Myth or Fact: Sleep Edition

Let's separate sleep science from old wives' tales. Swipe through our quiz to test your knowledge.

Hitting the snooze button is harmless.

Myth!

Those extra few minutes of light, fragmented sleep can cause sleep inertia, leaving you feeling groggy for longer. It's better to set your alarm for when you actually need to wake up.

You can "catch up" on sleep over the weekend.

Myth!

While sleeping in can help reduce some sleep debt, it doesn't fully erase the negative effects of chronic sleep loss on your cognitive function and metabolism. Consistency is key.

Exercising at night will ruin your sleep.

Myth!

For most people, exercising in the evening is fine, as long as it's not an intense workout right before bed. A relaxing yoga session or a light jog can actually improve sleep quality.

Drinking alcohol before bed helps you sleep.

Myth!

While alcohol is a sedative that can help you fall asleep faster, it severely disrupts the second half of your sleep, suppressing REM sleep and leading to a less restorative night.

Your brain is resting while you sleep.

Myth!

Your brain is incredibly active during sleep, performing critical functions like memory consolidation, emotional regulation, and clearing out metabolic waste. It's resting from conscious thought, but it's hard at work.

A short power nap can boost your brainpower.

Fact!

A 20-30 minute nap can improve alertness, performance, and mood. It's the perfect length to get the benefits of light sleep without entering deep sleep, which can cause grogginess upon waking.

Older adults need significantly less sleep.

Myth!

Adults of all ages generally need 7-9 hours of sleep. While sleep patterns may change with age (becoming lighter and more fragmented), the total required amount doesn't drastically decrease.

Snoring is always a harmless annoyance.

Myth!

While occasional, light snoring can be harmless, loud and frequent snoring can be a primary symptom of obstructive sleep apnea, a serious condition that requires medical attention.

A warm bath before bed can help you sleep.

Fact!

It's not the warmth itself, but the subsequent cool-down. The rapid drop in body temperature after a warm bath mimics a natural sleep-inducing process, signaling to your brain it's time for rest.

You swallow an average of 8 spiders per year in your sleep.

Myth!

This is a widely circulated internet hoax. The vibrations of a sleeping, breathing human are terrifying to a spider. It's incredibly unlikely for one to willingly crawl into your mouth.

Your body is temporarily paralyzed during dreams.

Fact!

During REM sleep, the stage where most vivid dreams occur, your brain releases chemicals that cause temporary muscle paralysis (atonia). This is a protective measure to prevent you from physically acting out your dreams.

Watching TV in bed is a good way to wind down.

Myth!

Televisions and other screens emit blue light, which can suppress the production of melatonin, the hormone that controls your sleep-wake cycle, making it harder to fall asleep.

A colder room is better for sleeping.

Fact!

The ideal temperature for sleep is around 65°F (18.3°C). A cooler environment helps facilitate the natural drop in core body temperature that initiates and maintains sleep.

If you can't sleep, you should stay in bed and try harder.

Myth!

This can create a stressful association between your bed and wakefulness. If you can't sleep after 20 minutes, get up, go to another room, and do something relaxing until you feel sleepy again.

The full moon can disrupt your sleep.

Fact!

Studies have shown that even in controlled lab settings with no windows, people tend to have less deep sleep and take longer to fall asleep during the full moon phase, suggesting an internal biological rhythm tied to lunar cycles.

Losing just one hour of sleep doesn't affect you.

Myth!

Even a small amount of sleep debt can significantly impair your focus, judgment, and reaction time the next day. The effect is cumulative and you may not even notice the decline in performance.

A firm mattress is always better for your back.

Myth!

The best mattress depends on your body type and sleep position. A mattress that is too firm can create pressure points, while one that is too soft won't provide enough support. A medium-firm mattress is often the best for most people.

You are taller in the morning than at night.

Fact!

Throughout the day, gravity compresses the cartilage in your spine. When you sleep, your spine decompresses, and you can be up to half an inch taller when you wake up.

Cheese before bed gives you nightmares.

Myth!

There's no scientific evidence for this. Any vivid dreams after eating a large, rich meal (like cheese) are more likely due to indigestion or a higher body temperature, which can disrupt sleep patterns.

Yawning means you are tired.

