Common Misconceptions About Sleep Hygiene

Last updated: February 2026

The most common misconception about sleep hygiene is that sleeping in on weekends can compensate for lack of sleep during the week.

Myth: Sleeping in on weekends can compensate for lack of sleep during the week.
Fact: The National Sleep Foundation states that sleeping in on weekends does not make up for sleep deprivation, as it disrupts the body's natural sleep-wake cycle, also known as the circadian rhythm (National Sleep Foundation).
Source of confusion: This myth persists due to the common media narrative that sleeping in is a way to "catch up" on sleep, which is often perpetuated by popular health and wellness blogs.

Myth: Drinking alcohol before bed helps with sleep.
Fact: The National Institute on Alcohol Abuse and Alcoholism reports that alcohol consumption before bed can disrupt sleep patterns and reduce sleep quality, as it increases sleep fragmentation (National Institute on Alcohol Abuse and Alcoholism).
Source of confusion: This myth persists due to the misconception that alcohol is a sleep aid, which may have originated from the fact that alcohol can induce relaxation and help individuals fall asleep faster, but ultimately leads to poor sleep quality.

Myth: Napping during the day can interfere with nighttime sleep.
Fact: A study by NASA found that napping can improve cognitive function and reduce sleep pressure, with the ideal nap duration being around 20-30 minutes to avoid entering deep sleep (NASA).
Source of confusion: This myth may have originated from the idea that napping can lead to sleep inertia, which is the feeling of grogginess upon waking from a nap, but this can be avoided by keeping naps short and scheduled at the right time.

Myth: Electronic devices before bed do not affect sleep.
Fact: The American Academy of Sleep Medicine reports that exposure to blue light from electronic devices before bed can suppress melatonin production, making it harder to fall asleep (American Academy of Sleep Medicine).
Source of confusion: This myth may have originated from the lack of awareness about the effects of blue light on the body's natural sleep-wake cycle, which is often not discussed in popular media.

Myth: Older adults need less sleep than younger adults.
Fact: The National Institute on Aging states that older adults still need 7-9 hours of sleep per night, as sleep needs do not decrease with age, but rather the ability to achieve restorative sleep may decline (National Institute on Aging).
Source of confusion: This myth may have originated from the observation that older adults often have different sleep patterns, such as waking up earlier, but this does not mean they need less sleep.

Myth: Sleep disorders are rare and only affect a small portion of the population.
Fact: The Centers for Disease Control and Prevention report that approximately 30% of the general population experiences insomnia, making it a common sleep disorder (Centers for Disease Control and Prevention).
Source of confusion: This myth may have originated from the lack of awareness about sleep disorders and their prevalence, which is often not discussed in public health campaigns.
