How To Sleep Better At Night
In this blog, I want to talk about sleep. One of the most common complaints I hear from patients in my practice is that they can’t sleep, and they ask what they can do to sleep better at night. It’s brought up so often that I’ve created a list of rules to follow to get better sleep at night. But first, some facts about sleep… and the lack thereof.
While sleep requirements vary slightly from person to person, most healthy adults need between 7 to 9 hours of sleep per night to function at their best. Children and teens need even more. And despite the notion that our sleep needs decrease with age, most older people still need at least 7 hours of sleep per night for optimal functioning.
We all know that good sleep is important. But why? I mean, if we don’t get enough sleep, we’ll be tired, but other than that, it really doesn’t matter, right? Wrong. In terms of importance, getting good sleep, and enough of it, is actually right up there with eating a healthy diet and exercising regularly. Poor or not enough sleep is known to have negative consequences on hormone levels and brain function, and can cause weight gain and increase the risk of obesity and diseases like diabetes and heart disease. On the flip side, adequate or good sleep can keep you healthier, help you maintain physical fitness, and think more clearly and concisely. Unfortunately, sleep quality and quantity have both decreased in recent years, and millions of people battle chronic insomnia for their entire lifetimes. Because it plays such a key role in your health, getting good sleep should be a priority in your life. Toward that end, below are my fourteen rules for good sleep.
Rule 1: Get bright light during the day. Natural sunlight is preferable, but artificial light works too. Your body’s natural clock is called your circadian rhythm; it links your body, brain and hormones, keeping you awake during the day when appropriate and telling you when it’s time to sleep at night. Daytime light exposure keeps your rhythm happy and in sync, improving daytime energy and alertness as well as nighttime sleep quality and duration.
Rule 2: Avoid blue light in evenings and at night. What is blue light? Blue light is what is emitted from your computer, laptop, iPad and smartphone. While daytime light exposure is beneficial, nighttime light exposure is not. This is because of its impact on your circadian rhythm; it tricks your brain into thinking that it’s daytime, and this reduces natural hormones like melatonin, hindering sleep. The more blue light you expose yourself to, the more disruption you’ll have in your sleep. There is a solution for this; there’s an app for your smartphone that filters out the blue light. There’s also something called “F.Lux” that you can put on your computer or iPad which will block out the blue light in those devices as well. So remember, blue light is a serious factor. If you are on your iPad or your computer at night, you’re not going to sleep well.
Rule 3: Avoid caffeine, Captain Obvious. 90% of the US population consumes caffeine on a daily basis, mostly in coffee and energy drinks/ shots. Here are some approximate caffeine counts: an 8 ounce cup of coffee has 95mg of caffeine, a 5-hour energy shot has 75mg and a Red Bull drink has 120mg of caffeine. While caffeine can enhance energy and focus, it can also wreck your sleep. Caffeine stimulates the nervous system, and this can prevent the mind and body from relaxing and falling into a deep sleep. Caffeine can remain elevated in the blood for 6 – 8 hours after ingestion, so consuming caffeine after 2pm is not the best idea, especially if you’re sensitive to it or already have trouble sleeping. In addition, regardless of when you consume it, you should limit caffeine intake to 200mg per day or risk losing sleep over it.
Rule 4: Watch naps during the day. While short power naps can be beneficial for some, taking long naps during the day can negatively impact your sleep. How? That wiley circadian rhythm again! Napping during the day confuses your internal clock, disrupting your sleep-wake cycle and potentially leaving you with problems falling asleep at night.
Rule 5: Try Melatonin. Melatonin is a naturally produced sleep hormone that tells your brain when it’s time to relax and head to bed. Melatonin supplements are an extremely popular over-the-counter sleep aid, helping people to fall asleep more quickly. I usually recommend between 2 and 4mg of melatonin at (or shortly before) bedtime. I find that some patients get daytime hangover from it, so be aware of that and possibly decrease the dose to see if that minimizes the hangover.
Rule 6: Regulate your sleep-wake cycle. How? By getting up at the same time every day and going to bed at the same time every day…. even on weekends. I know, that last bit is a bummer. Our old friend circadian rhythm is at work again here. The circadian rhythm is basically a loop, and irregular sleep patterns disrupt it and alter the melatonin levels that tell your body to sleep. The result? Not sleeping. I recommend that you go to bed at the same time every night and that you set an alarm to get up at the same time every day, no matter how tired you may be. After some time, you will probably find that you wake up on your own without the alarm and that the consistency of your schedule will give you better sleep quality.
