Blue light sleep disruption has become increasingly common as people spend more time using digital devices during the evening. Screen light exposure from smartphones, tablets, laptops, and televisions can interfere with the body's natural sleep cycle by sending signals that mimic daylight.
The human body relies on a carefully regulated circadian rhythm to determine when to sleep and wake. When blue light exposure occurs late at night, melatonin suppression can delay the body's natural sleep timing. Over time, this shift in the sleep cycle can reduce sleep quality and leave people feeling less rested the next day.
