Effects of acute exposure to hypoxia on sleep structure in healthy adults: A systematic review
The sleep quality of lowlanders in hypoxic environments has become increasingly important with an increase in highland and alpine activities. This study aimed to identify the effects of acute exposure to hypoxia on the sleep structure of lowlanders and to analyze the changes in sleep indicators at varying levels of hypoxia. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Twenty-three studies were screened and included in the quantitative analysis. The results showed that acute exposure to hypoxia reduced sleep quality in lowlanders. Post-sleep arousal events and the percentage of N1 were significantly increased, whereas total sleep time, sleep efficiency, and the percentage of N3 and rapid eye movement sleep were significantly decreased in hypoxic environments. Acute exposure to hypoxia had the greatest negative impact on wakefulness after sleep onset (WASO). In addition, a larger decrease in sleep efficiency and higher increase in the percentages of N1 and WASO were observed when lowlanders were exposed to higher levels of hypoxia. This study clarifies the quantitative effects of acute hypoxic exposure on sleep in lowlanders based on original studies and explains the sleep disorders faced by lowlanders in hypoxic environments.
期刊介绍:
Sleep Medicine Reviews offers global coverage of sleep disorders, exploring their origins, diagnosis, treatment, and implications for related conditions at both individual and public health levels.
Articles comprehensively review clinical information from peer-reviewed journals across various disciplines in sleep medicine, encompassing pulmonology, psychiatry, psychology, physiology, otolaryngology, pediatrics, geriatrics, cardiology, dentistry, nursing, neurology, and general medicine.
The journal features narrative reviews, systematic reviews, and editorials addressing areas of controversy, debate, and future research within the field.
