When I was asked to give an impromptu five-minute speech and then calculate in reverse in steps of 17 – before a group of unfamiliar people – the sudden tension was evident in my expression.

This occurred since researchers were filming this quite daunting situation for a research project that is studying stress using infrared imaging.

Anxiety modifies the circulation in the facial area, and experts have determined that the drop in temperature of a person's nose can be used as a measure of stress levels and to monitor recovery.

Infrared technology, as stated by the scientists leading the investigation could be a "transformative advancement" in anxiety studies.

The Scientific Tension Assessment

The experimental stress test that I participated in is carefully controlled and purposely arranged to be an unpleasant surprise. I visited the research facility with minimal awareness what I was in for.

First, I was asked to sit, relax and hear ambient sound through a audio headset.

Up to this point, very peaceful.

Then, the researcher who was overseeing the assessment introduced a trio of unknown individuals into the area. They collectively gazed at me without speaking as the researcher informed that I now had 180 seconds to develop a brief presentation about my "dream job".

When noticing the warmth build around my collar area, the scientists captured my skin tone shifting through their heat-sensing equipment. My nasal area rapidly cooled in warmth – showing colder on the thermal image – as I thought about how to bluster my way through this spontaneous talk.

Study Outcomes

The investigators have carried out this identical tension assessment on numerous subjects. In all instances, they observed the nasal area dip in temperature by between three and six degrees.

My nose dropped in heat by a couple of degrees, as my nervous system redirected circulation from my nasal region and to my sensory systems – a physical reaction to assist me in observe and hear for threats.

Nearly all volunteers, comparable to my experience, recovered quickly; their noses warmed to pre-stressed levels within a short time.

Lead researcher noted that being a media professional has probably made me "relatively adapted to being put in tense situations".

"You're accustomed to the camera and speaking to strangers, so it's probable you're quite resilient to social stressors," she explained.

"However, even individuals such as yourself, accustomed to being stressful situations, demonstrates a biological blood flow shift, so which implies this 'nose temperature drop' is a consistent measure of a changing stress state."

Tension Regulation Possibilities

Tension is inevitable. But this discovery, the experts claim, could be used to help manage harmful levels of stress.

"The duration it takes a person to return to normal from this cooling effect could be an objective measure of how well somebody regulates their anxiety," noted the head scientist.

"If they bounce back unusually slowly, could this indicate a warning sign of psychological issues? Is it something that we can do anything about?"

As this approach is non-invasive and records biological reactions, it could furthermore be beneficial to track anxiety in babies or in people who can't communicate.

The Mathematical Stress Test

The second task in my tension measurement was, personally, even worse than the first. I was asked to count sequentially decreasing from 2023 in steps of 17. Someone on the panel of unresponsive individuals interrupted me each instance I calculated incorrectly and told me to recommence.

I confess, I am inexperienced in mental arithmetic.

During the awkward duration attempting to compel my mind to execute arithmetic operations, all I could think was that I wanted to flee the increasingly stuffy room.

During the research, only one of the numerous subjects for the stress test did genuinely request to depart. The remainder, similar to myself, accomplished their challenges – presumably feeling different levels of embarrassment – and were given another calming session of background static through audio devices at the end.

Non-Human Applications

Perhaps one of the most unexpected elements of the technique is that, since infrared imaging record biological tension reactions that is innate in many primates, it can also be used in animal primates.

The researchers are currently developing its implementation within habitats for large monkeys, such as chimps and gorillas. They aim to determine how to reduce stress and boost the health of animals that may have been removed from distressing situations.

Scientists have earlier determined that showing adult chimpanzees recorded material of infant chimps has a relaxing impact. When the scientists installed a visual device close to the protected apes' living area, they observed the nasal areas of primates that viewed the footage increase in temperature.

Consequently, concerning tension, viewing infant primates playing is the contrary to a surprise job interview or an impromptu mathematical challenge.

Coming Implementations

Using thermal cameras in primate refuges could prove to be beneficial in supporting rescued animals to adapt and acclimate to a different community and unfamiliar environment.
