Sleep deprivation makes you cranky, fat, and dangerous.
It also makes you gloomy.
Take a look at this finding, reported in a New York Magazine feature that is, as far as I can tell, the same as the third chapter in Nurture Shock by Po Bronson and Ashley Merryman:
“Perhaps most fascinating, the emotional context of a memory affects where it gets processed. Negative stimuli get processed by the amygdala; positive or neutral memories get processed by the hippocampus. Sleep deprivation hits the hippocampus harder than the amygdala. The result is that sleep-deprived people fail to recall pleasant memories yet recall gloomy memories just fine.” (p. 3 in the NYM article linked and p. 35 in the book)
Great. Fat, grumpy, and incapable of retaining joy.
I can’t wait to hang out with me, ‘cuz that’s a winning combination.
(On a related note, how do I not have a category titled “Holy Guacamole, I Need Sleep!”? My first didn’t sleep through the night until he was over Three. The second is not exactly on the fast track to quiet nights, with or without ear infections, teething, and gobs of physical exertion. So I filed this under everything except Yoga. I’m too tired for yoga.)
(Also? Go read Nurture Shock. There are chapters on praise, sleep, race, lying, gifted programs, siblings, teenagers, self-control, social skills, and language; all compelling, well written, clear, thoroughly researched and revelatory.) I’ll leave the superlatives to the cover matter, but suffice it to say I will finish it before I finish The Pale King. That’s huge, given how little reading time I have and how much I want to read DFW’s final novel. Go get it. Library, local bookstore, friend…I don’t care. Read. This. Book.)
