Find a quiet, comfortable place where you can lie down or sit without being disturbed. Close your eyes and take a few deep breaths, focusing on your breathing. Starting with your toes, tense the muscles in that area for about 5 seconds. Slowly release the tension, focusing on the sensation of relaxation for about 10 seconds. Move up to the next muscle group (e.g., calves, thighs) and repeat the process. Continue this pattern through all major muscle groups, including your abdomen, chest, arms, and face.
