After being requested to deliver an unprepared brief presentation and then count backwards in increments of seventeen – while facing a panel of three strangers – the intense pressure was visible in my features.

The reason was that researchers were recording this somewhat terrifying experience for a research project that is studying stress using heat-sensing technology.

Anxiety modifies the blood flow in the facial area, and experts have determined that the cooling effect of a subject's face can be used as a measure of stress levels and to monitor recovery.

Thermal imaging, according to the psychologists conducting the research could be a "revolutionary development" in anxiety studies.

The Experimental Stress Test

The scientific tension assessment that I participated in is meticulously designed and intentionally created to be an unexpected challenge. I arrived at the university with little knowledge what I was facing.

Initially, I was told to settle, calm down and listen to white noise through a audio headset.

Up to this point, very peaceful.

Then, the investigator who was conducting the experiment introduced a group of unfamiliar people into the room. They each looked at me silently as the investigator stated that I now had 180 seconds to create a five minute speech about my "ideal career".

As I felt the temperature increase around my neck, the experts documented my face changing colour through their heat-sensing equipment. My facial temperature immediately decreased in heat – showing colder on the infrared display – as I considered how to bluster my way through this impromptu speech.

Scientific Results

The researchers have performed this identical tension assessment on numerous subjects. In every case, they saw their nose cool down by several degrees.

My nose dropped in heat by a couple of degrees, as my physiological mechanism redirected circulation from my nasal region and to my eyes and ears – a physical reaction to assist me in observe and hear for hazards.

The majority of subjects, similar to myself, recovered quickly; their noses warmed to pre-stressed levels within a few minutes.

Head scientist explained that being a media professional has probably made me "quite habituated to being subjected to tense situations".

"You are used to the camera and speaking to unknown individuals, so you're probably quite resilient to social stressors," the researcher noted.

"However, even individuals such as yourself, trained to be anxiety-provoking scenarios, demonstrates a biological blood flow shift, so that suggests this 'facial cooling' is a consistent measure of a shifting anxiety level."

Anxiety Control Uses

Stress is part of life. But this finding, the experts claim, could be used to assist in controlling negative degrees of stress.

"The duration it takes an individual to bounce back from this cooling effect could be an reliable gauge of how effectively somebody regulates their stress," noted the principal investigator.

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

As this approach is non-intrusive and monitors physiological changes, it could also be useful to monitor stress in babies or in people who can't communicate.

The Calculation Anxiety Assessment

The second task in my tension measurement was, from my perspective, more challenging than the initial one. I was told to calculate in reverse starting from 2023 in intervals of 17. A member of the group of unresponsive individuals interrupted me each instance I calculated incorrectly and instructed me to recommence.

I admit, I am bad at doing math in my head.

As I spent uncomfortable period attempting to compel my mind to execute subtraction, all I could think was that I wished to leave the growing uncomfortable space.

Throughout the study, just a single of the 29 volunteers for the anxiety assessment did genuinely request to exit. The others, comparable to my experience, finished their assignments – probably enduring varying degrees of embarrassment – and were compensated by an additional relaxation period of white noise through earphones at the end.

Non-Human Applications

Maybe among the most remarkable features of the method is that, as heat-sensing technology record biological tension reactions that is inherent within various monkey types, it can furthermore be utilized in non-human apes.

The researchers are currently developing its use in sanctuaries for great apes, including chimpanzees and gorillas. They aim to determine how to lower tension and enhance the welfare of animals that may have been removed from harmful environments.

Scientists have earlier determined that displaying to grown apes recorded material of baby chimpanzees has a relaxing impact. When the scientists installed a video screen close to the protected apes' living area, they noticed the facial regions of animals that watched the footage warm up.

Therefore, regarding anxiety, watching baby animals engaging in activities is the contrary to a surprise job interview or an spontaneous calculation test.

Potential Uses

Using thermal cameras in monkey habitats could prove to be useful for assisting rescued animals to adapt and acclimate to a different community and unknown territory.
