The sleep-deprived brain can mistake friends for foes

Time to get more zzZzzs.

A new UC Berkeley study shows that lack of sufficient sleep hinders our ability to accurately read facial expressions.

In the experiment, subjects could not distinguish between threatening and friendly faces after being awake for 24 hours. As a consequence, study participants interpreted more faces, even the friendly or neutral ones, as threatening when they were sleep-deprived.

“Consider the implications for students pulling all-nighters, emergency-room medical staff, military fighters in war zones and police officers on graveyard shifts,” said study lead author Andrea Goldstein-Piekarski.

“Insufficient sleep removes the rose tint to our emotional world, causing an overestimation of threat…” said co-author Matthew Walker.

I thought I could be fine on my own because what better thing to do than to learn to be okay with yourself alone? Well I was but now it’s like I want someone. Fuck being alone. I miss having someone to talk to. I miss being cared about and someone to make me feel loved. I miss the heated moments and all the giggles in between. Those late night conversations and butterflies fluttering in your stomach. It’s hard sometimes and being with someone just makes things a little bit easier you know?
