The Mystery of Exploding Head Syndrome: A Disturbing Sleep Condition
Originally Published 1 year ago — by National Geographic

Exploding Head Syndrome (EHS) is a mysterious sleep disorder characterized by loud, sudden noises experienced during the transition from wakefulness to sleep. While the condition is harmless and typically lasts less than a second, it can be distressing for those who experience it. Research into EHS is ongoing, with experts attributing it to neuronal misfiring as the brain shuts down awake-time sensory activity. Despite being named in the 19th century, the cause of these auditory hallucinations remains a mystery, and many affected individuals do not seek medical advice due to embarrassment or lack of awareness.
