Every night, millions of Americans are affected by insomnia. Insomnia presents in various forms, including difficulty falling asleep at night and frequent waking up during the sleep cycle, resulting in feeling tired during the day. What are the causes of insomnia? And how do factors like screen time and caffeine consumption during the day impact our sleep? We spoke to Michael Breus, PhD, DABSM, clinical psychologist and diplomate of the American Board of Sleep Medicine, about the common reasons for sleep disruption, the role our chronotypes play in insomnia, the ways we can track our sleep cycle, what we should be asking our doctors when it comes to sleep, and a five-step plan we all can use on the path to more restorative sleep.
