Hello readers! Sorry for the lengthy absence — I went on vacation for awhile, and have been nose-to-the-grindstone on various projects since I returned.
The vacation was a blast — five families went in on a mansion rental in Truckee and we all played around in the snow. Five families under one roof leads to some interesting conversations — both frivolous and serious. One topic that came up a few times was sleep. Not everyone was getting some. Why is it that so many adults sleep poorly? In our case maybe it was the copious amounts of booze being consumed, but even teetotalers sometimes sleep poorly.
Chronic sleep deprivation is one of the worst states of consciousness. Insomniacs are wide awake at night, groggy and irritable during the day, and miserable most of the time.
Insomnia can be triggered by any of the following:
- emotional trauma (loss of a loved one, money stress, health worries, etc.)
- physical trauma (injury, surgery, chronic pain, stroke, etc.)
- breathing problems, including asthma and sleep apnea, which lead to frequent awakenings
- poor sleep conditions (room too hot or too cold, noise, light, mattress or pillow too hard or too soft, biting insects, etc.)
- disruption of circadian rhythms (from working a night shift, traveling through multiple time zones, or even watching TV or using digital devices in the evening)
- overuse or sensitivity to physical stimulants (coffee/caffeine, B-vitamins, high doses of zinc, some medicinal herbs, raw garlic, many street drugs, many pharmaceuticals, some nootropics)
- too much alcohol
- depression or mania (a vicious cycle, because sleep deprivation can also cause depression or mania)
- nutritional deficiencies that may affect calcium metabolism and/or melatonin production
Insomnia can manifest either as sleep-onset (difficulty falling asleep), nocturnal awakenings, and/or poor sleep quality.
My Own Experience
I experienced several years of poor sleep quality when I was suffering from asthma symptoms. Changing my diet and taking certain supplements (notably vitamin D) got rid of my chronic lung inflammation and led to much better sleep quality.
I also didn’t sleep well for the first couple years of my daughter’s life, even though my wife did much more nighttime care-giving than I did. Kia seemed to be able to fall back asleep more easily after comforting our daughter back to sleep.
My sleep greatly improved during our 30-day experiment with no artificial light. The takeaway from that experiment was to dim the lights much earlier in the evening, and to install f.lux on my laptop.
While I have been fortunate enough to never experience severe, chronic insomnia, I have learned a fair amount about which supplements and lifestyle habits influence sleep. And in the last few months, I have added a supplement which has taken my sleep quality from “pretty good” to “very good.”
Here’s what I’ve learned so far:
Seven Point Plan for Better Sleep
1. Don’t panic, and embrace quiet wakefulness.
If you are unable to fall asleep or fall back asleep, practice enjoying the in-between state of quiet wakefulness. Not sleeping eight consecutive hours is not necessarily pathological, and insomniacs often underestimate how much they are sleeping. There is nothing wrong with lying peacefully in the dark for a few hours while your mind wanders and you get in touch with your subconscious mind. Instead of “trying” to fall asleep and worrying about not getting enough sleep, experiment with relaxing and being comfortable. Even if sleep does not come (or stay), you can still experience a restorative rest cycle (and, according to the study linked above, you may be sleeping without knowing it).
If you are truly restless and obsessing about something, get up and write down what’s on your mind. Use candlelight or a red-spectrum light so that you don’t disrupt melatonin production.
2. Improve your sleep environment.
Ideally, your bedroom should be dark and relatively quiet at night, with some natural light coming into the room at dawn. If you can’t control your sleep environment to this degree, wear earplugs and a sleep mask.
3. Get emotionally clear.
If you owe someone an apology, then apologize. If you’re in the wrong, make it right. If you’re depressed, then do something about it. If your life is on the wrong path, then find the right one. If you have seen things that no person should see and you are suffering from PTSD, consider MDMA-assisted therapy.
4. Improve your calcium metabolism and strengthen your bones.
Good sleep is related to the absorption and utilization of calcium. Unfortunately, just taking a calcium supplement rarely helps — there are too many cofactors to consider. From a dietary perspective, here’s what you need to do:
- Get enough dietary calcium — here’s a link to recommended intakes and sources. Dairy products (full-fat, organic) are a good option for people who are able to digest lactose and who are not allergic to casein; otherwise whole sardines, canned salmon, cooked greens, and almonds are good sources.
