WHO KNEW?

People are funny, strange, and wondrous creatures! Just read on.

Hobbies

Estimates are that 400,000-500,000 people in the U.S,—more than 95% of them women—play Mah Jong with the National Mah Jong League card. Another 350,000,000 play thirteen versions of Mah Jong in Asia. Game experts have long recognized mah jong as the world’s most played game, with an estimated player base in Asia, Europe, and North American ten times bigger than poker. 

Who are the most optimistic pet owners in the U.S.? Tortoise owners, because tortoises can live 80-150 years! (I couldn’t find a number specifically for tortoise owners, but approximately 18% of American households keep tortoises or turtles as pets.)

Only 1-2% of the U.S. population has gone skydiving at least once.

Rock climbing? It depends on what type of climbing you are looking at. Women are 59% of sports climbers, but only 39% of those in mountaineering, ice, and traditional climbing combined. Then there is indoor vs. outdoor climbers, and boulderers, each of which have different gender makeups.

Among U.S. households, 52% have at least one person, age 5 or older, who is currently playing a musical instrument.  Two-thirds of Americans (66%) learned to play a musical instrument at some point in their lives.  The most popular musical instrument is the guitar.  The double bass is probably the least played instrument.

The average American spends only 19 minutes a day reading. The average number of books read by adults over the age of 65 is higher than any other age group, at around 20 books per year. Men tend to read non-fiction books more often than women.

Gender

Tiffany Hadish performing stand-up in 2013

Men tell more jokes professionally than women do. In the United States, 11.3% of stand up comedians are women and 88.7% of stand up comedians are men. Over an 11 year period, these percentages have shifted approximately 2% in favor of women. Systemic sexism in the industry (venue directors reluctant to book female comedians, backstage abuse, pay disparities, hostile crowds, etc.) are a bigger driver in this divide than any difference in innate funniness.

Being in love is biochemically the same as having a severe obsessive-compulsive disorder, according to researcher Dr. Donatella Marazziti.

Research on liking and loving between engaged couples found that the men loved their partners more than they liked them. The women both liked and loved their partners.

Equal numbers of males and females are conceived. Approximately 105 males are born for every 100 females.

Women survive famine and epidemics better than men. On the other hand, research has shown that women disproportionately suffer the impacts of disasters, severe weather events, and climate change.

One study found that men with longer ring fingers than index fingers had slightly longer penises. However, the common misconception that hand size predicts penis size has been widely discredited.

Research shows that women with larger breasts tend to have higher estrogen levels; breast size may therefore serve as an indicator of potential fertility.

Health

Approximately 60% of people are side sleepers. Only about 7% are stomach sleepers—which is fortunate, because stomach sleeping is the least healthful position.

Depth of sleep is related to brain waves. Convincing yourself you slept well can trick your brain into thinking it did.

A feel-good life is not necessarily a healthy one. Stress can be good for us. Stress is a powerful motivator. It can enhance your resilience and problem-solving skills, strengthen relationships, promote personal growth and self-improvement, and improve cognitive function.

Female pattern baldness affects about one-third of all women and people assigned female at birth (AFAB). The chances of getting female pattern baldness increase with age.

Caucasians experience the most hair loss; people of Afro-Caribbean heritage tend to experience the next highest levels of hair loss, with Asian men having the lowest hair loss rates.

On average, male pattern baldness begins in the late twenties to early thirties. By the age of 50, approximately 50% of men will experience some degree of hair loss.

For both men and women, pattern baldness tends to cluster in families. Having a close relative with patterned hair loss appears to be a risk factor for developing the condition.

Outlook

Nationally forty-seven percent of Americans are either very or somewhat optimistic, while the other 53 percent are more inclined to be somewhat or very pessimistic about the future.

Speaking in a foreign language might change your decisions or the reasons for those decisions.

In addition, speaking multiple languages gives a person a sense of reality and identity that is separate from monolinguals and monoculturals.

US research published in the Journal of Consumer Research indicates bilinguals may unconsciously switch personalities depending on the language they are using.

The type of music you listen to affects the way you perceive the world. According to results from a 2014 study done by Laura Getz and colleagues, those with a higher perceived idea of stress and those with higher optimism preferred more upbeat and popular music. Both also used this kind of music for emotional regulation.

