Whole grain crackers. It’s not just a coincidence that you immediately want to take a nap after chowing down on a carb-heavy meal. Carbs cause your body’s blood sugar levels to spike, which appears to play a role in regulating your body’s sleep-wake clock, suggests a recent Japanese study. Still, you’ll probably get a stomachache and end up tossing and turning all night—by devouring a gigantic bowl of pasta. So pick a lighter option, like a handful whole grain crackers.
The federal government’s Healthy People initiative has established a goal of getting more people to get adequate sleep on a regular basis. Their recommended amount of sleep is 8 hours for people 18 to 21 and 7 hours per night for adults over 21. According to their numbers, 69.6% of the population meets this goal, and the government wants to raise this to 70.9% by 2020.
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.”
LabDoor gave Source Naturals’ melatonin high marks for label accuracy, with a score of 82.3 out of 100. Note that this score is for Source Naturals Melatonin 1 mg Orange Flavor, which offers a very strong burst of citrus (though no medicinal taste at all). If you’re not a fan of citrus, we’d suggest Source Naturals’ unflavored melatonin instead — or you can try the peppermint formula. At $0.06 per serving, any one of these flavors represents an affordable option.
Sleep medications, which are most useful for short-term sleeplessness, do require some caution, because they can result in hangovers the next day, or, even worse, lead you to eat, amble about, and even drive while asleep, with no memory of having eaten, ambled about, or driven. The FDA suggests that if you take Ambien, in particular, and at certain dosages, you shouldn’t drive the next day, or take part in other activities that necessitate your being completely awake, because the drug can remain in your system at levels that may affect your functioning.
Circadian rhythms direct a wide variety of functions from daily fluctuations in wakefulness to body temperature, metabolism, and the release of hormones.  They control your timing of sleep and cause you to be sleepy at night and your tendency to wake in the morning without an alarm.  Your body’s biological clock, which is based on a roughly 24-hour day, controls most circadian rhythms.  Circadian rhythms synchronize with environmental cues (light, temperature) about the actual time of day, but they continue even in the absence of cues. 
After talking with doctors and examining clinical studies, we learned that the research surrounding common remedies for restless nights, like melatonin and valerian, is often contradictory. To find the best sleep aid, it’s important to look for an active ingredient that suits your particular sleep problems — and to pay close attention to your dosage and timing.

 The brain stem, at the base of the brain, communicates with the hypothalamus to control the transitions between wake and sleep.  (The brain stem includes structures called the pons, medulla, and midbrain.)  Sleep-promoting cells within the hypothalamus and the brain stem produce a brain chemical called GABA, which acts to reduce the activity of arousal centers in the hypothalamus and the brain stem.  The brain stem (especially the pons and medulla) also plays a special role in REM sleep; it sends signals to relax muscles essential for body posture and limb movements, so that we don’t act out our dreams.
Adjustable beds also allow you to change the angle of your upper body and legs. This can be particularly helpful for people who experience conditions like lower back pain or swelling, since these adjustments can reduce back tension and promote circulation to improve comfort. Acid reflux keeps many people up as well, and elevating the upper body can make a significant difference.
LIGHT: The other thing is no blue light close to bedtime. There are a lot of studies that screen time close to bed is bad. One of the ideal ways of using our app is to connect it to your Bluetooth speakers so that you can put your phone in another room: There is something important to not having your phone in reach, because then you’re looking at the screen and getting the brightness. If you live in the city and there’s bright lights at night, having blackout shade can also be super useful.

You can practice mantram anywhere, especially as a sleep aid and a natural remedy for insomnia- it is a totally portable technique, requires no training or equipment, and can be used in any circumstance, so long as you don’t practice it while doing something that otherwise requires your undivided attention. Try experimenting with it – choose a word, sound or phrase that is pleasing to you, and repeat it. If your mind wanders, simply focus back on the word. You will be amazed at the results.

How glycine helps sleep: Glycine can improve symptoms of insomnia, and can help you bounce back to healthy sleep cycles after a period of disrupted sleep. A recent study of the effects of glycine as a supplement showed it triggered a drop in body temperature and at the same time helped people both fall asleep more quickly and spend more time in REM sleep. And glycine may help you move more quickly into deep, slow wave sleep. 
There are diagnostic tests that can be helpful for assessing your sleep problems, with special tests for insomnia. It may be helpful to keep a sleep log or use an actigraph (like a fitness tracker) to track your sleep patterns. Further testing with an overnight sleep study called a polysomnogram can also be helpful to identify sleep apnea or restless legs syndrome as potential contributors to insomnia.
If you try just one sleep hack, make it this one. Junk light — the blue light that emits from your smartphone, laptop, and tablet screens — is wrecking your sleep. Too much blue light messes with your brain’s production of melatonin — the hormone that tells your body when it’s time to snooze. Blue light wakes you up and tells your brain that it’s daytime. Screens aren’t the only source of junk light — street lamps and LED lightbulbs are also to blame.
4. Sleep in a familiar, dark, and quiet room that is adequately ventilated and neither too hot nor too cold. If possible, try to use this room for sleeping only, so that you come to associate it with sleep. In time, your room could become another sleeping cue. If your sleeping environment is sub-optimal, try to use aids such as earplugs or a sleeping mask.
