As a parent of three kids who all play outdoor sports in Texas, I’ve spent countless hours at games and practices in the heat. At the opening of football season, I went to my son’s game on a day when it was 107°F. Sitting in the stands, I struggled to stay cool—and I couldn’t stop thinking about the kids on the field, wearing pads and running on hot turf. If I was overheating just sitting there, what was happening to them?

When I got home, I dug into the guidance used in youth, college, and pro sports. Most of it measures the environment and asks coaches and parents to react after problems appear. But every body responds to heat differently. Weather isn’t the athlete. What was missing was real-time visibility into how each player was responding in that moment.

I started HeatSense to change that. We combine core temperature, skin temperature, heart rate, and WBGT context to make an athlete’s heat response visible in real time—so coaches can manage load sooner, structure smarter practices, and keep performance from dropping when temperatures rise. Parents gain transparency. Athletes get the feedback they need to compete confidently in tough conditions.

Outdoor sports are becoming extreme environments. HeatSense is how we move from reaction to readiness—bringing individualized visibility to the sideline when it matters most.
