Effect of brainwave entrainment on sleep quality among MBBS students in India

Brainwave entrainment (BWE) synchronizes neural oscillations using rhythmic auditory and photic stimuli. Therefore, it is of interest to study the immediate effect of a single delta wave BWE session using the Brain Tap headset on sleep parameters among medical students. Hence, twenty six participants underwent one BWE session, with sleep metrics recorded pre and post session using a smart watch. Delta wave BWE was associated with significant improvements in sleep score, total sleep duration, light sleep and deep sleep, with reduced nocturnal awakenings. Thus, we show delta frequency BWE may serve as a non-pharmacological aid for enhancing sleep quality.
