Basically everyone I know is knackered, me included. But I didn't
imagine that there could be health problems associated with not
getting a good night’s rest. I recently read a book called “Light’s
Out: Sleep, Sugar and Survival” by T.S. Wiley which talks about the negative cumulative effects
of sleep deprivation (aging, hormonal imbalances, etc.) I asked one of
my doctors, Frank Lipman, for his opinion on the subject and the
result is the fascinating piece below, followed by some suggestions on
ways to sleep better.
Let's get some shuteye, people.
Why You Need It and How To Get More of It
by Dr. Frank Lipman
In addition to a healthy diet and regular exercise, getting enough restful sleep is the most important thing you can do for your health. Proper sleep is one of the keys to looking and feeling your best, yet it’s estimated that up to 70 percent of Americans are chronically sleep deprived. Unfortunately this is consistent with what I see in my NYC practice.
Chronic sleep problems interfere with your body’s natural rhythms and
rob it of the time it needs to restore itself. The incidence of many
diseases including diabetes, high blood pressure, heart attacks and
depression increases with a lack of sleep. Recent research has even
shown a connection between poor sleep and weight gain. We simply
weren’t built to just go, go, go. We were built to go, go, go and then
rest, rest, rest. We evolved according to the natural rhythms of
darkness and light; our bodily functions reflect this and undergo
similar fluctuations. They perform best when we live in accordance, as
much as possible, with these cycles.
It is during sleep that your body’s innate healing capacities kick into full gear. Your immune system gets revitalized. Hormones and metabolism are balanced, and general maintenance, fine-tuning and repair of all bodily systems is performed. A good night’s sleep, not just once in a while, but on an ongoing basis, is absolutely critical for your good health.
Insomnia is not a disease, but is usually a symptom of a deeper underlying bodily imbalance which can be corrected. For real success, the causes of the imbalance must be removed.
The most common underlying causes of chronic sleep issues are:
- Chronic stress or an over-stimulated nervous system.
- Hormonal imbalances (adrenal, thyroid and reproductive hormones in particular.)
- Poor diet (too much sugar, processed and refined foods and the common foods that cause sensitivities: gluten and dairy.)
- Stimulants or substances that can affect sleep (alcohol, caffeine, medications, recreational drugs, herbs, and even some vitamins.)
- Gastro-intestinal dysfunction
- Chronic pain
- Sleep Apnea
Although each of us is unique and, ideally, treatment should be individualized, my experience shows that the most effective long-term strategy for overcoming the most common type of insomnia in our fast-paced world is to better attune our bodies to the natural rhythm of darkness and light. This ultimately brings it back in sync with its natural rhythm. This can be done, for the most part, by changing bad habits and behaviors. In my practice, by doing this, I have seen a normalization in hormonal imbalances and a calming of the over-active nervous system, the two most common causes of sleep disorders.
Night and Day
As a result of living in tandem with the predictable patterns of day and night for thousands of years, these 24 hour cycles and rhythms became imprinted in our genes and, over time, we have developed internal body clocks that run in sync with nature. They are comprised of a variety of rhythmic patterns influencing every aspect of bodily function including hormone levels, digestion, body temperature and sleep.
But still our biology has not yet caught up with our ability to live without rest. And one of the most fundamental stresses on our systems is that we are living so out of sync with the natural fluctuations of light and dark. Our bodies evolved in dependence on signals from the sun, but to a large extent, we now get up without the sun, go to bed long after dark, work longer and longer days indoors under artificial lighting and spend little time outdoors, even in summer. During the day, we receive artificial light from fluorescent bulbs rather than the vitamin D-rich sunlight that our bodies need. Then, at night, when we need the dark to trigger essential melatonin production, excessive light throws our body rhythms out of balance even more.
Since the invention of the light bulb, obvious as its benefits have been, our lifestyles have really changed. Staying up all night can really sabotage our health. With light as with food, we must be careful of being overfed and undernourished. It becomes all too to easy to miss the very signals that regulate almost every system in the body, signals we’re primed to receive and without which we cannot function properly.
It’s essential to understand that it’s not just what you do at night that affects your sleep. How you go about your day and shift into the evening also plays a big role in how well you sleep. So, I’ve put together some general sleep-friendly tips, broken down into daytime, evening and night time to help you start thinking in terms of how your body is affected by the day/night cycle and how you can get more in sync with it.
Maintaining a sense of calm throughout the day, getting some natural
light and avoiding stimulants is essential for restoring normal sleep
Wake Up Right
Sleep researchers at the Mayo Clinic believe that if you need an alarm
clock to wake you up, it’s a sign that you’re not sleeping right.
Alarm clocks interrupt the sleep cycle and prevent sleep from
completing naturally, pushing sleep problems into succeeding days.
Dawn simulation devices are much more effective at establishing a
healthy sleep cycle and gently rousing you from sleep.
Take Mindfulness Breaks
Close your office door, or find a quiet spot somewhere and get comfortable. Take 5 minute breaks throughout your day to focus on your breath. If that’s challenging, then focus on your feet and then your hands. Feel them for a few minutes; become aware of them. This will calm you down. Quieting and slowing your mind calms the body, which is the perfect antidote to the over-stressed state we are often in.
