsequent challenge in my anxiety evaluation was, in my view, more challenging than the initial one. I was instructed to subtract sequentially decreasing from 2023 in steps of 17. One of the observers of three impassive strangers interrupted me every time I calculated incorrectly and told me to recommence.

I confess, I am inexperienced in mental arithmetic.

During the uncomfortable period attempting to compel my mind to execute mathematical calculations, my sole consideration was that I wished to leave the increasingly stuffy room.

Throughout the study, only one of the 29 volunteers for the stress test did truly seek to depart. The rest, similar to myself, accomplished their challenges – likely experiencing assorted amounts of discomfort – and were given an additional relaxation period of white noise through headphones at the finish.

Animal Research Applications

Possibly included in the most unexpected elements of the technique is that, since infrared imaging measure a physical stress response that is natural to many primates, it can also be used in animal primates.

The investigators are actively working on its use in sanctuaries for great apes, including chimpanzees and gorillas. They want to work out how to reduce stress and enhance the welfare of animals that may have been saved from distressing situations.

Researchers have previously discovered that displaying to grown apes video footage of infant chimps has a soothing influence. When the investigators placed a visual device near the protected apes' living area, they noticed the facial regions of primates that viewed the footage warm up.

So, in terms of stress, viewing infant primates playing is the contrary to a surprise job interview or an impromptu mathematical challenge.

Potential Uses

Implementing heat-sensing technology in monkey habitats could prove to be beneficial in supporting rehabilitated creatures to become comfortable to a unfamiliar collective and unfamiliar environment.
