Method of performing automatic commissioning of a network

A lighting system has a controller which receives input information from physiological sensors associated with users in the area illuminated by the lighting system. Anxiety is detected of a user or users when in or approaching a particular region of the area, and the lighting is changed to reduce the anxiety. In this way, lighting changes only need to be made when there is a need based on the response of the particular users. The system thus 5 enables energy savings as well as more stable lighting conditions.
