The article explores the paradox of feeling physically exhausted yet mentally alert due to chronic stress.It explains how modern stressors like work pressures, social media, and constant connectivity trigger a hyperarousal state in the brain.

Unlike ancient threats that demanded immediate action, today's stresses persist indefinitely, keeping the body's fight-or-flight response active.This leads to sleep disturbances as the brain remains alert despite physical fatigue.

Key points include the role of cortisol disrupting sleep rhythms, the impact of artificial light and screens on melatonin production, and how rumination exacerbates stress.

The piece emphasizes that this state is biologically rooted, not a failure of willpower, and suggests strategies like consistent routines and cognitive behavioral therapy to manage it.
