A visit duration control system comprises a sensor ( 10 ) for sensing one or more physiological parameters of a person over time allowing the quantification of stress load of said person, a visit detector ( 20 ) for indicating the start of a third party's visit to said person, a processor ( 30 ) for determining said person's stress load from said one or more physiological parameters during said third party's visit and a signaling unit ( 40 ) for issuing a warning signal if said stress load exceeds a predetermined level. |
