ABSTRACT
The scientific literature shows that the reduced oxygen supply (O2) induced by acute or chronic exposure to high altitudes stimulates the organism to adapt to new physiological and psychological conditions imposed by hypoxia. Sleep can suffer partial fragmentation due to exposure to high altitudes, and these changes can be responsible for impaired cognitive functions. Therefore, this study aimed to explore the relationship between hypoxia, sleep and cognitive functions. We conducted a literature review in the period from 1978 to 2020. In that way, we concluded that hypoxia can impair sleep patterns and, consequently, cognitive functions, including memory, attention, executive functions, decision making and reaction time.
RESUMEN
La literatura científica muestra que el suministro reducido de oxígeno (O2 ) inducido por aumentos agudos o crónicos en la altitud estimula al organismo a adaptarse a las nuevas condiciones fisiológicas y psicológicas impuestas por la hipoxia. El sueño puede sufrir fragmentación parcial debido a la exposición a grandes altitudes, y estos cambios pueden ser responsables de las funciones cognitivas deterioradas. Por lo tanto, este estudio tuvo como objetivo explorar la relación entre la hipoxia, el sueño y las funciones cognitivas. Realizamos una revisión de la literatura en el período de 1978 a 2020. Por lo tanto, se concluye que la hipoxia puede empeorar el patrón de sueño y, en consecuencia, el funcionamiento cognitivo, incluida la memoria, la atención, las funciones ejecutivas, la toma de decisiones y tiempo de reacción.
