Science Daily reported recently that a new study by researchers from St. Luke’s-Roosevelt Hospital in New York City and Columbia University seems to have found a link between how well we sleep and how badly we eat. In the study, people who were didn’t get enough sleep tended to feel hungry more often, eat more, and gain more weight. While this doesn’t mean we can somehow “sleep away the pounds,” it does suggest that sleeping well makes it noticeably easier to eat well–and we already know that eating well, in turn, helps us sleep better.

In other words, paying special attention to getting enough sleep, which for most of us means making a decision to go to sleep earlier at night, can help us eat better and feel more healthy, which in turn can help us sleep even better: a snowball effect, though I can’t tell you whether the effect would be small or large.

You can read the Science Daily article here, or click on the following link to see the abstract for “Alterations in sleep architecture in response to experimental sleep curtailment are associated with signs of positive energy balance” from the American Physiological Society.

You could make a good argument based on research that meditation is one of the best things we can do for physical health, mental and emotional well-being, and general happiness. Meditation focuses attention, relieves stress, increases the ability to cope with problems (including chronic pain), improves sleep, and provides a welcome reality check.

Popular, but not popular enough
So with that in mind, it’s a little surprising that so few people meditate regularly. According to this handy page from the National Institutes of Health citing a 2007 U.S. government survey (“Complementary and alternative medicine use among adults and children: United States, 2007“), only 9.4% of adult respondents had meditated at all in the last 12 months–and many of those 9.4% surely don’t meditate regularly. On the one hand, this is a huge number: for instance, based on that figure it seems likely that the great majority of U.S. residents, whether or not they’re aware of it, know someone who meditates at least every once in a while. On the other hand, meditation seems to benefit virtually anyone who gives it a good try, so the fact that so few Americans do meditate regularly is disappointing.

Some ideas as to why people don’t meditate
I imagine one major reason many people don’t meditate is that it still comes across as being foreign or New Agey, creating a barrier for people who aren’t comfortable with those labels. About those of us who have at least tried it, I began to realize recently when reading one woman’s account of her meditation experiences that many of us just don’t feel like we’re good at it.

That’s certainly been true of me sometimes. I’ll start meditating, and then I’ll have a thought about something, interrupting the meditation. Rather than letting the thought go, I sometimes tell myself to stop having thoughts, then chastise myself for getting into a mental conversation about thinking, then rebuke myself for chastising myself, then realize that the rebuke is a thought and tell myself to stop having thoughts. (I’m not even exaggerating.) While meditating, a person can easily feel distracted, taken by surprise by unexpected feelings or realizations, uncomfortable, unsure, or silly.

Why meditation problems are not a problem
The freeing thing to realize–or at least it’s a real help to me–is that there’s no need to be perfect at meditating for it to be helpful. It’s also likely that everyone else who learns to meditate has many of the same problems to one degree or another. Certainly, a monk who has been meditating hours per day for decades is probably going to be a lot better at the practice than you or I, but there’s no reason to believe such people didn’t originally have many of the same meditation issues that crop up for me or you, or that these issues completely prevent us from experiencing the benefits of meditation. Even poor meditation has a lot of good effects.

Having a good day–a day when things are going well, when you feel in a groove and are making good choices–can just happen, but it can also come from good preparation (see “How Preparation Enables Stronger Willpower“). Here are some ways we can prepare the night before to have a particularly good day. In a follow-up article, I’ll talk about things we can do in the morning to start a day off on the right foot.

