This study will examine the immediate (acute) effects of a single, 30-minute body awareness session on brain activity and interoceptive accuracy in healthy young adults aged 18-25. Participants will be randomly assigned to one of two groups: an intervention group, which will complete a structured body awareness exercise based on Basic Body Awareness Therapy, or a control group, which will rest quietly for the same amount of time without any specific instructions.
Before and after the session, brain activity will be recorded using a portable, 8-channel EEG device, and interoceptive accuracy will be measured with a heartbeat perception task, in which participants try to count their own heartbeats without checking their pulse. The main goal is to determine whether a single body awareness session produces measurable changes in EEG brain wave patterns (theta, alpha, beta, and gamma bands) and in the accuracy of heartbeat perception, and whether these two types of change are related to each other.

Participants and the person delivering the intervention/control session cannot be blinded to group assignment due to the nature of the intervention. However, outcome assessors - specifically, the researchers responsible for EEG signal preprocessing, feature extraction, and interoceptive accuracy scoring - will be blinded to group allocation. Group codes will be masked during data analysis to minimize assessment and analytic bias.
Participants in this arm will receive a single, approximately 30-minute structured session based on Basic Body Awareness Therapy principles, guided by a physiotherapist or researcher trained in body awareness applications. The session includes preparatory orientation, supine body scanning and contact awareness, breath awareness, slow symmetrical movement awareness, seated midline and postural awareness, standing weight-shift awareness, and a closing integration period.
Participants in this arm will undergo a quiet/neutral resting session of the same duration and in the same environment as the intervention group, without receiving any body-awareness-related instructions, guidance, breathing exercises, or movement tasks. This arm serves to control for effects attributable to time, environment, rest, or eye closure alone.