Wisco and Nolen-Hoeksema (2009) found that those who were already unhappy had more negative memory associations [to songs] than those who were not unhappy.

90% of people text things they can’t say in person.

The food you make may not taste the same as the food someone else makes, despite following the same recipe. Minor differences in things like water hardness and oven temperature affect flavor, but the diner’s experience (happy or sad occasion, food presentation, level of hunger, speed of eating, etc.) also changes the taste of food.

Research indicates that those eating with others eat up to 48% more food than solo diners. This phenomenon is known as ‘social facilitation’.

People After Death

Barbara Kemmis, head of the Cremation Association of North America, says the cremation rate is almost 60 %, compared to 40% who opt for traditional casket burials.

Beyond urns, there are many options for ashes: made into jewelry, or different types of objects, such as  glass art, sculptures, diamonds, keychains, or hunting bullets. You can even turn your loved one’s ashes into a  vinyl album  or get them tattooed into your own skin.  Of course, many people choose to scatter cremains in special places. 

Bottom Line: Whatever you want to know about human behavior or characteristics, someone has studied it and shared those answers online.

TOO MUCH SLEEP

Is that even a thing? I asked myself that question after the night I slept more than eleven hours. First, I looked up what’s typical.

The Seven Sleepers, according to medieval Christian and Islamic legend, slept in a cave for 300 years to escape religious purges. (Illustration from the Menologian of Basil II)

Recommended Sleep by Age

The following table is from the CDC.

Age GroupAge RangeRecommended Hours of Sleep
Infant4-12 months12-16 hours (including naps)
Toddler1-2 years11-14 hours (including naps)
Preschool3-5 years10-13 hours (including naps)
School-Age6-12 years9-12 hours
Teen13-18 years8-10 hours
Adult18-60 years7 or more
61-64 years7-9 hours
65+ years7-8 hours

So, either I’m back to my middle school years, or I’m beyond the pale. No doubt the latter, but is that a bad thing?

Why Do People Sleep Too Much?

Reportedly, Albert Einstein regularly slept ten hours every night and napped frequently.

For people who suffer from hypersomnia, oversleeping is actually a medical disorder. The condition causes people to suffer from extreme
sleepiness throughout the day, which is not usually relieved by napping. It also causes them to sleep for unusually long periods of time at night. Many people with hypersomnia experience symptoms of anxiety, low energy, and memory problems as a result of their almost constant need for sleep.

Author Anne Rice suffered for years with obstructive sleep apnea, which may have inspired her interest and affinity in other creatures of the night, such as vampires.

Obstructive sleep apnea occurs when something blocks part or all of your upper airway while you sleep. Your diaphragm and chest muscles have to work harder to open your airway and pull air into your lungs. Your breath can become very shallow, or you may even stop breathing briefly. You usually start to breathe again with a loud gasp, snort, or body jerk. You may not sleep well, but you probably won’t even know that it’s happening. This condition can also lower the flow of oxygen to your organs and cause uneven heart rhythms.

Calvin Coolidge took a nap nearly every day in addition to sleeping ten or eleven hours every night.

Not everyone who oversleeps has a medical sleep disorder. Other possible causes of oversleeping include:

  • Alcohol
  • Prescription medications
  • Jet lag
  • Illness, such as a cold or flu
  • Extreme athletic exertion
  • Depression

Besides the conditions mentioned above, too much sleep — as well as not enough sleep — raises the risk of: heart disease, diabetes, depression, and obesity in adults age 45 and older. Any of these can carry an increased risk of death.

Sleeping Preference

Mariah Carey credits her fantastic singing voice to her habit of sleeping 15 hours every night.

And then there are people who simply want to sleep a lot. Individual sleep needs vary as widely as individual dietary needs, but “anything worth doing is worth overdoing” (as Mick Jagger, Ayn Rand, or possibly G. K. Chesterton famously said).

If long-term risks are too distant to motivate stopping, consider this: if you sleep more than you need to, you’re probably going to wake up from a later sleep cycle, meaning you’ll feel groggy and tired even though you’ve slept more. Research bears out the connection between too much sleep and too little energy.

LeBron James reports sleeping twelve hours a night for his best athletic performance.

According to Harvard Health, it appears that any significant deviation from normal sleep patterns can upset the body’s rhythms and increase daytime fatigue. The best solution is to figure out how many hours of sleep are right for you and then stick with it — even on weekends, vacations, and holidays.

