TL;DR single test at best inconclusive but broadly said no evident benefit. Good randomisation but so many variables.
I am convinced the author is in a persisting out of body state.
Also, placebo is great!! I have reverse white coat syndrome, paying my GP attendance fee to have a nice doctor measure my BP consistently shows it better than when I do it at home.
Do you measure it in a chair similar to your doctor's office? I thought my couch was similar and I was careful to have my feet flat on the floor. But I "lowered by BP" by 10-15 by moving to the dining room table.
This is a self reported anecdata over many years. I do measure mainly on a couch, yes. Odd that reclining would be higher than sitting but I will try some variation. You'd think being more corpse like was net beneficial to BP
