"You might think you&amp;#039;re off the clock when it comes to your beauty routine while you sleep, but your slumber hours play an important role in how you look. &amp;quot;Beauty sleep is essential for repairing the skin,&amp;quot; says Dr. Debra Jaliman, a New York City dermatologist and author of Skin Rules. If you want your skin and hair to look younger and healthier during the day, it&amp;#039;s time to adopt these nighttime habits. 1. Sleep on a satin or silk pillowcase.  These fibers will keep you from waking up with a bird&amp;#039;s nest on top of your head, and their texture softens wrinkles and fine lines because it causes less friction between your skin and the pillowcase. &amp;quot;Silk is easier on hair \u2014 it helps avoid tangles and breakage,&amp;quot; says Jesleen Ahluwalia, M.D., a physician from Spring Street Dermatology in New York City. &amp;quot;It&amp;#039;s also better for the skin because the material glides easily and prevents creasing and wrinkles.&amp;quot;  RELATED: 10 Ways to Fake 8 Hours of Sleep 2. Sleep on your back. Speaking of wrinkles, sleeping on your back can help nip them in the bud before they even start to form. &amp;quot;Repeated pressure on the skin, causing creasing, can eventually lead to set-in lines,&amp;quot; says Ahluwalia. &amp;quot;A person who sleeps on one side may even have more set-in wrinkles on that particular side compared to the other.&amp;quot; If you tend to have puffy eyes in the morning, try sleeping with an extra pillow. &amp;quot;When you lie flat, fluid can gather around your eyes,&amp;quot; Elizabeth Tanzi, M.D., a dermatologist in Washington, D.C., told Good Housekeeping. 3. Moisturize, moisturize, moisturize. For a fresh, dewy look in the morning, make sure to use an anti-aging night cream that contains hyaluronic acid. It attracts water into the skin, which helps smooth wrinkles, Francesca Fusco, M.D., a New York City dermatologist, told Good Housekeeping. Dr. Jaliman recommends always applying lip balm before sleep, moisturizing your eyelashes with a lash conditioner, and never skipping your nightly beauty cream or serum. These products work better during the &amp;quot;repair cycle of the skin,&amp;quot; which is at night, she says. RELATED: Get Better Skin While You Sleep 4. Change your pillowcases often. &amp;quot;Wash your pillowcases frequently, so you&amp;#039;re not resting your lovely skin on top of bacteria nests for eight hours a night,&amp;quot; advises Chicago makeup artist Alle Connell. Dr. Ahluwalia says you should not only change your pillowcases twice a week, but flip your pillows over on days you&amp;#039;re not changing them. 5. Sleep with a humidifier on. You probably already know that drinking tons of water is good for your skin \u2014 but since you can&amp;#039;t do that in your sleep (you&amp;#039;d have to be really talented), try using a humidifier to keep yourself hydrated at night. This is especially helpful during the winter, when your skin tends to be much drier.  6. Stay away from super-salty foods and booze around bedtime. &amp;quot;When you consume a lot of alcohol, your body becomes dehydrated,&amp;quot; says Dr. Fusco. &amp;quot;To compensate, it starts collecting natural fluids around the eyes, among other places.&amp;quot; A similar thing happens with salt, leading to that dreaded puffy-eye look. If you indulged in some chips and a glass of Chardonnay anyway, try the above extra-pillow trick to help drain fluids.  RELATED: Is Your Makeup Aging You? 7. Wear your hair up \u2014 but not in a super-tight bun. It&amp;#039;s a good idea to keep your hair out of your face while you&amp;#039;re sleeping to keep its natural oils from wreaking havoc on your complexion. But avoid pulling it into a really tight bun or ponytail because that can cause hair breakage, especially around the hairline. Connell suggests wrapping it up in a scarf (silk would be ideal), while Dr. Ahluwalia says that high, loose ponytail is a great way to keep your most recent blowout intact. 8. Go to bed with a clean face. &amp;quot;So many people sleep with their makeup on and wonder why they wake up with funky eye gunk in the morning,&amp;quot; Emily Kate Warren, a New York City makeup artist, told Good Housekeeping. &amp;quot;That&amp;#039;s why.&amp;quot; Aside from funky eye gunk, not taking off your makeup before sleep causes pore-clogging, which can lead to breakouts.
