We are often warned not to take health advice from just anyone on the internet, because there a lot of folks out there trying to make money from telling you how you are doing something wrong. That goes for sleep positions as much as anything else, and there is no shortage of "experts" who will tell you how to do it, whether they are really experts or not. So which is really the optimal position to sleep in? And can you train yourself to do it the "right" way?
First off, remember that humanity has managed to survive for hundreds of thousands of years without worrying about sleep positions. But according to science, the most optimal sleep position depends on who you are and the state of your current health. Even then, it's most likely only going to make a small difference. Dr. Rachel Salas, a neurologist who specializes in sleep medicine, explains the differences in sleep positions.
