After being requested to present an off-the-cuff short talk and then subtract sequentially in steps of 17 – while facing a group of unfamiliar people – the sudden tension was written on my face.

The reason was that psychologists were documenting this somewhat terrifying scenario for a scientific study that is examining tension using infrared imaging.

Anxiety modifies the blood flow in the face, and experts have determined that the thermal decrease of a subject's face can be used as a measure of stress levels and to track recuperation.

Heat mapping, as stated by the scientists conducting the research could be a "revolutionary development" in tension analysis.

The Scientific Tension Assessment

The experimental stress test that I underwent is meticulously designed and purposely arranged to be an unexpected challenge. I arrived at the research facility with no idea what I was facing.

Initially, I was told to settle, calm down and experience white noise through a pair of earphones.

Up to this point, very peaceful.

Then, the researcher who was conducting the experiment brought in a trio of unknown individuals into the space. They collectively gazed at me without speaking as the scientist explained that I now had three minutes to prepare a short talk about my "dream job".

While experiencing the heat rise around my neck, the scientists captured my complexion altering through their thermal camera. My nose quickly dropped in temperature – turning blue on the heat map – as I contemplated ways to navigate this spontaneous talk.

Study Outcomes

The investigators have conducted this equivalent anxiety evaluation on multiple participants. In every case, they saw their nose cool down by between three and six degrees.

My nasal area cooled in temperature by a small amount, as my biological response system redirected circulation from my nasal region and to my sensory systems – a physiological adaptation to enable me to see and detect for danger.

Nearly all volunteers, similar to myself, recovered quickly; their noses warmed to baseline measurements within a brief period.

Lead researcher noted that being a journalist and presenter has probably made me "relatively adapted to being placed in anxiety-provoking circumstances".

"You're accustomed to the recording equipment and speaking to strangers, so it's probable you're relatively robust to interpersonal pressures," the scientist clarified.

"Nevertheless, even people with your background, accustomed to being tense circumstances, exhibits a physiological circulation change, so that suggests this 'nasal dip' is a robust marker of a changing stress state."

Tension Regulation Possibilities

Stress is part of life. But this revelation, the experts claim, could be used to help manage damaging amounts of stress.

"The duration it takes an individual to bounce back from this nasal dip could be an quantifiable indicator of how efficiently somebody regulates their anxiety," noted the principal investigator.

"When they return remarkably delayed, might this suggest a warning sign of psychological issues? Could this be a factor that we can address?"

Because this technique is without physical contact and monitors physiological changes, it could furthermore be beneficial to monitor stress in infants or in those with communication challenges.

The Calculation Anxiety Assessment

The following evaluation in my tension measurement was, in my view, more challenging than the initial one. I was told to calculate in reverse starting from 2023 in intervals of 17. Someone on the panel of expressionless people interrupted me each instance I committed an error and instructed me to recommence.

I confess, I am poor with mental arithmetic.

While I used uncomfortable period attempting to compel my brain to perform subtraction, the only thought was that I wanted to flee the increasingly stuffy room.

Throughout the study, merely one of the numerous subjects for the tension evaluation did actually ask to depart. The remainder, comparable to my experience, completed their tasks – presumably feeling varying degrees of humiliation – and were compensated by a further peaceful interval of background static through audio devices at the end.

Non-Human Applications

Maybe among the most surprising aspects of the approach is that, because thermal cameras record biological tension reactions that is inherent within many primates, it can additionally be applied in animal primates.

The scientists are actively working on its use in habitats for large monkeys, comprising various ape species. They seek to establish how to decrease anxiety and improve the wellbeing of creatures that may have been saved from harmful environments.

The team has already found that showing adult chimpanzees video footage of baby chimpanzees has a soothing influence. When the scientists installed a display monitor adjacent to the rescued chimps' enclosure, they saw the noses of animals that watched the content warm up.

Therefore, regarding anxiety, viewing infant primates engaging in activities is the contrary to a spontaneous career evaluation or an spontaneous calculation test.

Future Applications

Implementing heat-sensing technology in primate refuges could turn out to be beneficial in supporting protected primates to adapt and acclimate to a different community and unfamiliar environment.
