For years, sleep experts have warned about the dangers of blue light from our devices and how it interferes with our sleep. Manufacturers of these devices have responded by adding night modes to our laptops, tablets and phones that reduce the blue light emitted. But a new study published in the journal Sleep Health suggests these night modes do not improve sleep. Researchers from Brigham Young University and the Cincinnati Children’s Hospital Medical Center found little difference in the sleep duration and quality of subjects who used these devices for an hour before bed, with or without these night modes. The researchers argue that the stimulation provided by using these devices might affect sleep more than their blue light. If you really want to improve your sleep quality, you should consider not using a device at all before bedtime.
