The Blue Light Blackout challenge encourages families to turn off all screens by 9 PM every night, promoting better sleep for children and teens. Adequate sleep is crucial for school-age kids as it supports their physical health, emotional well-being, and cognitive function, helping them stay focused and perform well in school. The initiative emphasizes the importance of reducing blue light exposure before bedtime, as it can interfere with the body’s natural sleep-wake cycle, making it harder to fall asleep and get restful sleep. By turning off screens early, families can help their children develop healthier sleep habits, leading to improved overall well-being and academic success.
