Can anobody give me a reason?

Question

as for why we sigh? Does it have to do with lack of oxygen or what.

Answer 1

Think about when U sigh. It's to me a reaction to something said. Something stupid, something U don't want to deal with or when it's drama. It has nothing to do with oxygen, it's more of a way of showing emotion than using words. I hope this helps or gives U something 2 think about.
