Sleep and migraine
The inseparable relationship between sleep and headache has been noted for centuries. Scientists have attempted to describe this interaction based on regions of brain anatomy and physiology similar to both conditions, yet the relationship remains to this day poorly understood. Migraine may be both caused and relieved by sleep, as well as being a cause of too much or too little sleep. Are sleep and migraine simply adversaries, or have these complex neurological states co-evolved for a reason, and if so, how can we capitalise on this relationship to alleviate suffering?
