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.

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.

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 diseaseĀ  and obesity.

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? Here is what some experts say: Warm milk: Milk contains the amino acid tryptophan, which is touted to alleviate stress and produce serotonin, a brain chemical that helps control sleep.

The links between sleep and cancer are now so many, you could build a chain. A new study has found that for men who suffer insomnia and unwelcome wakefulness, the risk of prostate cancer is greater than for those whose sleep is undisrupted. That research expands on a growing body of evidence that men and women whose sleep is short, broken or of poor quality are at higher risk of developing a wide range of cancers. Research has long linked overnight shift work -- and the circadian rhythm disruptions that are common with it -- as a risk factor for breast cancer and endometrial cancers in women.

Lloyd Leavitt shrugs off the subzero freeze that blankets the Arctic town of Barrow each winter. It's the weeks of endless night that get to him, filling him with insatiable cravings for carbs, sleep and natural light. "There comes a time when you don't know if it's morning or evening. You get confused," said Leavitt, who has lived all his 49 years in the nation's highest-latitude community. Leavitt has plenty of company when it comes to dealing with Alaska's dark side.
