A walk through the stages of sleep | Sleeping with Science, a TED series

Did you know you go on a journey every night after you close your eyes? Sleep scientist Matt Walker breaks down the difference between REM (Rapid-Eye Movement) and non-REM sleep, what occurs during each stage of sleep -- and why it's important to get enough of both.

From the constant smile on this dude's face, I can say that he sleeps well.

I just cant start to think how good of a sleep this guy must be getting each day!!

When I take a nap, I always tell people “I need to go consolidate memories.”

I love this narrator. His voice is very clear and he seems interested in the topic

"It's during REM sleep that we receive almost a form of emotional first aid" (love this part!)

I screwed my shoulder up somehow last week. Man it hurt. I was going through other non-related pain as well...and for a couple of days in a row I ended up sleeping for 12+ hours and it was blissful. The second night of 12+ my shoulder pain completely went away and I was so grateful!
I use to fight sleep so hard. I hated it! Now I love my sleep and often drift off embracing it and appreciating it. That point when I start drifting after a long day...can feel legit magical. Very euphoric sometimes!

Wish our teachers could teach us so simply just like him

Sleep helps control our metabolism and weight, promotes stable moods, helps prevent cardiovascular diseases, boosts our immune system/function, increases knowledge retention, and helps us with long and short-term memory. Sleep is also essential for brain functioning.❤

"Let's take someone who typically goes to bed at 10pm, and they wake up at 6am"
Yes, yes... that's exactly what I do.

I get 8-9 hours every night. I never get sick amridiculously healthy, and it's not from other lifestyle factors (e.g. diet) being stellar. I'm convinced good regular sleep is the reason. It's importance cannot be overstated.
