Special Issue Information

Dear Colleagues,

Obstructive sleep apnea (OSA) is a prevalent but often underdiagnosed sleep disorder characterized by recurrent episodes of upper airway obstruction during sleep. This condition leads to intermittent hypoxia, sleep fragmentation, and significant physiological stress, contributing to a wide range of health complications. OSA has been linked to cardiovascular diseases, metabolic disorders, neurocognitive impairments, and decreased quality of life. Despite growing awareness of the condition, many aspects of its pathophysiology, diagnosis, and treatment remain subjects of ongoing research.

This Special Issue aims to explore the complex relationship between sleep and sleep apnea. We invite researchers from various disciplines, including sleep medicine, pulmonology, neurology, cardiology, psychology, and public health, to contribute their latest findings.

We welcome original research articles, systematic reviews, meta-analyses, and clinical studies that provide new insights into the mechanisms, consequences, and management of sleep apnea. By compiling high-quality research, this Special Issue seeks to enhance our understanding of sleep apnea and contribute to improved prevention and treatment strategies for affected individuals.

This study aimed to compare 4 weeks of cranial electrotherapy stimulation (CES) versus cognitive behavioral therapy for insomnia (CBT-I) in athletes with poor sleep quality pre-competition as measured by changes in daily mood state and physiologic parameters of sleep. Athletes with poor sleep quality in their pre-competition phase were recruited. Four weeks of CES and CBT-I were used to compare the effects on daily mood state and physiologic parameters of sleep. The participants were divided into a CES and a CBT-I group. The Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Profile of Mood States (POMS), nighttime heart rate variability (HRV), and sleep architecture of cardiopulmonary coupling (CPC) analyses were assessed before and after the interventions. Twenty-four participants (time to competition = 46.71 ± 11.21 days) completed the study. Decreases in PSQI and ESS scores were observed in both groups. A decrease in confusion and tension scores and improvement of sleep efficiency were noted after CBT-I (p < 0.05). Changes in light sleep (stages S1 and S2) and deep sleep (stages S3 and S4) were observed (p < 0.05), accompanied by alterations in HRV (p < 0.05). Both interventions for athletes experiencing poor sleep quality before competition had efficacy in improving sleep quality and reducing daytime sleepiness. CES could cause alterations in sleep architecture and autonomic nervous regulation, and CBT-I contributed to a reduction in negative mood states. This study is tiny and limited by the absence of a control group, which may introduce psychological bias, and future research should include control conditions and extended follow-up assessments to validate these findings.