The “Sleeping Beauty of Oknö” Karolina Olsson reportedly fell asleep in 1876, aged 14, and didn’t wake up until 1908, aged 46. (She may have been in a coma, kept unconscious by her parents, suffering from a head injury, or simply faking, but medical reporting in Sweden at the time never seemed to reach a definitive conclusion.)

How to Manage and Treat Chronic Oversleeping

After an overseer gave her a traumatic head injury, Harriet Tubman suffered from epilepsy and bouts of hypersomnia for the rest of her life.

But What If It’s Only Occasional?

During a golf tournament, Michelle Wie once slept more than sixteen hours. She regularly sleeps ten hours a night but prefers to get twelve hours or more.

According to the Cleveland Clinic, when you’re sleep drunk, your brain doesn’t make the transition to wakefulness. Your conscious mind isn’t fully awake, but your body can get up, walk, and talk. “People who have confusional arousal might act confused or have trouble speaking,” says Dr. Martinez-Gonzalez. “They might appear to be drunk, but they’re not.”

The CDC discusses sleep inertia. It is a temporary disorientation and decline in performance and/or mood after awakening from sleep.

People with sleep inertia can show slower reaction time, poorer short-term memory, and slower speeds of thinking, reasoning, remembering, and learning.

Bottom Line: Inviting as a warm bed can be on a winter night, as comfortable as it feels during a pounding rain, as luxurious as it can feel to just not get up, consider the price you may pay.

Robert Douglas Spadden (center) slept through the sinking of the Titanic when he was six years old. He woke briefly while being carried to a lifeboat, but his nurse told him they were going to look at the stars. So he went back to sleep.

NAPPING RIGHT

It’s human nature to have an energy slump in the afternoon, sometime between 1:00 and 4:00. It’s tied to our circadian rhythm. Two ways to combat midday fatigue: napping and exercising. This blog deals only with the former! (I’ve previously written about sleeping habits here.) On average, adults who nap do so 94.3 days each year.

Power Naps

In the 1990s, James Maas, a social psychologist and sleep expert coined the term power nap, 10 to 20 minutes long, to boost energy and alertness. A power nap is reputed to allow workers to get back to work right away because this amount of sleep does not yet reach the deeper states of a sleep cycle. The napper stays in the lighter stages of non-dreaming sleep. And for some, apparently, it works;  42.7% of U.S. full-time workers say they regularly nap during a break in a typical workday, 

Avoid 30-minute naps.

They cause “sleep inertia,” a groggy state that can last for another 30 minutes after waking up. This is because the body is forced awake right after beginning, but not completing, the deeper stages of sleep. 

A 60-minute nap might be okay.

Sleeping for 60 minutes includes the deepest type of sleep, slow-wave sleep. Because of this, the one-hour nap is ideal for helping an individual better remember faces, names, and facts. However, your brain will not complete a sleep cycle in only 60 minutes, so you may not be very alert for some time after waking up.

The ideal nap is 90-minutes.

This is the length of one full sleep cycle, which includes all the light and deep (REM and dreaming) stages of sleep. A full sleep cycle nap improves procedural and emotional memory (e.g. for playing musical instruments and driving). A 90-minute nap can also significantly boost one’s creativity. Because the nap is a full sleep cycle, waking up should come much easier. (This according to the National Sleep Foundation.)

Actually, the National Sleep Foundation recommends 20 or 90 minutes, but I prefer the latter!

On the other hand, the Mayo Clinic is very specific: the ideal nap occurs between 2pm and 3pm and lasts between 10 and 30 minutes. This takes advantage of one’s normal post-meal dip in energy and, if finished by 3pm, poses the least risk for causing sleeplessness at night.

Among older adults, shorter naps (less than 30 minutes) are reported by adults with better health; long naps (e.g., longer than 90 minutes) have been linked to cardiovascular problems and diabetes, declining cognitive function, and increased mortality.

Benefits of Napping

There are lots of benefits to sneaking in power naps every once in a while.