• Plan extra time into the next morning. The more we have to rush in the morning, the more tense we tend to be and the more likely something will go wrong–or that a slight delay will be a serious problem instead of a nuisance. Also, starting the day off well generally requires having a little time in the morning to think, and ideally time to meditate and/or exercise.
  If you find yourself being late in the mornings, you can change that by following the recommendations in “How Not to Be Late: The 8 Principles of Being on Time.”
• Get a good night’s sleep. It can be difficult to change our nighttime habits to get more sleep or to get enough but get up earlier, yet the payoffs are much higher, as a rule, than, say, getting an extra hour to watch TV. See “18 Ways to Get a Good Night’s Sleep.”
• Solve problems in advance. If you can predict some of the trouble you may run into during the day–like getting into a bad mood because of a meeting with someone you don’t like, or having to get past a counter full of free bagels while trying to lose weight–you can picture solutions and make plans. It’s much easier to act on a plan you’ve already made when trouble arises than to improvise one on the spot, especially if you’re distracted or overwhelmed. You may even want to write some of these solutions down to review in the morning.
• Choose one good thing to get done early on. Many of us have a lot of things we want to accomplish on any given day, but choosing one specific thing that especially needs to get done or that is particularly valuable can make it much easier to focus on and accomplish that thing early in the day, and that accomplishment can boost motivation and mood powerfully.

Author and fellow Codex member Elaine Isaak posed this question:

So as I was tossing and turning last  night, it occured to me that the one area where I’m not sure I *can* effectively apply my willpower is in getting a good night’s sleep.  I can’t WILL myself to sleep the way I might will myself to get up on time to start writing or to go to the gym.  I wondered if you have come across any research that tackles this, or have any tools to suggest?

I have to agree with Elaine on not being able to will ourselves to sleep by sheer determination, but fortunately I do know of a number of ways to get to sleep and to sleep better, based on research. Understanding that serious problems with insomnia are worth seeing a doctor about and that these recommendations are not professional medical or psychological advice … here they are:

Long-Term Habits

1. Plan your schedule so that you can get to sleep at a decent hour and still be able to wake up if you want to. If there are things you need to do before going to bed, do them earlier in the evening to make sure they don’t push your bedtime back.

2. Figure out how much sleep you actually need by keeping track of how much sleep you’re getting each day and whether that turned out to be enough. This may change over time, or under different circumstances (such as in stressful periods or with more or less exercise).

3. Get on a steady schedule with your sleeping hours. Staying up late on weekends or going to bed at different times every night, for instance, can sometims interfere with your body’s attempts to establish a natural sleep schedule.

4. You may need to make your bed an environment you associate mainly with sleeping (and, if appropriate, sex). Take activities like reading, using a laptop computer, or watching TV out of bed if your bed doesn’t feel like a place that naturally relaxes you.

5. On mornings when you don’t have to get up right away, if any, don’t sleep in for long periods, as this may tend to muck with your ability to sleep that night. More sleep isn’t always better.

6. Take steps to make sure you have the physical comfort you need, to the best of your ability: a firm, comfortable mattress; good ventilation; a comfortable temperature; etc. For me, one of the most relaxing features of my bedroom in summer is a fan pointed at the bed. You may also find it more comfortable to use a non-illuminated bedroom clock, although this is admittedly inconvenient if you are up in the middle of the night and want to know what time it is.

Daily Habits

7. Watch out for caffeine and consider cutting it out for a little while if you’re having sleep problems. Remember that in addition to regular coffee, most sodas, black/green/white tea, and chocolate contain caffeine, and that even decaf coffee and decaf tea contain some caffeine–just a reduced amount. Other stimulants to be careful of include ginseng and nicotine.

8. Exercise during the day! Be active! Regular exercise contributes to very good sleep.

9. Watch out for alcohol: while it can help you fall asleep more quickly, it also can cause sleep problems. According to MayoClinic.com, “it prevents deeper stages of sleep and often causes you to awaken in the middle of the night.”

10. Don’t eat or drink a lot late in the evening. Either can cause physical discomfort that keeps you up at night or that can interrupt an otherwise sound sleep.

Before bed

11. Stretch, either doing yoga or basic stretching techniques. Stretching will release tension and improve blood flow.

12. Before bed, steer clear of things that might stir you up, like watching television, reading a suspenseful novel, or taking on stressful tasks. Relaxing activities will help settle you down so that you can sleep more easily. These can even include things like picking up and cleaning around the house to set things in order, or gathering things you’ll need the next day. The relative mindlessness of these tasks, the mild physical activity, and the way this prevents you from having to worry about getting things done in the morning are all conducive to good sleep.

