Is pasma a real health concern or it's just a part of the Pinoy beliefs and culture?

When I used to workout at Fitness First, I asked the instructor if it's just fine to take a bath right after a rigorous workout. He said yes, and that I shouldn't worry about pasma because it isn't really a health concern after all.

Medically speaking, there's really no proof that "pasma" is real. It's a "folk illness" that's part of our beliefs and culture. :)
