My sister is unable to sleep in Durango Colorado. She sleeps fine at lower altitudes. She sleeps about 3 hrs per night, is diabetic-type 1. this is becoming a real problem. I am worried about her health being affected by the sleeplessness. She has not been tested for sleep apnea.
Hello, maybe she is having adjustment disorder to the new surrounding which might be causing her difficulty in sleeping. Advise her to stay active during evening by doing some mild to moderate exercises or going for a walk before sleep, so that body gets tired for a bit, and she may sleep well. Advise her not to sleep in afternoon and not to take in caffeine or alcohol before sleep. And if there are any breathing difficulties then consult your doctor for the same.
