On a hot day in spring 2021, as the Columbia College Koalas softball players in South Carolina left the field at the end of an inning, athletic trainer Kenya Moore noticed a disoriented player. The player complained of dizziness, shortness of breath and muscle tremors. Suspecting possible heat stroke, Moore said she put her in an ice bath and called 911. As the player recovered and Moore examined the circumstances leading up to the incident, one thing stood out: The athlete had just switched her ADHD medication.
