Field study demonstrates that extended daylight hours influence teens' sleeping patterns.
Blue light treatments may improve sleep quality in older adults, U.S. researchers found.
Sleep disturbances increase as we age. Some studies report more than half of seniors 65 years of age or older suffer from chronic sleep disturbances.
Like a wristwatch that needs to be wound daily for accurate time-telling, the human circadian system â€” the biological cycles that repeat approximately every 24 hours â€” requires daily light exposure to the eyeâ€™s retina to remain synchronized with the solar day. In a new study published in the June issue of Neuroscience Letters, researchers have demonstrated that when it comes to the circadian system, not all light exposure is created equal.
Tired travelers may have a means of reducing or preventing jet lag, researchers report.
A simple, at-home treatment -- a single light box and the over-the-counter drug melatonin -- allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones, according to new research being published in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism. This treatment can also help those with delayed sleep phase syndrome (DSPS), a persistent condition that results from a misalignment between a person's internal biological...
