There are two others which do old folks a world of good. The first oxygen therapy. You basically lie in a small chamber with Concentrated oxygen under pressure. Do that for an hour.
This therapy has been available for decades for heart attack victims whose hearts are not pumping very well.
But in recent years —oxygen therapy has been found to increase lifespan.
I’ve tried it. Basically, it makes me feel like I do after a good work out. And for similar reasons. After a good workout, my body is saturated with oxygen.
So if you’re not given to good workouts—this therapy will do. However, its expensive. Even the home devices are expensive.
The other therapy is red light therapy. I don’t know much about it—but I’ve seen several people on utube—whose opinions I respect—say nice things about it.
The prices of red light therapy devices are a similar to vibration therapy devices.
Fortunately, I do aerobic Heavyhands (and have since the 1980's), so I get a good aerobic workout even with just upper body work. Before the knee osteo, I used to have a small step machine, and I would do that simultaneously with HH. GREAT aerobic workout. Unfortunately, when the knee went, the stepper also did. Just couldn't use it.
Red light therapy? Hmm..... never heard called that !
It’s sort of therapeutic ( I guess! Depends on one’s POV!) going to those “Red Light Therapy Districts”.
