Performing Calculations Mentally Truly Stresses Me Out and Science Has Proved It

After being requested to present an off-the-cuff short talk and then count backwards in steps of 17 – all in front of a group of unfamiliar people – the acute stress was written on my face.

The reason was that psychologists were recording this rather frightening scenario for a investigation that is examining tension using infrared imaging.

Stress alters the circulation in the facial area, and scientists have discovered that the thermal decrease of a subject's face can be used as a measure of stress levels and to observe restoration.

Thermal imaging, as stated by the scientists leading the investigation could be a "transformative advancement" in tension analysis.

The Experimental Stress Test

The experimental stress test that I underwent is meticulously designed and deliberately designed to be an discomforting experience. I arrived at the research facility with no idea what I was in for.

To begin, I was instructed to position myself, calm down and hear white noise through a set of headphones.

Up to this point, very peaceful.

Subsequently, the investigator who was running the test introduced a panel of three strangers into the area. They each looked at me quietly as the investigator stated that I now had a brief period to prepare a five minute speech about my "dream job".

While experiencing the heat rise around my collar area, the experts documented my face changing colour through their heat-sensing equipment. My nose quickly dropped in temperature – turning blue on the infrared display – as I contemplated ways to navigate this impromptu speech.

Scientific Results

The investigators have performed this same stress test on numerous subjects. In each, they saw their nose dip in temperature by several degrees.

My nasal area cooled in heat by a small amount, as my physiological mechanism shifted blood distribution from my nose and to my eyes and ears – a physical reaction to enable me to see and detect for hazards.

Nearly all volunteers, like me, recovered quickly; their nasal areas heated to normal readings within a few minutes.

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

"You are used to the recording equipment and speaking to unfamiliar people, so you're probably somewhat resistant to public speaking anxieties," 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 consistent measure of a shifting anxiety level."

Tension Regulation Possibilities

Stress is part of life. But this finding, the experts claim, could be used to help manage harmful levels of tension.

"The length of time it takes someone to recover from this cooling effect could be an reliable gauge of how efficiently an individual controls their stress," noted the principal investigator.

"Should they recover unusually slowly, could this indicate a warning sign of mental health concerns? Could this be a factor that we can address?"

Since this method is non-invasive and measures a physical response, it could also be useful to monitor stress in infants or in those with communication challenges.

The Mathematical Stress Test

The subsequent challenge in my tension measurement was, from my perspective, more difficult than the first. I was asked to count in reverse starting from 2023 in increments of seventeen. One of the observers of three impassive strangers halted my progress every time I calculated incorrectly and instructed me to recommence.

I admit, I am bad at mental arithmetic.

During the embarrassing length of time attempting to compel my mind to execute subtraction, the only thought was that I wished to leave the increasingly stuffy room.

In the course of the investigation, only one of the multiple participants for the tension evaluation did actually ask to exit. The remainder, like me, accomplished their challenges – probably enduring assorted amounts of discomfort – and were given another calming session of background static through headphones at the finish.

Non-Human Applications

Possibly included in the most remarkable features of the approach is that, since infrared imaging measure a physical stress response that is natural to many primates, it can additionally be applied in animal primates.

The investigators are currently developing its use in sanctuaries for great apes, comprising various ape species. They seek to establish how to decrease anxiety and improve the wellbeing of creatures that may have been removed from traumatic circumstances.

Researchers have previously discovered that displaying to grown apes visual content of baby chimpanzees has a calming effect. When the researchers set up a visual device close to the rehabilitated primates' habitat, they saw the noses of creatures that observed the content increase in temperature.

So, in terms of stress, observing young creatures engaging in activities is the opposite of a surprise job interview or an on-the-spot subtraction task.

Potential Uses

Employing infrared imaging in monkey habitats could turn out to be useful for assisting rescued animals to adapt and acclimate to a unfamiliar collective and strange surroundings.
