Sleep and nocturnal breathing of individuals working over 1-week periods at high altitude: a cross-sectional polysomnographic study.

ABSTRACT:

Study objectives

To investigate objective sleep architectures, sleep fragmentation, and sleep-disordered breathing (SDB) indices in high-altitude workers rotating a week of altitude followed by a week of rest schedules from the Atacama Large Millimeter Array (ALMA) Observatory, Atacama, Chile.

Methods

A total of 122 high-altitude workers (males/females: 70/52) completed a polysomnographic sleep study at the Operation Support Facility (OSF, 2950 m). The majority of the participants (78 [63.9%]) were low-altitude residents. Most of the workers (74 [60.7%]) worked at the Array Operation Site (AOS) at 5050 m (work high) during the day and returned to the OSF to sleep (sleep lower).

Results

The ALMA workers had a sleep efficiency of 83.2 ± 10.3%, with a total sleep time of
