A guided meditation system, such as a virtual reality (VR) guided meditation system, provides biofeedback. Wearable devices (e.g., fitness trackers) record information about a physiological state of a user (e.g., heart rate, blood pressure, sleep, and activity data). Performing guided meditation exercises may help users improve their physiological state (e.g., by decreasing a user's heart rate). The VR guided meditation system automatically retrieves physiological state information from wearable devices or third party applications before and/or after a user performs guided meditation exercises. Based on the retrieved information, the VR guided meditation system provides biofeedback related to effects or potential correlations between an exercise and the user's physiological state. In particular, the biofeedback indicates a certain type of meditation, certain VR environment location, or certain meditation duration that is likely to improve the user's physiological state. The VR guided meditation system also can provide recommended exercises to the user.
