SALT LAKE CITY — One of the best things athletes, coaches and society can do to help prevent and treat mental illness in sports is to get rid of the stigma surrounding it. And, said Dr. Jason Hunziker, that's exactly what Simone Biles did by withdrawing from the final individual all-around competition at the Tokyo Olympic Games. Hunziker — a leading sports psychologist and division chief of adult psychiatry at Huntsman Mental Health Institute — recently participated in an international think tank on athlete mental health and helped draft recommendations specific to Olympic athletes. He stated that Biles, the most decorated American gymnast and defending Olympic champion, "should be a model for the rest of us" that "it's OK to step back and take inventory."