  • Curb the side effects of temporary sleep deprivation.  If you missed getting adequate sleep the night before, a quick nap can be restorative. 
    • Note: Temporary sleep deprivation refers to a night every once in a while in which you don’t get enough sleep.
  • Improve memory function and job performance.  Younger people definitely benefit from a quick nap in the afternoon, which can help them immensely with their studies, if they are in school. People of all ages can enhance job performance (and physical performance, in general) with a brief period of shut eye. If you feel sluggish while at work or in school, you may be able to improve the situation with a nap.
  • Lower blood pressure. 
  • Prevent mistakes in judgment or accidents while driving or operating machinery.  Drowsy driving is dangerous and can strike anybody at any time.
  • Heal the body. A brief nap can help relieve stress, allow the body to heal inflammation and injury, and improve mood.

Napping Can Be Problematic

  • If you have insomnia, you might exacerbate or even cause it by taking naps.  If you take long naps or nap  later in the afternoon, they may alter your circadian rhythms, leading to trouble with falling asleep at bedtime. On the other hand, people with severe insomnia might find themselves only ever able to take short naps, rather than sleeping all night.
  • If you have unidentified or poorly addressed sleep disorders—for example obstructive sleep apnea (OSA)—you will not cure it with naps. 
  • If you are diabetic, or likely to develop diabetes, note that recent research has linked long afternoon naps (over an hour) to Type II Diabetes. Observational studies of more than 300,000 people by the University of Tokyo found a link between long napping and a 45 percent increase in the incidence of diabetes when naps lasted at least 60 minutes.
  • If you don’t know what is causing your daytime fatigue, it might be better to avoid napping altogether.  Aside from sleep disorders, there’s a whole range of other causes, from prescription medications to underlying health problems to depression and mood disorders.

The prevalence of napping in older adults ranges from 20% to 60% in different studies, but is consistently reported to be higher than in other age groups. Age-related changes in circadian rhythm and sleep patterns, cultural beliefs, chronic conditions, medications, and lifestyle changes contribute to the high prevalence of napping in older adults.  

(FYI: If people lived alone in total dark, “days” would be about 25 hours each. However, our body clocks reset each day based on the sun’s light/dark cycles—plus alarm clocks, work schedules, and the world in general.) 

Bottom Line: Both short and long naps can increase alertness and be useful. Choose depending on personal rhythms, why you are napping, and environmental constraints.

BETTER KNOW YOUR CHARACTER: SLEEP

Even without pausing to think, people can easily describe their sleep habits. What does your character think and feel about about his or her own ? Is sleep a welcome respite or a necessary evil? What’s necessary for your character to fall asleep—and stay there? Is insomnia a chronic condition, or only within the plot situation? Does your character sleep as an escape mechanism? Does your character take sleep aids? Self-medicate with alcohol? Does sleep feel like a waste of time?

Deviating From Eight Hours

By now, pretty much everyone knows that, on average, people spend approximately one third of their lives sleeping. Anything that time-consuming must impinge on people’s (characters’) awareness.

It turns out most people sleep about 7 hours a night, so that would be “normal.” Fewer than 6 hours a night means one is a short sleeper, and more than 8 hours a night is a long sleeper. Does it matter?

People tend to perceive short sleepers as high-energy, productive, and on top of things. Long sleepers are often perceived as lazy, or at least not hard workers. 

What is your character’s sleep duration? Is s/he happy with with it? Smug? Defensive? Self-conscious?

Sleeping longer is better for physical health.  A study published in the American Journal of Epidemiology titled Sleep Duration and Survival Percentiles Across Categories of Physical Activity says sleep duration affects physical health: Those who get less than six hours of sleep are at increased risk of diabetes, hypertension, and early death even if they’re active and exercise regularly.

But can one sleep too much? Not if you maintain a reasonable level of physical activity. (Inactive long sleepers also die earlier, usually from cardiovascular problems.) 

Keep this in mind when creating realistic characters.

Early Birds vs. Night Owls

Early birds tend to get up early without setting an alarm, and even on the weekend.  Mornings are the most productive times. And activity trackers indicate that early birds actually move 60-90 more minutes per day. They fade in the evening, often in bed by 10:00.

There is a middle group: Day people sleep a little later and are most effective in the afternoon.

Night owls sleep as late as possible and are up well past nightfall, into the wee hours of the morning.  Night owls tend to sit more and move less, even when researchers factored for education and health conditions—so need to make an effort to move more for health reasons! And because this pattern doesn’t fit the world at large, making appointments for doctors, etc., can be problematic. Robo-calls while still in bed are especially annoying!

