Artificial light from digital devices lessens sleep quality: Melatonin skyrockets when blue light is blocked was posted by the ScienceDaily blog on 7-28-17. This article briefly reviews the importance of sleep for various health functions, and summarizes the results for a study that found people using devices in the crucial hours before bedtime to have significantly reduced production of melatonin, by up to 50%!

The study also found that people who used special glasses that blocked blue light from devices, as measured by both self report and activity/sleep trackers, had more sleep, more restful sleep, and better energy during the day. ┬áThe authors of the study include recommendations for reducing the effects of blue light, including using special glasses to block that part of the light spectrum, using a device with a “night mode” that is capable of reducing blue light by changing the devices settings, or – most simply – just avoiding devices in the crucial hours before bedtime.
