I have been presented with the following conundrum. Either you sleep on your back and snore, or sleep on your right side and get acid reflux, or sleep on your left side and put a heavier load on your heart, thus weakening it.
I d not have or seek scientific evidence for the first two claims. I have (weak) empirical evidence to accept them as plausible (I do snore more on my back for instance). What I am asking here is about the third claim.
Does sleeping on your left side put such an extra burden of weight on your heart that it might be unhealthy?
