Light at the start of the day is the most effective way to reset your internal clock and the daily cycle of hormones, metabolism and sleep. The Bodyclock Glow 150 from Lumie is a Class 1 graded medical device that will introduce you to the benefits of sleeping and waking with light, so that you can experience a more regular sleep and wake pattern.

Bodyclock Glow 150 wakes you naturally at the alarm time when the light is at its brightest. Set your preferred final light intensity and wake up to a warm glow or a bright, sunny room. Choose from one of the wake-up sounds if you'd like an extra alarm. Waking up with gradual light has been proven to boost mood, productivity and energy levels, so that you feel brighter and ready for the day ahead.

Wind down gradually with a sunset feature lasting 20, 30 or 45 minutes. Fading light is a signal for the body to produce melatonin ready for sleep, so the sunset makes you naturally drowsy. Realistic lighting fades through pink, orange, red then turns off or stays at a soft glow if you set the nightlight feature.

This product is recommended for SAD and winter blues sufferers as it helps to regulate your sleep and wake cycles and is a great complement to bright light therapy.

Quiet Mark approval means sounds are kept to a minimum and you're not disturbed by excess noise. Handy if you're in an open-plan living space.

Key features include: Light that mimics the colours of a real sunrise or sunset for 20, 30 or 45 minutes, nine wake up and sleep sounds, including white noise, adjustable sunrise light intensity, nightlight and a fully dimmable bedside light, light-sensitive auto-dimming display.
