When I was asked to deliver an unprepared brief presentation and then calculate in reverse in increments of seventeen – before a panel of three strangers – the acute stress was written on my face.

The reason was that scientists were documenting this rather frightening scenario for a research project that is studying stress using heat-sensing technology.

Tension changes the blood flow in the facial area, and experts have determined that the drop in temperature of a subject's face can be used as a indicator of tension and to track recuperation.

Heat mapping, based on researcher findings behind the study could be a "transformative advancement" in stress research.

The Experimental Stress Test

The scientific tension assessment that I participated in is precisely structured and intentionally created to be an discomforting experience. I arrived at the research facility with minimal awareness what I was facing.

Initially, I was instructed to position myself, relax and hear white noise through a audio headset.

Up to this point, very peaceful.

Subsequently, the investigator who was running the test brought in a trio of unknown individuals into the space. They collectively gazed at me without speaking as the investigator stated that I now had 180 seconds to develop a five minute speech about my "dream job".

While experiencing the temperature increase around my neck, the researchers recorded my complexion altering through their thermal camera. My nasal area rapidly cooled in warmth – turning blue on the heat map – as I contemplated ways to navigate this unplanned presentation.

Research Findings

The investigators have performed this equivalent anxiety evaluation on numerous subjects. In all instances, they observed the nasal area dip in temperature by between three and six degrees.

My nose dropped in heat by two degrees, as my nervous system pushed blood flow away from my nasal region and to my visual and auditory organs – a physiological adaptation to help me to look and listen for threats.

The majority of subjects, similar to myself, recovered quickly; their noses warmed to normal readings within a short time.

Principal investigator explained that being a media professional has probably made me "relatively adapted to being subjected to tense situations".

"You're familiar with the camera and conversing with unknown individuals, so you're probably quite resilient to social stressors," the scientist clarified.

"However, even individuals such as yourself, experienced in handling anxiety-provoking scenarios, demonstrates a physiological circulation change, so which implies this 'nose temperature drop' is a consistent measure of a altering tension condition."

Stress Management Applications

Stress is part of life. But this finding, the experts claim, could be used to aid in regulating damaging amounts of tension.

"The period it takes a person to return to normal from this nasal dip could be an quantifiable indicator of how well a person manages their tension," explained the head scientist.

"Should they recover exceptionally gradually, might this suggest a risk marker of mental health concerns? Could this be a factor that we can tackle?"

Because this technique is without physical contact and measures a physical response, it could additionally prove valuable to track anxiety in infants or in those with communication challenges.

The Mental Arithmetic Challenge

The subsequent challenge in my anxiety evaluation was, personally, more challenging than the opening task. I was instructed to subtract backwards from 2023 in intervals of 17. Someone on the panel of three impassive strangers interrupted me whenever I calculated incorrectly and told me to begin anew.

I acknowledge, I am bad at mental arithmetic.

As I spent awkward duration attempting to compel my brain to perform arithmetic operations, the only thought was that I wanted to flee the growing uncomfortable space.

In the course of the investigation, merely one of the numerous subjects for the stress test did genuinely request to leave. The rest, similar to myself, finished their assignments – likely experiencing assorted amounts of discomfort – and were rewarded with a further peaceful interval of white noise through earphones at the conclusion.

Primate Study Extensions

Maybe among the most unexpected elements of the method is that, as heat-sensing technology record biological tension reactions that is natural to various monkey types, it can furthermore be utilized in other species.

The investigators are currently developing its application in refuges for primates, comprising various ape species. They aim to determine how to lower tension and enhance the welfare of primates that may have been rescued from distressing situations.

The team has already found that showing adult chimpanzees visual content of young primates has a soothing influence. When the scientists installed a video screen adjacent to the protected apes' living area, they observed the nasal areas of primates that viewed the material warm up.

Therefore, regarding anxiety, watching baby animals playing is the contrary to a surprise job interview or an impromptu mathematical challenge.

Potential Uses

Employing infrared imaging in ape sanctuaries could prove to be valuable in helping protected primates to adapt and acclimate to a different community and strange surroundings.
