Abstract in brief

  • Evening use of light-emitting eReaders can delay sleep, reduce alertness the next morning, and disrupt the body's internal clock by suppressing melatonin production.
  • Using electronic devices before bed has become common and is linked to poorer sleep quality and duration, which can negatively affect overall health.
  • The study found that reading on a light-emitting eReader in the evening takes longer to fall asleep, delays circadian timing, and reduces next-morning alertness compared to reading a printed book, highlighting potential health risks of using such devices at night.]
