More gentle than traditional jarring alarms, this clock uses gradually increasing light, stimulating aromas, and peaceful nature sounds to awaken sleepers. At 30 minutes before wake-up, the clock's light begins to glow softly, brightening over the next half-hour. The warmth from the lamp releases faint aromatherapy scents into the air to stimulate the olfactory senses. Fifteen minutes before wake-up, the clock generates your choice of six soft nature sounds, such as ocean surf or songbirds.