Get Some Natural Sunlight Every Day
We live and work in artificially lit environments and often miss out on the strongest regulatory signal of all, natural sunlight. Researchers at Johns Hopkins University found that it’s actually light itself that governs our sleeping patterns. As sunlight enters our eyes it regulates and resets our biological clocks, which involves triggering our brains and bodies to release specific chemicals and hormones that are vital to healthy sleep, mood, and aging. Studies show that adults across America are spending less than one hour outdoors each day, far less than in the past. Try to get at least half an hour of regular exposure to natural sunlight a day.
Exercise is one of the best defenses against insomnia because it increases the amplitude of our daily rhythms. It signals the body to promote deeper sleep cycles. Both aerobic and anaerobic exercise work well. The best time to exercise is 4 - 6 hours before bedtime, but studies also show that people are more likely to stick to a routine if they exercise first thing in the morning. In general try to avoid exercising after 8pm as it may be too stimulating to your body and make it more difficult to get to sleep. This effect does vary, however, from individual to individual. Make an exercise plan for yourself that works for you and that you can stick to.
No More Caffeine
Caffeine, even in small doses, blocks sleep neurotransmitters, the calming chemicals your body makes to make you sleepy. If you have a problem with sleep, you must cut out all caffeinated beverages, even your morning cup of coffee. But caffeine is not just in coffee. It’s in colas and other soft drinks, teas, including herbal teas, chocolate and some medications. There’s even a little caffeine in decaffeinated coffee. Caffeine is a powerful stimulant with effects that can last up to 7 hours. For people who have liver problems, or who are taking oral contraceptives or other medications (Anacin and Excedrin, for example), caffeine’s effects can last much longer. It interferes with the bodies natural regulatory rhythms and chronic use of it can create a chronic bodily imbalance.
Try an Elimination Diet
Go for it! For two weeks, eliminate sugar, corn syrup, sodas, refined
grains and processed foods. These are metabolic disruptors which
overstress the organs involved in hormone regulation and can seriously
affect your sleep cycles. In addition, avoid dairy and gluten
products, especially wheat, for the two weeks as these can cause food
reactions or sensitivities which can affect your sleep cycle, too.
Eat In Accordance With Your Body Rhythms
Your digestive system function peaks at lunchtime, so most of your food should be eaten by then. Your metabolism slows down in the late afternoon, leaving you poorly prepared to digest a large dinner; in other words: have a small one. Eat it early, at least 3 hours before going to sleep. Give your body a chance to recover and rebuild, instead of having to work on digestion while you sleep.
Note the Medications or Other Drugs You Are Taking
Medications such as antihistamines, diuretics, antipsychotics, antidepressants, decongestants, asthma medications, and some blood pressure medicines can cause sleeplessness. If you’re taking any necessary medication that interrupts your sleep, talk with your doctor about an alternative.
Expecting to go from full speed to a standstill without slowing down first is unrealistic. You should prepare for sleep by giving your body the right signals. It takes time to produce the sleep neurotransmitters needed by the brain’s sleep center to release the hormones that will allow you to sleep. Reducing stimulation in the evening before going to bed boosts the production of sleep hormones. Taking some time to wind down and prepare your environment before hopping into bed will encourage a good nights sleep.
Create an Electronic Sundown
By 10 pm, stop sitting in front of your computer or TV screen and switch off all other electronic devices. They are too stimulating to the brain and inhibit the release of these sleep neurotransmitters.
Prepare for Sleep
Dim the lights an hour or more before going to bed, take a warm bath, listen to calming music or soothing sounds. Remove any distractions (mental and physical) that will prevent you from sleeping.
Practice a Relaxation Technique
Too much stress is one of the most common causes of sleep disorders so learning to relax is key. Many people tell me they can’t switch off their racing minds and therefore have trouble sleeping. Do some breathing exercises, restorative yoga or meditation. These will calm the mind and reduce the fears and worries that trigger the stress.
Creating consistency and optimizing the sleep environment are essential.
Create a Regular Routine
Going to bed around the same time, even on weekends, is the most important thing you can do to establish good sleep habits. We stay up late on weekends, expecting to make up sleep later or use the weekend to make up for lost sleep during the week. Both practices disrupt bodily rhythms and late night weekends, in particular, can cause insomnia during the workweek. We often think we can make-up for lost sleep by going to bed extra early another night, but the body clock’s ability to regulate healthy sleep patterns depends on consistency. A regular sleep rhythm reminds the brain when to release sleep and wake hormones, which in turn effects all the other hormones, ultimately effecting our overall health.
