This IC I put the red light on the back of my neck. I felt a gentle tingling and pressure in my face and jaw, and my jaw slowly began to relax and my teeth separated gently. Almost as if my body wanted to stop clenching. Very interesting experience!
這次我把紅光照射在後頸。我感覺臉部和下巴有輕微的刺痛感和壓力感，下巴慢慢放鬆下來，牙齒也輕輕分開。感覺就像身體想要停止緊咬牙關一樣。真是非常奇妙的體驗！