Stereotypes favor early risers for being healthy, wealthy, and wise. On the other time, creative types often report that their best work hours are evening/wee hours of the mornings.

NB: sleep patterns can change naturally over the lifespan. Infants sleep almost constantly; teenagers seem to sleep only while in a classroom setting.

What is your character’s sleep rhythm? Is it felt to be a blessing, a burden, or relatively irrelevant fact of life? Does s/he struggle against the “natural” rhythm? If so, why? Does your character push the limits for staying awake and then “catch-up” later?

Napping

Some people doze off while sitting in a chair; some settle into a recliner and nap intentionally; and yet others can only nap in their own beds, often with shoes off and tight clothes loosened. 

Some take “power naps” for 15 minutes or so during the work day; others nap for an hour or more at a time.

Napping offers several benefits for healthy adults, including

  • Relaxation
  • Reduced fatigue
  • Increased alertness
  • Improved mood
  • Extended functioning hours later
  • Improved performance, including quicker reaction time and better memory

Napping can also have negative effects, such as

  • Sleep inertia: feeling groggy and disoriented after waking up from a nap.
  • Nighttime sleep problems. 
    • Short naps generally don’t affect nighttime sleep quality.
    • People who experience insomnia or poor sleep quality at night, napping might worsen these problems. 
      • Insomniacs often have trouble napping at all because it takes longer to fall asleep than the allotted duration of the nap!

Does your character nap? Where? Why?  And is s/he okay with that?

Dreaming

Does your character claim not to dream? If so, s/he is mistaken. People team an average of 7 times a night during so-called REM sleep. These dream periods get longer as the night’s sleep progresses. Chances are, your dream denier simply doesn’t wake up within ten minutes of dreams ending.

Are dreams important to your character?  Some people mine dreams for clues to their inner lives, creative insight, and even hints of the future. Some people treasure dreams as raisers of awareness of non-conscious problems or conflicts. Some believe internal conflicts actually get solved during dreams. Some dreams are erotic and can lead to sexual release. And some people keep dream journals for later review and inspiration for creative works.

Like other dreams, nightmares often include elements of real life: anxiety, fears, failures, embarrassments, or trauma. People do not wake up happy from nightmares. Because nightmares are a disruption of the REM cycle rather than a part of it, a sleeper with nightmares wake up less refreshed than before. (Nightmares are not the same as night terrors.)

Lucid dreaming is less well-known than other sorts of dreams. According to Psychology Today, “During lucid dreaming, which most commonly occurs during late-stage REM sleep, a dreamer is aware that they’re asleep, but is able to control events within their dreams, to some extent.” Lucid dreamers report willing themselves to fly, fight, or act out sexual fantasies. There are communities dedicated to learning how to lucid dream at will, although evidence that this is possible remains inconclusive. Still, that doesn’t mean your character can’t be a dedicated lucid dreamer!

Research indicates that dreaming is crucial to intellectual functioning, memory consolidation, and mood regulation. A sleeper who is allowed to undergo every part of the REM cycle except dreaming will eventually develop the same problems as severe sleep deprivation, including hallucinations and strokes!

What is your character’s dream scape? Are dreams remembered? Are they amusing, irritating, or sources of unease? Does your character talk about his/her dreams? If so, to whom?

Bottom line: sleep—and everything associated with it—can make your plot richer and your character more realistic. 

A while back (March 10, 2020, to be exact) I wrote a blog Sleeping Alone and Together, about gender and personality reflected in sleep positions. 

MULTI-PURPOSE FURNITURE: BEDS!

Lectrology, the study of the bed and its associated surroundings, can be extremely useful and tell you a great deal about the owner, even if it’s only that they are a very knowing and savvy installations artist.”
from Unseen Academicals by Terry Pratchett

Well, yes, we all know about sex and sleep for energy recovery—separately or together, in no particular order! But for writing and/or personal reasons, think more broadly. What else happens in bed?