13. Consider meditation, for instance body scan meditation, in which you focus your attention on each part of your body in turn and allow it to relax. Meditation can help still mental chatter and create a serene state of mind.

14. Ask a romantic partner, family member, or friend to give you a massage in the evening. This is an excellent means to rope someone into giving you a free massage, so don’t miss out.

In the moment

15. If you find yourself kept up by specific worries or general anxiety, try idea repair, journaling, or talking things out with someone who cares about how you’re doing.

16. Soft earplugs are great if you’re having trouble with noise. There’s a picture of the kind I like in this post.

17. If you’re obsessing about making yourself sleep, you may want to get out of bed, go sit on the couch, and read a book or listen to music or watch a movie that you’ve already seen, turned down low. These kinds of activities can engage your attention in a more relaxed way that may allow you to fall asleep more easily. Just make sure to have a comfortable couch.

18. In bed, listen to low music or a relaxation CD. Like the tactics mentioned in the previous item, this can help relax you when your mind is overstimulated.

In a recent e-mail to me, a correspondent talked about the problem of not having energy left after her daytime obligations:

My major problem is I have some studying to do and I am not able to do anything once I am back home. I am so tired. I’m basically brain dead too. I need the weekend to recuperate and so I am not productive at all during the weekend.

It’s a common problem: most of us seem to have days when the energy we want to have just isn’t there. Here are nine approaches that can help dredge up energy when no energy seems to be available.

1. Are you getting enough sleep? (See How Much Sleep Do You Need? 8 Hours Isn’t for Everyone) If not, are there ways you can get more, for instance by giving up a small amount of recreation time?

2. If worry is tiring you out, there are some things you can do to relieve the worry and leave more energy for getting things done. These include idea repair (see How to Detect Broken Ideas, How to Repair a Broken Idea, Step by Step, and Examples of Broken Ideas (Cognitive Distortions)), meditation (see Strengthen Willpower Through Meditation), brief walks in natural surroundings (see The Benefits of Quick, Easy, Pleasant Exercise), talking with a trusted friend or family member about worries you have, and writing in journals. Worry not only saps energy, but also makes it harder to use what energy you do have for constructive things.

3. Try to get into flow (see Flow: What It Feels Like to Be Perfectly Motivated and Some Steps for Getting into a State of Flow), a state where you’re concentrating fully on what you’re doing. Even if you feel tired at the beginning, if you really get deeply involved in a task that interests you, you can start feeling energized by the task itself.

4. Choose things to eat that will make you feel good in the short term. Of course this tends to mean whole grains, fruits and vegetables, and lean protein. Fats take a lot of digestive energy to break down and tend to make a person feel groggy, as does eating too much. Sugars tend to give a quick boost and then drop a person into a low that’s a good bit more tired than they were before the sugar high. Caffeine also tends to give a boost at one point but take much more out later. Drink enough water to ensure you’re not dehydrated: dehydration is a common cause of fatigue, as detailed in this article on the Psychology Today site. The article also contains other good anti-fatigue eating advice, like getting plenty of iron.

Of course it’s difficult to make healthy eating choices sometimes, but it can help to think about wanting to feel good right away from good food choices instead of thinking more of their long-term benefits, (though of course the long-term benefits are great, too).

5. Work yourself into an excited state about a project. Again this tends to mean talking to someone or writing about the project. This is similar to getting into flow, as it engages your mind and your interest and wakes you up.

6. Put on music that gives you a lift (see How and Why Music Changes Mood).

7. Think about things that make you happy. Reflecting on good things that happened to you over the last day, anticipating something you’re looking forward to doing soon, or thinking about someone whose company you really enjoy can make your mood more buoyant.

8. Tidy up. If your environment is messy or chaotic, you may tend to feel a little exhausted just being in it from the constant, low-level annoyance of clutter or mess. (See How Tools and Environment Make Work into Play, Part II: Letting Your Environment Help You.)

