The present invention relates to a system for monitoring light and sound impact on a patient. It comprises a light capturing unit (2) for capturing ambient light at the person over time and a sound capturing unit (3) for capturing ambient sound at the person over time. A threshold unit (6, 9) generates and issues a trigger signal if the brightness of captured ambient light exceeds a brightness level and/or if the sound level of captured ambient sound exceeds a sound threshold. A stress level processor (15) determines the stress level of the person. A storing unit (10) stores, in response to a received trigger signal, snippets of ambient light and ambient sound captured around the time moment of receiving the trigger signal and snippets of stress level information of the person around the time moment of receiving the trigger signal. A review unit (11) is provided to review stored snippets of ambient light, ambient sound and stress level information allowing to identify the root cause of the ambient light and ambient sound stored in a reviewed snippet and to derive guidance information indicating how to avoid such light and/or sound caused by an identified root cause.