Plotting escape
  • Cuddling, before or after sex or on its own. One can actually hire a professional cuddler, female and/or male, paid by the hour for fully-clothed non-sexual cuddling.  
  • Getting/staying warm. Also think winter with no heat in the house.
    • In many parts of the world, it is customary for entire families to spend any free time in bed together, doing homework, making or repairing tools, or any other relatively stationary work, to conserve heat
  • Binge-watching TV (much more comfortable than on a sofa)
Escaping!
  • Getting sucked down the rabbit hole of YouTube
    • Or Tumblr, Cracked, Buzzfeed, Pinterest, etc.
  • Reading: books, magazines, newspapers, electronic devices
  • Eating and/or drinking
    • Sometimes this is just snacking, but on special occasions one may have a full meal delivered in bed
  • Working the Sunday Times crossword puzzle
Feeding your baby sister to the lions
  • Solving sudoku
    • Throwing the half-completed sudoku across the room when you realize there are two nines in the row
  • Playing a board game (carefully or with magnetic pieces)
  • Playing solitaire
  • Staring at the ceiling or into the dark and discuss serious issues with your bed partner
    • You can do this alone, but then it’s more of a monologue than discussion. 
      • Hearing a response to your monologue when you think you’re alone…!
Striking a pose
  • Indulging in catastrophic thinking about some personal issue, a family matter, and/or the future of humankind
    • What is the worst thing that could happen?
    • How could that come about?
    • And what might it lead to?
  • A refuge to escape an unpleasant task or situation by feigning illness
    • Often this is only a temporary fix, delaying the inevitable
Laying on the hard floor next to your bed without using it just to be stubborn
  • Recovering from an actual illness or injury
    • Applying ice or heat
    • Elevating a body part to reduce blood flow
    • Physical therapy exercises
  • Practicing modified choreography
  • Composing music
  • Cower with your head under the covers during a storm or earthquake
  • Playing with children or pets
Being the monster under the bed
  • Having a pillow fight
  • Jumping on the bed
  • Using bedding to stifle loud weeping, moaning, etc.
  • Toss, turn, and knot the bedclothes because you can’t get to sleep
    • Often with added frustration if someone is sleeping soundly beside you
  • Doing back exercises before getting up for the day
  • Nursing a hangover after being knee-walking drunk the night before
Yoga
  • Getting a massage: back, front, scalp, feet, calves, neck—whatever aches, feels good, or is your body-part fetish 
  • Sleeping excessively, possibly as a symptom of depression, illness, boredom, etc.
  • Thinking about plot points or themes for fiction and blog writing
    • In this instance, it helps to have a note pad and pen that light up when in use, or a device for dictating notes. Do not trust your memory!
  • Talking on the phone, usually for a l-o-n-g time
Levitating
  • Posting to Facebook, Twitter, or other social media
  • Sexting – NOT RECOMMENDED
  • Doing work/schoolwork, especially in the time of COVID
  • Getting bitten (bedbugs, spiders, humans. . .)
  • Deleting old emails, cleaning up the in box(es)
  • Mentally working out math problems and theorems using a base-6 rather than a base-10 number system

Bottom line: If you can imagine doing it in bed, you probably can—or can come up with a reasonable approximation.

Experiencing the outside world for the first time ever

EARLY BIRDS AND NIGHT OWLS

Folk wisdom would have us believe that we all should be early birds: they get the worm, after all, and they are healthy, wealthy, and wise. Indeed, research indicates that there are real differences between the early-to-bedders and the late-to-bedders.

.
.

Being up and ready for the day correlates with EBs getting better grades and having a better chance of getting a good “regular” job. 

More coffee, please!

In one way, at least, early birds (EBs) have a big advantage: most social life takes place during the day, and EBs can take full advantage of that. Getting to medical appointments, grocery stores, and business breakfasts are not hardships.

In addition, at least one study found that EBs anticipate problems and try to minimize them. Being proactive in this way is linked to better job performance, greater career success, and higher earnings. They set goals and plan to meet them.

Mixing coffee with beer makes it perfect for breakfast! Thanks, Coronado Brewing!

Overall, EBs are much more likely to exercise, and as a result are less prone to health problems, everything from obesity to depression. Perhaps that’s partly because most outdoor activity takes place during the day anyway!

However, not everything is roses for EBs. For one thing, their days are all downhill. They get no “second wind” late in the day. As sleepiness pulls, an EB’s performance lags. In addition, EBs need more sleep, and if they don’t get enough, it really drags them down.  Still, it seems a small price to pay for all the good stuff I just talked about.

