When I was asked to deliver an unprepared short talk and then count backwards in steps of 17 – all in front of a panel of three strangers – the acute stress was written on my face.

This occurred since researchers were documenting this quite daunting experience for a research project that is examining tension using infrared imaging.

Tension changes the blood flow in the face, and experts have determined that the cooling effect of a person's nose can be used as a measure of stress levels and to monitor recovery.

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

The Scientific Tension Assessment

The research anxiety evaluation that I participated in is carefully controlled and deliberately designed to be an unpleasant surprise. I came to the research facility with little knowledge what I was facing.

Initially, I was asked to sit, calm down and experience white noise through a pair of earphones.

Up to this point, very peaceful.

Afterward, the investigator who was conducting the experiment introduced a panel of three strangers into the area. They all stared at me quietly as the scientist explained that I now had three minutes to develop a short talk about my "ideal career".

As I felt the warmth build around my throat, the scientists captured my skin tone shifting through their infrared device. My facial temperature immediately decreased in heat – turning blue on the thermal image – as I thought about how to navigate this unplanned presentation.

Scientific Results

The scientists have carried out this same stress test on numerous subjects. In every case, they saw their nose decrease in warmth by between three and six degrees.

My nose dropped in temperature by two degrees, as my nervous system pushed blood flow away from my nasal region and to my sensory systems – a physiological adaptation to enable me to see and detect for danger.

Most participants, comparable to my experience, bounced back rapidly; their noses warmed to pre-stressed levels within a short time.

Head scientist stated that being a journalist and presenter has probably made me "relatively adapted to being put in stressful positions".

"You're accustomed to the camera and speaking to strangers, so you're likely relatively robust to public speaking anxieties," the scientist clarified.

"Nevertheless, even people with your background, accustomed to being anxiety-provoking scenarios, shows a physiological circulation change, so this indicates this 'nasal dip' is a reliable indicator of a altering tension condition."

Tension Regulation Possibilities

Stress is part of life. But this revelation, the researchers state, could be used to aid in regulating negative degrees of stress.

"The duration it takes someone to recover from this cooling effect could be an reliable gauge of how effectively a person manages their tension," explained the head scientist.

"If they bounce back remarkably delayed, could that be a warning sign of anxiety or depression? Could this be a factor that we can do anything about?"

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

The Mathematical Stress Test

The following evaluation in my anxiety evaluation was, from my perspective, more challenging than the opening task. I was asked to count in reverse starting from 2023 in intervals of 17. A member of the group of unresponsive individuals stopped me every time I calculated incorrectly and told me to recommence.

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

As I spent uncomfortable period trying to force my brain to perform arithmetic operations, my sole consideration was that I wished to leave the growing uncomfortable space.

During the research, only one of the 29 volunteers for the anxiety assessment did truly seek to depart. The others, similar to myself, completed their tasks – likely experiencing assorted amounts of discomfort – and were rewarded with an additional relaxation period of ambient sound through earphones at the conclusion.

Primate Study Extensions

Possibly included in the most surprising aspects of the approach is that, since infrared imaging monitor physiological anxiety indicators that is natural to many primates, it can also be used in non-human apes.

The scientists are presently creating its use in sanctuaries for great apes, including chimpanzees and gorillas. They want to work out how to reduce stress and enhance the welfare of primates that may have been removed from traumatic circumstances.

Scientists have earlier determined that presenting mature chimps video footage of young primates has a soothing influence. When the researchers set up a display monitor adjacent to the rescued chimps' enclosure, they saw the noses of primates that viewed the footage warm up.

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

Potential Uses

Using thermal cameras in monkey habitats could demonstrate itself as valuable in helping rescued animals to become comfortable to a new social group and unknown territory.
