First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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 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.
