This Is What's Ruining The World's Sleep -- And It's Not Our Technology Addiction

Between keeping our smartphones by our pillows and binge-watching Netflix before finally closing our eyes, you'd think our ever-growing connection to technology was responsible for most of our sleep woes. But it turns out stressing about money and work takes the sleep deprivation-causing cake, according to a new survey.

In recognition of World Sleep Day and with the help of research firm KJT Group, Philips conducted a survey titled "Sleep: A Global Perspective" to help gain insight into the main sleep disturbances affecting people worldwide. They found that worrisome thoughts about work and economic or financial issues are the top two stressors keeping people awake at night. Speaking with almost 8,000 people across 10 countries, the research team gathered information regarding participants' sleep times, wake times, daily routines, sleeping environments and perceptions of their work-life balance to determine the greatest obstacles in the way of developing healthier sleep habits.

There is no question whether people believe sleep is important. Ninety-six percent of respondents said sleep is valuable to them, and sleep proved the most valuable of the 12 measured factors influencing a person's overall health and well-being. However, money and financial security ranked a close second, and 28 percent said economic and financial stress was their most common sleep disrupter, followed by work stress at 25 percent.

"Our report indicates how psychological factors can impact sleep, and how those factors can change depending on the times in which we live," Mark Aloia, Ph.D., the senior director of global clinical research for Philips, said in a statement. "Combating stress is critical to a good night's sleep, but the toughest part for people is often just getting motivated to make changes."

Speaking of changes (or lack thereof), 57 percent of participants said that while the quality of their sleep could be better, they haven't taken any measures to improve it. This gap between diagnosing a problem and implementing and maintaining steps to solve it is where much of the world falls short on healthful habits in general.

"There are a lot of things that feed into inaction in terms of healthy living," Aloia told The Huffington Post. "There's the individual, psychological component -- the feeling that my life isn't bad enough to need dramatic change -- and implementing and maintaining those changes is hard. And there's the societal component -- we wear lack of sleep like a badge, and as long as we do that as a society, we are going to make it very hard to take action at a societal level."

When it comes to sleep efficiency specifically, Aloia says employers must take the lead in allowing their employees to value their health in order to help minimize the current conflict between sleep needs and existing stress. The resulting healthy workforce isn't just helpful for the employees individually -- it's better for the company's bottom line.

Aloia also said that even though it didn't rank at the top of the list, we still shouldn't downplay the role that technology plays in disrupting the quality and quantity of our nightly shut-eye. According to the survey, 67 percent of people still sleep with their cell phones within reach, and 21 percent said that technology significantly disrupts their sleep.

"Technology is a facilitator of change, but it doesn't change behavior," he said. "On a personal level, we need to value technology enough to personalize it and create that change in our own lives." Instead of using distraction techniques like watching television (and even reading a book!) during our necessary decompression time at the end of the day, Aloia suggests trying mindfulness, meditation or gentle exercise, all of which provide a mental buffering of sorts and create hormonal changes in the body that help us work through sleep-disturbing stress.

  • 1 E-readers

    As if there weren’t enough things keeping you tossing and turning each night, here’s a new one: Using short-wave, blue light-emitting e-readers, like the iPad, iPhone, Nook Color, Kindle and Kindle Fire, before bedtime can make it harder to fall asleep, according to a December 2014 study at Brigham and Women’s Hospital.

    "When blue light hits the optic nerve, it tells the brain to stop producing melatonin," which is "the key that starts the engine for sleep," says Michael Breus, Ph.D., diplomate of the American Board of Sleep Medicine and fellow of the American Academy of Sleep Medicine. "This is especially problematic, since as you get older, the ability to produce melatonin becomes even more compromised."

    Fixes: Open up a real book instead. (Remember those?) If giving up your e-reader is impossible, look for screens and glasses that can block the sleep-stealing blue light on websites like Lowbluelights.com.
  • 2 Being overweight

    Carry extra pounds, especially in the neck and trunk section, and it’s more likely you’ll suffer from sleep apnea, which causes your airway to become blocked or obstructed during sleep, robbing you of quality deep sleep. The condition affects 90 percent of obese men, though it's not purely a man's disease. The Cleveland Clinic reports that after menopause, it’s just as likely to affect women. Even more disturbing, it goes undiagnosed in as many as 80 percent of those who get a lousy night’s sleep.

    "Sleep apnea can mask itself as fatigue, trouble with concentration, dry mouth or even depression," states Dr. Breus. Unfortunately, sleep apnea and obesity is a bit of a chicken-egg scenario. Do sufferers have problems because they’re obese, or is their obesity stoked by their compromised sleep? No one knows for sure, but what’s known is this: Poor sleep makes people less motivated to increase physical activity, which can lead to more weight gain. Additionally, reduced sleep is associated with elevated levels of the hormone leptin, which helps regulate appetite.

