TOO MUCH SLEEP

Posted on by vlaw759

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.

BETTER KNOW YOUR CHARACTER: SLEEP

Posted on by vlaw759

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. 

EARLY BIRDS AND NIGHT OWLS

Posted on by vlaw759

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.
  • Power plant operators
  • Emergency medical technicians and paramedics
  • Doctors and nurses
    • Emergency room staffers and residents are more likely to work night shifts and swing shifts
  • Emergency hotline operators (911)
  • Police
  • Military personnel

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.

Well, now I’m just confused.
Should I obey R.L. Stine or David Byrne?

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!
