We studied headache associated with sleep apnea syndrome (SAS) in 36 SAS inpatients (mean age: 45.5 years; mean body mass index: 31.0 kg/m2; mean apnea–hypopnea index: 53.3/h). Thirteen of the patients (36.1%) complained of headache, which occurred in the morning in all cases. These 13 patients complained more of unrefreshing sleep than the patients without a headache, and their Epworth Sleepiness Scale scores were significantly higher (P < 0.05). Unrefreshing sleep and daytime sleepiness seem to be associated with morning headache in SAS patients.
