After being requested to present an off-the-cuff brief presentation and then subtract sequentially in intervals of 17 – all in front of a panel of three strangers – the intense pressure was visible in my features.

The reason was that researchers were recording this somewhat terrifying scenario for a research project that is examining tension using infrared imaging.

Anxiety modifies the blood distribution in the countenance, and scientists have discovered that the cooling effect of a subject's face can be used as a indicator of tension and to monitor recovery.

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

The Scientific Tension Assessment

The experimental stress test that I subjected myself to is carefully controlled and purposely arranged to be an unexpected challenge. I visited the research facility with no idea what I was facing.

First, I was instructed to position myself, relax and experience background static through a audio headset.

Thus far, quite relaxing.

Subsequently, the investigator who was conducting the experiment invited a group of unfamiliar people into the room. They each looked at me quietly as the scientist explained that I now had three minutes to prepare a short talk about my "dream job".

When noticing the warmth build around my throat, the scientists captured my face changing colour through their infrared device. My nose quickly dropped in warmth – turning blue on the heat map – as I considered how to manage this spontaneous talk.

Research Findings

The scientists have conducted this same stress test on numerous subjects. In all instances, they saw their nose cool down by a noticeable amount.

My nasal area cooled in heat by two degrees, as my nervous system redirected circulation from my nasal region and to my visual and auditory organs – a bodily response to assist me in look and listen for danger.

Nearly all volunteers, comparable to my experience, recovered quickly; their noses warmed to normal readings within a short time.

Principal investigator explained that being a journalist and presenter has probably made me "relatively adapted to being put in stressful positions".

"You are used to the recording equipment and conversing with unknown individuals, so it's probable you're relatively robust to interpersonal pressures," the scientist clarified.

"Nevertheless, even people with your background, experienced in handling stressful situations, shows a bodily response alteration, so that suggests this 'nose temperature drop' is a reliable indicator of a altering tension condition."

Tension Regulation Possibilities

Tension is inevitable. But this revelation, the experts claim, could be used to aid in regulating harmful levels of anxiety.

"The duration it takes an individual to bounce back from this nasal dip could be an objective measure of how efficiently somebody regulates their tension," explained the principal investigator.

"If they bounce back remarkably delayed, might this suggest a warning sign of psychological issues? Could this be a factor that we can do anything about?"

Since this method is without physical contact and measures a physical response, it could furthermore be beneficial to track anxiety in newborns or in those with communication challenges.

The Mathematical Stress Test

The subsequent challenge in my anxiety evaluation was, from my perspective, more challenging than the opening task. I was told to calculate sequentially decreasing from 2023 in steps of 17. One of the observers of unresponsive individuals halted my progress whenever I committed an error and asked me to start again.

I admit, I am poor with mental arithmetic.

During the awkward duration trying to force my brain to perform arithmetic operations, the only thought was that I desired to escape the growing uncomfortable space.

Throughout the study, only one of the multiple participants for the stress test did genuinely request to exit. The rest, similar to myself, completed their tasks – probably enduring assorted amounts of embarrassment – and were given another calming session of ambient sound through audio devices at the finish.

Non-Human Applications

Possibly included in the most unexpected elements of the method is that, as heat-sensing technology measure a physical stress response that is innate in many primates, it can also be used in other species.

The scientists are currently developing its use in refuges for primates, such as chimps and gorillas. They seek to establish how to lower tension and enhance the welfare of creatures 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 scientists installed a video screen adjacent to the protected apes' living area, they observed the nasal areas of primates that viewed the material heat up.

Therefore, regarding anxiety, viewing infant primates interacting is the inverse of a surprise job interview or an impromptu mathematical challenge.

Coming Implementations

Using thermal cameras in ape sanctuaries could turn out to be useful for assisting rescued animals to become comfortable to a different community and unfamiliar environment.
