Your brain confuses "exhausted" with "relaxed"
You know the feeling: running all day, meeting after meeting, a thousand decisions. In the evening you drop into bed. You should fall asleep immediately, right?
The opposite happens.
Sleep researchers have found that strong tension can wind up your nervous system so much that it stays in alarm mode, even when your body is long past done. Your sympathetic system, your fight-or-flight system, takes over. Your parasympathetic system, the one in charge of rest, never gets a turn.
The result? Racing thoughts, inner restlessness, the feeling of being "wired" even though you are actually exhausted.
