Can a simple meditation ease PTSD and sleepless nights?
NCT ID NCT06888336
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a guided meditation called yoga nidra is practical and helpful for people with PTSD and insomnia. Sixty adults who had experienced a stressful or traumatic event and had trouble sleeping took part. They listened to online recordings daily for 8 weeks, and the researchers checked if they stuck with it and if their sleep and PTSD symptoms improved.
