After being requested to present an off-the-cuff brief presentation and then calculate in reverse in steps of 17 – before a group of unfamiliar people – the acute stress was visible in my features.

That is because psychologists were filming this somewhat terrifying scenario for a scientific study that is studying stress using heat-sensing technology.

Tension changes the blood distribution in the face, and researchers have found that the cooling effect of a person's nose can be used as a measure of stress levels and to observe restoration.

Infrared technology, as stated by the scientists conducting the research could be a "game changer" in stress research.

The Scientific Tension Assessment

The experimental stress test that I subjected myself to is precisely structured and purposely arranged to be an unexpected challenge. I visited the university with minimal awareness what I was about to experience.

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

Up to this point, very peaceful.

Afterward, the scientist who was overseeing the assessment brought in a group of unfamiliar people into the area. They each looked at me quietly as the scientist explained that I now had three minutes to develop a five minute speech about my "ideal career".

When noticing the temperature increase around my neck, the researchers recorded my face changing colour through their heat-sensing equipment. My facial temperature immediately decreased in warmth – turning blue on the infrared display – as I thought about how to manage this impromptu speech.

Scientific Results

The scientists have conducted this equivalent anxiety evaluation on multiple participants. In all instances, they saw their nose dip in temperature by a noticeable amount.

My nasal area cooled in temperature by a couple of degrees, as my biological response system shifted blood distribution from my nasal region and to my sensory systems – a bodily response to enable me to observe and hear for hazards.

The majority of subjects, similar to myself, bounced back rapidly; their noses warmed to normal readings within a brief period.

Head scientist noted that being a journalist and presenter has probably made me "somewhat accustomed to being placed in stressful positions".

"You're familiar with the camera and talking with unknown individuals, so it's probable you're relatively robust to interpersonal pressures," the scientist clarified.

"But even someone like you, trained to be tense circumstances, exhibits a bodily response alteration, so which implies this 'nasal dip' is a reliable indicator of a changing stress state."

Tension Regulation Possibilities

Anxiety is natural. But this revelation, the experts claim, could be used to aid in regulating harmful levels of tension.

"The period it takes a person to return to normal from this cooling effect could be an reliable gauge of how efficiently a person manages their stress," explained the lead researcher.

"If they bounce back remarkably delayed, could this indicate a risk marker of anxiety or depression? Is it something that we can do anything about?"

Because this technique is without physical contact and records biological reactions, it could also be useful to observe tension in newborns or in those with communication challenges.

The Calculation Anxiety Assessment

The second task in my stress assessment was, from my perspective, even worse than the initial one. I was instructed to subtract in reverse starting from 2023 in increments of seventeen. One of the observers of unresponsive individuals stopped me each instance I committed an error and asked me to start again.

I acknowledge, I am poor with calculating mentally.

As I spent uncomfortable period attempting to compel my brain to perform mathematical calculations, the only thought was that I wanted to flee the growing uncomfortable space.

Throughout the study, merely one of the numerous subjects for the stress test did actually ask to depart. The remainder, like me, finished their assignments – likely experiencing varying degrees of discomfort – and were given a further peaceful interval of ambient sound through headphones at the end.

Primate Study Extensions

Maybe among the most surprising aspects of the technique is that, as heat-sensing technology monitor physiological anxiety indicators that is innate in various monkey types, it can additionally be applied in other species.

The investigators are actively working on its implementation within refuges for primates, including chimpanzees and gorillas. They seek to establish how to lower tension and improve the wellbeing of animals that may have been removed from harmful environments.

Researchers have previously discovered that displaying to grown apes video footage of baby chimpanzees has a relaxing impact. When the investigators placed a visual device adjacent to the rehabilitated primates' habitat, they observed the nasal areas of animals that watched the content heat up.

Consequently, concerning tension, viewing infant primates engaging in activities is the inverse of a unexpected employment assessment or an impromptu mathematical challenge.

Future Applications

Using thermal cameras in ape sanctuaries could prove to be beneficial in supporting rehabilitated creatures to adjust and settle in to a unfamiliar collective and unknown territory.