So why wouldn’t everyone want to be an EB? First of all, what one wants isn’t always what one gets. People are biologically predisposed to be either an EB or a Night Owl (NO). Frederick Brown (Penn State psychologist) refers to EBs as early risers and NOs as late setters and comes out strongly on the side of genetic determination. In fact, in 2003, researchers discovered a “clock “ gene. EBs were more likely to have a longer version of this Period 3 gene.

And there is a real downside to being a NO—including being more prone to a whole host of mental and physical health problems, especially depression and obesity. Not surprisingly, they tend to die sooner than EBs.

Not bedtime. We’re not tired. Definitely not… tired…

Perhaps the increased likelihood of mental health issues are a byproduct of being generally and literally out of sync with society’s rhythms.

NOs struggle with social activities. Yes, there are all night restaurants,  gyms, and movies, but if NOs’ family and friends are on a different schedule, they face the choice of pressing/stressing themselves to accommodate or suffer from self-imposed isolation and loneliness.

It sounds like being a NO is a total bummer, but not so! Research has discovered several benefits to getting up with the owls.

Changing one’s sleep pattern often requires large amounts of caffeine.

Somewhat surprisingly (to me), NOs have more sex—which could lead to being productive in non-work-related ways! 

“It’s almost midnight. Let’s order pizza!”

One’s sleep patterns and preferences are expressions of one’s circadian rhythm: this is the rhythm of one’s body processes over the course of approximately 24 hours. In fact, the word “circadian” comes from the Latin words circā (approximately) and diēs (day). All living things—even plants—have them. (If there is life on Mars or Venus, then all bets are off!)

Left to their own devices (i.e., with no external cues as to time of day), humans tend to settle into a “natural” cycle of about 25 hours within a waking/sleeping day.

Fortunately, adjusting by an hour is fairly easy.

On the issue of enduring wake/sleep rhythms, there is lots of variability. Approximately 1% are diehard EBs and another 17% are diehard NOs, with everyone else being somewhere in between. The “tweeners” have an easier time making bigger adjustments in their sleep cycles.

It’s 2am. Time for everyone to wake up because I’m hungry!

There are age-clustering effects, too. High school and college age people, regardless of bio-rhythms, tend to stay up late and sleep in. The opposite is true of the elderly.

All sorts of outside factors have major chunks of control over when we wake and sleep, regardless of preferences. Many NOs must adapt to workplace schedules, or demands due to spouse or children. Consider how one’s body’s preferences would adapt to these work schedules.

  • 9-5:00ers
  • Night shift workers
  • Swing-shift workers
  • Parents
Sleep deprivation in fire fighters can be very dangerous. They get cranky when they’re tired.

People do what they have to do, sometimes for years at a time. Not surprisingly, swing-shift workers have the hardest time of it, and the more often their shifts change, the more disruptive it is. (If one’s work shifted by an hour a day, it would be easy to handle… but I don’t know of any examples.) If one works 7-3:00 followed by 3-11:00 followed by 11-7:00 and then repeats the cycle at lengthy intervals, the adaptation is easier than random shifts and/or short intervals.

At least the ambulances are pretty comfy for a nap.

Sleepers following a swing-shift work schedule face additional mental and physical hurdles. Researchers have identified a sleep disorder specific to employees on these schedules: Shift Work Sleep Disorder.

  • Prone to chronic sleep deprivation
  • Slower reaction time
  • Decreased focus
  • Impaired decision making

Many of the people whose jobs require focus, speed, high-level decision making, and operating under extreme stress also have to work on swing shift schedules.

Plus, hospitals are super creepy at night. So are power plants.

Whatever structures are imposed, our NO or EB tendencies endure, even into old age. Remove external structural constraints/demands and one’s true nature comes to the fore again.

Bottom line: You’ll be happier and perhaps healthier if you can shape your life to extract as many benefits as possible from your natural tendencies!

NIGHT TERRORS: MORE THAN DREAMS, MORE THAN NIGHTMARES

The Pooka (or Poukha or Puca), an Irish nightmare

A character’s “night life” can provide depth to the characterization and understanding for the reader. Nightmares and night terrors are both frightening, but the two sleep disorders are frightening in different ways to very different audiences. Knowing the distinctions will help you use them effectively in your writing.

