How Sleep Affects Your Beauty

Sleeping Beauty was onto something. Turns out, your ticket to healthier, younger-looking skin may lie between the sheets rather than on the shelf of your medicine cabinet.

While you’re fast asleep, your body is hard at work, making repairs like construction workers on the nightshift. For example, when you’re in deep sleep, human growth hormone production increases. Your normal release of this hormone plays a key role in healing cells and tissues throughout your body, including your skin.

Not getting enough sleep (and according the Centers for Disease Control and Prevention, an estimated 50-70 million U.S. adults have a sleep or wakefulness disorder) cuts that crucial repair time short, which can wreak havoc on your skin. Fine lines become more prominent, dark circles crop up and your complexion turns pale, dull and droopy.

Getting enough Vitamin Z makes you appear more attractive—sort of a reverse beer-goggles effect. In one study, people rated photographs based on attractiveness and whether the individuals in the photos looked healthy or unhealthy as well as tired or not tired. The faces of sleep-deprived participants were ranked as less healthy, less attractive and more tired compared to when they were well rested.

So how exactly does being robbed of your rest affect your appearance? “Several theories exist,” explains John Axelsson, an associate professor at the department of clinical neuroscience at the Karolinska Institutet in Stockholm, Sweden, who co-authored the study on sleep and appearance. “Sleep may actually affect the skin by reducing its capacity to recover properly, or sleep deprivation may affect muscle tone, resulting in a slightly less attractive appearance.”

THE STUDY, EXPLAINED: Sleep Boosts Beauty

When you sacrifice slumber, you decrease the ability of the skin barrier—also known as the stratum corneum, or the outer-most layer of skin—to recover from the daily damage it endures. That’s problematic because the stratum corneum plays two important roles when it comes to healthy-looking skin: It locks in moisture and prevents foreign microorganisms from getting in. Cells that make up the stratum corneum contain keratin, which is a protein that keeps skin hydrated by preventing water from evaporating.

Not getting enough sleep affects the skin barrier’s ability to do its job and can lead to dehydration, which, in turn, makes fine lines more noticeable. “Moisture helps plumps up your skin—it blows out your wrinkles,” says Robin Ashinoff, M.D., director of cosmetic dermatology at Hackensack University Medical Center in New Jersey. “Your skin droops more because you don’t have that plumpness. You’ve deflated the balloon.”

Dehydration can also trigger the classic signs of sleep deprivation—dark circles. That’s because there’s less fluid to obscure the blue blood vessels that reside just under your eyes. These blood vessels become more noticeable on the surface, showing up as dark, under-eye circles. “Overall you also look paler because the blood vessels in your face aren’t as full,” says Dr. Ashinoff. In addition to all that, “When you sleep, it’s a regenerative time, so if the skin doesn’t have a chance to turn over, you have dead skill cells sitting on top, causing the skin to look dull.”

A weakened skin barrier can leave you more vulnerable to foreign microorganisms. Think of the stratum corneum as a bouncer to an exclusive nightclub, carefully picking and choosing who gets to come in. Insufficient time in the sack makes him less discriminating about who enters the club, which is why a compromised skin barrier is associated with inflammatory skin conditions, such as atopic dermatitis, eczema and psoriasis.

Your immune system also becomes compromised when you miss out on getting enough rest. But that doesn’t just leave you more vulnerable to sickness. These changes in the immune response may affect collagen production as well. And collagen helps you maintain a youthful appearance by acting as scaffolding—holding up your skin so it doesn’t wrinkle and sag. Add to that the fact that when you’re tired, your muscles, including facial ones, are more likely to tense up, which can exacerbate your current wrinkles and bring on more fine lines and wrinkles over time.

What’s more, not getting enough z’s may bring on breakouts. “Lack of sleep correlates to physiological stress,” explains dermatologist Neal Schultz, M.D., co-author of "It’s Not Just About Wrinkles: A Park Avenue Dermatologist’s Program for Beautiful Skin—in Just Four Minutes a Day." Levels of cortisol—the stress hormone that breaks down skin cells and is linked to acne—also spike when you’re missing out on some much-needed pillow time.

BEAUTY AHA: Sleep Eight Hours to Stay Healthy and Happy

Speaking of pillows, your sleeping position can also put a crimp in your complexion. “If you sleep on your side or front, rather than your back, it’s like you’re folding over your skin—except it’s sustained pressure,” says Dr. Schultz. “It’s breaking the collagen, which can give you wrinkles and make your skin look saggy.” Sleeping on your back helps prevent fine lines from being etched into your skin overnight. But if you can’t sleep prone, try slipping on silk or satin pillowcases instead, which are more forgiving and won’t tug at your skin, causing fine lines.

The bottom-line: “Sleep is the body's natural beauty treatment,” says Axelsson. Rather than shelling out cash on expensive creams or relying heavily on concealer and coffee, try pulling a Sleeping Beauty and getting a full night’s rest instead.

