"Alexa breath affects my lungs during 3rd period, the odor is strong enough to melt steel" would be correct.
"The special effects in the movie affected my ability to judge what was real and what the director made up".

not like you need any more reassurance, but it's effect, because effect is always the noun, unless it can be directly replaced with "do" or "make"
