After examining 13 million hours of light exposure data, researchers found that experiencing bright light during the dark hours can significantly increase the risk of heart failure and heart attack. The effect was most notable in younger adults.

A new study has revealed how the brain uses the night to flood the body with pulses of growth hormone to repair muscles, strengthen bones and balance metabolism. And why cutting corners on sleep undermines your physical health short- and long-term.

If you deal with waves of daytime drowsiness, you might be among the estimated 33% of the population suffering from excessive daytime sleepiness. In the largest study of its kind, scientists have uncovered the condition's unique biological fingerprint.

A huge international study has identified a weekly disturbance in one of the world’s most common sleep disorders, obstructive sleep apnea. Introducing “social apnea” – when the severity of the disorder jumps by nearly 20% on these specific nights.

An intriguing new study has found that symptoms of obstructive sleep apnea could be significantly reduced by regular sessions of blowing through a conch shell. Now, researchers are expanding the work, taking Triton's trumpet to test on a larger scale.

Not all physical activities are created equal when it comes to a good night's sleep. A new study has uncovered the four practices that can significantly help different aspects of sleep disorders, without medical intervention. And they're all free.

Whether it's reading a book or putting on music, many of us have some kind of ritual – small or large – that we do to "wind down" in bed. But it can be hard to gauge how good or bad these activities are. Now for one popular pastime, we know more.

A new study has ranked the best types of exercise for improving sleep quality. The findings demonstrate that exercise is an easy-to-implement, relatively cheap, and particularly effective way of treating insomnia, a common problem for older adults.

In an analysis of the sleep habits of over 72,000 people, researchers identified a particular pattern that can dramatically spike the risk of major cardiovascular problems. The good news is that the pattern is relatively easy to avoid.

One of the best things about sleeping on a train is the gentle rocking motion that lulls you off to la-la land. Well, the Ensven 3 Modular Bed Rocker brings that same motion to people's beds, with a lot more oomph than its predecessors.

New York might be known as the city that never sleeps, but it turns out there's a lot less shuteye happening in smaller urban areas across the globe. And it's not because of nightlife, but artificial light emitted from buildings and infrastructure.

For the first time, there's scientific evidence that a smaller, lesser known component of cannabis – cannabinol – delivers better quality and longer sleep. It proved to be comparable to existing sleep aids, without the undesirable side effects.

Melatonin is already a popular supplement for those who struggle to get a solid night's sleep. But the dosage of the supplement and the best time to take it has remained largely a trial-and-error endeavor. A new study puts that uncertainty to bed.

Toxic “forever chemicals” are a major environmental problem, and a growing body of research shows they’re also a major health problem. A new study has found people with higher levels of PFAS in their blood have poorer sleep.
