Summary:
- This article discusses research findings that suggest the hormone estrogen may trigger the body to produce its own natural opioids, or painkillers, after an injury.
- The study found that when female rats experienced an injury, their bodies produced more of the natural opioid enkephalin, which helped reduce pain. This response was not seen in male rats.
- The researchers believe this natural pain relief mechanism could explain why women tend to experience less chronic pain than men after similar injuries. Understanding this process could lead to new pain management treatments.