9. Meditate, or sit still for a short while. Meditation (see Strengthen Willpower Through Meditation) can help release tension and create calm and focus. If you’re not experienced in meditation, one easy way to start is with this 15-Minute Online Guided Meditation from Kelly McGonigal. Just sitting still gives you a chance to relax and let go. If you take this approach, don’t try to do anything, keep TV and music off, and just gaze out the window.

It was in April of 2009 that I started the Willpower Engine. 132 posts and more than eight months later, I’ve been interested to see what kinds of articles have gathered the most attention. And while the reasons one post might get seen more than another are a little chaotic–more of an indication of successfully getting the word out than of anything–it’s also true that some of my favorite posts show up on this list.

So here, without further ado and with a few brief notes, are the top 10 Willpower Engine posts this year.

#10 – How Feedback Loops Maintain Self-Motivation – Feedback loops are one of the most useful of all tools for maintaining motivation. Keeping focus and really thinking about our recent experiences in light of our goals can keep those goals alive and moving forward in our minds.

#9 – How Much Sleep Do You Need? 8 Hours Isn’t for Everyone – I had been wondering for years if “8 hours” was really the amount of sleep everyone needed, and it turns out it isn’t. The way to learn how much really is needed turned out to be very simple.

#8 – Do you have enough talent to become great at it? – The books that informed this post were revelatory for me. Our culture takes the existence of natural talent as a given–yet the idea of “talent” turns out to have some serious flaws, which create some incredible opportunities when we realize them.

#7 – How To Improve Willpower Through Writing Things Down: Decision Logging – When I first tried Decision Logging, I thought it might be a magic bullet. It turns out to require too much time and attention to do all the time, so it’s not a magic bullet–but it can give self-motivation a very powerful boost by focusing attention and sparking insight.

#6 – How to Strengthen Willpower Through Practice – The idea of willpower as a muscle that can be strengthened by exercising it has some limitations–but in many ways, this picture of willpower holds true, and strengthening our natural good inclinations is a very valuable things to be able to do.

#5 – 7 Key Self-Motivation Strategies for Writers – This post was an early precursor to my free eBook, The Writing Engine: A Practical Guide to Writing Motivation, and it offers some of the most immediately useful advice I have for writers who want to write more.

#4 – How Long Does It Take to Form a Habit? – There are a lot of places out there on the Web that make claims as to how long it takes to form a habit, but very few seem to be based on anything more than someone’s rough guess. Fortunately, there is a bit of research done to look at the question more carefully, and this post is based on that research.

#3 – Broken ideas and idea repair – Like feedback loops, idea repair (called “cognitive restructuring” in the psychological literature) is one of the most useful skills this site has to offer: it provides a way to understand negative emotions and bad moods and turn them around. I later followed this post up with some additional, practical information in How to Detect Broken Ideas and How to Repair a Broken Idea, Step by Step.

#2 – 6 Key Self-Motivation Strategies for Losing Weight – Weight loss has been one of the key areas where I’ve made use of self-motivation in my life, and with two thirds of adult Americans being overweight, I’m in good company for wanting to make that change. As demoralizing as trying to lose weight can be, it is possible, and this post offers some of the best information I have as to how to best do it.

#1 – How Tools and Environment Make Work into Play, Part I: The Example of Scrivener – It may seem surprising that the most popular post on the entire site focuses as much on a particular product as it does on a motivation strategy, but the more I think about it, the more it makes sense to me that this post is read as much as it is. Any really good tool–like Scrivener for a writer, or a really excellent brush for a painter, or the arguably industry-changing Red One camera for an indie filmmaker–provides a whole lot of motivation with very little of the usual investment of time and effort. Money aside, who doesn’t want instant motivation improvement?

And there are the most popular Willpower Engine posts for the year. What about the coming year? Your comments, ideas, and messages are always appreciated and of interest. Write me if you have ideas about what kind of article would be of the greatest use to the greatest number of people in 2010.

