A smartphone within reach creates constant opportunities for sleep interruption. Even when notifications are silenced, many people remain psychologically connected to their devices. A brief awakening during the night can quickly turn into checking emails, scrolling social media, or reading messages.
What might seem like a one-minute glance often becomes much longer.
These interruptions fragment sleep and reduce the amount of restorative rest the body receives.
Researchers emphasize that uninterrupted sleep cycles are essential for physical recovery, memory consolidation, emotional regulation, and cognitive performance.
