Psychologists identify influence of human social interaction on sensitivity to physical pain

09.11.2010
Psychologists at the University of Toronto have shown that the nature of a social interaction has the ability to influence an individual’s sensitivity to physical pain. The discovery could have significant clinical implications for doctor-patient relationships and the general well-being of an individual on a daily basis.

“Dozens of studies over the past several decades have demonstrated the impact of inadequate social connectedness on numerous health outcomes, including cardiovascular health, immune function, post-surgical recovery, and lifespan,” says Terry Borsook, a PhD student in the Department of Psychology at U of T and author of a new study published in PAIN.

“Our study is among the first to show in humans that the perception of physical pain can be immediately impacted by the types of social experiences that people have in their everyday lives.”

In the study, healthy participants rated the intensity and unpleasantness of painful stimuli before and after engaging in a structured interaction with a trained actor who was instructed to be either warm and friendly or indifferent throughout the exchange. Participants who experienced the indifferent social exchange reported less sensitivity to pain after the interaction when compared to that measured before the exchange. Participants exposed to the positive social interaction, however, exhibited no change in pain sensitivity.

“While the analgesic effect resulting from a socially disconnecting event might seem like a good thing, we know from a great deal of research in animals and humans that social threats provoke the well-known fight-or-flight stress response, of which pain inhibition is a typical component.”

Borsook says that the results suggest that social relationships may be of such critical importance to human health and well-being that even a mild threat of disconnection can be stressful.

“This stress-induced analgesia evolved so that we can escape threats without being hobbled by pain. The pain reduction observed in our study is thus consistent with prior findings but what is remarkable about our results is that analgesia occurred in response to a type of experience that people experience in daily life, perhaps several times a day,” says Borsook. “If such everyday mildly unpleasant encounters are enough to provoke pain inhibition, then this suggests that many people may be exposed to chronic fight-or-flight responses, which can have many negative implications for health. This would be the case especially for people who are sensitive to social exclusion, such as those who feel lonely or fear rejection”

Borsook says that the results also have important clinical implications when it comes to seeing your doctor. “Health practitioners who are aloof, lack understanding, or are generally unresponsive to patients may provoke an analgesic response resulting in underestimated reports of pain, with insufficient pain control measures being a possible consequence.”

The findings are presented in a paper titled “Mildly negative social encounters reduce physical pain sensitivity”, published in the November issue of PAIN, the official publication of the International Association for the Study of Pain.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
