Bodyclock Go is an alarm clock that recreates a gradual sunrise that wakes you naturally so when you open your eyes you feel awake and refreshed. Waking up 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. If you’re not a morning person, it’s a truly bright start to the day. You can wake up with a 20, 30 or 45 minute sunrise. And, for those who like the reassurance of an alarm, there are five wake-up sounds to choose from including Big Ben chimes and a perky dawn chorus. At the end of the day, the fading sunset is the natural way to unwind and fall asleep. Extra features include a nightlight setting. A wake-up light like Bodyclock Go is not only a much nicer way to start the day – especially on dark, winter mornings – it can help beat the winter blues and is a useful complement to a lightbox in treating SAD (seasonal affective disorder). Warning: Please note that this item is not suitable for use with CFL type energy saving bulbs.
