To investigate the effects of exercise stress on halitosis, we determined concentrations of cortisol and catecholamine in the blood and that of volatile sulfur compounds (VSC) in the expired gas. The experiments were conducted on healthy volunteers. All volunteers were measured for VSC (hydrogen sulfide, methylmercaptan, dimethylsulfide), cortisol and catecholamine (adrenaline, noradrenalin, and dopamine) before and after a footstool elevation movement. We found significant increases in hydrogen sulfide in the volatile expired gas and cortisol, adrenaline, noradrenalin, and dopamine in the blood in a comparison of before and after exercise. In addition, a significant positive correlation was found between hydrogen sulfide and adrenaline, hydrogen sulfide and dopamine. These results suggest that induced exercise stress is a factor that increases the concentration of sulfur compounds. In particular, the results strongly suggested that adrenaline and dopamine are involved in the increase of hydrogen sulfide.