In my previous article, I offered four ways to make self-motivation easier, and talked about stacking up advantages ahead of time instead of waiting to come face to face with a difficult situation. Here I’ll cover five more ways to make self-motivation easier: building up enthusiasm, being more mentally and physically prepared to face challenges, getting help from others, learning, and minimizing temptation.

Visualize and find your enthusiasm
When things are going well, I’m not distracted, and I have time to think about what I want to do, I’m often in a good state of mind to improve my motivation, but by definition these low-demand times tend to be ones when not much motivation is needed. I can build up motivation for harder times by using these opportunities to visualize where I’m trying to get and by otherwise spending time thinking about and especially enjoying my goal, whether I’m reflecting on successes so far, enjoying progress, envisioning future payoffs, or planning ahead. The more time I spend thinking positively about my goal, the more accessible positive thoughts about it will be when I really need them. For instance, if I’m trying to learn to play a musical instrument, I can visualize myself playing it and remind myself why I’m putting in all the hard work.

Take care of yourself
When we get enough sleep, exercise regularly, eat well, and use techniques like meditation to aid mood and mental focus, we’re much more capable of being proactive in our lives than when we are tired, inactive, badly nourished, overstuffed, or carrying around a lot of stress. Mood and physical well-being have an important impact on making good decisions, so everything we can do to improve them will tend to improve  motivation, too.

Get support
Connecting with a friend or family member to talk about your goals, the problems you’re running into, your plans, and your successes is a good way to keep your goal more in mind and to process your thoughts about it. Having someone in your corner can also make it more important to to do well and provides more options if something starts going wrong. A person trying to quit a bad habit can go talk to a supporter when temptation seems particularly strong. Someone trying to get a better job can talk through their plans and strategies if they have a sympathetic ear.

Read, learn
Reading about subjects having to do with our goals serves several purposes at once: it gives us more information to use when making plans; keeps our goal more in our mind; lets us try on others’ ideas; and serves as a physical reminder (whenever we see the book) of what’s being accomplished. Someone trying to get fit can learn a lot from books about nutrition and exercise, like The 9 Truths About Weight Loss. Anyone trying to change habits and running into emotional resistance can benefit from books like Emotional Alchemy, The Feeling Good Handbook, or A Guide to Rational Living.

Minimize temptation
Finally, minimizing temptation can be a real boon, at least in the short term, for anyone who’s really struggling with making the right choices. If you’re working on spending money wisely, you can take any savings you have and put it in a CD or some other instrument that makes it difficult or impossible to withdraw for a time. Someone who’s trying to quit playing video games can actually sell the games rather than hanging on to them to play just a little bit now and then.

This approach is a bit of a crutch, and the problem with relying too much on it is that when a situation comes up where there is temptation–for instance, when the person working on spending gets a tax refund, or when the former video game player is staying with a friend who has a top-notch video game system–the strategies to deal with the temptation may not be very well developed. But like all of these strategies, minimizing temptation–if not relied on absolutely–can help make everything simpler.

I’m continuing to enjoy reading Dr. Daniel Kirschenbaum’s The 9 Truths About Weight Loss, which contains a lot of very pointed and useful information about diet, exercise, and getting fit. Interestingly, it also points out some of the side benefits of these subjects, and in one place particularly, Kirschenbaum lists 50 meaningful benefits exercise provides, most of which have nothing to do with weight loss, and some of which have a lot to do with self-motivation.

I was already aware of most of these benefits, but it had never occurred to me to list out all the ones I knew, and the effect of Kirschenbaum doing so was impressive. Taking his list for inspiration, I’d like to point out 17 benefits of exercise on mood, motivation, and willpower, many of them paraphrased from Kirschenbaum’s list.

