I have an interesting study that states the ability to withstand more pain is an adaptive process. We all know that it is. We know it does it with pain because we endure a vast amount of it and we cope with it as time passes. Not even sure how long it takes before our tolerance begins to grow but it is a natural process. This suggests a physical adaptive process. Although, since it is a small study they would need to dig deeper.
The small study was published in Pain.
When the researchers used heat on the men and women’s skin to induce pain, they found that the more opioid receptors they had, the greater their ability to handle pain. These receptors were higher among the people with arthritis, which the researchers say suggests that this increase is an adaptive response, possibly to make it easier to deal with the chronic pain that comes with such a condition.
The researchers did not prove that arthritis pain increases the numbers of these receptors, but lead study author Christopher Brown, a senior research associate at the University of Cambridge, said in a statement that “although the mechanisms of these adaptive changes are unknown, if we can understand how we can enhance them, we may find ways of naturally increasing resilience to pain without the side effects associated with many pain-killing drugs.” Time health
