    Transcutaneous vagus nerve stimulation (tVNS) is a non-invasive technique targeting the auricular region for neuropsychiatric conditions.

  • 2

    tVNS may address autonomic nervous system dysregulation, a key factor in various sleep disorders.

  • 3

    Current evidence supports tVNS's effectiveness in chronic insomnia, with multiple randomized controlled trials demonstrating significant improvements.

  • 4

    Preliminary studies suggest tVNS may have potential benefits for PTSD-related sleep disturbances, though findings are limited by small sample sizes.

  • 5

    No controlled trials have assessed tVNS's effects on obstructive sleep apnea, highlighting a gap in the current research.
