The consequences of not getting enough sleep are evident to all of us—and yet we’re constantly staying up later than what our internal biological clocks are telling us. A new study shows the elusive nature of what’s to blame.
A DNA analysis of nearly 90,000 23andme customers suggests our preference for early mornings may be rooted in our genes. The study also suggests that night owls are at greater risk of depression and other health issues. But those findings come with a couple of caveats.
Teeth grinding is a problem that affects nearly one in ten individuals, yet many of us don’t even realize we’re doing it. And that’s a problem given just how harmful it can be to our health. Here’s how to find out if you grind your teeth when you sleep—and why it’s something you shouldn’t ignore.
Skipping a night of sleep to work on a project or study for an exam is something many of us have done at one time or another. But what does sleep deprivation actually do to the brain? A new study shows that all-nighters are not without neural consequences—some of them potentially longterm.
It’s no secret that drinking coffee shortly before bedtime disrupts sleep, but a new study suggests that caffeine can actually affect our body’s internal clock, pushing back our natural rhythms by nearly an hour.
New findings indicate nearly one in five college-age students has been startled awake by an abrupt, loud noise that doesn't actually exist. Known as "exploding head syndrome," the psychological condition appears to be more common and disruptive than previously thought.
A new Harvard study is re-affirming the assertion that reading light-emitting e-books before bed, like computer tablets, could have a detrimental effect on sleep, which can in turn lead to serious health problems.
If animals dream like us, where do they go in their slumber? Some scientists have discovered that we can peer into the minds of sleeping cats, birds and other creatures to find out.
"Almost all other animals are clearly observed to partake in sleep, whether they are aquatic, aerial, or terrestrial," wrote Aristotle in his work On Sleep and Sleeplessness. But do other animals dream? On that the Greek philosopher also had an opinion.
"Sometimes," said Walt Disney, "we can recognize ourselves in animals. That's what makes them so interesting." He was more right than he knew. One group of people may have had particular insight into human sleep behavior and its disorders: Disney animators.
Imagine the person sleeping next to you suddenly sitting bolt upright and screaming wildly. You try to console them, but they don't respond. Then, after a few minutes, they fall back asleep as if nothing happened. No, they didn't have a nightmare. It's called a night terror. Here's what you need to know about this…
And not figuratively, either. Sometimes people have found that certain emotions literally cause their muscles to unhook from their brains. They collapse entirely. This is not some strange disease, or weakness — tt's the misapplication of a necessary function.
Extensive studies conducted by universities in the US and Sweden show that a certain dose of radio frequency before bedtime causes insomnia. While there is plenty of number crunching yet to come to determine the exact relationships between exposure to 884MHz RF and loss of sleep, the key message from one of the…
