The present disclosure pertains to a system and method for providing sleep positional therapy and paced breathing to a user for a sleep session. The system and method may be used to treat positional obstructive sleep apnea, positional snoring, and/or other conditions to improve sleep onset latency, relaxation, reduce blood pressure, and/or improve other physiological characteristics. The system includes a posture sensor, a sensory stimulator, a controller, and/or other components. The system is configured to generate information related to a posture of the user, determine whether the posture of the user has breached a posture threshold, provide vibrations to the user to prompt the user to change posture, and lead the user through a paced breathing exercise to help the user fall asleep.
