A computer system displays a first computer-generated experience that includes displaying one or more virtual elements in a three-dimensional environment with a first appearance. While displaying the one or more virtual elements with the first appearance, the computer system receives biometric data corresponding to respiration of a first user. In response to receiving the biometric data: in accordance with a determination that the biometric data corresponding to the respiration of the first user meets first criteria, the computer system displays the one or more virtual elements in the three-dimensional environment with a second appearance that is different from the first appearance; and in accordance with a determination that the biometric data corresponding to the first user does not meet the first criteria, the computer system continues to display the one or more virtual elements in the three-dimensional environment with the first appearance.
