ABSTRACT
High altitude (HA) mining operations are a very important business in Chile, but reduced availability of oxygen affects the sleep quality, increasing the risk of accidents. An important regulator of sleep-wake cycle is the hormone Melatonin, produced by pineal gland as a sleep inductor. The aim of this study is to evaluate the effect of high altitude (4,500 m) on the quality of sleep of workers undergoing to Chronic Intermittent Hypobaric Hypoxia (CIHH) using self-reported surveys of sleepiness and sleep quality, measurement of sleep apnea (using nocturnal oximetry) and serum levels of melatonin. The Desaturation index (ID4) results revealed higher HA scores compared to sea level (SL). Regarding melatonin levels, the results show that it is increased in HA versus SL and this increase would be related to oxygen saturation during sleep. These data link sleep quality in HA to its melatonin levels, suggesting that melatonin may be a potential biomarker for sleep quality.
