CNN: “How Your Smart Phone Affects Your Sleep”By Sanjay Gupta, MD1 min, 31 secDr. Gupta explains in this video how using our smart phones before bed can hurt our chances of a good night’s sleep. He says that looking at emails or other content on our phones can "take our brains from 0 to 60" (in terms of arousal) very quickly. In addition, the light from the phone (and other electronics) can disrupt our circadian rhythms. The light can inhibit the production of melatonin, a chemical in the body that's involved in helping us fall asleep. The vast majority of the ADHD clients I work with have problems with regulating sleep and oversleeping or insomnia also is frequently a symptom of depression or anxiety.
