How to Fall Asleep Fast

Develop a “power down” ritual before bed. The light from computer screens, televisions, and phones can hinder the production of melatonin, which means your body isn't preparing the hormones it needs to enter the sleep phase. Specifically, it is the blue wavelength of light that seems to decrease melatonin production. Developing a “power down” routine where you shut off all electronics an hour or two before sleep can be a big help. Additionally, working late at night can keep your mind racing and your stress levels high, which also prevents the body from calming down for sleep. Turn off the screens and read a book instead. It's the perfect way to learn something useful and power down before bed. (Another option is to download an app called f.lux, which reduces the brightness of your screen closer to bedtime.)

Use relaxation techniques. Researchers believe that at least 50 percent of insomnia cases are emotion or stress related. Find outlets to reduce your stress and you'll often find that better sleep comes as a result. Proven methods include daily journaling, deep breathing exercises, meditation, exercise, and keeping a gratitude journal (write down something you are thankful for each day).

How to Improve Sleep Quality and Duration

If you want to know how to sleep better and boost your performance there are 3 levers you can “pull” to give yourself a boost.

• Intensity
• Timing
• Duration

Intensity refers to how well you sleep. The percentage of sleeping time you spend in slow wave sleep and REM sleep largely determine the quality of your sleep each night.

Timing refers to when you go to sleep. What time do you go to bed? This factor is important for two reasons. First, if you get in bed around the same time each night, it is easier for your body to develop good sleep habits. Second, the time you go to sleep should be in accordance with your circadian rhythm.

Duration refers to how long you sleep. This one is simple: how much time do you spend sleeping each night?

How can you use these 3 levers to sleep better?

When it comes to intensity, the truth is that there isn’t much you can do. Your body largely manages the intensity of your sleep cycle (how much time you spend in slow wave sleep and REM sleep) for you. It adjusts automatically based on what you need and how much time you are spending asleep. Exercising consistently, being smart about light habits, and getting proper nutrition will help, but these actions only indirectly improve sleep intensity.

This is actually good news because it simplifies things for you. Because your body manages the quality of your sleep on its own, you only need to focus on two factors: timing (when you go to bed) and duration (how long you're in bed).

If we make another assumption, then we can simplify the situation even further. That assumption is this: You wake up at approximately the same time each day.

If you wake up at about the same time each day, then your sleep duration is basically determined by when you go to bed. Generally speaking, if you get into bed earlier, then you'll end up sleeping more. Improve the timing and you'll improve the duration as well.

And that brings us to this practical punchline…

From a practical application standpoint, timing is perhaps the most important of the 3 levers of sleep. The intensity of your sleep is managed automatically by your body. The duration of your sleep is largely dependent on when you get into bed (assuming you wake up around the same time each morning). And that means getting to bed at an earlier, more consistent time is critical for improving the quality and duration of your sleep.

Daily Habits for Better Sleep

Next, let's talk about how to sleep better by harnessing the power of a few simple, daily habits.

Get outside. Aim for at least 30 minutes of sun exposure each day.

Turn out the lights. When it gets dark outside, dim the lights in your house and reduce blue or full-spectrum light in your environment. F.lux, a free software app for your computer, makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

Avoid caffeine. If you're having trouble falling asleep, eliminating caffeine from your diet is a quick win. If you can't go without your morning cup of coffee, then a good rule of thumb to keep in mind is “No coffee after noon.” This gives caffeine enough time to wear off before bed time.

Stop smoking or chewing tobacco. Tobacco use has been linked to a long line of health issues, and poor sleep is another one on the list. I don't have any personal experience with tobacco use, but I have heard from friends who have quit successfully that Allen Carr's Easy Way to Stop Smoking book is the best resource on the topic.

Use the bedroom for sleep and sex only. Is your bedroom designed to promote good sleep? The ideal sleeping environment is dark, cool, and quiet. Don't make your bedroom a multi-purpose room. Eliminate TVs, laptops, electronics, and clutter. These are simple ways to improve the choice architecture of your bedroom, so that sleep is easier and distraction is harder. When you go to the bedroom, go there to sleep.
