How does cosmic background radiation affect humans?

Answer 1

Probably, the CBR does not affect humans.

The explanation is that it's just a radio hiss. In general, radio waves do not damage tissue (if you are not in close proximity to the source, as they are non-ionic, meaning they do not alter DNA). There are many sources of radio waves, including TV broadcasts and cellular networks; they do not harm humans. An alternate explanation is that CBR was present when life first began on Earth, and the diversity of spices evolved with the presence of CBR.
