Mental Arithmetic Truly Makes Me Tense and Science Has Proved It

After being requested to present an off-the-cuff five-minute speech and then calculate in reverse in steps of 17 – while facing a group of unfamiliar people – the sudden tension was visible in my features.

That is because scientists were filming this somewhat terrifying scenario for a scientific study that is analyzing anxiety using heat-sensing technology.

Tension changes the circulation in the face, and scientists have discovered that the cooling effect of a subject's face can be used as a indicator of tension and to monitor recovery.

Heat mapping, as stated by the scientists behind the study could be a "game changer" in tension analysis.

The Scientific Tension Assessment

The experimental stress test that I participated in is carefully controlled and intentionally created to be an discomforting experience. I visited the university with minimal awareness what I was about to experience.

Initially, I was asked to sit, calm down and hear background static through a set of headphones.

Up to this point, very peaceful.

Then, the researcher who was overseeing the assessment brought in a group of unfamiliar people into the space. They each looked 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".

As I felt the temperature increase around my throat, the researchers recorded my complexion altering through their infrared device. My nose quickly dropped in temperature – appearing cooler on the thermal image – as I thought about how to manage this impromptu speech.

Scientific Results

The scientists have performed this identical tension assessment on 29 volunteers. In every case, they saw their nose decrease in warmth by between three and six degrees.

My nose dropped in temperature 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 enable me to see and detect for danger.

Most participants, like me, recovered quickly; their facial temperatures rose to pre-stressed levels within a few minutes.

Principal investigator noted that being a media professional has probably made me "somewhat accustomed to being put in tense situations".

"You are used to the recording equipment and speaking to strangers, so you're probably somewhat resistant to public speaking anxieties," she explained.

"Nevertheless, even people with your background, experienced in handling anxiety-provoking scenarios, demonstrates a physiological circulation change, so this indicates this 'nose temperature drop' is a robust marker of a altering tension condition."

Stress Management Applications

Stress is part of life. But this finding, the scientists say, could be used to help manage negative degrees of stress.

"The length of time it takes someone to recover from this temperature drop could be an quantifiable indicator of how efficiently somebody regulates their tension," explained the principal investigator.

"When they return exceptionally gradually, could that be a warning sign of anxiety or depression? Is it something that we can tackle?"

Because this technique is non-invasive and records biological reactions, it could furthermore be beneficial to monitor stress in newborns or in individuals unable to express themselves.

The Calculation Anxiety Assessment

The subsequent challenge in my tension measurement was, from my perspective, even worse than the initial one. I was told to calculate sequentially decreasing from 2023 in increments of seventeen. A member of the group of expressionless people stopped me every time I committed an error and instructed me to recommence.

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

As I spent uncomfortable period attempting to compel my mind to execute mathematical calculations, my sole consideration was that I desired to escape the growing uncomfortable space.

In the course of the investigation, merely one of the numerous subjects for the tension evaluation did genuinely request to depart. The rest, comparable to my experience, accomplished their challenges – likely experiencing different levels of humiliation – and were given an additional relaxation period of white noise through audio devices at the conclusion.

Animal Research Applications

Maybe among the most remarkable features of the method is that, because thermal cameras measure a physical stress response that is inherent within numerous ape species, it can additionally be applied in non-human apes.

The researchers are presently creating its implementation within habitats for large monkeys, including chimpanzees and gorillas. They seek to establish how to reduce stress and boost the health of creatures that may have been rescued from harmful environments.

The team has already found that showing adult chimpanzees visual content of infant chimps has a soothing influence. When the investigators placed a video screen adjacent to the rescued chimps' enclosure, they saw the noses of primates that viewed the content heat up.

Therefore, regarding anxiety, watching baby animals playing is the opposite of a surprise job interview or an impromptu mathematical challenge.

Future Applications

Using thermal cameras in monkey habitats could turn out to be beneficial in supporting protected primates to adapt and acclimate to a different community and unknown territory.