Regular exercise …

1. can provide an uninterrupted opportunity to think
2. relieves stress, while helping to prevent future stress
3. stimulates release of endorphins, brain chemicals that promote feelings of happiness and well-being (this is sometimes known as “runner’s high”)
4. improves social opportunities–and the people you meet when you exercise tend to be happier, better-balanced, more reliable, and more proactive people than the general population due to the effects of regular exercise in their lives
5. improves self-esteem, self-image, and confidence
6. promotes self-awareness if done without distractions
7. fights depression, both temporary and chronic
8. reduces anxiety
9. improves sleep, making you better-rested and more focused
10. contibutes to greater energy and alertness
11. increases endurance for non-exercise activities, both physical (for instance, housework) and mental
12. helps reduce pain and weakness that might otherwise get in the way of other activities
13. improves our ability to relax quickly
14. promotes clear thinking
15. improves willpower through practice
16. makes it possible to get a larger perspective on other parts of our lives
17. provides a model for self-improvement in other areas

Of course, exercise is also nearly indispensable if you’re seeking weight loss and has many non-weight-loss-related health benefits, such as lowering blood pressure and triglycerides, improving cardiovascular health, preventing problems with posture as we age, extending lifespan, lessening back pain, improving digestion, improving cholesterol levels, preventing osteoperosis, and many others.

As long as I’m plugging exercise, I’ll also mention that not only does strenuous exercise get progressively easier and more pleasurable as you go from trying it out to doing it regularly, but it also doesn’t even have to be strenuous to provide good effects. For example, both in terms of mood and weight loss (two of exercise’s greatest benefits) walking alone, done very regularly and preferably for at least 30 minutes at a time, can yield enormous returns.

The most impressive benefits of exercise start when you exercise at least 3 times a week for 30 minutes or longer each time, and they increase dramatically if you exercise every day or close to it (for aerobic exercise: strength exercise seems to work best if you give that a resting day between days you work out).

I’m working on expanding my list of books on the left to include some of the resources I haven’t yet reviewed on the site, and going forward I’ll be posting reviews of books I’ve read recently or some time ago, eventually linking to the reviews from the book list on the left. (The book reviews are in addition to my regular Monday, Wednesday, and Friday articles.)

John Medina’s book Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School is a fascinating read both for its content and because it is written about how we think and learn, so that it uses some of its own strategies to become more effective. For instance, Medina talks about how much more powerfully highly emotional situations imprint on our memories, and he uses several emotionally-charged situations in the book to illustrate his principles, helping make them more likely to sink in. As another example, he talks about the profound improvement we experience in learning when visuals are added to spoken or written words, and he helpfully supplies a very visual Web site, www.brainrules.net, to help underscore the points in his book.

Medina is a developmental molecular biologist who knows his stuff in great detail and isn’t shy about bringing in practical research from all quarters, which makes a much stronger case for the information he presents.

Several of his brain rules are extremely meaningful to our daily lives: the sections on exercise, short-term memory, sleep, and vision struck me particularly. Some of his other brain rules seem to be less profound and less useful, although there is some useful material in each of the twelve chapters.

Toward the end of each chapter, Medina offers ideas on how the information could be put into use. Unfortunately, he offers this information as a scientist does, coming up with hypotheses about what might work in classrooms or workplaces and suggesting that people try these things on a large scale to see how they work. That’s great, but it’s not much use to us in the trenches who are trying to find better ways to teach children or accomplish work or cooperate. I would rather he had focused on things that had already been tried and documented and pointed out where there were practices that could be adopted for definite gains. At least, though, there’s a chance that his suggestions for experiments will inspire other scientists to tackle those experiments, and if we’re lucky, Medina will follow up with another book.

I’ve been particularly looking forward to the sleep chapter in John Medina’s book Brain Rules (one of my current reading books) because I was interested to know once and for all how much sleep I needed. Was 8 hours really the magic number? What were the consequences of averaging, say, 7 hours, or 6? What about naps? I was interested in knowing how sleep affects our brains so that I could begin to see how it might affect self-motivation.

The answers were very helpful in some ways and completely unhelpful in others. What are the findings about how much sleep we need? Research so far seems to say that there is no definite number, and sleep needed varies widely from person to person. Some people (who have a condition called “healthy insomnia”) only need 4 or 5 hours a night and don’t seem to suffer any ill effects. Kids going through puberty definitely need more, preferably in the morning. There also seem to be genes that determine whether someone is a morning person (a “lark”), a night owl, or (like most of us) a “hummingbird,” which is to say someone with a “normal” sleep schedule. Sleep needs and daily schedules change as a person ages, too.

