This alarm clock simulates a sunrise to help you wake up naturally. The sunrise starts 30 minutes before your alarm time and slowly brightens over half an hour to wake you gently. The snooze button gives you another 5 minutes in bed. If you like the reassurance of an audio alarm, this alarm has an optional alarm beep or a choice of 5 natural sounds, including birdsong and a purring kitten. When you’re ready to sleep, touch the sunset button and the light will dim over 30 minutes to help you relax. The display can be switched to low or off if you prefer.
