MARTINEZ RUIZ, M.  and  MARTINEZ GALDAMEZ, M.E.. Sleep under extreme environments. Sanid. Mil. [online]. 2011, vol.67, n.3, pp.310-316. ISSN 1887-8571.  https://dx.doi.org/10.4321/S1887-85712011000400010.

Human sleep is sensitive to the individual's environment. Heat and nocturnal cold exposures provokes reactions in SWS and REM sleep. Altitude and high pressure are deleterious to sleep, especially in non-acclimatized individuals. Jet lag is a recognized aeronautical sleep disorder that results from crossing time zones too rapidly for the circadian clock to keep pace. In their controlled environment, astronauts can sleep well in microgravity. The present article examines current knowledge of human sleep patterns under different environments: heat exposure, cold exposure, altitude, aviation and microgravity in space.

Keywords : Sleep; Heat exposure; Cold exposure; Altitude; Jet lag; Space microgravity.
