Question..- My stomach is extremely cold.... Why is that?

I exercise almost every morning..

I didn't know because I hadn't thought about it before.

My lower abdomen has been extremely cold these past few days...

It's hot outside... and somehow, it feels as cold as if I just washed my stomach with icy water...

Hmm.. I wonder why that is....

It feels like it's not like that right now when I touch it...

Maybe I only felt it more when I was exercising (walking)....
