(CNN)If you feel wide awake when your head hits the pillow at night, you're not alone. Approximately 60 million Americans report having experienced insomnia in any given year, according to the National Institute of Neurological Disorders and Stroke. Even worse, 40 million Americans suffer from long-term sleep disorders.
9 ways to fall asleep faster
Missing sleep is nothing to yawn about. "Chronic sleep deprivation has lots of negative consequences," says Sonia Ancoli-Israel, fellow of the American Academy of Sleep Medicine and Professor of Psychiatry at the University of California San Diego School of Medicine. She notes that the health risks associated with missed zzz's can include poor cognitive function, problems with attention and concentration, dementia and an increased risk of heart disease.
Why every night of sleep matters
Are you getting enough shut-eye? Most adults need seven to eight hours of sleep a night, according to Dr. Ancoli-Israel. "People are so busy in their everyday lives and something has to give. They give up on sleep rather than something else," she says.
Even if you don't suffer from insomnia, odds are you've experienced nights when you've tossed and turned, wondering why you can't drift off. "Everyone has a bad night now and then," says Dr. Ancoli-Israel. But if you get tense and worried about not being able to sleep, your frustrated mindset could make it even harder to relax into slumber the following nights.
The consequences of missing even a few hours of sleep can be serious. Research shows that short-term sleep deprivation can cause you to crave high carbohydrate and high sugar foods. It can even make it harder to choose healthy options when grocery shopping. Plus, one sobering study revealed that drowsy drivers who had been awake for 18 hours were just as impaired as drivers who had been drinking.
Fortunately, there are steps you can take to help ensure you'll actually pass out once your head hits the pillow.
If you're moving at full-speed all day, it can be tough to suddenly switch yourself "off" at night. "We are assaulted by information all the time and it's really up to us to create routines that help separate the buzzing of the brain from our sleep routines," says Janet Kennedy, Ph.D., clinical psychologist, founder of NYC Sleep Doctor and author of The Good Sleeper: The Essential Guide to Sleep for Your Baby (and You). She recommends giving your mind and body a full hour to wind down from work (or happy hour) before you try to fall asleep.
Spending time in a steamy shower could be beneficial even if you don't need to rinse off. Dr. Kennedy points out that your body temperature drops rapidly once you exit the shower. Research shows that this decrease in temperature can trigger a sleepy feeling because your heart rate, digestion and other metabolic processes slow down. This can make it easier for your brain and body to power down, too.
Showering isn't the only trick in the book. When it comes to optimizing your temperature for sleep, the ideal balance is a cooler core and warmer extremities, says Professor Ancoli-Israel. One study revealed that wearing socks dilates your blood vessels and can help blood flow, leading to a more optimal temperature for snoozing.
We've all been there: No matter how many times you flip over, you just can't seem to find that sweet spot that will let you slip into slumber. But instead of trying to find the perfect position, concentrate on finding the perfect way to breathe.
By deliberately changing the pattern of your inhales and exhales, you can change your heart rate and blood pressure, two systems linked to sleepiness. Many relaxation specialists recommend inhaling through your nose, focusing on filling your chest and lungs (for about three to four seconds) and then exhaling slowly through your mouth for double the time you were inhaling. Another method, known as the "4-7-8 exercise," involves inhaling for four seconds, holding your breath for seven seconds, and exhaling for eight seconds.
Trying to score some extra zzz's by going to bed at 8 p.m. is a recipe for disaster. "If you aren't sleepy, your body won't settle down," says Dr. Kennedy. And according to Professor Ancoli-Israel, your sleep will actually be worse the longer you stay in bed. "Eight hours of sleep is more efficient than nine to 10 hours in bed," she says.
Relaxation techniques like visualization or progressive muscle relaxation can help you unwind. But don't wait until it's dark outside to try these for the first time. "You don't want to do it the first time when you're anxious," Dr. Kennedy says. "You want to start really getting the skill down when it's easy for you, then try it in more difficult situations." If you're using an app to guide you, try to practice until you don't have to bring your device into the bedroom with you (because that can mess up sleep, too).

Lying in bed and worrying about your inability to fall asleep will not help. "The second you start feeling tense, go into another room until you start feeling sleepy," says Professor Ancoli-Israel. You want to condition your brain to associate the bed with sleeping and nothing else, she explains.
Feeling frustrated "creates a stress response where the body creates adrenaline," says Dr. Kennedy. To combat this harmful feedback loop, divert your attention by reading, doing crossword puzzles, knitting, drinking tea, folding laundry or organizing closets until you start to feel drowsy. "It doesn't matter, as long as it is relaxing to you," she says.
Repeat after us: "I must stop staring at my clock." You could be waking yourself up even more, says Professor Ancoli-Israel. When you're constantly checking the time, you're putting pressure on yourself and creating a more stressful environment. Plus, Dr. Kennedy points out that your phone can suck you back into daytime stressors with every text, email or app notification. If you need to use your alarm clock or phone to ensure you rise on time, put it under the bed or in a drawer so you aren't tempted to glance at it every five minutes.
If racing thoughts keep you up, consider jotting down what's on your mind before you head to bed. Processing your feelings (good and bad!) can help you relax into a sleepier state of mind. "When you're thinking through that stuff and you're laying down, it can become circular," says Dr. Kennedy.
By writing things down or making a list of tomorrow's to-dos, you'll tame any bouncing thoughts and turn them into a more linear narrative. Instead of endlessly worrying about the next day's workload, you'll have already plotted out how you'll get everything accomplished before you hit the hay.
