In the first AMA you mentioned MS being its own category and mainly discussed Alzheimer's and maintaining cognition for healthy people to offset Alzheimer's risk. How about for people who already have MS? It's a very broad question, I know, but I'm interested nonetheless. I would assume most of the diet and excercise advice still stands, but what exactly should be done differently with regards to lifestyle in general if you do have MS? In particular what to be aware of as far as balancing neurological health and support and preventing immune overactivation (i.e. decrease risk of episode in RRMS or slow down neurodegeneration in other types of MS). I ask because I have recently diagnosed MS and have a very normal EDSS, if you don't stick me in an MRI you'd never know. Thanks!
What are the fundamentals in how sunscreen works to block UVA & UVB rays? How is SPF determined? Why do some individuals seem to respond differently to sunscreen (e.g., I can wear SPF50 & be fine for a couple hours, but my my husband needs to reapply more frequently)? What ingredients in sunscreen should we be on the lookout for & which should be avoided? What are the effects of the ingredients of sunscreen in our system?
