My doctor recommended the book “Why we sleep”.
Last time I went in, I couldn’t sleep and got about 2 hours of sleep. So I told them to expect the blood pressure to be high. Hence the recommendation.
It’s available on Kindle. I bought the summary for $2. Plan on going back and buying the full book.
You mean last time you went in for a sleep study? I had the same experience...maybe 3 to 4 hours of sleep. I was not prepared for the amount of instrumentation, strange bed, lights, interruptions, noises, etc and just could not get to sleep. Then half way through the crappy sleep they woke me to slap on a CPAP machine. After that, they immediately jumped to the conclusion that I needed to be on the machine full time.
The past four months I've been analyzing my sleep with the data from the CPAP machine combined with a pulse oximeter, a wrist actigraph, and a sleep position sensor. I've learned a lot from all the data I've collected. I do a lot better at sea level than at 2,200 feet; stay away from all sleep meds; get to bed the same time every night; zero alcohol; decaf coffee morning only; lots of exercise. The effect of a mild elevation change really surprised me.
