The 12 Best Ways to Fix Atrial Fibrillation with Sleep Whenever people try to get healthier, and no matter what the underlying reason for that effort, they almost always start with diet and exercise. Those are two very important factors, but without addressing a third factor—sleep—they are almost assuredly doomed to fail in their efforts to eat better and exercise more. In this article, I'm going to give you my 11 best ways to fix atrial fibrillation with sleep. Most of Us Are Really Bad at Sleep Let's face it, most of us are really bad at sleeping. And as a global community, it would appear, we’re actually getting worse at it, even as the science that demonstrates its importance to our lives has gotten more and more compelling. The World Health Organization has raised the possibility that sleep problems are an emerging global epidemic. In the United States, 70 percent of adults report insufficient sleep at least once a month, and 11 percent report insufficient sleep every night. For a while, it did seem like we were getting the message about the importance of sleep to our health. After a century of consistently diminishing sleep, researchers who study the way we slumber noticed something promising. From 2004 to 2012, the number of people who were getting less than six hours of sleep each night finally started to level out. Maybe, some thought, we were finally getting the message. Or maybe, others argued, we’d simple hit rock bottom. Either way, it seemed, we could finally start working to move the needle in the other direction. But when demographic sociologist Connor Sheehan and his collaborators dove into the subject in the late 2010s, they were dismayed by what they found. Yes, there had been a leveling out starting in 2004, but between 2013 and 2017 there was a significant shift. Far more people were reporting far less sleep. We hadn’t hit rock bottom after all. What changed? Among the most important factors are the devices we increasingly carry in our pockets, purses, and person. Closely coinciding with the quickly falling rate of adequate sleep was the rapidly rising rate of smartphone ownership, which went from 35 percent in 2011 to 77 percent in 2016. “Americans now spend more time looking at a screen,” Sheenan and his collaborators wrote, “and, due to the mobile nature of these devices, technology has increasingly entered the bedroom.” This isn’t just happening in the United States. More than 5 billion people around the world now have mobile devices, and more than half of those devices are a smartphone. Leading the way in the adoption of tiny, glowing screens is South Korea, where 95 percent of adults have a smartphone and where, perhaps not coincidentally, adults get nearly 40 minutes less sleep each night, on average, than their global counterparts. Because smartphones may be a cause of poor sleep, and also because these devices are increasingly equipped to detect the health consequences that result from poor sleep, it should come as no surprise atrial fibrillation diagnoses have skyrocketed in Korea in recent years. Why is Sleep so Critical for Atrial Fibrillation? The impact of poor sleep on AFib has been well documented. Even small interruptions of sleep quality and duration can increase the risk of atrial fibrillation by 18 percent, and people who experience insomnia are 30 to 40 percent more likely to develop atrial fibrillation. People who do not reach deep levels of sleep—the sort of sleep that is key to recovery—have an 18 percent increased risk of atrial fibrillation, and it worsens each time they wake up at night. It’s even worse for people with sleep disorders such as sleep apnea; they have a 200 to 400 percent increased risk of AFib over individuals without a sleep breathing disorder. And the problem is compounded once AFib actually develops; the presence of an abnormal rhythm can increase the risk of poor sleep quality, or short sleep, by three to four times.
