Jung SY, et al. - In patients with mild to moderate obstructive sleep apnea, researchers assessed the association between issues related to sleep hygiene and clinical symptoms. Findings suggested an association of inadequate temperature and humidity, drinking alcohol before sleep, and emotional excitement or arousal with symptoms of mild to moderate OSA, among sleep hygiene-related conditions. The presumption that symptom relief could be experienced in patients with mild to moderate OSA if they are trained to correct lifestyle habits to maintain adequate sleep hygiene-related conditions was supported in the findings.
