Infographic on excess Internet use

Yep, there’s more on the “Internet changes your brain structure” issue. Check out the infographic on this blog–the author has looked into multiple studies that document that excessive Internet use affects the way the brain develops, and not always in a positive way. He linked to a few studies, like this one from Scientific American, that are investigating how continuous Internet use physically changes the brain. The conclusions reached are still inconclusive, though, and the debate still rages over whether constant Internet availability and the subsequent brain changes have net negative consequences.

There’s no doubt that we live in a more inter-connected age, and that information is flowing faster than ever. It’s been said, “getting information from the Internet is like trying to drink from a fire hydrant.” (Finding the original quote was interesting–the above link to the quote is the earliest I could find, from 2000.)  It may be inevitable that our brains will indeed wire themselves differently as it’s impossible to go back to a time without all that connectivity. I’m hoping for an ultimate “moderation in all things” type of response. I want the pendulum to swing back a bit and people to put down their electronic devices in order to more fully interact with one another in person. (The media could do its part by creating advertisements advocating a break from electronic data, but yeah, that’s not going to happen.)

Part of me wants to shake the collective world’s shoulders and entreat them to disconnect, just for a little while, once in a while. Part of me recognizes the futility of that dream. But I’ll continue to be a one-woman advocate for unplugging from time to time, if only to make sure that your significant other hasn’t been replaced by a robot. :o)

Sleep or the lack thereof

So, yeah, sleep. We’re not getting enough of it, either as adults or as adolescents. I listened to a story on NPR this morning about how lack of sleep is making employees cranky and less productive, making them perform at the level of mild intoxication. I’ve already championed the cause of taking naps, and the NPR story suggested that employers who provide “nap rooms” may boost productivity.

Sleep deprivation affects brain function, memory, heart health and makes people prone to depression, diabetes, and possibly Alzheimer’s disease. Also, “a brain that is hungry for sleep will get it, even when you don’t expect it.” (National Sleep Foundation)  Fall asleep in class much? What about during meetings?

All this is another good reason to turn off the electronic devices at a reasonable hour to allow ourselves more shut-eye. The effects of sleep deprivation have been fairly intensely studied, and it doesn’t matter if you are majorly sleep-deprived or only partially sleep-deprived — mood is affected, motor functions are affected, and a host of other physical and mental processes are affected, none for the good. Skipping sleep can be harmful, or even deadly, especially if you’re behind the wheel, which documents more than 100,000 car crashes a year due to drowsiness.

So turn off the TV, leave your phone downstairs, and get to bed in time to allow yourself 7-8 hours of sleep, the amount recommended if you’re an adult, or 9-10 hours a night if you’re a teenager. Reap the benefits and we’ll all be the better for it. (Yes, I need to follow my own advice…)
