Using electronics within an hour of going to sleep has been shown to negatively impact sleep quality, quantity, and daytime alertness. Almost all Americans regularly use electronics like TVs, computers, phones, and video games before bed. This is problematic because the blue light from screens suppresses melatonin production and using engaging devices too close to bedtime can mentally stimulate the brain and disrupt sleep associations with the bedroom. It is recommended to avoid electronics in the hour before sleep to promote better sleep health.
