Over-aroused nervous system
In the evening you're still 'revved up' — the body won't drop out of alert mode.
This page isn't typically flagged for the selected profile — shown because you opened it directly.
Background
Sometimes the clock is fine but the body can’t come down from arousal. After a day full of stimuli, masking and task-switching, the nervous system stays in alert mode — racing thoughts, tense muscles, fast heart. What helps isn’t ‘forcing sleep’ but actively calming the body: slow breathing, lowering input, a wind-down ritual. (Be wary of the popular ‘polyvagal theory’ — a catchy framing but contested science; it’s the slow breathing that works, not the label.)
Methods for this mechanism

Slow breathing and an evening wind-down
Slow breathing itself has evidence; the 'polyvagal' branding is contested science.

Evening brain-dump and emotional check-in
Externalizing thoughts onto paper offloads working memory and quiets the racing thoughts that sustain arousal.

The nap game (rest without pressure to sleep)
Dropping the demand to sleep removes the performance anxiety that itself raises arousal and blocks sleep.

Scan the body and release tension (break the stress loop)
When you feel stressed, actively find the most tense muscle (jaw, shoulders, neck, belly) and consciously 'let it go'. Relaxing the body starves the feedback loop and stress drops — without fighting your thoughts.

Transition ritual into wind-down
A buffer and repeatable cue help the brain step down from arousal that can't be switched off instantly.

Co-regulation and soothing touch before bed
Oxytocin and pressure lower sympathetic arousal, shifting the system toward parasympathetic rest.
