Hello, I am learning about ss, to try to help someone. I just read about cells going sickle when oxygen is lacking. I realise its normal for some blood to be lacking oxygen all of the time but I would like to ask if anyone feels they have felt improvement by trying to create a environment rich in oxygen? (many houseplants) If anyone understands the process of how and why the cells sickle and can explain it in words I might understand? Also this person has been advised to do regular blood letting (removing some blood) has anybody had good or bad experience from this kind of thing? I have read some of your posts on environmental changes and different situations causing issues. Any tips on creating the best environment in the home?
