Doing Math in Your Head Really Stresses Me Out and Studies Demonstrate This

After being requested to present an off-the-cuff brief presentation and then calculate in reverse in intervals of 17 – all in front of a group of unfamiliar people – the sudden tension was written on my face.

This occurred since researchers were recording this somewhat terrifying situation for a scientific study that is studying stress using infrared imaging.

Tension changes the blood flow in the face, and scientists have discovered that the drop in temperature of a person's nose can be used as a gauge of anxiety and to monitor recovery.

Infrared technology, according to the psychologists conducting the research could be a "transformative advancement" in tension analysis.

The Experimental Stress Test

The experimental stress test that I participated in is carefully controlled and deliberately designed to be an unexpected challenge. I visited the research facility with no idea what I was facing.

First, I was instructed to position myself, unwind and experience white noise through a audio headset.

So far, so calming.

Then, the researcher who was running the test brought in a trio of unknown individuals into the room. They all stared at me without speaking as the investigator stated that I now had three minutes to prepare a brief presentation about my "ideal career".

When noticing the heat rise around my collar area, the researchers recorded my complexion altering through their heat-sensing equipment. My nose quickly dropped in temperature – showing colder on the infrared display – as I thought about how to bluster my way through this impromptu speech.

Research Findings

The scientists have carried out this identical tension assessment on numerous subjects. In every case, they noticed the facial region decrease in warmth by several degrees.

My facial temperature decreased in temperature by two degrees, as my biological response system pushed blood flow away from my face and to my visual and auditory organs – a bodily response to enable me to see and detect for danger.

The majority of subjects, like me, bounced back rapidly; their nasal areas heated to baseline measurements within a few minutes.

Principal investigator noted that being a journalist and presenter has probably made me "somewhat accustomed to being placed in stressful positions".

"You're familiar with the filming device and speaking to unfamiliar people, so you're likely somewhat resistant to public speaking anxieties," she explained.

"But even someone like you, trained to be tense circumstances, demonstrates a biological blood flow shift, so that suggests this 'nasal dip' is a reliable indicator of a changing stress state."

Tension Regulation Possibilities

Anxiety is natural. But this discovery, the experts claim, could be used to aid in regulating damaging amounts of tension.

"The duration it takes an individual to bounce back from this cooling effect could be an reliable gauge of how efficiently somebody regulates their tension," explained the head scientist.

"If they bounce back unusually slowly, could that be a potential indicator of mental health concerns? Is it something that we can do anything about?"

As this approach is without physical contact and measures a physical response, it could also be useful to track anxiety in infants or in people who can't communicate.

The Mathematical Stress Test

The second task in my tension measurement was, personally, more challenging than the first. I was told to calculate backwards from 2023 in intervals of 17. One of the observers of unresponsive individuals stopped me every time I calculated incorrectly and asked me to recommence.

I acknowledge, I am bad at calculating mentally.

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

Throughout the study, just a single of the multiple participants for the anxiety assessment did genuinely request to exit. The rest, similar to myself, finished their assignments – probably enduring varying degrees of embarrassment – and were rewarded with another calming session of white noise through audio devices at the finish.

Non-Human Applications

Maybe among the most unexpected elements of the approach is that, because thermal cameras monitor physiological anxiety indicators that is natural to numerous ape species, it can additionally be applied in other species.

The investigators are actively working on its application in sanctuaries for great apes, such as chimps and gorillas. They aim to determine how to reduce stress and boost the health of creatures that may have been removed from harmful environments.

The team has already found that displaying to grown apes visual content of baby chimpanzees has a calming effect. When the scientists installed a visual device close to the rescued chimps' enclosure, they noticed the facial regions of animals that watched the content warm up.

Therefore, regarding anxiety, viewing infant primates playing is the opposite of a unexpected employment assessment or an impromptu mathematical challenge.

Potential Uses

Employing infrared imaging in primate refuges could turn out to be beneficial in supporting rehabilitated creatures to adapt and acclimate to a different community and strange surroundings.
