Altitude Periodic Breathing Sleep
Altitude periodic breathing sleep disrupts rest with cyclic breath pauses at elevation—common early in acclimation and managed with gradual ascent and camp habits.
Altitude periodic breathing sleep is Cheyne-Stokes–like cycles of deep breaths then pauses common above roughly 5,000–8,000 feet until acclimation—often fragmenting sleep and feeling alarming to partners. Hydration, gradual ascent, and avoiding alcohol and sedatives at camp help; severe cases need clinician input.
Expect lighter sleep the first nights at ski or trek elevation.
Common questions
-
Is periodic breathing at altitude dangerous?
Mild cycles are common during acclimation. Seek help if breathlessness worsens at rest, lips turn blue, or confusion appears—that pattern suggests pulmonary or cerebral complications, not benign periodic breathing alone.
