Shout out to The Postal Service. Everyone knows they should probably sleep more, but you know how weeknights are. You’re tired of all the day’s crap so you stay up late just to get some chill time. But by the weekend you’re exhausted from doing that five days in a row, so you sleep in. Turns out, that’s a good thing. Researchers found that a longer snooze on the weekends can counteract the negative effects of sleep loss during the week, reducing mortality risk to the same level of those who sleep enough every night. So if your kids come barraging into your room on the weekends, you can tell them Don’t Wake Daddy… or he’ll die. Sorry, it’s hard to stay away from the melodrama on this one.
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.
