When it comes to sleep, everyone has their own ideas on how to get a good night’s rest. Some people swear by drinking a glass of milk, while others say you should never eat cheese before bedtime. How can you separate fact from fiction? We delved into six common sleep myths, and now we’re here to tell you why they’re flat-out wrong.
Myth #1: Everyone needs 8 hours of sleep
Reality: The amount of sleep someone needs depends on a variety of factors, including genetics. “Sleep need is like height, we are all different and how much we need is to a large degree, genetically determined,” sleep expert Dr Neil Stanley explained to The Independent. Tracking your bed time, how many hours you sleep a night, and how well rested you feel each day can help you find the ideal amount of sleep for your body, according to sleep experts at Harvard.
Myth #2: Drinking warm milk makes you fall asleep
Reality: Drinking milk to go to sleep is such a popular theory, it’s been featured everywhere from dairy commercials to Happy Gilmore.
However, there’s no scientific evidence that drinking milk will help you sleep, according to the University of Arkansas. As the university explains in a blog post, the myth began because milk has small traces of tryptophan, an amino acid used to make the hormones serotonin and melatonin in our bodies, which do help us sleep. However, there’s not nearly enough tryptophan in milk to make anyone drowsy.
Myth #3: Napping makes it hard to sleep at night
Reality: Some believe napping is bad for bed time, but a quick afternoon rest won’t disrupt your ability to go to bed, according to the American National Sleep Foundation. In fact, our internal clocks are programmed to make us sleepy in the afternoon. A short 20-minute nap is best so you don’t enter a REM, or a deeper stage of sleep, as this will only make you tired later in the day.

Myth #4: Cheese causes nightmares
Reality: Although people often blame cheese for their bad dreams, nutritionist Joy Dubost, previously told MensHealth.com there is no evidence to support this idea.
Researchers believe people who are sensitive to lactose may have trouble sleeping if they consume dairy before bed due to gas, bloating or cramps – but not due to nightmares.
Myth #5: Sleepiness is caused by the number of hours you sleep each night
Reality: It’s entirely possible to sleep for eight or nine hours a night and still feel fatigued if you suffer from sleep apnea. People with the condition stop breathing while they sleep, which causes them to repeatedly wake up throughout the night. This makes it hard to sleep deeply, which causes daytime sleepiness.
Myth #6: Only some people dream at night
Reality: Researchers say that everybody dreams each night. In fact, the average person will dream four to six times per night when they enter REM sleep, according to the National Sleep Foundation.
People who think they don’t dream simply don’t remember, and scientists aren’t sure why some are able to recall their dreams better than others.
