Performing Calculations Mentally Truly Causes Me Anxiety and Research Confirms It

Upon being told to give an impromptu five-minute speech and then subtract sequentially in intervals of 17 – all in front of a trio of unknown individuals – the intense pressure was visible in my features.

This occurred since researchers were filming this quite daunting situation for a investigation that is examining tension using heat-sensing technology.

Tension changes the blood flow in the countenance, and researchers have found that the thermal decrease of a subject's face can be used as a gauge of anxiety and to observe restoration.

Infrared technology, based on researcher findings leading the investigation could be a "transformative advancement" in tension analysis.

The Experimental Stress Test

The scientific tension assessment that I underwent is carefully controlled and purposely arranged to be an discomforting experience. I visited the university with little knowledge what I was about to experience.

Initially, I was instructed to position myself, unwind and experience white noise through a pair of earphones.

Thus far, quite relaxing.

Afterward, the investigator who was overseeing the assessment introduced a group of unfamiliar people into the room. They all stared at me without speaking as the scientist explained that I now had a brief period to create a five minute speech about my "ideal career".

When noticing the temperature increase around my neck, the scientists captured my skin tone shifting through their heat-sensing equipment. My facial temperature immediately decreased in temperature – appearing cooler on the heat map – as I contemplated ways to bluster my way through this unplanned presentation.

Research Findings

The investigators have carried out this equivalent anxiety evaluation on 29 volunteers. In all instances, they observed the nasal area cool down by several degrees.

My nasal area cooled in temperature by two degrees, as my nervous system shifted blood distribution from my nose and to my visual and auditory organs – a physiological adaptation to help me to see and detect for danger.

Nearly all volunteers, like me, returned to normal swiftly; their facial temperatures rose to pre-stressed levels within a short time.

Head scientist noted that being a reporter and broadcaster has probably made me "relatively adapted to being put in anxiety-provoking circumstances".

"You're accustomed to the filming device and speaking to strangers, so it's probable you're somewhat resistant to public speaking anxieties," the scientist clarified.

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

Anxiety Control Uses

Tension is inevitable. But this finding, the researchers state, could be used to assist in controlling harmful levels of tension.

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

"Should they recover unusually slowly, could that be a warning sign of psychological issues? Is it something that we can address?"

Since this method is without physical contact and monitors physiological changes, it could also be useful to observe tension in infants or in those with communication challenges.

The Mathematical Stress Test

The following evaluation in my anxiety evaluation was, from my perspective, more challenging than the initial one. I was asked to count in reverse starting from 2023 in intervals of 17. One of the observers of three impassive strangers halted my progress each instance I made a mistake and asked me to begin anew.

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

During the embarrassing length of time striving to push my thinking to accomplish subtraction, the only thought was that I wanted to flee the growing uncomfortable space.

During the research, merely one of the multiple participants for the stress test did genuinely request to leave. The rest, comparable to my experience, finished their assignments – probably enduring different levels of humiliation – and were given an additional relaxation period of white noise through headphones at the finish.

Animal Research Applications

Maybe among the most surprising aspects of the method is that, because thermal cameras record biological tension reactions that is innate in many primates, it can furthermore be utilized in animal primates.

The researchers are currently developing its application in refuges for primates, comprising various ape species. They aim to determine how to lower tension and improve the wellbeing of primates that may have been saved from traumatic circumstances.

Researchers have previously discovered that presenting mature chimps visual content of young primates has a relaxing impact. When the investigators placed a visual device near the rehabilitated primates' habitat, they saw the noses of creatures that observed the content heat up.

So, in terms of stress, viewing infant primates engaging in activities is the inverse of a surprise job interview or an impromptu mathematical challenge.

Potential Uses

Implementing heat-sensing technology in ape sanctuaries could turn out to be useful for assisting rehabilitated creatures to adjust and settle in to a unfamiliar collective and strange surroundings.
