This alarm clock mimics the light and colour of a real sunrise so when you open your eyes you feel properly awake and refreshed. Waking like this helps to regulate your sleep-wake cycle and has even been shown to boost mood, energy and productivity levels for the rest of the day. This product is the ideal choice if you’re new to this type of light therapy. It has the essential 30-minute sunrise and sunset plus a couple of popular customisations; choice of final light intensity for the sunrise and a nightlight option for the end of the sunset - great for kids. This clock provides fully adjustable bedroom lighting, bright for reading or a relaxing soft glow. As your room gets dark, the light-sensitive display switches off to help you switch off. Tap-control snooze is another nice touch.
