3🔍 Why it matters — what to watch for
A heatstroke measure triggered when the heat index (WBGT) exceeds the threshold. But for the bench it's a precious chance to openly relay instructions, and tactics often change right after. A longer stoppage is a ‘cooling break.’
On the call you'll hear“A hydration break here. What tweaks will the two benches make in this minute?”
