Why do i sweat so much?

im an asian girl who started puberty like 2-3 years ago, but just from running aroung 3-4 mph for about 3 minutes, i get really sweaty and it looks like i just got out of the bath tub or something. its embarrassing because its gross and is just abnormal. i dont get pit stains but my back, neck, and face looks like it has been drenches with oil or something. what can i do to stop sweating? and what is my condition?
