It's a universal truth: When you're in your 20s, you can stay out all night and look fresh the next morning. Unfortunately, as we age, lack of sleep affects us more deeply and shows more prominently on our faces -- lackluster complexions, dark circles, fine lines and, in more extreme cases, rashes and eczema. Progressive loss of cellular water may be one reason sleepless nights affect our skin more visibly as we age, says board-certified dermatologist Dr. Howard Murad. Water retention is key to keeping skin moisturized and supple, which can translate to fewer lines and a smoother complexion.

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.

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 disease 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?

Health and fitness products can make great holiday gifts. A thoughtfully chosen natural remedy or exercise device sends all of the right messages: I care about you, I want you to feel your best and I don't want to risk guessing wrong about your sweater size. But if you give a health product that doesn't live up to its claims, you end up sending a different message: I didn't do my homework, sorry for the disappointment and, hey, better luck next year. In an annual tradition, the Healthy Skeptic has gathered several items that could conceivably end up on a gift list.
