A bit slow, and long ( at 1 hour 52 minutes), but a nice summary interview with Dr. Roger Seheult (of MedCram) about things you can do to boost your immune function and increase prevention measures.
Vit-D about 4000 IU or some quality time outside in the sun, Vit-C, Zinc, hot/cold contrasting showers or baths, exercise, even “forest bathing” (that was medically tested and walking in a forest a couple of hours a week DID increase immune cell activity).
The wander through the immunity mechanisms involved, and the biochemistry somewhat. Also the history of various treatments (such as ‘artificial fevers’). Point out that Finland has as many Saunas as people, and also one of the lowest Chinese Wuhan Covid death rates. I’m also pleased to note that what I’ve always called an “artificial fever” (bundling up until you are hot and sweating) is apparently known to many cultures, and works.
Some of it is a bit dated, from January 2021, so he talks about hospitals being crowded in L.A. and such. A little bit preachy about vaccination, and doesn’t cover the potential downsides of this particular vaccination as much as I think it deserves, but he is a practicing M.D. treating patients and that will be the bias there.
In my opinion, a nice reminder of some of the lesser practiced things that improve your health and resistance to diseases. Avoiding stress is covered (including an experiment with students and final exams where they found MODERATE exercise reduced stress and illness, but no exercise and too much hard exercise made you more likely to get sick), time outdoors in the sun, a weekly walk in the trees / park. All good. In short, some amount of “Don’t worry, Be Happy!” IS IMPORTANT to health, and all the Fear Porn making people worry and fret indoors is just causing them to, literally, be “scared sick”.