Too little sleep has serious costs
But one very clear finding across the board is that not getting enough sleep actively sabotages the brain’s abilities. As Medina puts it, “Sleep loss hurts attention, executive function, immediate memory, working memory, mood, quantitative skills, logical reasoning ability, general math knowledge … manual dexterity … and even gross motor movements.” Also, interrupted sleep or inadequate sleep severely limits our ability to remember things we learned that day, increases stress, and causes effects that mimic accelerated aging. Not getting enough sleep even forces the body to crave sugar while reducing our ability to make good use of sugar when we get it, playing havoc with healthy eating.

Figuring out your own sleep needs
Most of us already knew that shorting ourselves on sleep was bad (though maybe we didn’t realize it was that bad). But how do we figure out how much sleep do we actually need to not condemn ourselves to tired, inattentive, grumpy days? The best answer I can give is that we probably already know. If you wake up feeling overtired, it’s probably no secret to you that you could use more sleep. Some of us treat sleep as expendable if something else important is going on, but since even small sleep shortages can have a major impact on performance, we may be more effective if we get the right amount of sleep even though that takes away from the waking hours in which we can actually get things done. If you find yourself adding in extra “down time” during the day because you’re tired, or making mistakes, being distracted, or having trouble getting things done because of a sleep debt, then the “bonus time” you’re getting by cutting out sleep–and possibly more time besides–may be getting used up by the problems caused by not getting enough sleep. In other words, shorting ourselves on sleep is both unpleasant and unproductive.

The need for naps is built into our genetic code
Pretty much everyone, it turns out, is programmed to need about a half-hour nap in the early afternoon, although some of us need it more than others. This isn’t just an artifact of not getting enough sleep at night: it’s a normal part of the sleep-wake cycle in human beings. Many of us won’t have the option of getting this extra sleep on a regular basis, but it may be worth experimenting with it when you do have the freedom to try and seeing if it doesn’t give you a lot more energy and attention. In one study, pilots who took a 26-minute afternoon step performed 34% better than pilots who didn’t. That’s a big improvement!

At the very least, it’s best not to schedule things that require a lot of attention in the early afternoon if you can help it.

Sleep and self-motivation
How does this affect self-motivation? Pretty profoundly, it turns out. Self-motivation requires knowing what you need to do, paying attention to your priorities, devoting a little time and focus to moving forward, being self-aware, and solving problems that come up with your process. All of those things are compromised when we short ourselves even an hour or two of sleep a night. So with enough sleep, self-motivation will tend to get noticeably easier.

I know you will have gotten the advice to “get plenty of sleep” time and time again, and if you aren’t currently getting enough, it might be because you are trying to get enough time in the day to accomplish everything that’s important to you. Only you can judge whether or not a little sleep-deprivation is worth being less intelligent and less capable while the sleep debt lasts. In the past, at least, I’ve often gone with a little sleep deprivation in the service of what sometimes seems like a good cause. Put in this light, though, I’m not sure I want to continue to make that kind of a bargain. I’m beginning to think of it this way: if I can accomplish everything I already accomplish without always getting enough sleep, how much better could I do if I were actually operating at full capacity? It’ll be worth finding out.

By the way, if noise interferes with your sleep, or if you just want a little more silence in your life, you might want to try any brand of soft, foam earplugs with rounded ends (above). I’ve found these very helpful, especially for sleeping when someone else has to get up early, during travel, working while someone’s watching a TV or listening to music nearby, concentrating while my neighbor is mowing the lawn, etc. I haven’t been as happy with plastic earplugs or with the kind that are made of harder foam and don’t have a rounded end. Fortunately, the earplugs don’t block out sound completely, so it’s still possible to hear (faintly) a phone ringing or an alarm going off even while wearing them.
