When I was asked to present an off-the-cuff brief presentation and then calculate in reverse in intervals of 17 – all in front of a panel of three strangers – the acute stress was evident in my expression.

This occurred since scientists were recording this somewhat terrifying scenario for a investigation that is examining tension using infrared imaging.

Anxiety modifies the blood flow in the face, 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, as stated by the scientists leading the investigation could be a "game changer" in anxiety studies.

The Scientific Tension Assessment

The research anxiety evaluation that I subjected myself to is carefully controlled and deliberately designed to be an discomforting experience. I arrived at the research facility with little knowledge what I was about to experience.

To begin, I was asked to sit, relax and listen to white noise through a pair of earphones.

Thus far, quite relaxing.

Then, the scientist who was running the test brought in a group of unfamiliar people into the room. They each looked at me silently as the scientist explained that I now had 180 seconds to develop a short talk about my "ideal career".

As I felt the temperature increase around my throat, the researchers recorded my face changing colour through their heat-sensing equipment. My nose quickly dropped in heat – turning blue on the heat map – as I contemplated ways to manage this spontaneous talk.

Scientific Results

The researchers have conducted this same stress test on 29 volunteers. In every case, they noticed the facial region dip in temperature by several degrees.

My facial temperature decreased in warmth by a small amount, as my physiological mechanism redirected circulation from my nasal region and to my visual and auditory organs – a physiological adaptation to help me to see and detect for threats.

Nearly all volunteers, like me, bounced back rapidly; their nasal areas heated to normal readings within a short time.

Principal investigator stated that being a journalist and presenter has probably made me "somewhat accustomed to being subjected to tense situations".

"You're accustomed to the camera and speaking to unknown individuals, so it's probable you're somewhat resistant to public speaking anxieties," the researcher noted.

"But even someone like you, accustomed to being stressful situations, exhibits a bodily response alteration, so which implies this 'nasal dip' is a consistent measure of a shifting anxiety level."

Stress Management Applications

Stress is part of life. But this finding, the researchers state, could be used to aid in regulating harmful levels of stress.

"The period it takes someone to recover from this cooling effect could be an reliable gauge of how well a person manages their stress," explained the head scientist.

"If they bounce back exceptionally gradually, could that be a risk marker of psychological issues? Is this an aspect that we can address?"

As this approach is without physical contact and records biological reactions, it could furthermore be beneficial to track anxiety in babies or in people who can't communicate.

The Calculation Anxiety Assessment

The following evaluation in my anxiety evaluation was, from my perspective, more difficult than the initial one. I was told to calculate sequentially decreasing from 2023 in intervals of 17. One of the observers of unresponsive individuals interrupted me whenever I calculated incorrectly and told me to start again.

I acknowledge, I am inexperienced in mental arithmetic.

While I used embarrassing length of time striving to push my brain to perform arithmetic operations, all I could think was that I wanted to flee the increasingly stuffy room.

During the research, merely one of the 29 volunteers for the anxiety assessment did actually ask to exit. The others, like me, accomplished their challenges – likely experiencing different levels of humiliation – and were compensated by a further peaceful interval of ambient sound through headphones at the finish.

Primate Study Extensions

Perhaps one of the most remarkable features of the method is that, because thermal cameras record biological tension reactions that is innate in numerous ape species, it can additionally be applied in other species.

The researchers are presently creating its implementation within refuges for primates, including chimpanzees and gorillas. They want to work out how to lower tension and enhance the welfare of primates that may have been removed from distressing situations.

The team has already found that showing adult chimpanzees visual content of infant chimps has a calming effect. When the scientists installed a visual device close to the protected apes' living area, they observed the nasal areas of creatures that observed the material warm up.

Therefore, regarding anxiety, viewing infant primates playing is the contrary to a surprise job interview or an impromptu mathematical challenge.

Future Applications

Implementing heat-sensing technology in primate refuges could demonstrate itself as valuable in helping rescued animals to become comfortable to a different community and strange surroundings.
