Summary

This study tested whether cognitive behavioral therapy for insomnia (CBT-I) can improve sleep and reduce pain in women with fibromyalgia. 131 women with both conditions received either CBT-I or sleep hygiene education. Researchers measured sleep quality, pain sensitivity, and brain changes to see if treating insomnia helps ease chronic pain.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cognitive Behavioral Therapy for Insomnia (CBT-I)
What this could lead to
If it works, this could point toward a non-drug way to improve sleep and reduce pain in women with fibromyalgia.
What could go wrong
This is a completed study with 131 participants, so results are limited in size. The treatment may not work for everyone, and benefits might not last long-term.
