After being requested to give an impromptu short talk and then calculate in reverse in intervals of 17 – all in front of a trio of unknown individuals – the intense pressure was evident in my expression.

The reason was that researchers were documenting this somewhat terrifying situation for a scientific study that is analyzing anxiety using infrared imaging.

Stress alters the blood flow in the face, and experts have determined that the cooling effect of a individual's nasal area can be used as a gauge of anxiety and to monitor recovery.

Thermal imaging, based on researcher findings conducting the research could be a "game changer" in stress research.

The Scientific Tension Assessment

The experimental stress test that I participated in is carefully controlled and intentionally created to be an unexpected challenge. I came to the university with little knowledge what I was in for.

Initially, I was asked to sit, calm down and hear ambient sound through a audio headset.

So far, so calming.

Subsequently, the investigator who was conducting the experiment introduced a trio of unknown individuals into the area. They each looked at me silently as the scientist explained that I now had three minutes to prepare a five minute speech about my "perfect occupation".

When noticing the temperature increase around my neck, the experts documented my skin tone shifting through their heat-sensing equipment. My nose quickly dropped in temperature – appearing cooler on the thermal image – as I contemplated ways to navigate this impromptu speech.

Study Outcomes

The researchers have conducted this equivalent anxiety evaluation on multiple participants. In all instances, they observed the nasal area cool down by a noticeable amount.

My nose dropped in warmth by a small amount, as my biological response system shifted blood distribution from my face and to my eyes and ears – a physiological adaptation to assist me in see and detect for threats.

Nearly all volunteers, like me, recovered quickly; their noses warmed to pre-stressed levels within a brief period.

Lead researcher stated that being a media professional has probably made me "somewhat accustomed to being put in stressful positions".

"You are used to the recording equipment and talking with strangers, so it's probable you're somewhat resistant to social stressors," the researcher noted.

"However, even individuals such as yourself, accustomed to being stressful situations, exhibits a biological blood flow shift, so which implies this 'nose temperature drop' is a consistent measure of a changing stress state."

Stress Management Applications

Stress is part of life. But this discovery, the researchers state, could be used to help manage negative degrees of tension.

"The duration it takes a person to return to normal from this temperature drop could be an objective measure of how well somebody regulates their tension," noted the principal investigator.

"When they return unusually slowly, could this indicate a warning sign of mental health concerns? Is it something that we can address?"

Since this method is without physical contact and records biological reactions, it could furthermore be beneficial to observe tension in infants or in those with communication challenges.

The Mental Arithmetic Challenge

The subsequent challenge in my stress assessment was, personally, more difficult than the first. I was asked to count backwards from 2023 in increments of seventeen. One of the observers of expressionless people stopped me whenever I made a mistake and told me to begin anew.

I confess, I am poor with calculating mentally.

While I used awkward duration trying to force my thinking to accomplish mathematical calculations, all I could think was that I wanted to flee the growing uncomfortable space.

Throughout the study, merely one of the multiple participants for the tension evaluation did truly seek to depart. The remainder, similar to myself, finished their assignments – probably enduring varying degrees of discomfort – and were rewarded with a further peaceful interval of white noise through audio devices at the conclusion.

Animal Research Applications

Possibly included in the most unexpected elements of the method is that, because thermal cameras measure a physical stress response that is innate in various monkey types, it can also be used in animal primates.

The scientists are currently developing its application in refuges for primates, such as chimps and gorillas. They aim to determine how to reduce stress and boost the health of primates that may have been removed from traumatic circumstances.

The team has already found that displaying to grown apes recorded material of young primates has a soothing influence. When the researchers set up a display monitor close to the protected apes' living area, they observed the nasal areas of primates that viewed the footage heat up.

So, in terms of stress, observing young creatures interacting is the opposite of a surprise job interview or an impromptu mathematical challenge.

Potential Uses

Employing infrared imaging in primate refuges could demonstrate itself as useful for assisting protected primates to adjust and settle in to a different community and unfamiliar environment.
