Four minutes of cooling between innings—applied to the deltoid and forearm—may help pitchers maintain velocity, feel less fatigued, and stay sharper deeper into games compared to traditional passive rest. The benefit likely goes beyond the arm, as managing body temperature may preserve cognitive function and execution when fatigue typically sets in. Instead of just staying warm, this challenges pitchers to rethink between-inning routines as an active opportunity to recover and sustain performance.
