When I drink water, whether it's a sip or a gulp in front of a fan I get a very big, genuine headrush that makes me not breathe for a second. I've tried to explain this to some of my friends/coworkers, but nobody relates and says they don't know what I'm talking about.

Does anyone know what this is? It happens literally every time. At work I have a small fan on my station, and I have to turn away from it when I sip water or I'll be gasping and get that light headed feeling.
