Doing Math in Your Head Really Stresses Me Out and Science Has Proved It

After being requested to present an off-the-cuff brief presentation and then calculate in reverse in steps of 17 – while facing a group of unfamiliar people – the sudden tension was visible in my features.

The reason was that scientists were recording this quite daunting scenario for a scientific study that is studying stress using thermal cameras.

Stress alters the blood distribution in the countenance, and experts have determined that the thermal decrease of a individual's nasal area can be used as a gauge of anxiety and to track recuperation.

Thermal imaging, based on researcher findings leading the investigation could be a "transformative advancement" in anxiety studies.

The Experimental Stress Test

The research anxiety evaluation that I underwent is precisely structured and intentionally created to be an unexpected challenge. I visited the research facility with little knowledge what I was facing.

Initially, I was asked to sit, unwind and experience ambient sound through a pair of earphones.

Up to this point, very peaceful.

Afterward, the scientist who was overseeing the assessment introduced a panel of three strangers into the room. They collectively gazed at me quietly as the investigator stated that I now had three minutes to create a brief presentation about my "perfect occupation".

As I felt the heat rise around my neck, the researchers recorded my complexion altering through their infrared device. My nose quickly dropped in heat – appearing cooler on the heat map – as I thought about how to manage this unplanned presentation.

Research Findings

The investigators have carried out this same stress test on multiple participants. In each, they observed the nasal area decrease in warmth by several degrees.

My nose dropped in temperature by a couple of degrees, as my biological response system redirected circulation from my nose and to my sensory systems – a bodily response to assist me in observe and hear for danger.

The majority of subjects, comparable to my experience, returned to normal swiftly; their nasal areas heated to baseline measurements within a brief period.

Lead researcher explained that being a reporter and broadcaster has probably made me "relatively adapted to being placed in tense situations".

"You are used to the filming device and conversing with strangers, so you're likely quite resilient to social stressors," she explained.

"But even someone like you, trained to be tense circumstances, shows a biological blood flow shift, so that suggests this 'nose temperature drop' is a reliable indicator of a altering tension condition."

Anxiety Control Uses

Tension is inevitable. But this discovery, the researchers state, could be used to help manage damaging amounts of anxiety.

"The length of time it takes a person to return to normal from this nasal dip could be an reliable gauge of how efficiently a person manages their stress," noted the principal investigator.

"Should they recover exceptionally gradually, could this indicate a warning sign of anxiety or depression? Is this an aspect that we can do anything about?"

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 Mental Arithmetic Challenge

The second task in my anxiety evaluation was, personally, more difficult than the first. I was instructed to subtract in reverse starting from 2023 in steps of 17. Someone on the panel of expressionless people interrupted me every time I made a mistake and instructed me to begin anew.

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

As I spent uncomfortable period striving to push my mind to execute mathematical calculations, the only thought was that I wanted to flee the increasingly stuffy room.

In the course of the investigation, merely one of the multiple participants for the anxiety assessment did genuinely request to depart. The rest, comparable to my experience, finished their assignments – probably enduring assorted amounts of discomfort – and were compensated by another calming session of ambient sound through audio devices at the end.

Animal Research Applications

Perhaps one of the most unexpected elements of the method is that, because thermal cameras record biological tension reactions that is inherent within numerous ape species, it can furthermore be utilized in animal primates.

The scientists are currently developing its implementation within habitats for large monkeys, including chimpanzees and gorillas. They want to work out how to decrease anxiety and boost the health of primates that may have been rescued from distressing situations.

Scientists have earlier determined that displaying to grown apes visual content of baby chimpanzees has a calming effect. When the scientists installed a visual device adjacent to the rehabilitated primates' habitat, they noticed the facial regions of primates that viewed the content warm up.

So, in terms of stress, watching baby animals interacting is the opposite of a spontaneous career evaluation or an spontaneous calculation test.

Coming Implementations

Using thermal cameras in primate refuges could prove to be beneficial in supporting rescued animals to adjust and settle in to a unfamiliar collective and strange surroundings.