- Take supplemental vitamin D3 — enough to get your blood levels into the recommended range. This will increase calcium absorption, reduce your risk of cancer, and improve asthma symptoms. Most MD’s seem to be recommending about 1000IU a day, but this may not be enough if your levels are very low (I take between 2000 and 4000IU most days simply as a maintenance dose). Note: I take fat-soluble vitamins like vitamin D with breakfast, as I’ve noticed vitamin D in particular can have a slight stimulating effect.
- Take supplemental magnesium — a chelated form such as magnesium glycinate — at least 200mg a day. Magnesium works synergistically with calcium, helps promote deep sleep and relaxation, reduces tics and twitches, and promotes regular elimination.
- Take supplemental vitamin K2. Vitamin K2 increases bone density, reduces risk of heart disease, and prevents cavities. Dr. Mercola calls vitamin K2 the “traffic cop” for calcium, controlling where calcium goes in the body via modulation of the hormone osteocalcin. I take a small daily dose of supplemental K2 (50mcg of the MK-7 form), and also eat foods high in the MK-4 form of K2 (aged cheeses, poultry liver, butter from grass-fed cows). I have noticed a significant improvement in sleep quality since I started taking supplemental K2, in addition to dietary sources.
Nutrition is extremely important, but the right kind of exercise is equally important for dense bones and deep sleep (which tend to go together).
The ideal kind of exercise for strengthening bone is “high impact”; motions that actually cause the bone to slightly bend. This includes sprinting, jumping, and very fast walking. Exercises like swimming, slow walking, slow jogging, and most weight-lifting won’t benefit bone strength in the same way.
Why do bone health and deep sleep go together? I don’t completely understand the relationship on a hormonal level, but my layman’s interpretation is that bone density decreases slightly during sleep (because of lack of weight/impact on the bones — similar to life in space), and having strong healthy bones provides a buffer against this natural effect, in essence telling the body that it’s “OK” to sleep deeply and for a long time.
5. Reset your circadian rhythm and encourage melatonin production.
A whole post on this one. Artificial light, which we generally take completely for granted, is both highly convenient and horribly disruptive of natural circadian rhythms. If you “try to go to bed earlier” you will generally fail in the long-term. Turning lights way down or completely off in the evening is the only way to get to sleep earlier unless you are a freak of nature whose melatonin production is not disrupted by artificial blue-spectrum light.
6. Avoid stimulating foods and supplements in the afternoon and evening.
This sounds obvious, but which foods and supplements count as “stimulating” can vary greatly from person to person. I learned from my 23andMe data that I’m a fast caffeine metabolizer, which confirmed the results of my no coffee experiment (cutting out caffeine didn’t notably improve my sleep quality).
On the other hand, I’ve noticed B-vitamins, zinc, and a number of herbal supplements prevent me from falling asleep easily. If you are having sleep issues, take a break from all supplements for awhile and see if that helps (then add them in one by one, starting by only taking the supplement in the morning).
7. Reduce sinus congestion.
Sinus congestion leads to snoring and sleep apnea. Reducing or eliminating commonly allergenic foods (cow’s milk, wheat), and reducing immune “twitchiness” (by optimizing vitamin D levels, taking probiotics, and getting plenty of exposure to good old dirt) can reduce sinus congestion and improve sleep. A cool temperature in your bedroom can also help. Here’s more on this topic.
That’s my list. I hope it helps a few people out there get some deep restful Z’s!
It’s important to realize that getting older doesn’t necessarily mean you won’t sleep as well. If you’re over forty and you drink scotch every day and never break a sweat (and this has described me at times), the last two factors are going to negatively affect your sleep much more than the first. After some lifestyle and supplement adjustments, I often sleep better now than I did in my twenties (and certainly better than I did in my thirties, when I was partying more, heavier, and less fit than I am now).
And as a bit of a curiosity, here’s a map of sleep disturbances.
