Why track heat response
Regulations focus on symptoms only after they become critical. Heat strain builds invisibly. By the time symptoms appear and can be reported, the window for prevention is at risk of passing.
Guidelines look at the weather and every body reacts differently. Guidelines continue to improve —but weather is just one measure, and it's applied to everyone the same. Hydration, acclimation, and fitness all vary—day to day, athlete to athlete. One-size-fits-all guidelines can't account for that.
Core body temperature is key. Core body temperature is the most important internal measure of heat strain—it is still measured in the pros with a rectal thermometer. There's been nearly impossible to monitor in real time. Until now.
➡ A lightweight, non-invasive sensor pairs with an app to give you instant insights into how your body is responding to heat.

What parents are saying
Lacrosse
We travel for lacrosse tournaments year-round. We never know how the weather will impact my son when we're in different climates. HeatSense shows us how he's actually responding in each place. What works in 85-degree humidity can be worse than 95-degree dry heat. — Terra S., parent of club national lacrosse team athlete
Softball
"Tournament weekends often mean several games in two days. I'm that mom constantly asking 'are you drinking water?', and my daughter is tired of hearing it. HeatSense changed everything. Now we both see the same data. I have peace of mind knowing she's taking care of herself, and she has proof when she tells me 'Mom, I'm fine.'"
— Becca S., parent of competitive softball player
Golf
"Golf rounds are 4-5 hours in direct sun with minimal shade. Depending on the day, fatigue can set in and my son's game can struggle on the back nine. HeatSense shows him what's actually happening—is he tired or is heat affecting his performance? Now he hydrates more strategically and knows when he needs to find shade between holes."
— Randy F., parent of junior golfer
Tennis
"Tournaments are brutal—and the heat starts in March now. HeatSense helps my son track his heat response patterns so he knows what works for his body. He's learned he performs best when he stays in a certain range. Now he manages himself proactively through every tournament."
— Jamie G, parent of USTA tournament player
