To maximize glymphatic toxin clearing the lateral sleeping position is currently recommended.

This study was done on anesthetized rodents. In conversation I've heard support for sleeping on one's side (laterally).

This doesn't suit me physically. My shoulders are too wide. I twist into horrible positions and hurt the following morning.

That’s the side position. Lucky for me I sleep that way to make my head comfortable. I wonder if it is more refreshing to sleep that way too then?

Myself and all my three children from birth have been belly sleepers. Never slept a wink until they could turn themselves over since they make you put them on their backs. Always thought it odd.

If I sleep anywhere but my side, my throat tries it’s darndest to choke me to death, on behalf of the sleep apnea. So it works great for me!

The position shown in the first link will eventually fuck up the shoulder though. Aim your arms downward if you're having shoulder problems.

ya it looks like potential tendon impingement/bursitis to me.

Any evidence to support this? A downward facing arm tends to be more internally rotated due to the weight on it, which is definitely a more prone position.

If a fucked up left shoulder counts as "evidence", sure. :-)

Doctor prescribed an MRI and then suggested a surgery (with a minimum of 6 months of recovery). I declined. Turns out it was my sleeping position. I used to sleep pretty much exactly as shown, except towards the morning my arm would also go under the pillow, further straining the shoulder. Now when I sleep I extend the arm slightly downwards. This was sufficient to eliminate symptoms.

Obviously this will vary based on anatomy. Do a simple experiment. Lay down in this position and see if you have tension in the shoulder joint. If you're muscular (I am), you will very likely feel it. That tension, applied 8 hours each night, will most definitely cause issues.

Isn't that considered not as good for one's heart? I thought lying on the back is best for heart health?

roll to the right - ok; roll to the left, pressure on the heart.

But sleeping on right apparently aggravates heartburn. (Is there some law of advice, that there is always equal and opposite advice?)

The downsides of having organs all over :). Any position might either stress the organs that end up on the bottom or encourage a less that ideal flow of fluids.

I guess YMMV. Some trial and error may be needed to see what works for you even if the theory says otherwise (heartburn is an easy one to spot).

I find myself sleeping in bellydown position.
