What reaction might someone with Acute Mountain Sickness experience during sleep?

Individuals suffering from Acute Mountain Sickness (AMS) often experience symptoms due to the reduced availability of oxygen at high altitudes. During sleep, one of the common reactions is insomnia, which can occur because the body struggles to adjust to the decreased oxygen levels. As the body attempts to regulate itself, symptoms like headaches, nausea, and sleep disturbances become more pronounced, making it challenging for individuals to achieve a restful sleep.

Insomnia can manifest as difficulty falling asleep, frequent awakenings during the night, or simply not feeling refreshed upon waking. This experience can be particularly distressing for those at higher elevations, where AMS may cause the body's physical responses to shift, resulting in an overall inability to maintain a normal sleep pattern. Other factors contributing to insomnia in AMS include anxiety and discomfort from physical symptoms, exacerbating the trouble in obtaining quality rest.
