    Sleep disturbances affect 10%–30% of adults globally, leading to significant health burdens including reduced quality of life and increased cardiovascular risk.

  • 2

    Non-invasive electrical stimulation (NIES) techniques are emerging as promising non-pharmacological interventions for improving sleep quality.

  • 3

    Existing systematic reviews on NIES for sleep show considerable variability in methodological quality, populations, and intervention types.

  • 4

    This umbrella review aims to synthesize evidence from systematic reviews and meta-analyses on NIES for sleep outcomes, assessing methodological quality and evidence patterns.

  • 5

    The review will follow JBI guidelines and include subgroup analyses by intervention type and demographics, with the primary outcome being subjective sleep quality.
