It feels like it's been a long time since I last posted, but I will be posting every 2 weeks now with posts that are a little bit longer. For my first research round, I will be examining What is sleeping?, Why do we need sleep? and How many hours of sleep do we need for various ages? Before I get right into my round of research I must do a myth.
Your brain rests during sleep.
False: The body rests during sleep, not the brain. The brain remains active, gets recharged, and still controls many body functions including breathing during sleep.
To humans, we think sleep is when our bodies and mind are asleep, but science has proved that when were asleep our bodies are still functioning. Our bodies have to function during sleep or else we wouldn't be alive. Basically sleep is a natural state where our physical bodies are resting, but our minds are still working. (1,2)
Fun Fact: Most people end up spending 1 third of their lives asleep which is amazing considering humans tend to live in between 60 - 80 years. Can you imagine sleeping for 20 years of your life? (1)
Scientists aren't certain why we sleep, but there are theories like our brains need periods of rest. When I say rest I don't mean like sleep, but during the day our minds make connections through new experiences we face daily. At night, our brain decides which connections are important and remembers them while the brain discards the other ones. Overall sleep is a time where our brains can throw away waste and refresh for the next day. Another reason why humans need sleep is because we need energy to power through our day. Humans need a balance of sleep, a good diet and exercise to stay healthy and each item is as important than another. When we don't get a good sleep our bodies and mind are exhausted which result in us being tired and not be able to function like normal. Sleep can affect our school work and test marks for students which is key to having a good career. In my opinion, sleep is one of the things humans need because it has to ability to effect us in a negative way. (3,4)
How Many Hours Of Sleep Do We Need Based On Our Age?
As you can see above in the chart, as the age progresses the hours of sleep decreases. Which makes sense because the younger you are the more your brain is still developing and when you're asleep your brain does most of the developing. Of course, it is better to get more sleep because you will be better rested, but let's face it, most people probably don't get the amount of sleep recommended. I personally get 7 hours a night which is pretty close to my recommended hours, but I would like to know how many hours of sleep you guys get to see if teens are getting their 8 - 10 hours of sleep. (Chart Data and my own opinion)
For my next post, I'm going to look into medical issues that revolve around sleep (Insomnia, Sleep Apnea, Narcolepsy) and hopefully find some ways to help deal with the issues!
Thanks for reading my post and comments are always welcome.
