The new study will have an impact on how future pain research will be conducted and can lead to more effective chronic pain therapies.
A new study by researchers from Montreal and Toronto is the challenge of the old myth that men are more difficult to deal with pain than women.
The study showed that while women are somewhat more sensitive to physical pain in general, they are more deeply remembered by men and are more likely to be more burdened in the future to cope with the same pain. The findings should revolutionize the field of pain research and can lead to better treatment of chronic pain.
"It's interesting that if we wanted to assume that there was a gender difference, almost everyone – including myself – would have thought differently," said Jeffrey Mogil, a professor at the McGill Psychology Department. University and co-author of the study.
"Men should be stoic and a cat, and women should not be, and if anyone acknowledges that he was exposed to another day, they should be women. But it was not. These were men.
The researchers experimented on laboratory mice and humans and observed similar results.
The researchers experimented on laboratory mice and humans and observed similar results. The researchers used low levels of heat for the last paws of mice. For 41 men and 38 women, the heat was applied to the forearm.
In order to make the pain unforgettable, the mice soon received an injection of vinegar, which caused gastric pain for about 30 minutes. Human test subjects had a tightly inflated blood pressure cuff and exercised their hands for 20 minutes, with short-term, but painful pain.
The next day, human subjects were subjected to the same degree of pain, but Men rated heat pain higher than the previous day and higher than women. Researchers observed the same differences in day-to-day detection in males against females. The findings were published this week in Current Biology.
"Do men remember (pain) and women are not, or remember, but only in men is a memory that causes stress," explained Mogil.
The findings show that memory plays a role in chronic pain.
"This is an important finding because more and more evidence suggests that chronic pain is a problem to the extent that you remember it, and this study is for the first time that such a recurring pain has been shown through the translation – both the murmur and the human subject – said Loren Martin, the first author on paper and a Psychology Assistant at the University of Toronto, Mississauga.
"If you remember that pain is a driving force for chronic pain and we understand how pain reminds us, we may be able to help some people by directly addressing memory mechanisms."
