When I was asked to deliver an unprepared brief presentation and then calculate in reverse in intervals of 17 – before a group of unfamiliar people – the intense pressure was evident in my expression.

This occurred since scientists were filming this quite daunting experience for a scientific study that is analyzing anxiety using heat-sensing technology.

Anxiety modifies the blood distribution in the facial area, and researchers have found that the drop in temperature of a subject's face can be used as a measure of stress levels and to track recuperation.

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

The Scientific Tension Assessment

The experimental stress test 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 about to experience.

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

Thus far, quite relaxing.

Then, the researcher who was overseeing the assessment brought in a group of unfamiliar people into the space. They each looked at me without speaking as the scientist explained that I now had three minutes to develop a five minute speech about my "ideal career".

As I felt the warmth build around my collar area, the researchers recorded my face changing colour through their infrared device. My facial temperature immediately decreased in heat – turning blue on the thermal image – as I thought about how to navigate this unplanned presentation.

Scientific Results

The investigators have performed this same stress test on numerous subjects. In every case, they noticed the facial region dip in temperature by a noticeable amount.

My nasal area cooled in warmth by two degrees, as my physiological mechanism redirected circulation from my nasal region and to my eyes and ears – a physiological adaptation to help me to see and detect for threats.

Most participants, similar to myself, recovered quickly; their noses warmed to baseline measurements within a short time.

Head scientist stated that being a reporter and broadcaster has probably made me "somewhat accustomed to being put in tense situations".

"You are used to the recording equipment and speaking to strangers, so you're likely somewhat resistant to social stressors," she explained.

"But even someone like you, accustomed to being tense circumstances, exhibits a biological blood flow shift, so which implies this 'nasal dip' is a reliable indicator of a altering tension condition."

Stress Management Applications

Tension is inevitable. But this revelation, the experts claim, could be used to assist in controlling negative degrees of anxiety.

"The length of time it takes an individual to bounce back from this cooling effect could be an reliable gauge of how well an individual controls their anxiety," said the lead researcher.

"Should they recover exceptionally gradually, could this indicate a warning sign of psychological issues? Is it something that we can address?"

Since this method is non-intrusive and records biological reactions, 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 tension measurement was, from my perspective, even worse than the first. I was asked to count sequentially decreasing from 2023 in increments of seventeen. A member of the group of expressionless people stopped me every time I committed an error and told me to start again.

I acknowledge, I am inexperienced in calculating mentally.

During the uncomfortable period attempting to compel my thinking to accomplish subtraction, my sole consideration was that I wanted to flee the progressively tense environment.

Throughout the study, only one of the 29 volunteers for the anxiety assessment did truly seek to depart. The remainder, like me, finished their assignments – probably enduring varying degrees of discomfort – and were given another calming session of ambient sound through headphones at the finish.

Primate Study Extensions

Maybe among the most remarkable features of the method is that, because thermal cameras record biological tension reactions that is natural to various monkey types, it can furthermore be utilized in animal primates.

The investigators are currently developing its use in refuges for primates, such as chimps and gorillas. They aim to determine how to lower tension and improve the wellbeing of animals that may have been removed from traumatic circumstances.

Researchers have previously discovered that presenting mature chimps video footage of infant chimps has a calming effect. When the researchers set up a display monitor adjacent to the protected apes' living area, they saw the noses of animals that watched the material warm up.

So, in terms of stress, watching baby animals engaging in activities is the inverse of a unexpected employment assessment or an on-the-spot subtraction task.

Potential Uses

Using thermal cameras in ape sanctuaries could turn out to be useful for assisting rehabilitated creatures to become comfortable to a unfamiliar collective and unknown territory.