Pity by William-Blake 1795

Adequate sleep, with all the different stages and cycles, is a crucial part of overall physical and mental well-being. Dreaming is absolutely necessary to good mental health. There is far too much detail to get into here, but research is clear. Indeed, repeatedly waking someone to prevent dreaming is a well-known form of torture.

What Are Nightmares?

Job’s Evil Dreams by William Blake

Nightmares are vividly realistic, disturbing dreams that rattle a person awake from a deep sleep. They often affect the body in the same way waking danger does. Adrenaline spikes, heart rate and respiration rate increase, and the body increases sweat production.

Nightmares tend to occur most often during rapid eye movement (REM) sleep, when most dreaming takes place. Because periods of REM sleep become progressively longer as the night progresses, people experience nightmares most often in the early morning hours.

A Dream of Crime & Punishment (1847) by JJ Grandville

Some people wake from nightmares crying, while others may wake shaking from fear. After a nightmare, people often have trouble falling back to sleep. The combination of the stress hormones flooding through the body with whatever lingering images from the nightmare are stuck in the mind make it very difficult to relax enough to fall back asleep. Particularly disturbing nightmares can cause sleep disruptions for days and stick around in the brain for years.

What are Night Terrors?

Night terrors are recurring nighttime episodes that happen while a person remains asleep. They’re also commonly known as sleep terrors. When a night terror begins, a sleeper will appear to wake up. They might call out, cry, move around, or show other signs of fear and agitation.

Other common reactions:

  • Screaming or crying 
  • Staring blankly
  • Flailing or thrashing in bed
  • Breathing rapidly 
  • Having an increased heart rate
  • Becoming flushed and sweaty
  • Seeming confused
  • Getting up, jumping on the bed, or running around the room
The Scream (1893) by Edvard Munch

A sleeper may become aggressive if a partner or family member tries to restrain them or keep them quiet. The episode can last for a few seconds or up to several minutes, though the sleeper typically doesn’t wake up. Most people fall right back to quiet sleep after a night terror.

Night terrors are more common in young children, but they can disturb adults as well. An estimated 2 percent of adults also experience night terrors. In reality, this number may be higher, since people often don’t remember having night terrors. 

Night terrors usually happen earlier in the night, during the first half of the sleeping period. This is when a sleeper is in stages 3 and 4 of non-rapid eye movement (NREM) sleep, also called slow-wave sleep. It’s uncommon to have them twice in one night, though it can happen. 

What is the Difference Between Night Terrors and Nightmares?

Night terrors may might seem similar to nightmares, but the two are different. In addition to the immediate mental and physical effects, the effect on witnesses or other members of a household are very different for night terrors and nightmares.

The Last Judgment (detail) by Jan van Eyck

When a sleeper wakes up from a nightmare, they will probably remember at least some of what the dream involved. Come morning, the sleeper is quite likely to remember the episode, though the memory may be vague.

During night terrors, the sleeper remains asleep and usually doesn’t remember what happened when they do wake up in the morning. The sleeper might remember a scene from a dream they had during the night terror episode, but it’s uncommon to recall any other part of the experience. 

The Orphans Dream (ca. 1900) by James Elliott

A partner, roommate, family member, or other witness to a night terror episode is likely to remember the experience quite well. The daughter of a friend has fairly frequent night terrors, during which she will wander out of the house in her pyjamas or physically attack her partner in his sleep. In the morning, she occasionally has grass on her feet or bruised knuckles but no memory of how she got them.

What Causes Sleep Disorders?

Many adults who experience nightmares or night terrors live with mood-related mental health conditions, such as depressionanxiety, or bipolar disorder.  Night terrors have also been associated with the experience of trauma and heavy or long-term stress

Physical factors can also contribute to the frequency of night terrors and nightmares. Sleep apnea is a very common cause of other sleep disorders. Some other possible causes

Frequent disruptions to sleep cycles (such as night terrors or nightmares) cause fatigue and, eventually, sleep deprivation. Fatigue and sleep deprivation increase the likelihood of having night terrors or nightmares. There’s no escape!

Nightmare (1810) by Jean Pierre Simon

Bottom Line for Writers: Characters can be just as interesting when they sleep! Why would your character have disrupted sleep, and how would they react? Would the sleep disruption be more effective if experienced by the narrator (nightmare or confusion after night terrors) or by someone close to the narrator (night terror or discussing remembered nightmare)?
