Your body gets use to getting less sleep.

• True

• False

Answer explanation

Research has found that a lack of sleep takes a toll over both the short- and long-term, demonstrating that your brain and body can’t just get used to getting less sleep.

How Long You Sleep Is NOT All That Matters

• True

• False

Answer explanation

Sleep duration is important, but it’s not the end-all, be-all. Sleep quality is another critical factor to consider, and it is closely connected with sleep continuity and avoiding sleep disruptions.

A Good Sleeper Doesn’t Move at Night

• True

• False

Answer explanation

Minor movements of the body can occur during normal, healthy sleep. Movements during sleep are generally only a concern if they are one or more of the following:

Prolonged or chronic

Abnormal (such as sleepwalking)

Aggressive or violent

Bothersome to a bed partner

Causing nighttime awakenings

Dreaming Only Happens During REM Sleep

• True

• False

Answer explanation

The most intense dreams usually happen during REM sleep, but dreaming can occur during any sleep stage.

Dreams in REM and non-REM sleep usually have different content with more vivid or bizarre dreams usually taking place during REM stages.

Snoring Is Harmful and You Can Do Something To Fix It.

• True

• False

Answer explanation

Light, occasional snoring usually isn’t a problem, but loud and frequent snoring is often a cause for concern.

Chronic or loud snoring may be caused by obstructive sleep apnea (OSA), a serious breathing disorder that fragments sleep and prevents a person from taking in the oxygen their body needs.

Exercising at Night Disturbs Sleep

• True

• False

Answer explanation

Data from surveys and research studies indicates that even vigorous exercise at night does not usually affect sleep. In fact, working out at night helps many people sleep better.

Napping Does Not Make up for Lack of Sleep at Night

• True

• False

Answer explanation

While a quick nap can provide a boost of energy, it’s not a substitute for quality sleep at night, especially because it doesn’t involve moving through the stages of sleep in the same way as during nightly sleep.

A Warmer Bedroom Is Best For Sleeping

• True

• False

Answer explanation

Although a warm bedroom might feel cozier, studies indicate that it’s not ideal for sleep. Body temperature drops naturally as part of the physical process of sleep, and a bedroom that’s too hot may disrupt that process.

If You Can’t Sleep, It’s Best To Leave Your Bed Until You Fall Back Asleep

• True

• False

Answer explanation

Sleep experts recommend getting out of bed if you can’t fall asleep within 20 minutes. Instead of tossing and turning in bed, it’s better to get up, do something relaxing in a quiet and dim setting (without using your cell phone or other electronic devices), and then try to go back to bed.

Hitting Snooze Provides Meaningful Extra Rest

• True

• False

Answer explanation

The Snooze bar can provide what seems like precious minutes to keep sleeping between alarms, but this time is unlikely to offer meaningful rest. Fragmented sleep is generally not restorative, so you shouldn’t count on hitting snooze to help you wake up more refreshed.
