You have probably seen some of the latest research regarding sleep deprivation and the effects on the brain. Just one night of poor sleep can affect cognitive ability, mood, coordination, attention, decision making, etc. Absent enough rest, the brain functions at a much slower rate. We also have trouble concentrating, thinking clearly, and become more emotional. Have you ever noticed when you don’t get enough sleep, just finding your keys in the morning can be a struggle?
Why Sleeping Better Matters
Sleeping provides the brain with an opportunity to do a “rinse cycle” and get rid of all the toxins that have accumulated throughout the day. When you go to sleep, the flow of cerebrospinal fluid increase significantly, washing away the harmful toxins and waste proteins that build up between the brain cells during waking hours. These toxins have been linked with Alzheimer’s disease. Not only are you removing toxins, sleeping is also what enables your brain to consolidate and move information into long-term memory. It is this process that then allows the brain to recall and use the information to solve problems. One study showed that teenagers receiving just 18 extra minutes of sleep improved their grades in math and English.
Even the great inventor Thomas Edison recognized the power of sleep to stimulate new thoughts and ideas. He would put ball bearings in his hand and doze off. When they fell to the ground and the noise woke him up he was able to come up with new approaches. (p. 30-31 a Mind for Numbers by Barbara Oakley, Ph.D.) This explains why our greatest ideas come often come to us during our morning shower!
Ok, so now that I’ve bored you with the science of why it’s so important, what is it that prevents us from getting enough sleep? Unless you have Sleep Apnea or some other medical explanation, I’ve got one word for you…Screens! Screens can be anything from browsing the internet, social media, video games, watching Netflix, YouTube, etc. This issue of the endlessly pursuing electronic devices isn’t unique to our kids or millennials. It does not discriminate by gender, age, or ethnicity. I too have fallen into this pattern that takes away from my ability to do my best the following day.
More Than Just The Blue Light
While staring at screens during the day can be detrimental to our productivity and connection with actual human beings, it’s at night that it sets us up for disaster when it comes to sleep. It is so easy to get sucked into staying up way past our bedtime reading the news or catching up on Facebook. The blue light emanating from our devices tricks your brain into thinking its daytime. This keeps it in a higher state of arousal and hyper focus similar to the effect of caffeine or even amphetamines. You might as well just drink a cup of coffee right before going to bed.
“So, am I ok if I just dial up the orange light on my device at night,” you ask? It’s not just the blue light that causes problems. When you are watching or interacting with a screen, you are increasing the release of certain chemicals into the brain, like Dopamine. You are also stimulating natural reward pathways that feed the need for additional gratification… This is why it is so easy to say just 10 more minutes and then end up binge watching an entire season of Game of Thrones late into the night…Silicon Valley’s got you.
Sleeping Better | Where To Start
In our household, there are a no electronic devices in the bedroom when it is time to go to bed. Before implementing this rule, I would keep looking at work emails after climbing into bed which kept my mind racing well after turning off the light. Now I pick up a book instead and I’m fast asleep in ten minutes.
Our goal is screens off at least 30 minutes before bed for better sleep. Are these evening habits always executed perfectly? Nope, we have good days and bad. But I do notice a huge difference in how the end of my day sets me up for the next. When I sleep better, I feel better. I am more inclined to work out and go for walks. I am more patient with my kids when they are being knuckleheads. Even they freely admit that they are wrecked the next day when they slip and sneak a peek at their devices before bed.
So how are you going to close out the day? What is your evening routine? Are you maximizing your sleeping opportunity? Please let me know in the comments below. I would love to hear from you!
