There is a "folk illness" in the Philippines called pasmá. There is no equivalent medical term in English or Spanish.
The symptoms of pasmá are trembling hands and sweaty palms occurring after strenuous use of the hands in manual labor. Farmers who work in the fields dragging plows, women who handwash laundry, pianists, and athletes frequently suffer from pasmá. Their hands become pasmado.

Popular folk remedies for pasma involve coconut oil, alcohol and urine.
Mothers often warn their children not to wet their hands or feet with cold water after sweating at play. You're supposed to rest first. Otherwise, your hands will grow out of control and they will be shaking all the time. You won't be able to work as a cameraman or photographer when you grow up because your hands will be unsteady!
From the Spanish word espasmo, meaning 'spasm'