5 Foods That Keep You Thin

by: LIVESTRONG.COM

Take a look around any book store, and you'll find dozens of diet books lining the shelves. Despite their bright and cheerful covers, with their positive, upbeat claims, many of them are filled with information that promotes all the wrong messages.

"The word 'diet' is negative and implies people can go on and off them," said Jane Korsberg, a senior instructor in the department of nutrition at Case Western Reserve University in Cleveland.

Korsberg is one nutritionist who thinks it would be better to re-think the whole concept of dieting.

"'Diet foods' are confusing to many people," she explained. "What diet is the 'diet food' geared for? Is it low-calorie, low-fat, low-sodium, low-sugar, gluten-free, et cetera?"

Besides, many of the foods that specifically target dieters seem to rarely satisfy. Take those 100-calorie snack packs, for example, made to help people control calories. Those often don't even work, Korsberg says. After all, few people actually stop at only one pack.

You don't need fancy plans or complicated point systems to be thin. All you need to do is make smart food choices, watch your portion sizes and stay active.

"Learning to eat properly for a lifetime is more beneficial," Korsberg said. "The emphasis should be on choosing healthful foods every day and changing lifestyles for the better."

So instead of sticking to diet fare, fill up on nutritious, wholesome foods. And if you need some recommendations, you can start with these five options, which are among the many delicious foods that make a good addition to healthy eating while keeping you slender.


Apples

Apples are a good source of dietary fiber. Dietary fiber not only contributes to a healthy digestive system and reduced cholesterol, but it also benefits smart eaters by yielding no calories while keeping them satisfied.

And there's something else about the fruit that might help you feel full. A study in the journal "Appetite" found that when women added either three apples or three pears to their daily meals, they lost more weight than people who added three oat cookies to their diets -- even though the fruit and the cookies contained the exact same amount of dietary fiber.

Although the reason behind this finding may be a mystery, there is something to be said for the findings. According to Alan Aragon, a nutritionist and author of "Girth Control: The Science of Fat Loss & Muscle Gain," crunchy foods in particular can trick a person into feeling fuller. The act of chewing may send satiety signals to your body, he says, making you think you've eaten more than you really have and keeping hunger at bay.


Almonds

If you're looking for a tasty midday snack, a handful of almonds are a well-regarded option. A study in 2009 in "The American Journal of Clinical Nutrition" found that women who ate nuts at least two times a week were more successful at keeping weight off than those who didn't eat this food.

One particular favorite among some nutritionists is almonds, says Aragon. One ounce of this food contains only 167 calories, plus it packs roughly 6 g of protein and 3 g of fiber, both nutrients that can make you feel full. Furthermore, like apples, almonds are crunchy and require a lot of chewing, so they, too, can make you feel like you've eaten more than you actually did and keep you fuller longer.


Salmon

If you're uncertain about fish, there's no need to fear. Seafood can be part of a healthy diet. And there's some evidence that the fat in foods such as salmon can boost satiety levels, says Aragon. For example, a study published in the "International Journal of Obesity" found that when dieters ate salmon a few times a week, they lost about two more pounds than those who didn't include seafood in their meals.

And in spite of the mention of salmon's fat content, the food is relatively low in calories. One 3-oz. serving has just 175 calories. Salmon is a good source of protein as well.


Eggs

There's no doubt that protein, like fiber, has impressive satiating powers. And while eggs seem to have a bad reputation in some circles, there can be no contesting their ability to help keep your weight in check.

Research has shown that eating eggs at breakfast can help you fight weight gain all day long. A study reported in 2008 in the "International Journal of Obesity" found that when dieters ate two eggs for breakfast for five days out of the week, they lost 65 percent more weight than dieters who consumed a bagel in the morning. Although protein is likely to fill you up whenever you eat it, some scientists suspect that having more in the morning can keep you feeling fuller all day long.


Tomatoes

It's true that most veggies make for great diet fare. Non-starchy vegetables in particular, such as carrots, celery and spinach, are filled with fiber. Like other foods high in fiber, they can help keep you feeling satiated.

Plus, they're pretty self-regulating, says Aragon. You can't really overeat with nonstarchy vegetables. After all, how many baby carrots can a person eat without needing to dunk them in some ranch dressing?

So while there are many veggies that can help you stay slim, tomatoes might be a particularly good option because they're so tasty. And, besides, with that whole a-tomato-is-a-vegetable-no-it's-a-fruit argument, you might have forgotten all about eating them. One cup of cooked, red tomatoes contains just 43 calories, but tastes just as delicious as any number of high-calorie foods.

And that's at least half the secret, finding foods that are both healthy and tasty. The good thing is, they do exist. Over time, you'll discover what wholesome, filling foods you prefer, expanding your choices while shrinking your waistline.
