Sleepless with Rage: How Anger Destroys Rest

Ever tried sleeping after a heated argument? Yeah—your nervous system doesn’t do bedtime when it’s angry.

Anger disrupts sleep by keeping your body in a hyperaroused state. Research from the University of Pittsburgh (2003) showed that individuals with high trait anger experienced significantly more sleep disturbances, including insomnia and poor sleep quality. Anger keeps cortisol levels high and interferes with melatonin production—your natural sleep aid.

Progressive muscle relaxation (PMR) can help. By intentionally tensing and releasing muscles from head to toe, you shift focus from emotional turmoil to physical release, calming the body and inviting sleep back in.
