TUNED LED lighting has halved the number of sleep disturbances among older residents in a long-term care home, a study has shown. The experiment, at a 99-bed nursing home in Sacramento, California, showed that, on average, residents experienced 3.6 nighttime sleep disturbances with static lighting compared to 1.8 with tuned lighting. Additionally, the researchers – from...
Circadian Lighting

SCIENTISTS say they have identified the exact wavelength of light which controls the sleep-wake cycle of humans.  A paper, published in the Journal of Biological Rhythms today, reveals that 477 nanometres is the most potent light to control people’s circadian rhythm.  The researchers have dubbed it ‘Circadian Blue’. The study has major implications for how...
