Systems and methods are provided that provide respiration entrainment cues to a user to encourage relaxation or a sleep state. The entrainment cues may be audible, visible, or tactile (or any combination). The entrainment cues include a rhythmic component associated with a target respiration rate and may include sub-components associated with a target breath architecture, such as an inhale-exhale cycle. The systems and methods detect the user's respiration to determine whether the user's respiration matches the entrainment cues or whether the user has fallen asleep.
