Learn a new language……in your sleep!

Whether you’re forced to take a French class to fulfill school credits or you’re teaching yourself Japanese because you love the culture so much that you want to speak it, learning a new language is not easy. It is a slow process and is a lot of work as it requires daily practice to learn a new language. But what if you could also learn it in your sleep? Did you know sleeping can help you learn a foreign language?

How can this possibly work?

Your brain does not sleep with you. While you’re sleeping, your brain is making many new connections with neurons, which are nerve cells in the brain. And during undisturbed deep sleep, your brain cells alternatively go into an active state called “up-state” and an inactive state called “down-state” about every half-second. This is where your brain is replaying the events and learnings of the day, a process called “consolidation”.

Obviously, this is not saying that you can play a language CD while asleep and then wake up to be suddenly fluent. But rather, if you are learning a new language at school or for fun, and you additionally play the language during your sleep, you’ll find it’s like magic how much better your memory is on what you have just learned. The practice of listening to the new foreign language while sleeping boosts and strengthens the consolidation process in the brain.

Has this worked before on people?

Studies, such as Swiss biopsychologist Björn Rasch’s, have been conducted where students were played new foreign vocabulary in their sleep and compared their memory of it with students who were played the same words while they were awake. Results showed that the students who listened to the new-language vocabulary while asleep recalled them better on a test than the ones who listened while awake.

Another study that focused on word-learning and napping in children where they similarly let them hear new words and then sleep shortly after, resulted in them remembering the newly gained knowledge significantly better than the children who stayed awake.

The importance of sleep

As explained earlier, you cannot entirely learn a new language in your sleep, but sleep can help enforce your learning a great deal! Getting adequate and quality sleep is so important, not just for learning a new language, but for your general health and basic survival as well. It is always worth getting a decent sleep every night instead of allowing yourself to become sleep-deprived. If getting enough sleep is something that seems difficult for you, it is never a bad idea to consider some healthy sleeping tips.

Happy sleeping and happy learning!

What is sleepwalking?

One night, my high school roommate suddenly said: “Let’s go for a barbeque.” I was surprised and I said to him” Are you mad?” He replied to me” No, I am not.” However, I found that he was actually sleeping, but he could reply to me! This was the first time I saw a sleepwalker.

What is sleepwalking?  

Sleepwalking refers to somnambulism or noctambulism, people in deep sleep will walk or perform other activities including eating, talking or cleaning. Some activities can be dangerous such as driving or even homicide.

How to explain sleepwalking?

There are 5 stages of sleep during a sleep cycle which lasts 90 minutes. During the first four stages, we have non-rapid eye movement (NREM) sleep, and rapid eye movement (REM) sleep occurs during the fifth stage. The sleepwalk usually occurs at stages 3&4. During this time, our brainwave is the slowest and we are in the deepest sleep. During REM sleep, our brain activity is much more active and our body muscles become temporarily paralyzed. Therefore most sleepwalking does not occur in REM sleep because we cannot walk when our muscles cannot move. People rise from their beds when their brain attempts to go straight from NREM sleep to being awake instead of completing the rest of the sleep cycle. Sleepwalking occurs mostly among children, some scientists think children are more likely to have sleepwalking because their brains are not fully developed. The growth hormones are the triggers causing the children to rise. It may also be related to inhibitory neurotransmitters. A neurotransmitter is called GABA which stifles the brains motor system. For adults, this neurotransmitter usually inhibits the body’s motion well. However, for kids, the neurons that release the neurotransmitter are not fully developed yet so their motor system may still be active and this will lead to sleepwalking.

Is it common?

  Dr. Plazzi and four colleagues did research about sleepwalking, their results showed:

  • Sleepwalking is most likely due to stress
  • Sleepwalking tends to run in families.
  • Sleepwalking occurs after 2-3 hours into sleep
  • Thirty percent of children between 5-12 experience at least one sleepwalking episode. Most children are between 4-6 years old.
  • Among 250 adults, one will have sleepwalks once a week.

As shown through this video, it talks about why we should not wake up a sleepwalker.

What should we do?

We have heard that waking up a sleepwalker will cause them to have a heart attack, brain damage. However, this is a misconception since there is no evidence that waking up a sleepwalker will cause them any harm. In fact, the one who tries to wake up a sleepwalker may be in danger because the sleepwalkers may react in unpredictable ways including attacking the one who tries to wake up them. Instead of waking up the sleepwalkers, what we are supposed to do is to gently lead them by the arm to guide them back to bed.

Why the Snooze Button is Anything But Your Friend

The weekend’s over, it’s Monday morning, and suddenly it’s time to go back to another busy week of work. Your alarm clock goes off and almost instinctively – like a predator just waiting to pounce on its prey – you hit snooze.

You know that feeling all too well, and you’re not the only one. A 2014 study revealed that more than half of the American population admitted to regularly using the snooze button. It turns out that what we see as only a few extra minutes of “much-needed” sleep is doing us more harm than good.

So, what’s actually going on when we hit snooze?

Most people who rely on alarm clocks experience sleep inertia, which is the state of grogginess and disorientation one immediately feels upon waking. The deeper the sleep stage you are waking up from, the more intensely you feel the effects of sleep inertia (and the more tempting it is to reach for that snooze button!). When we hit the snooze button and doze off again, our bodies are actually preparing to enter the start of another sleep cycle, making it nearly impossible to reach the final stage of the sleep cycle, REM (rapid eye movement) sleep, within a matter of minutes. This ends up leading us to feel even more exhausted throughout the day.

According to research and Human Sleep Science expert Professor Matthew Walker, being abruptly woken by an alarm clock triggers a “burst of activity [within the nervous system that causes] a spike in blood pressure and sudden acceleration in heart rate.” This means that repeatedly bargaining for more sleep is dangerously detrimental to our own hearts.

Is there anything I can do about it?

If you’re only realizing this now, it’s not too late to turn around and reverse this impulsive snoozing habit. Luckily for you, the road to recovery isn’t a difficult one. Perhaps set only one alarm at a later time rather than having multiple alarms to avoid interrupting your sleep or consider sticking to a consistent sleep schedule to train your body’s natural wake mechanisms. There are even sunrise alarm clocks that replace the blaring alarms with gradually brightening light to help us ease out of our slumber more naturally.

While we may have plenty of excuses to get a few additional moments of sleep in the mornings, we should have no excuse when our health and well-being is on the line.
