Delta wave activity disruption during sleep may be a useful metric to identify those at an increased risk for cardiovascular disease and cardiovascular mortality. An international team of researchers ...

This sleep short is designed to help you fall asleep faster, reduce stress, and improve the quality of your sleep. Perfect ...

Deep sleep is one of the most essential stages of the sleep cycle, playing a vital role in how well you feel both physically and mentally. Often referred to as slow-wave sleep or delta sleep, this ...

Scientists pinpoint the molecular epicenter of deep-sleep regulation. The findings, based on research in mice, identify a gene that makes a protein that regulates delta waves -- electrical signals ...

A new study has uncovered the mechanism by which the brain waves produced during deep sleep can predict blood glucose control. The discovery not only highlights the importance of sleep in managing ...

"I have to get my deep REM sleep," expresses a common confusion about two very different types of sleep. Deep sleep and rapid eye movement (REM) sleep are not the same; they do not even overlap. They ...

Researchers have uncovered a potential mechanism in humans that explains how and why deep-sleep brain waves at night are able to regulate the body's sensitivity to insulin, which in turn improves ...