7. Try additional supplements for sleep. There are a few dietary supplements that have been found to induce relaxation and help you sleep.
Glycine: This is a naturally produced amino acid shown to improve sleep quality. I recommend 3 grams at night.
Magnesium: This is an important mineral found in the body; it is responsible for over 600 biochemical reactions within the body, and it can improve relaxation and enhance sleep quality. I recommend 100-350mg daily; start at the lower dose and increase gradually if necessary.
L-theanine: Another amino acid, L-theanine can induce relaxation and sleep. I recommend 100–200mg before bed.
Lavender: A powerful herb with many health benefits, lavender can induce a calming effect on anxiety and help induce sleep. I recommend 160mg at night.
Rule 8: No alcohol. I’m sure we’ve all heard people say that a nightcap “helps them sleep better.” Don’t ever believe it…it’s total crap. Downing even one drink at night can negatively alter hormone levels like melatonin, disrupting the circadian rhythm and therefore sleep. In addition, alcohol is known to increase, or even cause, the symptoms of sleep apnea such as snoring, which also disrupts sleep patterns and causes poor sleep quality.
Rule 9: Create a cool, dark and quiet bedroom environment. Minimize external noise and light with heavy blackout curtains and remove devices that emanate artificial light like digital alarm clocks. Make sure your bedroom is a relaxing, clean, calm and enjoyable place. Keep the temperature very cool, I usually recommend 70 – 72 degrees, because the weight of blankets is very comforting. You can even buy weighted blankets for adults and children; I’ve heard many patients say they really relax the body which in turn helps them fall asleep.
Rule 10: No eating late at night. Late-night eating may negatively impact the natural release of HGH (human growth hormone) and melatonin, which leads to difficulty falling asleep. Also, I think that most of the time, people eat bad things late at night, things with a lot of sugar and things high in fat, like chips, candies, and cereal. These all interfere with sleep. Generally, when the body goes into a digestive mood, as it does after eating, it doesn’t want to sleep.
Rule 11: Relax and clear your mind. Many people have a pre-sleep routine that helps them relax to prepare for sleep. Commonly suggested for people with insomnia, pre-sleep relaxation techniques have been shown to improve sleep quality. Strategies can include listening to relaxing music, reading a book, taking a hot bath, meditating, deep breathing and visualization. Stress is a common reason for trouble falling asleep and poor sleep quality and quantity. If your problems are keeping you up at night, you have to come to some resolution on how you’re going to handle those issues in your life so that you can put them to rest, go to bed, and get some sleep.
Rule 12: Spend money on a good quality, comfortable mattress, good pillows and good linens. You’re going to spend a third of your life in your bed…don’t cheap out when it comes to the matress and bedding; spend the money. Make sure your mattress is large enough, comfortable and high quality. Studies have shown that quality mattresses significantly reduce back and shoulder pain. And buy good quality, high thread count (800 thread count minimum, but higher if you can) cotton sheets…they’ll get softer with every wash. Find pillows that feel most comfortable and supportive for you. You may have to try multiple pillows before finding the perfect one, but the search and cost are necessary, and your neck will thank you for it. A quality mattress and pillows and great linens can be an investment, but well worth it. You’ll have them for some time and you’ll be happier for it when you get in bed at night and go “Aaaaahhhh.”
Rule 13: No exercising at night. While daily exercise is key for a good night’s sleep, doing it too late in the day may cause sleep problems. This is because exercise acts like a stimulant, increasing hormones like epinephrine and adrenaline, which increase alertness. Alertness is the antithesis of the relaxation you need to fall asleep. Basically, exercise hypes you up, making it difficult or impossible to fall asleep.
Rule 14: No fluids before bed. While hydration is an absolute necessity for health, it’s best to restrict fluids for one to two hours before bed. You should also use the bathroom right before going to bed, as this may decrease your chances of waking in the night. The reason for this rule is fairly obvious: a full or partially full bladder will wake you up in the middle of the night to go to the bathroom, and that’s a total drag for you and likely for whomever shares your bed.
So those are my 14 rules for better sleep. And now I’ll say goodnight, sleep tight, and don’t let the bedbugs bite!
