Acute Effects of Progressive Muscle Relaxation on Brain Waves

Participants will undergo approximately 30 minutes of Progressive Muscle Relaxation (PMR). Prior to the session, a brief introduction to the basic concepts of PMR will be provided. Participants will be instructed to close their eyes and focus on the sensations in their muscles. Following verbal instructions, they will sequentially contract and relax 14 major muscle groups from top to bottom. For each muscle group, participants will be asked to contract the muscles as strongly as possible for 7 seconds, followed by a 45-second relaxation period. This process will be repeated twice for each muscle group.

Rest in a semi-recumbent position with eyes closed for 30 minutes, without any additional intervention.
