How Screens Are Impacting Sleep Quality

Excessive screen time, particularly before bedtime, can significantly disrupt sleep patterns and quality. The blue light emitted by screens, such as those on smartphones, tablets, and computers, interferes with the production of melatonin, a hormone responsible for regulating our sleep-wake cycle. When exposed to screens, especially in the evening, our bodies may perceive this artificial light as daylight, making it difficult to fall asleep.

Additionally, engaging in stimulating activities like watching intense movies, scrolling through social media, or playing video games can increase cognitive arousal, making it challenging for the brain to wind down and transition into a restful state. This heightened mental alertness can delay the onset of sleep and reduce overall sleep duration.

The constant connectivity facilitated by screens also tempts us to stay engaged with digital devices well into the night, leading to irregular sleep schedules and a lack of proper sleep hygiene. Over time, these habits can accumulate and contribute to chronic sleep deprivation, which has various negative effects on physical and mental health.

To ensure better sleep, it's advisable to establish a "screen curfew" by reducing screen time at least an hour before bedtime. This simple adjustment can help protect the quality and quantity of our sleep, ultimately promoting overall well-being.