Myth! (Partially)

While it is associated with tiredness, the primary function of yawning is believed to be thermoregulation—it helps cool down an overheating brain to keep it working at optimal efficiency.

Insomnia is just difficulty falling asleep.

Myth!

Insomnia also includes difficulty staying asleep (waking up frequently) and waking up too early and not being able to get back to sleep. It's a disorder of sleep maintenance, not just sleep onset.

Your body can fully adapt to shift work.

Myth!

Our internal body clocks (circadian rhythms) are strongly tied to the natural light-dark cycle. While some adaptation is possible, most shift workers' bodies never fully adjust, leading to a higher risk of health problems.

Sleep-talking happens during dreams.

Myth!

Sleep-talking (somniloquy) can occur during any stage of sleep, but it is most common and understandable during the lighter stages of non-REM sleep, not during the deep dreaming of REM sleep.

Some people genuinely need only 4-5 hours of sleep.

Fact! (But it's rare)

A very small percentage of the population (less than 1%) has a genetic mutation that allows them to thrive on significantly less sleep without any negative side effects. For everyone else, 7-9 hours is essential.

A messy bedroom can negatively impact your sleep.

Fact!

Clutter can increase stress and anxiety, making it harder for your brain to switch off and relax. A clean, organized bedroom promotes a sense of calm and is a key part of good sleep hygiene.

It's better to have two pillows than one.

Myth!

The goal is to have one pillow of the correct height (loft) to maintain a neutral spine. Stacking two pillows often creates an unstable surface and an improper angle for your neck, leading to pain.

Pressing your face into a pillow can cause wrinkles.

Fact!

Repeatedly compressing and creasing your skin against a pillow, especially a cotton one, can contribute to the formation of "sleep lines" which can become permanent wrinkles over time. Silk or satin pillowcases can help reduce this friction.

Counting sheep is an effective way to fall asleep.

Myth!

A study from Oxford University found that counting sheep is actually too boring and simple to distract a worried mind. Visualizing a relaxing scene, like a beach or a forest, was found to be much more effective.

You can learn a new language by listening to it in your sleep.

Myth!

While some studies show the brain can process simple sounds and reinforce existing memories during sleep, there is no evidence that you can learn complex new information, like a language, from scratch while unconscious.

Dreams last for only a few seconds.

Myth!

Dreams can last anywhere from a few minutes to over half an hour, and you typically have multiple dreams each night. They tend to get longer as the night progresses, with the longest occurring in the morning.

Sleep Hygiene Essentials

Building healthy sleep habits is a cornerstone of wellness. Here are answers to some common questions about creating a routine that promotes consistent, high-quality rest.

Most sleep experts agree that the optimal temperature for sleep is surprisingly cool: around 65 degrees Fahrenheit (18.3 degrees Celsius). Your body's core temperature naturally drops as you fall asleep, and a cool room helps facilitate this process, signaling to your body that it's time to rest. A room that is too hot can interfere with REM and slow-wave sleep, the most restorative stages.

For darkness, invest in high-quality blackout curtains or blinds. Even small amounts of light from streetlamps or electronics can disrupt melatonin production. Cover or remove any electronics with LED lights. For noise, a white noise machine or a simple fan can be incredibly effective at masking disruptive sounds like traffic or neighbors. Earplugs are also a simple, low-cost solution.

A large, heavy meal right before bed can lead to indigestion and heartburn, which can disrupt sleep. However, going to bed hungry can also keep you awake. The best approach is to have your last large meal 2-3 hours before bed. If you're hungry later, a small, light snack rich in tryptophan and carbohydrates (like a small bowl of oatmeal or a banana) can actually promote sleep.

Yes, it's arguably more important than a consistent bedtime. Waking up at the same time every day, even on weekends, helps to regulate your body's internal clock, or circadian rhythm. This makes it easier to fall asleep at night and wake up naturally in the morning. Sleeping in on weekends can create a "social jetlag" that makes it much harder to wake up on Monday morning.

If you're still awake after 20-30 minutes, don't just lie there feeling frustrated. This can create a negative association between your bed and wakefulness. Get out of bed and go to another dimly lit room. Do something calming, like reading a book (not on a screen), listening to soft music, or meditating. Return to bed only when you feel sleepy again.
