A system for therapy may include a mask (200) for a patient having a frame, cushion, forehead support and a light (100). The mask is connectable to a respiratory treatment apparatus, such as a flow generator, to receive breathable gas for a respiratory therapy. The light may also be connected to the power system and/or control system of the apparatus. A light may also be included in a module, such as a docking station, for a respiratory treatment apparatus. The lights may be controlled by one or more processors, and may be responsive to detected conditions, to assist with therapy. For example, the light may be turned on at a predetermined time or may be synchronized with the patient's sleep state, to assist in waking up the patient or re-setting the patient's circadian rhythm. Other components, such as sound and aroma generators of the system, may also be controlled for such therapies.
