What this trial studies

This clinical trial aims to investigate whether applying electrical stimulation to the brain during naps can enhance specific brain activities associated with REM sleep, potentially improving emotional health and stress resilience. Participants will undergo multiple naps while wearing a high-density EEG cap, with varying stimulation parameters to identify the most effective methods for enhancing REM sleep. The study consists of two phases, including randomized conditions and assessments of emotional regulation before and after the naps.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults aged 18-50 who regularly take naps at least once a week.

Not a fit: Patients with a history of neurological disorders, seizures, or unstable medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved emotional health and resilience to stress for individuals who regularly take naps.

How similar studies have performed: While the approach of using electrical stimulation during sleep is innovative, similar studies have shown promise in enhancing sleep quality and emotional regulation.