Keep the Room As Dark As Possible
Our bodies need complete darkness for production of the important
sleep hormone, melatonin. If your bedroom is not pitch dark when you
go to sleep, it interferes with this key process and disrupts your
circadian rhythms. Even the tiniest bit of light in the room can
disrupt your pineal gland’s production of sleep hormones, disturbing
your sleep rhythms. Look around your bedroom for glowing indicator
lights and try to remove or cover them: alarm clock read-outs,
charging indicators on cell phones or PDA’s, the monitor on your
computer, battery indicators on cordless phones or
answering machines, the DVD clock and timer etc. Cover all the lights
of any electronic device and use dark shades or drapes on the windows
if they are exposed to light. If any of this is not possible, wear an
Keep the Room Cool
Lowering ambient temperature sends a feedback signal to the brain’s sleep center that it's nighttime, and that it needs to release more sleep hormones. A sleeping temperature of 60 to 65 degrees is best for most people, even in the winter. In hot weather, use a floor or ceiling fan to create a breeze, or an air-conditioner set at about 70 degrees. Interestingly, I have heard from a number of patients with chronic cold feet who swear by wearing socks to bed.
Block Out Noise
If noise from the street, an upstairs neighbor, pets or a snoring bed
partner is a problem, try using earplugs, an electronic device that
makes “white noise” or a fan that hums to drowns out the surrounding
Do Not Rely on Sleeping Pills to Fall and Stay Asleep
Sleeping pills mask sleep problems and do not resolve the underlying causes of insomnia. Many sleep studies have concluded that long-term use of sleeping pills, whether prescription or over the counter, do more harm than good. They can be highly addictive and studies have found them to be potentially dangerous. If you have been taking them for a long time, ask your doctor to help you design a plan to eliminate them.
Don’t Use Alcohol to Fall Asleep
Because of alcohol’s sedating effect, many people drink to promote sleep. Alcohol does have an initial sleep inducing effect, but as it gets broken down by the body it sends the wrong metabolic signals which can cause you to wake up later on. It usually impairs sleep during the second half of the night leading to a reduction in overall sleep time.
Take Nutrients That Calm Down the Nervous System
Instead of sleeping pills or alcohol, try some supplements or herbs that have a calming effect half an hour to an hour before bedtime. Magnesium (300-600 mg) can be helpful as can calcium. The amino acids, L theanine (100-500mg), 5 HTP (50-100mg), taurine and GABA, and herbs like lemon balm, passion flower, chamomile, magnolia and valerian root can also help.
Try Some Melatonin at Night
For some people, melatonin can be extremely helpful. The dosage I usually use is anywhere between half a mg to three mg right before bedtime (sublingual tablets are better than oral). Melatonin is good for initiating sleep, not maintaining it.
Don’t Make Sleep a Performance Issue
Often just thinking about sleep affects your ability to fall asleep.
What happens frequently is that the way we cope with the insomnia
becomes as much of a problem as the insomnia itself. It often becomes
a vicious cycle of worrying about not being able to sleep which leads
to worsening sleep problems. Like so many things in life, it is about
letting go and going with the flow. If you can’t fall asleep, don’t
fight it – instead try to do something that will help you relax, and
then try again. Sleep needs to become a natural rhythm like breathing,
something that comes automatically.
Although the vast majority of my patients have been helped with these general tips, addressing the particular causes more specifically in some cases is necessary. Those with thyroid, adrenal or gastro-intestinal dysfunction, and women in peri-menopause or menopause may need additional targeted treatments. Similarly for women in peri-menopause or menopause. Those in pain may need more specific treatments and for chronic insomniacs, especially heavy snorers and those who are obese, it is a good idea to rule out Sleep Apnea as the cause. This is a serious condition that affects at least 12 million Americans, many of whom have not been diagnosed.
I know from personal experience and from the many patients I have seen, that incorporating these sleep tips into our lives has made a huge difference. There is nothing quite like going from being worn out and exhausted to bouncing back to life when you find a new sleep groove; start catching your sleep wave and start sleeping well. The British poet Thomas Dekker observed that sleep is “the golden chain that ties health and the body together.” I couldn’t agree more. Here’s to a good night’s sleep on a regular basis.
goop Tips for a Heavenly Bed
They say you spend nearly a third of your life in your bed so you might as well as make it as comfortable and luxurious as you can afford to.
1) Linens should be 100% cotton in a high thread count, if your budget allows. Here are a few brands that offer high-quality linens:
2) Lavender essential oil is great for sprinkling on sheets and pillows. Its fresh sent is said to be relaxing and help you sleep.
3) If you have the time and inclination, ironed sheets make a world of difference.
4) Use organic fabric conditioner when you wash linens to make them feel fresh and soft.
5) For super luxurious pillows and duvets, Hungarian, Canadian and Polish goose down is recommendable. You can buy a light comforter for the summer and a medium one for when it’s colder and then combine the two for the winter. Cloud 9 Comforts has a vast selection for all bedding needs.
6) We love the Serta Perfect Sleeper Pillow Top Mattress. My guests always say it’s like sleeping on a cloud. In the UK, Vi-spring makes the most comfortable mattresses.
7) To avoid a ruthless wakeup from a beeping alarm clock, Serenity Health offers a few that simulate gentle sounds and even a dawn
simulator which imitates the light rising in the morning, to wake you up right.
