The article argues that using a smartphone before bed can negatively affect sleep quality and overall well-being. Bright screen light may interfere with melatonin production, making it harder to fall asleep and reach deep, restorative sleep stages. Keeping a phone nearby can also keep the brain on alert through notifications, vibrations, and constant access to information. Over time, poor sleep may contribute to fatigue, difficulty concentrating, irritability, and reduced productivity. Experts recommend creating distance between technology and sleep by avoiding screens before bedtime, moving phones out of the bedroom, and using relaxing activities to help the mind unwind naturally.
