A system configured to provide sleep positional therapy and guidance for paced breathing to a user for a sleep session, the system comprising: one or more posture sensors configured to generate output signals conveying information related to a posture of the user; one or more sensory stimulators configured to provide sensory stimulation to the user; and a controller coupled to the one or more posture sensors and the one or more sensory stimulators, the controller configured to: determine, based on the output signals, whether the posture of the user has breached a posture threshold, and, responsive to a breach, cause the one or more sensory stimulators to provide first sensory stimulation to the user to prompt the user to change posture such that the posture of the user no longer breaches the posture threshold; characterized in that the controller is further configured to determine a relative agitation state of the user, responsive to determining that the posture of the user no longer breaches the posture threshold, cause the one or more sensory stimulators to provide second sensory stimulation that guides the user through a paced breathing exercise, and determine whether to cause the one or more sensory stimulators to provide second sensory stimulation based on the relative agitation state. one or more posture sensors configured to generate output signals conveying information related to a posture of the user; one or more sensory stimulators configured to provide sensory stimulation to the user; and a controller coupled to the one or more posture sensors and the one or more sensory stimulators, the controller configured to: determine, based on the output signals, whether the posture of the user has breached a posture threshold, and, responsive to a breach, cause the one or more sensory stimulators to provide first sensory stimulation to the user to prompt the user to change posture such that the posture of the user no longer breaches the posture threshold; characterized in that the controller is further configured to determine a relative agitation state of the user, responsive to determining that the posture of the user no longer breaches the posture threshold, cause the one or more sensory stimulators to provide second sensory stimulation that guides the user through a paced breathing exercise, and determine whether to cause the one or more sensory stimulators to provide second sensory stimulation based on the relative agitation state. determine, based on the output signals, whether the posture of the user has breached a posture threshold, and, responsive to a breach, cause the one or more sensory stimulators to provide first sensory stimulation to the user to prompt the user to change posture such that the posture of the user no longer breaches the posture threshold; characterized in that the controller is further configured to determine a relative agitation state of the user, responsive to determining that the posture of the user no longer breaches the posture threshold, cause the one or more sensory stimulators to provide second sensory stimulation that guides the user through a paced breathing exercise, and determine whether to cause the one or more sensory stimulators to provide second sensory stimulation based on the relative agitation state.
