Sleep Fact or Myth

With so much information online, it can be hard to separate genuine sleep advice from well-worn myths. Does cheese really give you nightmares? Is eight hours of sleep a hard rule? And can you catch up on lost sleep at the weekend?

❌ MYTH: Power naps are always good for you

✔ FACT: Daytime naps can actually disrupt your night-time sleep.

Many people experience a natural dip in alertness during the afternoon, which can make a nap feel tempting. While short naps of 15–20 minutes can be helpful in safety-critical jobs (such as driving), longer naps may push you into deeper sleep stages. This often leads to grogginess and can interfere with your ability to fall asleep later that evening.

❌ MYTH: Sleep before midnight is better than sleep after midnight

✔ FACT: Sleep is sleep - quality and consistency matter most.

The idea that “hours before midnight count more” is a common misconception. What’s more important is getting enough sleep overall and keeping a consistent routine. Whether you go to bed at 10pm or midnight, your body benefits most from regular sleep patterns.

❌ MYTH: Once a light sleeper, always a light sleeper

✔ FACT: While sleep type varies, habits and environment can improve sleep quality.

You may not be able to instantly change how deeply you sleep, but lifestyle adjustments can help. Reducing screen time before bed, improving your sleep environment, exercising regularly and watching your diet can all contribute to longer, more restorative sleep.

❌ MYTH: Eating cheese before bed gives you nightmares

✔ FACT: There’s no solid evidence linking cheese to nightmares.

While cheese itself hasn’t been proven to cause bad dreams, eating late at night can affect digestion. Digestive discomfort may make it harder to fall asleep or cause restless sleep. If you’re hungry before bed, opt for lighter foods such as bananas, which contain magnesium and potassium — natural muscle relaxants.

❌ MYTH: You only yawn because you’re tired

✔ FACT: Yawning can happen for many reasons.

We yawn when we’re tired, bored, waking up and even when we see someone else yawn. This phenomenon, known as contagious yawning, is thought to be linked to social or neurological responses rather than tiredness alone.

❌ MYTH: You can catch up on sleep at the weekend

✔ FACT: Consistency is key for healthy sleep.

Sleeping in at weekends can disrupt your body clock, making weekday mornings harder. While catching up on a small amount of lost sleep may help short-term fatigue, regularly relying on weekend lie-ins can worsen long-term sleep patterns.

❌ MYTH: Sleeping pills guarantee better sleep

✔ FACT: Sleeping pills don’t always provide natural, restorative sleep.

Although they may seem like a quick fix, many sleep experts warn that sleep induced by medication is not the same as natural sleep. Long-term use has been linked to side effects such as memory issues and “rebound insomnia,” where sleep problems return  sometimes worse than before.

The Takeaway

Good sleep isn’t about hacks or rigid rules it’s about creating the right environment, routine, habits and of course a really supportive bed. Understanding the facts behind common sleep myths can help you make better choices for your wellbeing and enjoy more restful nights.
