Are you familiar with sleep inertia?
It’s that groggy, slow feeling when you first wake up. According to a study, that blurry feeling you have when you first wake up is kind of like being drunk.
The feeling sometimes only lasts a few minutes, but its effects can linger for a few hours. The study tested the problem-solving abilities of people who had just awakened from eight hours of sleep. It turns out that the subjects performed most poorly during the first three minutes after waking up. There’s some evidence suggesting that the areas of the brain in charge of problem solving and complex thought take longer to wake up than other parts.
