Hi everyone,

This is my fourth round of research with my question “How does dreaming vary with age?”. For this round of research, I’m going to be looking at myths about dreams and sleep.

---------------------------------------------------------------------------------------------------------

Snoring is a problem common in men, but is not harmful

Generally for most people, snoring is harmless; however it could be a symptom of sleep apnea, a life threatening sleep disorder. It’s when your breathing continuously stops and starts. People with sleep apnea are often very tired during the day, even if they get a full night’s rest. (1,2,5,6)

You may cheat on the amount of sleep you get

When we don’t get enough sleep, it often builds up and becomes what is known as sleep debt. Overtime, if it becomes a massive amount of sleep loss, it can lead to different health issues such as high blood pressure.  It’s important to get between seven to nine hours of sleep every night. (1,5)

Teenagers falling asleep in class are lazy and have bad habits

Teenagers have an internal biological clock that keeps up awake later into evening and sleep in more in the morning.  School does often start early, which can interfere with this biological clock. They are at school while their body wants to be asleep. Teenagers need at least eight to ten hours of sleep as well and school being early doesn't always help them get that amount of sleep. (1,5)

Insomnia is just the difficulty of falling asleep

There’s not only the difficulty of falling asleep, but there are a few more symptoms as well. Waking up too early and not being able to fall back asleep, waking up multiple times during the night, and waking up feeling unrefreshed are more other signs of insomnia. (1,5)

Feeling tired during the day means you didn’t get enough sleep

There’s a condition called excessive daytime sleepiness which is when you feel really tired and drowsy all the time, even if you get more than enough sleep. It could be a sign that you have another sleep disorder or medical condition such as sleep apnea or narcolepsy.  It could be really dangerous because it puts you more at risk to be in a car accident, being injured because you aren’t as focused and you're tired. (1,3,5,6)

During sleep, your brain is resting

Your brain is still active during sleep, it’s just more so being “refreshed” and “recharged”.  It’s mostly your body that is resting while your asleep. We switch between rapid eye movement sleep (REM) and Non-REM, and in both stages of sleep, our brain is active. During NREM, stage one is drowsiness, when you could be woken up easily, and then it goes to "deep sleep" stages three and four, when it’s harder to be awoken and where the most positive effects of sleep happen. During REM, it’s where all the dreaming happens as well as having an increased heart rate and breathing, muscles relax, and our eyes move back and forth under our eye lids.(1,4,5,6)

If you wake up in the middle of the night, it’s best lie in bed and wait till you eventually fall asleep again.

As I mentioned earlier, waking up and not being able to fall back asleep is a symptom of insomnia.  Counting sheep or relaxing thoughts and images might help you fall back asleep again, but if you don’t fall back asleep in around 15-20 minutes, it’s best that you get up and do a relaxing activity, such as reading or listening to music.  You should avoid watching the clock too as that could make you more stressed, thus making it harder to fall asleep. Once you’re drowsy again is when you should try and go back to sleep. (1,5,6)

When children do not get enough sleep, it will show the next day

After not getting enough sleep, the symptoms are different in children than in adults. In children, they will be more active, have an extremely low attention span, and have issues behaving. (6,7)

Not everyone dreams

The average person has around 3-6 times a night, they just simply do not remember the dream.(8) A lot of the time, we forget our dreams instantly. Sometimes you’ll wake up and remember your dream but then immediately forget a second after.  It’s still not completely known why we forget our dreams, but one theory is that we don’t concentrate hard enough on them while we are sleep. Another is that norepinephrine (a hormone associated with memory) is turned off while we are asleep so our brain isn’t recording the night visions into memories. However, people who find their dreams to be more important, often remember a lot more than those who don’t - probably because their brains are more motivated to pay attention. (9)  People also tend to remember the dream more if it’s a nightmare because how real and bothersome it can feel.(10)

Hey Rhea! 

Lovely post. These myths truly surprised me, but I have also heard certain of them before. Also, I remember my friend mentioning "Sleep debt", but I never caught on! It's interesting to learn how the build up of hours you have lost sleeping can have negative consequences overtime, such as a weakened immune system. This can explain why in proportion, sleep helps to fight off colds or sickness!  

Overall, I learned quite a bit of new information! I'm wondering where your next cycle will take you, if you will still continue on the primary topic of dreams. Can't wait! 

Good job!

Hey Rhea,

Wicked post, again. I really appreciated all of the informative charts and pictures you included in your research this round, they helped me to really soak up the information you had written. I appreciated the tidbit of information you included on what to do when you wake up in the middle of the night. As someone who always lays in bed when they wake up in the middle of the night, I was surprised to read that after 15-20 minutes you should do something relaxing. Neat!

If you choose to continue research on dreams and sleep into another cycle, maybe you could look a bit into nocturnal animals and how their sleep cycles work, what makes something nocturnal, and why things are nocturnal. 

I look forward to seeing what you research next, keep up the good work :-)

Hi Rhea, 

Awesome research round. I liked how you added all these photos to help with comprehension, and I particularly enjoyed reading your section on snoring. What I find is that some people have this misconception that snoring is bad for you. Furthermore, I found it interesting that when the airway is blocked, it can create the “snoring” sound. Wow, I guess you learn something new every day! I also found your section on how not everybody dreams to be interesting. It’s intriguing how our brains don’t concentrate hard enough on our dreams when we’re sleeping and that hormones such as norepinephrine get turned off. I was wondering to what other hormones get turned off while we sleep and why their levels decrease. Perhaps you could look into that in your next round? 

I have a question about sleep debt. As you mentioned, when we don’t get enough sleep, it often builds up. Could you potentially sleep five hours for a couple of nights and then sleep 14 hours to take away your sleep debt? ...Or would that not work? Even so, I loved reading your post this week! Keep up the hard work!

Hello Rhea,
A very interesting round! I really liked all of the facts and tidbits and the way that there was always a picture associated with each of the points. The fact that these are very common myths though surprised me, like “During sleep, your brain is resting”. The more interesting one though I found to be the first one, about snoring. I always wondered why we snore, sleep apnea being one the causes make it interesting cause it causes problems with our breathing. I wonder though what the most common myth of all is though about sleep if there is one most common. I remember from my research into sleep, that there Is very little actually known about why we sleep and why every animal does it. It’s one of those things in life that we both know and don’t know at the same time. I can’t to hear more about dreams and how they connect to sleep in your presentation!