    Fixes: Among the various treatments for sleep apnea is a continuous positive airway pressure (CPAP) machine, which delivers air pressure via a mask that sits over your nose or mouth while you sleep. Other treatment options include losing weight, oral appliances (that resemble mouthguards), and Inspire Upper Airway Stimulation (USA) therapy, a new FDA-approved implantable device.
  • 3 Medications

    Many popular over-the-counter pain medications, like Excedrin and Bayer Back and Body, may contain caffeine, which helps the medication get absorbed more quickly, but can cut into your sleep, according to Dr. Breus (who suggests always checking the label first). If you’re feeling under the weather, beware of nasal decongestants and daytime cold or flu medicines, as well, which can contain pseudoephedrine; you’ll feel jittery instead of tired. Instead, The National Sleep Foundation suggests choosing a medication specifically for nighttime use, like Benadryl, NyQuil or Zyrtec, which usually contain antihistamines that promote drowsiness instead.

    Diuretics, water pills for heart disease and high blood pressure, and ADD medications like Adderall and Ritalin can also disrupt sleep, says Hrayr Attarian, M.D., a neurologist at Northwestern Memorial Hospital in Chicago, Illinois. Other culprits include steroids and some medications for depression or asthma. "As with any new medication, always check with your doctor first," says Dr. Attarian.

    Fixes: If your meds are causing sleep problems, "First, I’d suggest talking to your physician to see if your medication can be changed or the dose adjusted," says Dr. Attarian. "If that doesn’t work, you can go to a sleep clinic to discuss treatment options that may or may not include sleep aids. Taking a sleeping pill is not always the right thing right away especially if you are taking other medications to manage health conditions."
  • 4 A warm bath

    Body temperature naturally begins to drop before bedtime, preparing us for sleep. Although a warm bath can relax and calm you, taking one too close to bedtime will not give your body enough of a chance to cool sufficiently to bring on slumber.

    Fixes: To reap the full benefits of your bath, the National Sleep Foundation recommends finishing up your soak at least an hour before climbing into bed. While you’re at it, keep your room cool. "We sleep better in cool rooms," says Patrick D. Lyden, M.D., chairman of the Department of Neurology at Cedars-Sinai Medical Center in Los Angeles, California.
  • 5 Choosing the wrong foods

    If you like to snack before bed, watch what you eat. Loading up on foods that contain excessive salt or fat can stimulate brain waves, bringing on nightmares instead of sweet dreams, says the National Sleep Foundation. Choose foods that contain tryptophan (an amino acid linked to sleep quality), whole-grain carbs (which help boost serotonin production) and certain minerals (like calcium and magnesium, which can have a calming effect). Examples include half a banana and a handful of almonds, whole-grain crackers and peanut butter, a mug of warm milk, or half a turkey sandwich on whole-wheat bread.

    Fix: In general, stick to a routine of eating early in the evening and try to avoid sugar at night. "Late meals are more likely to make it harder to sleep; snacking in the middle of the night can worsen insomnia," says Andrew J. Westwood, M.D., a member of the American Academy of Neurology and American Academy of Sleep Medicine. Additionally, eating too much can make you feel physically uncomfortable when you lie down, and may cause heartburn, contributing to wakefulness.
  • 6 Clutter

    The ideal bedroom should be simply furnished and decorated, so there’s not much to distract you from the primary reason you’re in there—to sleep. Excess clutter and mess can often cause anxiety, and remind you of all your unfinished business, making it harder to fall—and remain—asleep.
  • 7 Exercise

    Sure, being physically active can make you tired, promote sleep, and improve the quality of your rest, but exercising vigorously too close to bedtime can rev you up instead. "Aerobic exercise can raise your core body temperature long after you’ve finished," says sleep specialist Rubin Naiman, Ph.D.

    Fixes: Dr. Naiman suggests completing exercise at least three hours prior to bedtime. However, gentle exercise like yoga, he says, can be helpful to promote relaxation and sleepiness.
  • 8 Stress

    When you’re stressed, your body secretes cortisol, a hormone produced by the adrenal gland. This can disrupt the body’s natural rhythm, says Dr. Naiman. "Cortisol is naturally produced in the morning. It peaks at around 8am, when it can be helpful to naturally energize us,” he explains. "But at the wrong time—like nighttime—it can make us hyper-aroused and disrupt our sleep."

    Fixes: In addition to yoga for relaxation, a new study in adults over 55 finds that practicing a popular form of meditation known as mindfulness meditation can reap improvements in sleep quality, and reduce insomnia and fatigue. Mindfulness meditation can also help reduce stress, according to a 2009 Massachusetts General Hospital study. Visit Mindful.org to learn some basics.

    If meditation is not your thing, there’s always a good old-fashioned belly laugh; laughter actually induces physical changes in your body, says the Mayo Clinic. It cools your stress response and can increase positive thoughts, which, in turn, causes your body to release neuropeptides to help fight stress.
