Disclosed are a resonant wave frequency formulation for autonomic nerve relaxation and a control method thereof. An electrical wave generator generates an autonomic nerve resonant wave formulation. According to the autonomic nerve resonant wave formulation, the electrical wave generator outputs the electrical wave that acts on the human body, wherein the electrical wave is provided to produce first to sixth energy densities generated continuously by six frequencies during a first frequency action period, produce seventh to tenth energy densities generated continuously by four frequencies during a second frequency action period, produce eleventh to thirteenth energy densities generated continuously by three frequencies during a third frequency action period, produce fourteenth to fifteenth energy densities generated continuously by two frequencies during a fourth frequency action period, and produce sixteenth energy density generated by one frequency during a fifth frequency action period, such that the electrical wave can act on the human body to promote physical and mental relaxation of the human body thereby alleviating autonomic nerve disorder.
