14 Common Myths About Sleep Marylanders Have That Science Has Debunked

Marylanders love their sleep, but we don’t always get the facts right. Old advice, viral “hacks,” and half-remembered tips have turned into stubborn myths that just won’t die.

The truth is, sleep science has come a long way, and much of what people still believe is outdated or flat-out wrong.

Here are some of the most common myths about sleep, and what research actually says.

“You can catch up on sleep over the weekend”

Plenty of people push through busy workweeks believing they can fix everything with a Saturday sleep-in.

Unfortunately, research on weekend recovery sleep shows it doesn’t fully make up for lost rest.

Sleeping in may temporarily reduce sleepiness, but it doesn’t restore cognitive performance or metabolic functions disrupted by chronic deprivation. Your body clock doesn’t just reset because you spent Sunday under the covers.

Even short-term sleep debt can throw off hormone regulation, mood stability, and alertness.

While one long night can help a little, the effects of weekday short-sleeping linger longer than most people think.

Consistent nightly schedules beat weekend marathons every time.

“Some people only need four or five hours of sleep”

You’ve probably heard someone brag, “I function fine on five hours.” While there are rare genetic outliers, sleep duration studies show most adults need seven to nine hours for optimal health.

People who regularly sleep less often don’t realize how impaired they are because their brains adjust to a lower baseline.

Reaction times, memory recall, and emotional regulation quietly decline even if you “feel” okay.

Chronic short sleepers face higher risks of obesity, cardiovascular disease, and impaired immune function. Over time, these effects compound in ways you can’t simply “willpower” away.

So unless you have a specific gene mutation (which is extremely rare), skimping on sleep is a slow burn, not a superpower.

“If you wake up during the night, you’re a bad sleeper”

Middle-of-the-night wakeups can feel frustrating, but research shows they’re perfectly normal. Human sleep naturally moves through cycles of lighter and deeper stages, and brief awakenings often happen between them.

Most people forget these micro-arousals by morning, but waking long enough to check the clock can create unnecessary stress.

That stress, ironically, makes it harder to fall back asleep.

Historically, segmented sleep was even common; people had a “first sleep” and “second sleep,” with a period of quiet wakefulness in between.

The idea that perfect sleep means eight uninterrupted hours is more modern than we realize.

Instead of panicking at 3 a.m., focus on calming your mind and letting the next cycle resume naturally.

“Older adults need less sleep”

It’s easy to assume older adults simply need fewer hours, but age-related sleep research paints a different picture. Sleep patterns do change with age, more fragmented, lighter, and earlier, but total sleep need remains about the same.

What often decreases is sleep quality, not the body’s requirement for restoration.

Medical conditions, medications, and changes in circadian rhythms can make it harder to get those hours in a single stretch.

Many older adults also nap more, which can help compensate but sometimes interferes with nighttime rest if poorly timed.

Supporting good sleep hygiene, like consistent schedules and limiting late caffeine, matters at every age, not just for the young.

“A nightcap helps you sleep better”

That glass of wine might make you drowsy, but alcohol’s impact on sleep is more disruptive than relaxing.

Alcohol reduces the time it takes to fall asleep, but it fragments later sleep stages and suppresses REM, the stage linked to memory and emotional processing.

As the body metabolizes alcohol overnight, people experience more awakenings, lighter sleep, and sometimes night sweats or heart palpitations.

Even small amounts can alter the architecture of your rest, leading to groggier mornings despite “falling asleep fast.”

So while the nightcap may seem like a shortcut, it’s a tradeoff that ultimately leaves your brain less refreshed.

“Lying in bed with your eyes closed is almost as good as sleeping”

It sounds logical, but studies on quiet wakefulness reveal that rest without sleep doesn’t trigger the same restorative processes.

Hormone regulation, synaptic pruning, and tissue repair all rely on actual sleep stages, not just stillness.

You might feel physically relaxed lying there, but your brain isn’t performing the deep maintenance that happens during slow-wave and REM sleep.

This misconception often leads people with insomnia to underestimate their sleep needs or accept insufficient rest as “good enough.”

Quiet time can help you wind down, but it’s no substitute for the real thing.

“Hitting snooze gives you a little more rest”

That extra nine minutes may feel luxurious, but research shows it doesn’t provide meaningful rest.

