Performing Calculations Mentally Truly Stresses Me Out and Studies Demonstrate This

When I was asked to give an impromptu short talk and then calculate in reverse in steps of 17 – while facing a trio of unknown individuals – the sudden tension was written on my face.

That is because scientists were recording this rather frightening experience for a research project that is examining tension using thermal cameras.

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

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

The Scientific Tension Assessment

The experimental stress test that I participated in is carefully controlled and deliberately designed to be an discomforting experience. I arrived at the academic institution with minimal awareness what I was about to experience.

First, I was instructed to position myself, calm down and listen to white noise through a audio headset.

Thus far, quite relaxing.

Then, the investigator who was conducting the experiment brought in a group of unfamiliar people into the room. They collectively gazed at me quietly as the scientist explained that I now had 180 seconds to develop a five minute speech about my "ideal career".

While experiencing the heat rise around my collar area, the scientists captured my complexion altering through their infrared device. My nose quickly dropped in heat – showing colder on the thermal image – as I contemplated ways to manage this spontaneous talk.

Research Findings

The investigators have carried out this identical tension assessment on numerous subjects. In each, they observed the nasal area cool down by a noticeable amount.

My nasal area cooled in temperature by a couple of degrees, as my physiological mechanism shifted blood distribution from my nose and to my eyes and ears – a bodily response to help me to observe and hear for hazards.

Most participants, similar to myself, bounced back rapidly; their noses warmed to pre-stressed levels within a brief period.

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

"You're familiar with the recording equipment and speaking to unfamiliar people, so you're probably quite resilient to social stressors," the scientist clarified.

"But even someone like you, trained to be tense circumstances, demonstrates a physiological circulation change, so this indicates this 'nose temperature drop' is a robust marker of a shifting anxiety level."

Anxiety Control Uses

Stress is part of life. But this discovery, the experts claim, could be used to help manage negative degrees of stress.

"The length of time it takes an individual to bounce back from this cooling effect could be an objective measure of how well an individual controls their stress," explained the head scientist.

"If they bounce back exceptionally gradually, could that be a warning sign of psychological issues? Is it something that we can tackle?"

Because this technique is non-intrusive and measures a physical response, it could also be useful to monitor stress in infants or in individuals unable to express themselves.

The Mathematical Stress Test

The following evaluation in my stress assessment was, in my view, more difficult than the first. I was instructed to subtract in reverse starting from 2023 in steps of 17. One of the observers of unresponsive individuals halted my progress each instance I calculated incorrectly and instructed me to recommence.

I acknowledge, I am poor with calculating mentally.

While I used uncomfortable period striving to push my brain to perform arithmetic operations, all I could think was that I desired to escape the progressively tense environment.

Throughout the study, only one of the multiple participants for the anxiety assessment did truly seek to exit. The rest, like me, completed their tasks – presumably feeling assorted amounts of discomfort – and were rewarded with another calming session of white noise through audio devices at the end.

Animal Research Applications

Perhaps one of the most remarkable features of the approach is that, because thermal cameras monitor physiological anxiety indicators that is inherent within various monkey types, it can additionally be applied in animal primates.

The researchers are presently creating its implementation within refuges for primates, such as chimps and gorillas. They seek to establish how to reduce stress and boost the health of animals that may have been rescued from harmful environments.

Scientists have earlier determined that presenting mature chimps video footage of baby chimpanzees has a relaxing impact. When the researchers set up a video screen near the rehabilitated primates' habitat, they observed the nasal areas of animals that watched the content warm up.

So, in terms of stress, observing young creatures engaging in activities is the inverse of a surprise job interview or an on-the-spot subtraction task.

Future Applications

Using thermal cameras in monkey habitats could prove to be beneficial in supporting protected primates to become comfortable to a unfamiliar collective and unfamiliar environment.
