A new scientific study has identified a crucial, previously overlooked factor that can significantly intensify chronic pain: disrupted sleep. Researchers found that even brief nocturnal awakenings markedly increase pain sensitivity, especially in women, potentially offering a new perspective on chronic pain management.

Researchers from Aalborg University have presented compelling evidence that even short, intermittent awakenings during the night can amplify an individual`s sensitivity to pain. Their significant findings, recently published in the esteemed European Journal of Pain, highlight a particularly pronounced effect among women.
The study involved 59 healthy volunteers who participated in an observational experiment spanning three nights. To simulate sleep disturbances, participants were intentionally roused three times per night and asked to complete simple cognitive tasks. Measurements of their pain sensitivity were taken both before and after this period of interrupted sleep. The results conclusively demonstrated that even minor yet regular interruptions to sleep led to a notable increase in pain perception. Strikingly, this effect was considerably more pronounced in female participants compared to their male counterparts.
The authors of the study suggest that these findings could offer a vital explanation for why women constitute a disproportionate number—up to two-thirds—of individuals afflicted with chronic pain. While traditional pain management strategies typically encompass physical therapy, pharmaceutical interventions, and surgical procedures, the scientific community is increasingly recognizing the pivotal role of sleep in influencing the efficacy of pain treatment. Drawing a parallel with mental health conditions such as depression and anxiety disorders, where the normalization of sleep is often the foundational step towards recovery, the researchers propose that improving sleep quality could likewise emerge as a key strategy in mitigating chronic pain symptoms.
