  • Sleep and Smartphones:

  • Is chemistry keeping you awake?

  • It’s 1am.

  • You should be sleeping,

  • but youre glued to your smartphone,

  • catching up on the latest news,

  • facebook updates and tweets.

  • It turns out that the smartphones and tablets

  • that keep you connected and organized...

  • May also be keeping you awake.

  • See, our eyes perceive light

  • in a range of wavelengths.

  • Different wavelengths produce

  • different color sensations.

  • And those sensations help

  • tune your internal clock.

  • Here’s sleep researcher Brain Zoltowski.

  • One of the best biological cues we have to what

  • time of day it isis light. And it turns out

  • that blue light in particular is very effective

  • for basically predicting when morning is.”

  • And guess what puts out a ton of blue light.

  • Your ipad, your phone, your computer

  • emit large quantities of blue light.

  • That means when youre under the covers texting,

  • tweeting or playing your latest game obsession,

  • youre essentially telling your body

  • it’s morning!” Again.

  • What you want instead is more red light,

  • which is more abundant towards dusk.

  • And that will help your body basically recognize

  • It is now evening,

  • and I should be preparing for sleep.’

  • Your body gets that signal through melanopsin.

  • Melanopsin is a protein that undergoes

  • a chemical change when exposed to light.

  • This protein hangs out in cells called,

  • well, well let brian explain.

  • Theyre referred to as Intrinsically

  • Photosensitive Retinal Ganglion Cells.

  • It’s a mouthful.

  • Basically these cells are located

  • deep behind the eyes where youre going

  • to be able to get and collect light

  • through your normal process, but

  • it’s just not affecting basically

  • the same visual regions of the brain.

  • Rather, theyre more signaling through

  • to the Supercreasmatic Nucleus, called the SCN,

  • where our master clock is located.

  • That master clock regulates circadian functions

  • everything that tells your body

  • to wake up and go to sleep.

  • There’s still a lot we don’t know about sleep and how it happens.

  • So what can you do in the meantime to help reset your clock?

  • If we basically do

  • what our bodies naturally want.

  • Eating at the right time of day,

  • going to sleep when were tired.

  • Youll find that youll get

  • much more restful sleep.

  • So shut off the screens well

  • before you hit the sack. And

  • don’t follow this sleep researcher’s example.

  • I am a horrible example.

  • Despite knowing a lot about these processes,

  • every night I still fight

  • the urge to go to sleep.

  • I am most productive probably starting

  • at about 10pm at night.

  • So most of my research and work then

  • is being tried to be done at the time

  • period I’m supposed to be going to sleep.

  • Hey instead of hitting that snooze button,

  • why not hit the subscribe button

  • and get more chemistry fun

  • and facts from reactions.

  • Sleep well, internet.
