Lumie Bodyclock Luxe is an alarm clock that 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. It's the most advanced Bodyclock wake-up light with high-quality speakers for streaming your own music or radio via Bluetooth, and a USB port for more audio files or for charging your phone. It also comes with over 20 wake-up and sleep sounds, from classic birdsong and waterfall recordings to background café chat and fading thunder. At night, Bodyclock Luxe has a fading sunset to help you relax and a new low-blue light feature especially for bedtime lighting. Alerting blue light is kept to a minimum so you're ready for sleep and can drift off easily. Other features include a nightlight setting, 7-day alarm and dimmable bedside lighting. A wake up light like Bodyclock Luxe 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).
