Exploding Head Syndrome: The terrifying-sounding, harmless sleep disorder
Exploding head syndrome (EHS) is a harmless parasomnia in which you hear a loud, explosive noise in your head as you fall asleep or wake up; the sounds aren’t real, and others can’t hear them. The exact cause is unknown, with theories ranging from sudden brain electrical activity to inner ear issues and abrupt sleep-wake transitions, and it may be linked to medication withdrawal or genetics. Episodes vary in frequency and can disrupt sleep, sometimes accompanied by flashes, muscle jerks, or anxiety. There’s no specific cure, but symptoms can be managed with sleep hygiene, journaling to identify triggers, relaxation techniques, and, in some cases, medications used for parasomnias. Poor sleep quality linked to EHS may raise long-term health risks, so improving sleep is beneficial.
