What the World Cup Hydration Breaks Really Tell Us

I’ve seen the consequences firsthand as a parent on the sidelines. Have you ever noticed the shimmering waves of heat rising off the turf? That’s a playing surface that could be 10 to 30 degrees hotter than the surrounding air. During an early-season heatwave this spring, my daughter’s lacrosse game went ahead, even though the school’s softball game was canceled. The temperature was 93 degrees, not including additional heat from turf or the effects of humidity. The team had one sub, no shade, and no additional water breaks. Research shows heat hurts cognitive performance, including reaction time and decision-making. What unfolded wasn’t just a health risk; it was bad lacrosse: dropped passes, sloppy checks, and poor decisions. Playing in these conditions, without adapting to the heat, does little to make kids better players. It makes them less safe and less able to perform at their best.
