The most notable consequence of technology on sleep is the effect of blue light, which interferes with the production of melatonin, the hormone responsible for regulating sleep. Prolonged exposure to screens in the evening can lead to overstimulation, making it difficult for individuals to unwind and fall asleep. This, in turn, reduces sleep time, leaving people feeling fatigued and less rested. Additionally, constant notifications and the temptation to check devices before sleep can further delay bedtime, causing disruptions to the natural sleep cycle. While technology offers solutions like sleep-tracking apps, it is essential to manage screen time and maintain healthy sleep habits to mitigate these negative effects on sleep quality.
