When I was asked to present an off-the-cuff short talk and then subtract sequentially in steps of 17 – all in front of a group of unfamiliar people – the acute stress was written on my face.

The reason was that researchers were filming this quite daunting situation for a scientific study that is examining tension using thermal cameras.

Stress alters the blood distribution in the countenance, and researchers have found that the drop in temperature of a person's nose can be used as a indicator of tension and to observe restoration.

Thermal imaging, based on researcher findings behind the study could be a "game changer" in anxiety studies.

The Experimental Stress Test

The scientific tension assessment that I underwent is meticulously designed and purposely arranged to be an discomforting experience. I came to the research facility with no idea what I was facing.

Initially, I was instructed to position myself, unwind and listen to white noise through a set of headphones.

Thus far, quite relaxing.

Then, the scientist who was running the test introduced a group of unfamiliar people into the space. They each looked at me without speaking as the investigator stated that I now had three minutes to create a brief presentation about my "perfect occupation".

As I felt the temperature increase around my neck, the scientists captured my complexion altering through their infrared device. My nose quickly dropped in temperature – showing colder on the infrared display – as I considered how to bluster my way through this unplanned presentation.

Scientific Results

The investigators have performed this same stress test on multiple participants. In each, they noticed the facial region cool down by several degrees.

My nose dropped in heat by two degrees, as my physiological mechanism shifted blood distribution from my face and to my sensory systems – a physical reaction to help me to see and detect for threats.

Most participants, similar to myself, returned to normal swiftly; their facial temperatures rose to baseline measurements within a brief period.

Head scientist explained that being a reporter and broadcaster has probably made me "somewhat accustomed to being placed in stressful positions".

"You're familiar with the camera and speaking to unfamiliar people, so it's probable you're quite resilient to interpersonal pressures," she explained.

"But even someone like you, experienced in handling tense circumstances, shows a biological blood flow shift, so that suggests this 'facial cooling' is a consistent measure of a shifting anxiety level."

Anxiety Control Uses

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

"The duration it takes an individual to bounce back from this nasal dip could be an quantifiable indicator of how well a person manages their stress," noted the head scientist.

"When they return exceptionally gradually, might this suggest a potential indicator of psychological issues? Could this be a factor that we can tackle?"

Since this method is non-intrusive and records biological reactions, it could additionally prove valuable to track anxiety in babies or in those with communication challenges.

The Calculation Anxiety Assessment

The subsequent challenge in my stress assessment was, from my perspective, more challenging than the opening task. I was instructed to subtract backwards from 2023 in intervals of 17. A member of the group of three impassive strangers stopped me every time I made a mistake and instructed me to start again.

I admit, I am poor with mental arithmetic.

During the uncomfortable period attempting to compel my thinking to accomplish mathematical calculations, my sole consideration was that I desired to escape the progressively tense environment.

Throughout the study, just a single of the 29 volunteers for the stress test did truly seek to exit. The others, like me, accomplished their challenges – probably enduring varying degrees of humiliation – and were rewarded with an additional relaxation period of background static through headphones at the end.

Primate Study Extensions

Perhaps one of the most remarkable features of the method is that, since infrared imaging measure a physical stress response that is innate in various monkey types, it can additionally be applied in non-human apes.

The researchers are currently developing its use in refuges for primates, such as chimps and gorillas. They want to work out how to decrease anxiety and boost the health of primates that may have been removed from harmful environments.

Scientists have earlier determined that displaying to grown apes video footage of baby chimpanzees has a calming effect. When the scientists installed a display monitor near the protected apes' living area, they noticed the facial regions of primates that viewed the material warm up.

So, in terms of stress, viewing infant primates playing is the contrary to a spontaneous career evaluation or an impromptu mathematical challenge.

Coming Implementations

Using thermal cameras in monkey habitats could prove to be useful for assisting rehabilitated creatures to become comfortable to a different community and strange surroundings.
