Mental Arithmetic Really Makes Me Tense and Science Has Proved It

Upon being told to deliver an unprepared five-minute speech and then count backwards in steps of 17 – all in front of a group of unfamiliar people – the acute stress was written on my face.

This occurred since researchers were filming this somewhat terrifying situation for a research project that is studying stress using infrared imaging.

Stress alters the circulation in the countenance, and researchers have found that the drop in temperature of a subject's face can be used as a gauge of anxiety and to track recuperation.

Heat mapping, based on researcher findings conducting the research could be a "revolutionary development" in tension analysis.

The Experimental Stress Test

The research anxiety evaluation that I participated in is meticulously designed and deliberately designed to be an discomforting experience. I came to the research facility with minimal awareness what I was in for.

Initially, I was told to settle, relax and listen to background static through a pair of earphones.

Thus far, quite relaxing.

Then, the investigator who was running the test invited a panel of three strangers into the room. They collectively gazed at me without speaking as the scientist explained that I now had a brief period to develop a five minute speech about my "dream job".

As I felt the heat rise around my collar area, the scientists captured my face changing colour through their thermal camera. My facial temperature immediately decreased in heat – showing colder on the thermal image – as I thought about how to manage this unplanned presentation.

Study Outcomes

The scientists have performed this equivalent anxiety evaluation on 29 volunteers. In every case, they observed the nasal area cool down by a noticeable amount.

My nasal area cooled in heat by a small amount, as my nervous system pushed blood flow away from my face and to my sensory systems – a physical reaction to assist me in see and detect for hazards.

Nearly all volunteers, like me, returned to normal swiftly; their noses warmed to normal readings within a short time.

Lead researcher stated that being a journalist and presenter has probably made me "quite habituated to being put in tense situations".

"You're familiar with the filming device and conversing with strangers, so you're likely relatively robust to interpersonal pressures," the researcher noted.

"Nevertheless, even people with your background, experienced in handling tense circumstances, exhibits a biological blood flow shift, so this indicates this 'nose temperature drop' is a robust marker of a altering tension condition."

Stress Management Applications

Anxiety is natural. But this discovery, the researchers state, could be used to aid in regulating damaging amounts of stress.

"The period it takes someone to recover from this cooling effect could be an objective measure of how efficiently a person manages their stress," noted the lead researcher.

"Should they recover remarkably delayed, could that be a warning sign of anxiety or depression? Could this be a factor that we can address?"

Because this technique is non-intrusive and measures a physical response, it could also be useful to track anxiety in babies or in those with communication challenges.

The Calculation Anxiety Assessment

The second task in my anxiety evaluation was, from my perspective, more challenging than the initial one. I was told to calculate in reverse starting from 2023 in intervals of 17. A member of the group of expressionless people stopped me each instance I committed an error and asked me to start again.

I confess, I am bad at calculating mentally.

As I spent awkward duration striving to push my thinking to accomplish subtraction, the only thought was that I desired to escape the increasingly stuffy room.

In the course of the investigation, just a single of the 29 volunteers for the anxiety assessment did truly seek to depart. The rest, like me, accomplished their challenges – probably enduring different levels of embarrassment – and were rewarded with an additional relaxation period of ambient sound through audio devices at the end.

Animal Research Applications

Maybe among the most remarkable features of the approach is that, as heat-sensing technology record biological tension reactions that is innate in many primates, it can also be used in animal primates.

The investigators are actively working on its use in sanctuaries for great apes, such as chimps and gorillas. They want to work out how to lower tension and improve the wellbeing of primates that may have been saved from harmful environments.

Scientists have earlier determined that showing adult chimpanzees video footage of infant chimps has a soothing influence. When the researchers set up a display monitor near the rehabilitated primates' habitat, they observed the nasal areas of primates that viewed the footage heat up.

Therefore, regarding anxiety, observing young creatures engaging in activities is the inverse of a unexpected employment assessment or an on-the-spot subtraction task.

Future Applications

Implementing heat-sensing technology in primate refuges could turn out to be useful for assisting rehabilitated creatures to adjust and settle in to a new social group and strange surroundings.
