TV sets, laptops, iPads and iPhones are modern society's instruments for increased productivity, social connectedness and entertainment after a long day's work. Ironically, a new study published in Molecular Psychiatry shows that these devices also contribute to an increase of major depressive disorder. The 24-hour society made possible by the advent of the electric light bulb has come at a significant biological cost. Light at night disrupts the body's natural circadian rhythms and has been linked to breast cancer, heart disease and obesity.

Levine was transferred to the northern Alaska outpost at Ft. Wainwright, he noticed a common complaint among his patients.

As summer winds down, another new school year brings fresh notebooks, sharp pencils and — for many kids — a new cycle of sleep deprivation. With classes that start as early as 7 a.m. and buses that pull up long before sunrise, some 80% of American kids in grades 6 through 12 are falling short of sleep recommendations during the school year, according to research by the National Sleep Foundation, a sleep advocacy group. Overtired kids, studies suggest, struggle with depression.

The human circadian rhythm, a tyrant that dominates human existence, may be reset far more easily than previously believed, according to a new study in today's issue of Science magazine. The study comes at a time of increasing research into the mysterious, periodic cycles that govern life, and such studies are yielding new knowledge that is of potential benefit to millions of people who work non-traditional hours.

Riding in school buses in the early morning, then sitting in poorly lighted classrooms are the main reasons students have trouble getting to sleep at night, according to new research. Teenagers, like everyone else, need bright lights in the morning, particularly in the blue wavelengths, to synchronize their inner, circadian rhythms with nature's cycles of day and night. If they are deprived of blue light during the morning, they go to sleep an average of six minutes later each night, until their bodies are completely out of sync with the school day, researchers from Rensselaer Polytechnic Institute reported Tuesday in the journal Neuroendocrinology Letters.

Heaven in a jar, my friend Carla calls it. Walking toward the skin-care counter, I wonder what's in the baby-blue cream she swears makes her feel as if she's had a "mini-face lift." The lavender-scented cream, the sales rep says, is made from a "patented copper peptide complex" used on burn victims' ravaged skin and diabetics' slow-healing wounds. If it can stimulate the production of collagen for them, he says, consider the power it could unleash on aging skin--a casualty of collagen breakdown.

When the occasional night spent walking the floor with a crying baby or rocking a toddler becomes a common occurrence, pediatricians often advise a little pharmaceutical help. A survey of 671 mostly suburban pediatricians showed that 75% had recommended sleeping medication for a child within the last six months. But few studies have examined the effectiveness of sleeping medicines in children, and no medication has been approved for them by the Food and Drug Administration.

For some people who suffer from insomnia, traditional treatments such as behavior therapy and prescription drugs produce undesirable side effects or don't work. This makes folk remedies and alternative health treatments for insomnia very popular. But do they work?
