Power Nap With TES-TI
Purpose
The goal of this clinical trial is to find out whether stimulating the brain with electrical current during naps can increase certain kinds of brain activity that happen during sleep and lead to improvements in mental fatigue. Participants will attend 2 study visits, each of which may last up to 4-5 hours. During these visits, participants will wear a high density electroencephalography (hdEEG) cap and take a nap.

Detailed Description
This project aims to use transcranial electrical stimulation with temporal interference (TES-TI) to enhance the production of sleep slow waves, boosting the restorative power of sleep and mitigating cognitive impairment (mental fatigue) and its underlying cause (brain fatigue).
