“Falling asleep does take about 15 minutes for the healthy sleeper,” Robbins added. “Falling asleep is distinct from sleep itself, which can be frustrating when one is extremely tired.
“Nevertheless, be patient that sleep will come and the more you stress about not being asleep, the lower your chances of falling asleep,” she said.
Dozing off too quickly could be a sign that you are seriously sleep deprived, which can harm your physical and mental health.
Robbins, who coauthored the book “Sleep for Success!,” equates it to having been deprived of food. “If you are starved for food, you will devour your next meal immediately, whereas a well-nourished person might not be as ravenous and in dire need of nutrition immediately,” she said.
What if you do sleep an adequate number of hours each night? Then falling asleep too quickly, as well as being tired during the day, could be a sign that the quality of your sleep is suffering.
“A lack of quality sleep occurs when there are multiple awakenings and arousal during the night,” said Dr. Raj Dasgupta, an assistant professor of clinical medicine at the Keck School of Medicine at the University of Southern California, who specializes in sleep.
“Those awakenings affect your ability to get to the deeper stages of sleep, such as slow wave sleep, also known as delta sleep, or rapid eye movement (REM) sleep, which are both essential if you want to function well and be alert,” Dasgupta said.
Slow wave or delta sleep is when the brain both rests and gets rid of toxins — a form of housekeeping that allows the body to heal and rejuvenate.
“The take home message is that if you’re not getting quality sleep, that means its time to see a sleep specialist to see what’s going on,” Dasgupta said.
How to fall asleep faster
Now that your expectations are realistic — it’s not healthy to go out like a light, and you shouldn’t worry if you need 10 to 20 minutes to fall asleep — what about those nights when sleep is overly elusive?
Get up! “If you can’t fall asleep after 20 minutes, get out of bed and go into another room where there is dim light, and do something calming until you feel drowsy again. The same applies when you wake in the night and can’t fall back asleep,” Dasgupta advises.
Robbins agrees: “Promise to never toss and turn — commit to leaving your bed if, for whatever reason, you toss and turn at night and experience difficulty falling asleep.”
Some people believe that it’s just as refreshing to your body to lie in bed with eyes closed but not sleeping. That’s just a pipe dream, Robbins said: “If we stay in bed, we’ll start to associate the bed with insomnia.”
Keep the bed sacred. Keeping your brain from seeing the bedroom as anything other than a place to sleep and have sex is how you train it to fall asleep when your head hits the pillow, Dasgupta said.
“You’re much more likely to drift off quickly if your brain knows exactly what to expect when you enter the bedroom,” he said.
That means don’t work or watch television in bed, and don’t make calls or check your cellphone. Blue lights from electronic devices tell our brains to wake up, not sleep.
Build a nest. Keep training your brain to expect sleep by nurturing the sleep process. Keep the room cool and dark. Science tells us that we sleep better in cooler temperatures of about 60 to 67 degrees Fahrenheit (15 to 20 degrees Celsius).
Ready a routine. Brush your teeth, take a relaxing warm bath or shower and then spend some time in dim light reading a book or listening to soothing music. You can try yoga or light stretches, but nothing that will rev you up. You’re teaching your brain to wind down.
Calm your whirling mind. For many people, this is the hardest part of falling asleep. In today’s frantic world packed with stress and anxiety, it can be hard to stop fretting over what you didn’t do or what you need to do next.
Practicing meditation is one evidence-based way to improve your ability to fall asleep, Robbins said.
“Meditation is the act of allowing thoughts to pass without devoting conscious attention to them,” she said. “This skill, when practiced over time, can translate to our ability to fall asleep when we adopt a meditative mindset.”
Keep a “worry list” by your bedside. Another way to calm your mind is to keep a stack of notecards by your bedside and use them to document your worries.
“Start a ritual of writing down anything on your mind before bed,” Robbins said. “No matter how stressful, small, large, put it down onto one of the notecards. Tell yourself there is nothing you can do about those tasks at night, leave them for the morning.”
Breathe deeply. “Deep long breaths matched with a mantra like ‘let go’ or ‘I am at peace’ can help you calm a busy mind and slip off into sleep,” Robbins said.
Take a deep breath to a slow count of six, making sure that you can feel your stomach rise with your hand as it fills with air, explained Ackrill, an editor for Contentment magazine, which is produced by the American Institute of Stress.
“You want to use what is called soft belly breathing,” she said. “To soften your belly, let the diaphragm descend, push out on your belly a little bit and bring the breath down into that part.”
Release your breath to the same slow count of six. Pause and begin again. Repeat until you feel your body relax, Ackrill added.
Don’t stop dreaming. Keep up these habits and before long your brain will automatically know that pillow equals sleep. Then maybe that dream of falling asleep more quickly will come true after all — the healthy way.
