If you are interested in this topic (inflammation prevention and reduction), take a look at the Wim Hof method (the Iceman). In its simplest form, it consists of two simple techniques: cold exposure and deep breathing with hyper-oxygenation. Anyone can do it, whatever their age or physical condition.
It is unlikely to help you, either, of course. At best, this is in the "studies suggest" but there also isn't anything robust to link it to, well, anything.
