Alerts and Thresholds

Why Alerts Matter

Training in the heat pushes your body in unique ways. HeatSense Alerts give you real-time visibility into your physiological load—letting you adjust pacing, rest, or hydration before your body reaches its limit.

Alerts act like your internal dashboard light: they don’t stop the engine, but they tell you when it’s time to slow down or make a change.

Understanding Alert Levels

Each biometric metric—like core body temperature, heart rate, or Heat Strain Index—can trigger two levels of alerts with thresholds defined by you:

• Early signals that your system is beginning to strain. This is your cue to modify intensity, activate cooling strategies, or extend recovery intervals.
• A stronger signal that your body is nearing peak load. Training should pause, and recovery should begin.

Note: These thresholds are designed to reflect performance-relevant zones, not medical danger zones. They are meant to support smarter athletic decisions—not to diagnose or treat any condition.

Default Settings vs. Personalization

HeatSense includes default alert thresholds based on widely accepted performance markers. However, every athlete responds to heat differently—and that’s why personalization matters.

• Start with all alerts ON to learn your heat response patterns
• Caution Alerts can be fine-tuned over time based on your training feedback
• Critical Alerts are designed as non-negotiable red flags and should stay enabled

Why Real-Time Feedback Changes the Game

Without real-time biometric feedback, heat strain is invisible—until it’s too late to adjust. HeatSense lets you make the call in the moment, helping optimize effort and recovery based on how your body is reacting, not just external conditions.

Reminder on Physical Symptoms

HeatSense is not a medical device. It provides data-driven insights to help guide training. If you feel lightheaded, disoriented, nauseated, or otherwise unwell, stop activity and seek medical care. Listen to your body first, and always prioritize how you feel.
