AI Insight
Teams at the World Cup are employing various cooling strategies including hydration breaks and cooling-gel vests to combat extreme heat, but physiologists and team doctors distinguish between methods that make players feel cooler versus those that actually lower core body temperature. The effectiveness of cooling interventions varies, with some providing only psychological comfort rather than true physiological cooling. Understanding this difference is critical for player safety in high-temperature competitions.
Why it matters
This research has direct implications for athlete safety in extreme heat conditions, particularly as climate change increases the frequency of high-temperature sporting events. Distinguishing effective cooling methods from those that merely provide perceived relief is essential for preventing heat-related illnesses in professional and amateur athletes.
Understand the Science
From booed hydration breaks to cooling-gel vests, teams are trying everything to keep their players from overheating. Physiologists—and one World Cup team doctor—say feeling cooler is different than cooling the body
