Studies have shown that blueenriched light, which is emitted by gadgets like smartphones, tablets and laptops, can suppress the bodys release of melatonin at night. Melatonin is a key hormone that helps regulate your internal clock, telling your body when it is nighttime and when to feel sleepy. Blue light can disrupt that process, making it impossible for you to stick to a proper sleep schedule.
