Ask the ASA: Changing Sleep Positions

This time around, Dr. Neil Kline from the ASA addresses a question about frequently changing sleep positions:

I’ve noticed that my main comfortable position to sleep in changes from time to time. For example, I used to fall asleep in the soldier position but now fall asleep on my side. What could be the reason for these changes? Does anyone else have this? 
-Niressa

Contrary to popular belief, we change positions many times during the night. We are not stationary and static during sleep. We probably shift positions during the night in order to prevent pressure sores, because they can develop after just a few hours of constant contact.  Body position can also influence sleep in individuals with some sleep disorders. For example, obstructive sleep apnea is often worse while sleeping on your back. Because sleep is more fragmented in this position, it is believed that there might be a tendency for those affected people to sleep in other positions.
