The unique combination of light and sound inspired by the sunrise in nature of the Philips Wake-up Light wakes you up in a more natural way. This makes it easier for you to get up and feel ready for the day. The light intensity gradually increases over 30 minutes to a bright yellow light. This slow change stimulates the body, allowing you to wake up naturally. Together with the room-filling light, the natural sound of your choice enhances your waking experience, ensuring you are ready for the day.
