Apparatus, systems and methods for affecting the physiological condition of a user

An apparatus for affecting the physiological condition of a user, the apparatus comprising:

• a housing having an interior space;
• at least one light source positioned in the interior space;
• a window mounted to the housing and configured to allow light from the at least one light source to pass through the window and outwardly from the housing;
• at least one sensor having a field of view that extends outwardly from the window and outwardly from the housing;
• and
• a controller in communication with the at least one light source and the at least one sensor;
• wherein the controller and the at the least one light source are cooperatively configured to control light emitted from a first portion of the at least one light source so that brightness of the light emitted from the first portion changes through a time cycle that is serially repeated for guiding breathing of a user positioned at least partially in the field of view of the at least one sensor:
• wherein the controller and the at least one sensor are cooperatively configured to detect at least one physiological condition of the user indicating present breathing rate;
• and
• wherein the controller and the at the least one light source are cooperatively configured to control, during the brightness of the light from the first portion changing through the time cycle, light emitted from a second portion of the at least one light source indicating the present breathing rate of the user in real time, wherein color of the light emitted from the second portion is different than color of the light emitted from the first portion through the time cycle.
