When I was asked to give an impromptu brief presentation and then count backwards in intervals of 17 – while facing a trio of unknown individuals – the acute stress was visible in my features.

This occurred since psychologists were documenting this rather frightening experience for a scientific study that is studying stress using heat-sensing technology.

Stress alters the circulation in the face, and scientists have discovered that the cooling effect 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 "revolutionary development" in tension analysis.

The Scientific Tension Assessment

The experimental stress test that I underwent is precisely structured and purposely arranged to be an unexpected challenge. I arrived at the research facility with little knowledge what I was in for.

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

Thus far, quite relaxing.

Then, the researcher who was running the test invited a trio of unknown individuals into the space. They all stared at me without speaking as the researcher informed that I now had 180 seconds to prepare a short talk about my "ideal career".

When noticing the temperature increase around my collar area, the researchers recorded my skin tone shifting through their infrared device. My nasal area rapidly cooled in heat – showing colder on the infrared display – as I considered how to bluster my way through this impromptu speech.

Study Outcomes

The researchers have conducted this identical tension assessment on multiple participants. In each, they observed the nasal area dip in temperature by between three and six degrees.

My nose dropped in temperature by a couple of degrees, as my biological response system pushed blood flow away from my nose and to my eyes and ears – a physiological adaptation to enable me to observe and hear for hazards.

The majority of subjects, like me, recovered quickly; their noses warmed to pre-stressed levels within a short time.

Principal investigator noted that being a media professional has probably made me "relatively adapted to being placed in anxiety-provoking circumstances".

"You're familiar with the recording equipment and speaking to unfamiliar people, so you're probably quite resilient to social stressors," she explained.

"Nevertheless, even people with your background, experienced in handling stressful situations, shows a bodily response alteration, so this indicates this 'facial cooling' is a consistent measure of a changing stress state."

Anxiety Control Uses

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

"The length of time it takes a person to return to normal from this cooling effect could be an reliable gauge of how efficiently an individual controls their tension," explained the head scientist.

"When they return exceptionally gradually, could this indicate a risk marker of anxiety or depression? Is it something that we can address?"

Because this technique is non-invasive and measures a physical response, it could also be useful to track anxiety in newborns or in those with communication challenges.

The Mathematical Stress Test

The subsequent challenge in my anxiety evaluation was, in my view, more challenging than the opening task. I was instructed to subtract backwards from 2023 in intervals of 17. Someone on the panel of unresponsive individuals halted my progress every time I made a mistake and asked me to begin anew.

I confess, I am poor with doing math in my head.

While I used embarrassing length of time attempting to compel my mind to execute arithmetic operations, the only thought was that I desired to escape the increasingly stuffy room.

Throughout the study, just a single of the 29 volunteers for the stress test did actually ask to exit. The rest, like me, completed their tasks – likely experiencing different levels of embarrassment – and were given a further peaceful interval of ambient sound through headphones at the finish.

Non-Human Applications

Possibly included in the most unexpected elements of the method is that, as heat-sensing technology record biological tension reactions that is inherent within many primates, it can also be used in other species.

The scientists are actively working on its use in sanctuaries for great apes, such as chimps and gorillas. They seek to establish how to reduce stress and enhance the welfare of animals that may have been rescued from harmful environments.

Researchers have previously discovered that displaying to grown apes visual content of infant chimps has a soothing influence. When the investigators placed a video screen adjacent to the rehabilitated primates' habitat, they noticed the facial regions of creatures that observed the footage heat up.

Therefore, regarding anxiety, viewing infant primates playing is the contrary to a unexpected employment assessment or an on-the-spot subtraction task.

Potential Uses

Implementing heat-sensing technology in ape sanctuaries could prove to be useful for assisting rehabilitated creatures to adjust and settle in to a unfamiliar collective and strange surroundings.
