Temperatures are swiftly falling across the United States — which for some people is a prompt to curl up in a warm blanket and sleep until spring. However, many Americans struggle with falling asleep. Why? One reason is our relationship with technology.
The link between technology and sleep rests with our circadian rhythm — the cycle that determines when we feel tired or awake. According to a Harvard Medical School study, our phones emit short-wavelength blue light that sparks cortisol production, which helps us stay alert, and suppresses melatonin, which helps us fall asleep.
Studies also show that the average American looks at their phone 46 times per day and spends about 11 hours a day on smartphones, tablets and computers. Ninety percent of Americans also reported using an electronic device during the hour before they went to sleep.
The infographic — created by Nursing@Georgetown’s Online FNP Program — further explains how short-wave blue light affects our ability to sleep and provides tips on how to reduce technology use before bed.
