Philips Smart Sleep features a wake up alarm with nature sounds and a colored sunrise simulation. The light therapy emits morning light that changes from a soft red to warm orange to a bright yellow, gentle and gradually waking users with a natural light. The alarm comes with a choice of five different natural and calming wake up sounds. It also has an FM radio and snooze feature. For the Sunset, at nighttime, the bedside light dims gradually to promote natural restful sleep. This is a fabulous gift of anyone that is NOT a morning person and has trouble getting out of bed in the morning, or someone who has a lot of trouble falling asleep at night.
