Probably the most common wearable to measuring sleep right now is the Fitbit. I’ve studied these devices in depth in a well-controlled laboratory experiment where we’re monitoring brainwaves. I can say the Fitbit is pretty accurate in measuring when you’re asleep and when you’re wake, but when it comes to measuring sleep stages, basically any device that measures heart rate, like the Apple Watch, is totally inaccurate. That’s because they don’t sample at the frequency necessary to get a good read on your sleep stages.

When you eat and what you eat can significantly impact the quality of your sleep. While you don’t want to go to bed feeling hungry because low blood sugar can interrupt your sleep, it’s also not beneficial to eat right before you hit the sheets. Therefore, it’s best to eat 2-4 hours before going to bed. There are certain foods consumed during this window that can be beneficial for sleep, while other types of foods can hinder your slumber.
According to the American Sleep Association, one in every three adults experiences occasional insomnia, while another one in 10 has chronic insomnia. While most of us crave a good night’s sleep for the short-term benefit of feeling more alert, we also realize that sleep is crucial to our health. During those nightly hours of shut-eye, our bodies experience a prolonged period of repair and renewal that can improve everything from treatment of chronic conditions to weight management.
Probably not all people will be able to fall asleep this quickly all the time, especially on days when you might be upset or anxious near bedtime for whatever reason. Your best bet is not to try just one or two strategies from the article, but as many of the strategies as you can at the same time, and keep up this routine for several weeks or more.
Are you ready to start sleeping better? Read on to find out why sleep matters, how much sleep you really need, and science-backed sleep hacks to improve your sleep. As Bulletproof Founder Dave Asprey writes in his new book “Game Changers: What Leaders, Innovators, and Mavericks Do to Win at Life”, “sleep quality drives happiness, and as we’ve seen, happiness drives success.”
Challenge yourself to stay awake – your mind will rebel! It’s called the sleep paradox, says psychotherapist Julie Hirst (worklifebalancecentre.org). She explains: “Keep your eyes wide open, repeat to yourself ‘I will not sleep’. The brain doesn’t process negatives well, so interprets this as an instruction to sleep and eye muscles tire quickly as sleep creeps up.”
Research published earlier this year in the journal Scientific Reports found that listening to sounds from nature, like a rainforest soundscape or a babbling brook, can trigger a relaxation response in the brain. Soothing background sounds can also cover up manmade sounds like voices or traffic, which were shown in the study to have the opposite effect.
Spicy foods. Can’t get enough sriracha? Save it for lunchtime. One International Journal of Psychophysiology study found that when people who consumed hot condiments (like Tabasco sauce or mustard) before bed took longer to fall asleep and achieved less restful sleep compared to when they skip the stuff. Researchers aren’t totally sure why spicy foods mess with your sleep, but it could be because they raise your body temperature.
So if you're unable to sleep for about a 15- or 20-minute stretch, slip into your bunny slippers and out of the room. Try something relaxing and non-stimulating. Listen to music. Read a book. Even consider cleaning the house or doing the dishes, Olson suggests. A bath might do the trick, according to the National Heart, Lung, and Blood Institute, because sleepiness can brew from the post-bath drop in body temperature. Whatever activity you choose, do it away from bed, and return when you're feeling drowsy.
Alcohol may initially sedate you, making it easier to fall asleep; however, as it is metabolized and cleared from your system during sleep, it causes arousals that can last as long as two to three hours after it has been eliminated. These arousals disturb sleep, often causing intense dreaming, sweating, and headache. Smoking while drinking caffeine and alcohol can interact to affect your sleep dramatically. These sleep disturbances may be most apparent upon awakening, feeling unrefreshed, groggy, or hungover.
If you often find yourself having trouble falling sleep, you’re not alone. The American Sleep Association (ASA) says that 50 million to 70 million U.S. adults have a sleep disorder. Among that group, insomnia is the most common. The ASA says that 30% of adults have reported short-term, insomnia-like symptoms, and 10% of American adults deal with chronic insomnia.
Millions of people are using smartphone apps, bedside monitors, and wearable items (including bracelets, smart watches, and headbands) to informally collect and analyze data about their sleep. Smart technology can record sounds and movement during sleep, journal hours slept, and monitor heart beat and respiration. Using a companion app, data from some devices can be synced to a smartphone or tablet, or uploaded to a PC. Other apps and devices make white noise, produce light that stimulates melatonin production, and use gentle vibrations to help us sleep and wake.
Use a blue light filter on your device. The blue light emitted by smartphones and tablets can be a powerful sleep disruptor. It suppresses your body’s production of melatonin and throws your circadian rhythm off, making it harder to fall and stay asleep. Luckily, many smartphones these days have a “night shift” feature that adjusts the screen from cool (blue) to warm (yellow) light, which is less likely to keep you up past your bedtime. Likewise, there are apps you can run on your laptop or tablet that reduce blue light. Some popular ones are f.lux and Twilight.
