Upon being told to present an off-the-cuff short talk and then subtract sequentially in steps of 17 – while facing a panel of three strangers – the intense pressure was evident in my expression.

This occurred since scientists were recording this somewhat terrifying situation for a scientific study that is examining tension using thermal cameras.

Tension changes the blood distribution in the countenance, and scientists have discovered that the drop in temperature of a individual's nasal area can be used as a indicator of tension and to track recuperation.

Infrared technology, based on researcher findings conducting the research could be a "game changer" in stress research.

The Experimental Stress Test

The scientific tension assessment that I underwent is carefully controlled and deliberately designed to be an unexpected challenge. I arrived at the research facility with no idea what I was about to experience.

First, I was told to settle, calm down and hear ambient sound through a set of headphones.

So far, so calming.

Afterward, the researcher who was running the test invited a trio of unknown individuals into the room. They each looked at me quietly as the scientist explained that I now had three minutes to prepare a brief presentation about my "perfect occupation".

While experiencing the temperature increase around my collar area, the experts documented my complexion altering through their heat-sensing equipment. My facial temperature immediately decreased in warmth – turning blue on the thermal image – as I considered how to navigate this impromptu speech.

Research Findings

The scientists have conducted this equivalent anxiety evaluation on 29 volunteers. In every case, they noticed the facial region decrease in warmth by between three and six degrees.

My nasal area cooled in warmth by a couple of degrees, as my physiological mechanism redirected circulation from my nasal region and to my visual and auditory organs – a physiological adaptation to enable me to see and detect for threats.

Most participants, comparable to my experience, recovered quickly; their noses warmed to pre-stressed levels within a short time.

Head scientist explained that being a journalist and presenter has probably made me "relatively adapted to being put in anxiety-provoking circumstances".

"You're accustomed to the recording equipment and conversing with unknown individuals, so it's probable you're relatively robust to interpersonal pressures," the researcher noted.

"But even someone like you, accustomed to being stressful situations, shows a biological blood flow shift, so this indicates this 'nose temperature drop' is a consistent measure of a altering tension condition."

Stress Management Applications

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

"The period it takes a person to return to normal from this cooling effect could be an quantifiable indicator of how effectively an individual controls their tension," said the lead researcher.

"If they bounce back remarkably delayed, could this indicate a risk marker of mental health concerns? Could this be a factor that we can do anything about?"

As this approach is non-invasive and monitors physiological changes, it could furthermore be beneficial to observe tension in newborns or in people who can't communicate.

The Mathematical Stress Test

The second task in my stress assessment was, personally, more challenging than the initial one. I was told to calculate in reverse starting from 2023 in steps of 17. Someone on the panel of three impassive strangers stopped me each instance I calculated incorrectly and asked me to begin anew.

I confess, I am bad at calculating mentally.

During the awkward duration striving to push my thinking to accomplish subtraction, all I could think was that I wished to leave the increasingly stuffy room.

During the research, only one of the multiple participants for the tension evaluation did truly seek to leave. The remainder, comparable to my experience, completed their tasks – presumably feeling different levels of humiliation – and were given a further peaceful interval of background static through audio devices at the end.

Non-Human Applications

Maybe among the most surprising aspects of the method is that, as heat-sensing technology measure a physical stress response that is inherent within numerous ape species, it can additionally be applied in non-human apes.

The scientists are presently creating its implementation within sanctuaries for great apes, including chimpanzees and gorillas. They aim to determine how to lower tension and improve the wellbeing of primates that may have been saved from traumatic circumstances.

Scientists have earlier determined that presenting mature chimps video footage of baby chimpanzees has a calming effect. When the investigators placed a display monitor near the rehabilitated primates' habitat, they noticed the facial regions of primates that viewed the footage increase in temperature.

So, in terms of stress, viewing infant primates playing is the inverse of a unexpected employment assessment or an spontaneous calculation test.

Coming Implementations

Employing infrared imaging in monkey habitats could turn out to be useful for assisting protected primates to adapt and acclimate to a new social group and strange surroundings.
