Another common cause of difficulty falling asleep is the activities that precede your bedtime. If you eat or drink too late, you may suffer from heartburn or frequent nighttime trips to the bathroom. There are general guidelines to improve sleep. Many of these are meant to reinforce positive sleep habits. You should go to bed and get up the same time every day. Irregular sleep schedules may set you up for sleep disruption. You should follow a bedtime routine, including quiet, relaxing activities to help transition to sleep. If you fail to unwind prior to bed, you may find yourself struggling to drift off to sleep.
You’ve likely been told over and over again that a good night’s rest equals eight hours of sleep. But research shows it’s not the number of hours you sleep that matters the most – it’s the quality of the hours you are getting. The largest sleep study ever conducted on 1.1 million people shows that it’s quality, not quantity, that matters most. The researchers found that participants who slept only six and a half hours a night lived longer than those who slept eight hours. It’s easy to conclude that you’ll live longer if you sleep for six and a half hours a night, but the reality is more complicated. It’s possible that the healthiest people simply need less sleep. And when you’re getting good-quality sleep, you likely need less of it.
Everyone benefits from a good night's sleep. If you continue to have trouble sleeping, talk to your doctor. In addition to lifestyle changes, he or she might recommend behavior therapy to help you learn new sleep habits and ways to make your sleeping environment more conducive to sleep. In some cases, short-term use of prescription sleep aids might be recommended as well.
The herb Vitex agnus castus (chaste tree) may help insomnia during menstrual periods or insomnia that is a side effect of premenstrual syndrome (PMS). In one study, women with moderate to severe premenstrual syndrome were treated with either a vitex agnus castus extract or a placebo for three menstrual cycles. Participants were asked to document their symptoms with a PMS diary with a daily rating scale of 17 symptoms. They reported fewer symptoms, especially less insomnia and negative affect, but their cramps didn't improve. However, chasteberry should not be used by anyone on birth control pills, hormone replacement therapy, or dopamine-related medications, according to the National Center for Complementary and Integrative Health.
Additionally, after a thirty-hour shift without sleep, residents make a whopping 460 percent more diagnostic mistakes in the intensive care unit than when well rested after enough sleep. Throughout the course of their residency, one in five medical residents will make a sleepless-related medical error that causes significant, liable harm to a patient. One in twenty residents will kill a patient due to a lack of sleep.
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.
That doesn’t mean that you should never use medication, but it’s important to weigh the benefits against the risks. In general, sleeping pills and sleep aids are most effective when used sparingly for short-term situations, such as traveling across time zones or recovering from a medical procedure. If you choose to take sleeping pills over the long term, it is best to use them only on an infrequent, “as needed,” basis to avoid dependence and tolerance.
Stage 2 non-REM sleep is a period of light sleep before you enter deeper sleep. Your heartbeat and breathing slow, and muscles relax even further. Your body temperature drops and eye movements stop. Brain wave activity slows but is marked by brief bursts of electrical activity. You spend more of your repeated sleep cycles in stage 2 sleep than in other sleep stages.
Block out unwanted noises. Noise can impact your ability to get to sleep as well as your overall sleep quality. Try listening to a radio program or podcast that's not too engaging to help block out noise distractions such as traffic, as well as worrisome thoughts. Listen to something that is soft-spoken instead of loud, and something you enjoy but not so much that you will stay up just to listen to it. Recommended podcasts include: 
There’s this new finding where playing sounds at a certain frequency when your brain is in deep sleep actually increases the percentage of time spent in deep sleep. We’re publishing this paper in Society for Neuroscience Conference in a couple of weeks, and it’s basically what my TED talk is about. Playing these pulses at the same frequency as your deep-sleep brainwaves primes more deep sleep. Scientifically speaking, it’s a similar process as transcranial direct-current stimulation, except it doesn’t use electricity—just sound. Sound gets transmitted into electricity because you’re picking up on the auditory cortex while you’re sleeping.
You turn the light off at a reasonable hour, nestle into your pillow, and… your thoughts start going a mile-a-minute. Did you reply to that email from your boss? What should you pack the kids for lunch tomorrow? Are you living up to your potential? And why haven’t you started writing that novel/taken that trip/bought that house yet? If this sounds familiar, your stress and anxiety is getting in the way of you and some quality shut-eye. That’s where meditation comes in.
Exercising in the morning may help you sleep better than working out in the afternoon or evening. In an unpublished study presented at the 58th meeting of the American College of Sports Medicine, researchers at Appalachian State University in Boone, North Carolina, found that people spent 85 percent more time in light sleep and 75 percent more time in deep sleep when they worked out at 7 a.m. compared with working out later in the day. The authors aren’t sure why, but they believe early-bird workouts affect levels of stress hormones in a way that leads to better sleep quality later on. More research is needed to confirm these finding.
Not only does lavender smell lovely, but the aroma of this flowering herb may also relax your nerves, lower your blood pressure, and put you in a relaxed state. A 2005 study at Wesleyan University found that subjects who sniffed lavender oil for two minutes at three, 10-minute intervals before bedtime increased their amount of deep sleep and felt more vigorous in the morning.
From having occasional difficulty sleeping to insomnia, there is a lot you can do to get a better night's sleep, feel refreshed when you awake, and remain alert throughout the day. It's called "sleep hygiene" and refers to those practices, habits, and environmental factors that are critically important for sound sleep. And most of it is under your control.
Of all the sleep tips you could ever read or hear about, the most important one is to stick to one sleep schedule—every day. This means going to bed and waking up at the same time each day. When sleep has a regular rhythm, your biological clock will be in sync and all of your other bodily functions will go smoother, including your sleep. You are probably squirming as you read this tip, thinking about your own sleep issues and how you have anything but a regular sleep routine.
A recent team of leading medical doctors and researchers examined all published studies to date on newer forms of sedative sleeping pills that most people take. They considered sixty-five separate drug-placebo studies, encompassing almost 4,500 individuals. Overall, participants subjectively felt they fell asleep faster and slept more soundly with fewer awakenings, relative to the placebo. But that’s not what the actual sleep recordings showed. There was no difference in how soundly the individuals slept. Both the placebo and the sleeping pills reduced the time it took people to fall asleep (between ten and thirty minutes), but the change was not statistically different between the two. In other words, there was no objective benefit of these sleeping pills beyond that which a placebo offered.
Set a Routine. If you get up early one morning and then sleep in the next, it can be hard to fall into a rhythm. For the 17 percent of Americans who do shift work, an erratic schedule may be part of the job. But if that doesn't apply to you, going to bed and waking up at roughly the same times every day can help you fall asleep faster and sleep more soundly.
