Most people feel sleepy, grumpy, or dopey when they haven’t gotten enough hours of sleep. A new study in the Journal of Behavior Therapy and Experimental Psychiatry puts forth a theory on why sometimes less sleep can also lead us to be more depression-y and anxious-y. Their research takes aim at a common symptom of those conditions known as repetitive negative thoughts (RNT), which is basically your mind being a jerk and not letting you stop thinking about bad things. Using eye-tracking technology, they showed volunteers positive, negative, and neutral images, and found that volunteers fixated on the negative images longer and more intensely than the neutral and positive ones. They blame a lack of cognitive resources caused by not enough sleep for their inability to filter negative thoughts.
Millions of Americans flocked home this week to pretend they like their families just long enough to get some of Mama’s cookin’ and get in a good nap before sprinting off to engage in the true worldwide holiday of Black Friday. Well it turns out we should throw turkeys another pardon for believing they’re the cause of the excessive sleepiness experienced after the feast. Sure, tryptophan is present in turkey meat, and that does convert into melatonin, but it can’t happen without a little help. The true culprit? All those carbs from the mashed potatoes, cornbread, rolls, and mac & cheese you know you splurged on. These basically put tryptophan in the fast lane for conversion into melatonin. Europeans, sorry if you understood none of the last paragraph.
Sleep deprived teens:
Ever roll out of bed and look in the mirror after a few late nights in a row and just think “Gross?” Unfortunately, you’re right. Everybody thinks you’re gross. According to a study by The Royal Society, acute sleep deprivation and looking tired are related to decreased attractiveness and health, as perceived by others. Researchers took photos of participants after both good and bad nights of sleep, then had those photos rated by strangers, judging the subject’s attractiveness, health, and trustworthiness. The images after bad nights of sleep scored lower on attractiveness and health, as well as the strangers noting they would be less likely to socialize with tired looking individuals. So go take a nap. InsightCity said it’s ok. How much do you sleep?
Turns out there might be somebody to blame when you can’t sleep at night. Snoring partner? Crying baby? Game of Thrones creators for making us wait forever for season 7? Nope, nope, and nope. Your parents. But not because they inflicted irreparable emotional damage by never buying you Legos. It’s because you may have genes that cause sleep issues. Scientists have recently linked two genes with sleeping problems. Research subjects with a mutant FABP7 gene sleep more fitfully at night and those with a CRY1 variant are found to have abnormal circadian rhythms. With more research, hopefully more effective sleep disorder treatments can be developed. Barenaked Ladies asked, “Who Needs Sleep?” Not this guy. He’s good.
