To provide a device that helps a user reach a less stressful state, namely a meditative state or "flow" as efficiently as possible.SOLUTION: A respiratory synchronization lighting device 100 helps a user adjust a breathing rate of the user himself / herself by moving a light source 110 relative to a fixed shade or a cover 180. The shade or the cover is optionally perforated or has an integrated shielding pattern to partially shield light produced by the light source. This results in the creation of a shadow pattern on nearby surfaces. The shadow pattern moves over a surface surrounding the device corresponding to the movement of light with respect to the cover. This results in a pattern of periodically moving shadows over the nearby surfaces. This pattern is time-adjusted to match an ideal breathing rate of the user, thereby helping the user slow his / her breathing and reach a calm meditative state.SELECTED DRAWING: Figure 1