Once the alarm goes off, your body begins the wake-up process, releasing cortisol and increasing heart rate.

Falling back into a light doze after that doesn’t restore energy. It just fragments the transition, leaving many people feeling groggier thanks to sleep inertia.

Repeated snoozing can also condition your brain to associate the alarm with “not time to get up yet,” which makes future mornings harder.

A single, well-timed alarm is more effective than hitting snooze three times and stumbling out the door half-awake.

“Exercising at night ruins your sleep”

This myth persists even though evening exercise studies don’t support it for most people.

Moderate to vigorous activity in the evening doesn’t necessarily delay sleep onset or reduce quality, unless it’s extremely intense and finished minutes before bed.

For many, nighttime workouts actually improve sleep by reducing stress and promoting temperature regulation, both of which encourage deeper rest.

The key factor is timing. Giving your body at least an hour or two to cool down afterward makes a difference, as does avoiding excessive caffeine late in the day.

So if your schedule only allows for evening runs or gym sessions, don’t stress, it’s more about how than when.

“Blue light is the only thing messing with your sleep”

It’s true that blue light exposure can delay melatonin release, but it’s not the sole culprit behind modern sleep issues.

Psychological stimulation from doom-scrolling, late-night emails, or binge-watching also keeps the brain alert well past bedtime.

Environmental factors like room temperature, noise, and inconsistent schedules can have just as much impact. Blaming blue light alone oversimplifies a complex picture.

Using warm light settings and screen filters helps, but pairing that with intentional “wind-down” routines is even more powerful.

Blue light matters, but it’s part of a larger nighttime ecosystem you can shape to your advantage.

“Everyone should get eight hours exactly”

The “eight-hour rule” is easy to remember, but research shows it’s more of an average than a prescription. Individual needs vary based on genetics, age, activity levels, and health.

Some adults thrive at just under seven hours, while others feel best closer to nine.

Fixating on hitting eight exactly can create unnecessary anxiety if you naturally fall outside that range.

What matters more is how you feel during the day: consistent alertness, stable mood, and minimal reliance on caffeine are better indicators of good rest.

Think of eight hours as a ballpark, not a rigid target.

“Napping is lazy and ruins your nighttime sleep”

Short naps can actually be powerful. Studies on strategic napping show that 10–30 minute naps improve alertness, memory, and mood without causing the grogginess that longer naps often bring.

The trick is timing. Early afternoon naps align with natural circadian dips, while late-afternoon snoozes can interfere with falling asleep at night.

Napping isn’t a sign of laziness, it’s a tool. Many cultures have long built daily rest periods into their routines with positive results.

If you keep naps brief and well-timed, they can complement, not compete with, your nighttime sleep.

“If you can’t sleep, just stay in bed and wait”

Lying awake for long stretches trains your brain to associate the bed with wakefulness.

Research shows that getting up after 15–20 minutes and doing a quiet, low-light activity is more effective than stubbornly waiting.

This breaks the mental loop of frustration and helps your body naturally cue the next sleep cycle.

Many people who try this are surprised how often they become drowsy again once they remove the pressure to “force” sleep.

The bed should be a cue for rest, not wrestling with your thoughts.

“More sleep is always better”

It’s easy to assume that if seven hours is good, ten must be great.

But research shows that regularly sleeping more than nine or ten hours is associated with increased risks of headaches, fatigue, metabolic issues, and even cardiovascular problems.

Long sleep duration is often a sign of underlying health concerns like sleep apnea, depression, or chronic illness, not a cause of extra vitality.

Occasional long nights after deprivation are fine, but making marathon sleep a habit can signal that something else is off.

More isn’t always better; balance and regularity matter far more than sheer quantity.

“You should stay in bed until you fall asleep no matter how long it takes”

This advice sounds logical but backfires. Behavioral insomnia research shows that lying awake for prolonged periods conditions your brain to associate the bed with wakefulness.

Instead, experts recommend the “15–20 minute rule”: if you can’t sleep, get up and do something quiet and low-light until you feel drowsy again.

This technique is a cornerstone of cognitive behavioral therapy for insomnia (CBT-I), one of the most effective non-drug treatments for chronic sleep issues.
