And while we are on the subject - no, you should not inject or ingest disinfectants like bleach or rubbing alcohol into the body in any form - they will kill you. And there’s no mechanism for introducing UV light into the inside of the body - it would fry your innards (remember sunburns?). I’m waiting now for some poor sucker out there to die from attempting to act on these half baked ideas, like the fish tank cleaner couple.
Get a little sun and take your vitamin D. Get your medical advice from the doctors and scientists.
