After being requested to present an off-the-cuff five-minute speech and then count backwards in steps of 17 – while facing a trio of unknown individuals – the sudden tension was written on my face.

That is because scientists were filming this quite daunting situation for a research project that is examining tension using infrared imaging.

Anxiety modifies the blood flow in the face, and experts have determined that the drop in temperature of a individual's nasal area can be used as a indicator of tension and to monitor recovery.

Infrared technology, according to the psychologists behind the study could be a "revolutionary development" in stress research.

The Scientific Tension Assessment

The experimental stress test that I subjected myself to is meticulously designed and intentionally created to be an unpleasant surprise. I arrived at the research facility with little knowledge what I was facing.

Initially, I was asked to sit, calm down and listen to white noise through a pair of earphones.

So far, so calming.

Afterward, the investigator who was running the test introduced a group of unfamiliar people into the area. They each looked at me silently as the scientist explained that I now had 180 seconds to create a brief presentation about my "ideal career".

When noticing the warmth build around my neck, the experts documented my complexion altering through their heat-sensing equipment. My facial temperature immediately decreased in heat – appearing cooler on the thermal image – as I thought about how to bluster my way through this spontaneous talk.

Research Findings

The researchers have conducted this same stress test on multiple participants. In every case, they observed the nasal area decrease in warmth by several degrees.

My facial temperature decreased in heat by a couple of degrees, as my nervous system pushed blood flow away from my nose and to my eyes and ears – a physiological adaptation to help me to observe and hear for danger.

Nearly all volunteers, similar to myself, recovered quickly; their facial temperatures rose to baseline measurements within a few minutes.

Head scientist noted that being a reporter and broadcaster has probably made me "relatively adapted to being placed in stressful positions".

"You're accustomed to the recording equipment and conversing with strangers, so it's probable you're relatively robust to interpersonal pressures," the scientist clarified.

"However, even individuals such as yourself, experienced in handling tense circumstances, shows a biological blood flow shift, so that suggests this 'nose temperature drop' is a reliable indicator of a shifting anxiety level."

Tension Regulation Possibilities

Tension is inevitable. But this discovery, the researchers state, could be used to aid in regulating harmful levels of anxiety.

"The length of time it takes an individual to bounce back from this nasal dip could be an quantifiable indicator of how well an individual controls their anxiety," noted the principal investigator.

"If they bounce back unusually slowly, could this indicate a potential indicator of mental health concerns? Could this be a factor that we can do anything about?"

As this approach is without physical contact and records biological reactions, it could additionally prove valuable to monitor stress in babies or in individuals unable to express themselves.

The Calculation Anxiety Assessment

The second task in my stress assessment was, in my view, even worse than the opening task. I was told to calculate in reverse starting from 2023 in steps of 17. Someone on the panel of expressionless people interrupted me every time I calculated incorrectly and instructed me to recommence.

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

While I used embarrassing length of time attempting to compel my thinking to accomplish mathematical calculations, my sole consideration was that I desired to escape the progressively tense environment.

Throughout the study, only one of the 29 volunteers for the stress test did actually ask to exit. The rest, similar to myself, completed their tasks – presumably feeling assorted amounts of humiliation – and were compensated by an additional relaxation period of white noise through headphones at the conclusion.

Animal Research Applications

Maybe among the most unexpected elements of the technique is that, since infrared imaging monitor physiological anxiety indicators that is inherent within numerous ape species, it can additionally be applied in non-human apes.

The scientists are presently creating its implementation within refuges for primates, comprising various ape species. They seek to establish how to lower tension and improve the wellbeing of creatures that may have been removed from harmful environments.

Scientists have earlier determined that showing adult chimpanzees visual content of infant chimps has a relaxing impact. When the scientists installed a video screen adjacent to the rehabilitated primates' habitat, they noticed the facial regions of animals that watched the footage warm up.

So, in terms of stress, watching baby animals engaging in activities is the inverse of a spontaneous career evaluation or an on-the-spot subtraction task.

Potential Uses

Employing infrared imaging in ape sanctuaries could turn out to be useful for assisting protected primates to adjust and settle in to a unfamiliar collective and unknown territory.
