The Extreme Heat Policy activates when the Wet Bulb Globe Temperature exceeds certain thresholds. Measures include mandatory cooling breaks around the 30th and 75th minutes, extended halftime periods, and additional hydration stations.
In extreme cases, matches can be postponed or rescheduled. Player safety is the top priority, and the league works with medical staff to monitor conditions. Summer matches in cities like Houston, Dallas, and Orlando are most commonly affected.
