Common Sleep Myths Debunked

Sleep is essential for our health and well-being, but there are many myths and misconceptions about sleep that can affect our sleep quality and quantity. Some of these myths are based on outdated or inaccurate information, while others are influenced by cultural or personal beliefs. In this blog post, we will debunk some of the most common sleep myths and explain the scientific facts behind them.

Myth: Cheese gives you nightmares

Some people believe that eating cheese before bed can cause nightmares or vivid dreams, but there is no evidence to support this claim. According to a 2015 review of studies published in the journal Frontiers in Psychology, disturbing or vivid dreams were more associated with emotional eating, uncontrolled eating and dieting rather than what was eaten. However, late-night eating can lead to disrupted sleep, according to a study published in 2019 in the journal Molecular Nutrition and Food Research. This is because the body’s circadian rhythm — the internal clock that regulates the body’s sleep-wake cycle — is thrown out of whack as the body works hard to digest food, disrupting natural sleep patterns.

Therefore, if you want to avoid nightmares or vivid dreams, it might be better to avoid eating cheese or any other food close to bedtime. Instead, you should follow good sleep hygiene practices, such as sticking to a regular sleep schedule, avoiding caffeine and alcohol before bed, creating a comfortable and dark sleeping environment, and relaxing before going to sleep.

Myth: Alcohol helps you sleep better

Alcohol may have a sedative effect that helps you fall asleep faster, but it does not improve your sleep quality or duration. In fact, alcohol can have negative effects on your sleep by reducing REM sleep, which is vital for memory and emotional processing. REM sleep usually starts about 90 minutes after falling asleep and continues until morning. If you start to rack up a REM sleep debt, you might struggle to concentrate, learn and lay down long-term memories.

Alcohol can also increase the risk of snoring and sleep apnea, which are conditions that cause pauses in breathing or shallow breathing during sleep. This can lead to further sleep disturbance and poor oxygen levels in the blood. Moreover, alcohol can disrupt your circadian rhythm by affecting your melatonin production, which is a hormone that regulates your sleep-wake cycle.

Therefore, if you want to improve your sleep quality and duration, it might be better to avoid drinking alcohol before bed. Instead, you should drink plenty of water throughout the day, exercise regularly during the day but not too close to bedtime, and practice relaxation techniques such as meditation or yoga before going to bed.

Myth: A warm bedroom temperature is best for sleeping

Some people believe that sleeping in a warm bedroom temperature can help them fall asleep faster and stay asleep longer. However, this may not be true for everyone. According to a 2018 study published in the journal Sleep Medicine, different people have different preferences for their bedroom temperature depending on their age group. For example:

  • Young adults (18-25 years old) prefer cooler temperatures (around 18°C or 64°F) than older adults (over 65 years old).
  • Older adults prefer warmer temperatures (around 24°C or 75°F) than young adults.
  • Women tend to prefer cooler temperatures than men.
  • People who live in colder climates tend to prefer cooler temperatures than people who live in warmer climates.

Therefore, if you want to find out what temperature works best for you when sleeping in your bedroom, you might want to experiment with different settings until you find one that suits your comfort level and preference.
