Upon being told to present an off-the-cuff five-minute speech and then calculate in reverse in steps of 17 – before a panel of three strangers – the sudden tension was written on my face.

That is because researchers were documenting this rather frightening experience for a research project that is examining tension using thermal cameras.

Anxiety modifies the circulation in the facial area, and experts have determined that the drop in temperature of a subject's face can be used as a gauge of anxiety and to monitor recovery.

Heat mapping, based on researcher findings conducting the research could be a "revolutionary development" in anxiety studies.

The Scientific Tension Assessment

The scientific tension assessment that I participated in is meticulously designed and deliberately designed to be an unexpected challenge. I visited the research facility with minimal awareness what I was in for.

To begin, I was asked to sit, unwind and experience ambient sound through a set of headphones.

Up to this point, very peaceful.

Subsequently, the investigator who was running the test introduced a group of unfamiliar people into the room. They collectively gazed at me silently as the researcher informed that I now had three minutes to create a brief presentation about my "dream job".

While experiencing the heat rise around my neck, the scientists captured my complexion altering through their infrared device. My nasal area rapidly cooled in warmth – appearing cooler on the thermal image – as I considered how to bluster my way through this impromptu speech.

Research Findings

The investigators have conducted this identical tension assessment on 29 volunteers. In each, they saw their nose dip in temperature by between three and six degrees.

My facial temperature decreased in temperature by a small amount, as my biological response system pushed blood flow away from my nasal region and to my visual and auditory organs – a bodily response to assist me in see and detect for danger.

Most participants, like me, recovered quickly; their nasal areas heated 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 are used to the camera and conversing with unknown individuals, so you're likely quite resilient to interpersonal pressures," the scientist clarified.

"However, even individuals such as yourself, trained to be stressful situations, shows a biological blood flow shift, so this indicates this 'nasal dip' is a robust marker of a shifting anxiety level."

Stress Management Applications

Anxiety is natural. But this discovery, the scientists say, could be used to help manage negative degrees of anxiety.

"The length of time it takes someone to recover from this cooling effect could be an quantifiable indicator of how well a person manages their anxiety," said the lead researcher.

"When they return exceptionally gradually, could that be a potential indicator of psychological issues? Is it something that we can tackle?"

Because this technique is non-intrusive and records biological reactions, it could also be useful to track anxiety in infants or in individuals unable to express themselves.

The Mental Arithmetic Challenge

The subsequent challenge in my anxiety evaluation was, in my view, more difficult than the initial one. I was told to calculate backwards from 2023 in increments of seventeen. One of the observers of expressionless people stopped me each instance I committed an error and instructed me to start again.

I confess, I am poor with calculating mentally.

During the awkward duration attempting to compel my brain to perform subtraction, the only thought was that I wished to leave the progressively tense environment.

In the course of the investigation, merely one of the numerous subjects for the stress test did genuinely request to depart. The others, similar to myself, accomplished their challenges – presumably feeling varying degrees of humiliation – and were compensated by another calming session of background static through earphones at the finish.

Non-Human Applications

Possibly included in the most surprising aspects of the approach is that, because thermal cameras monitor physiological anxiety indicators that is natural to numerous ape species, it can furthermore be utilized in other species.

The scientists are presently creating its application in habitats for large monkeys, comprising various ape species. They seek to establish how to lower tension and enhance the welfare of creatures that may have been saved from traumatic circumstances.

Scientists have earlier determined that displaying to grown apes recorded material of baby chimpanzees has a relaxing impact. When the investigators placed a visual device near the protected apes' living area, they observed the nasal areas of creatures that observed the footage increase in temperature.

So, in terms of stress, viewing infant primates playing is the opposite of a surprise job interview or an on-the-spot subtraction task.

Coming Implementations

Implementing heat-sensing technology in monkey habitats could turn out to be useful for assisting protected primates to adapt and acclimate to a different community and strange surroundings.
