How Technology Shapes Your Sleep Quality
The Impact of Devices on Rest
Smartphones, tablets, and laptops emit blue light, which suppresses melatonin, delaying sleep. A study in the *Journal of Sleep Research* found that two hours of screen time before bed can delay sleep onset by up to an hour. Understanding technology’s effects helps you reclaim restful nights.
