Brain Scans Reveal Why It Takes So Long to Wake Up in the Morning - Inverse
"Sleep inertia" is real, and caffeine won't help.
very morning, people sleepily drag themselves out of bed, wandering through a brain fog that seems to take forever to dissipate. Early risers will deny it exists, but evidence in a new paper in the journal NeuroImage suggests otherwise. The University of California, Berkeley team behind the study also reveal the one way to get through it.
The term for that cognitive fog is “sleep inertia,” but before the current study we’ve never been quite sure why people experience it, says Raphael Vallat, Ph.D., the lead study author and post-doctoral fellow at The University of California, Berkeley. In the paper, he proposes a reason why it exists: Even when the body is awake and moving in the morning, its brain is asleep in some capacity for some time after.
