1. A lighting system comprising:
at least one light source, the at least one light source configured to emit light having a plurality of emission characteristics; and
a control system in communication with the at least one light source, the control system comprising at least one sensor configured to detect an aspect of a subject in an environment illuminated by the at least one light source, the control system configured to randomly vary at least one of the emission characteristics of the light emitted by the light source, the at least one of the emission characteristics being randomly varied by at least an amount that is perceptible to the subject, based on the detected aspect, in response to a noise signal having an amplitude or a frequency falling outside of a range of noise signal amplitudes or a range of noise signal frequencies,
wherein the aspect comprises one or more physiological characteristics of the subject.
