The Impact of E-Readers on Sleep Patterns
E-readers, such as Kindles and iPads, emit blue light that can disrupt sleep by delaying the circadian rhythm, interfering with melatonin production, impacting morning alertness, making it harder to fall asleep at night, and reducing time spent in deep stages of sleep. However, electronic ink readers like Kindles emit less blue light compared to LED or LCD e-readers like iPads. If using an e-reader before bed, it is recommended to follow good sleep habits such as avoiding screens within an hour before bed, using dark or night mode, and considering blue-light-blocking glasses. Ultimately, the impact on sleep varies for individuals, and if e-readers do not affect sleep, there is no need to change bedtime routines.
