When I was asked to present an off-the-cuff brief presentation and then subtract sequentially in increments of seventeen – while facing a group of unfamiliar people – the intense pressure was evident in my expression.

That is because psychologists were recording this quite daunting scenario for a research project that is studying stress using heat-sensing technology.

Tension changes the blood flow in the facial area, and experts have determined that the thermal decrease of a person's nose can be used as a indicator of tension and to track recuperation.

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

The Scientific Tension Assessment

The research anxiety evaluation that I participated in is carefully controlled and purposely arranged to be an unexpected challenge. I arrived at the university with little knowledge what I was in for.

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

Thus far, quite relaxing.

Then, the scientist who was conducting the experiment brought in a panel of three strangers into the area. They all stared at me without speaking as the scientist explained that I now had three minutes to create a five minute speech about my "perfect occupation".

As I felt the temperature increase around my neck, the experts documented my skin tone shifting through their heat-sensing equipment. My facial temperature immediately decreased in temperature – turning blue on the infrared display – as I thought about how to navigate this impromptu speech.

Research Findings

The scientists have conducted this identical tension assessment on multiple participants. In every case, they saw their nose decrease in warmth by several degrees.

My nose dropped in temperature by two degrees, as my biological response system redirected circulation from my nose and to my visual and auditory organs – a physical reaction to help me to observe and hear for danger.

Most participants, similar to myself, bounced back rapidly; their noses warmed to normal readings within a brief period.

Principal investigator explained that being a reporter and broadcaster has probably made me "quite habituated to being put in anxiety-provoking circumstances".

"You are used to the recording equipment and speaking to strangers, so you're likely relatively robust to interpersonal pressures," the scientist clarified.

"However, even individuals such as yourself, accustomed to being stressful situations, demonstrates a bodily response alteration, so that suggests this 'nose temperature drop' is a consistent measure of a altering tension condition."

Tension Regulation Possibilities

Tension is inevitable. But this revelation, the scientists say, could be used to assist in controlling negative degrees of tension.

"The length of time it takes someone to recover from this cooling effect could be an quantifiable indicator of how well an individual controls their tension," explained the principal investigator.

"When they return unusually slowly, could that be a potential indicator of mental health concerns? Is it something that we can address?"

Since this method is without physical contact and records biological reactions, it could additionally prove valuable to monitor stress in newborns or in people who can't communicate.

The Mental Arithmetic Challenge

The following evaluation in my anxiety evaluation was, personally, even worse than the first. I was instructed to subtract backwards from 2023 in increments of seventeen. A member of the group of expressionless people halted my progress each instance I calculated incorrectly and instructed me to recommence.

I confess, I am bad at doing math in my head.

During the awkward duration trying to force my mind to execute mathematical calculations, the only thought was that I wished to leave the progressively tense environment.

Throughout the study, merely one of the numerous subjects for the stress test did actually ask to leave. The remainder, similar to myself, finished their assignments – likely experiencing different levels of humiliation – and were given another calming session of ambient sound through headphones at the finish.

Animal Research Applications

Perhaps one of the most unexpected elements of the method is that, as heat-sensing technology record biological tension reactions that is inherent within many primates, it can furthermore be utilized in other species.

The researchers are currently developing its implementation within sanctuaries for great apes, including chimpanzees and gorillas. They seek to establish how to reduce stress and improve the wellbeing of primates that may have been saved from traumatic circumstances.

The team has already found that displaying to grown apes video footage of infant chimps has a calming effect. When the investigators placed a visual device close to the rehabilitated primates' habitat, they noticed the facial regions of creatures that observed the content warm up.

Therefore, regarding anxiety, watching baby animals engaging in activities is the opposite of a spontaneous career evaluation or an impromptu mathematical challenge.

Potential Uses

Implementing heat-sensing technology in primate refuges could turn out to be beneficial in supporting rescued animals to adapt and acclimate to a different community and unfamiliar environment.
