Understanding Alerts, Thresholds, and SMS Notifications

Updated on Sep 25, 2025

Understand how HeatSense delivers real-time biometric insights—helping athletes and coaches respond smarter under heat and exertion.

What Are Alerts?

Alerts are in-app notifications that activate when an athlete’s biometric data indicates elevated physiological load. They appear in real-time through the HeatSense mobile and web dashboard, giving coaches and guardians immediate insight into how the body is responding to heat and training.

  • Triggered by core temp, skin temp, heart rate, or Heat Strain Index
  • Delivered via the HeatSense app or dashboard
  • Fully configurable by athlete and activity

What Are Thresholds?

Thresholds are the set points that determine when alerts are triggered. HeatSense provides default recommendations to get you started—but because every athlete responds differently, thresholds should be customized based on individual physiology and performance response.

  • Example defaults: Core temp ≥ 102°F, Heart Rate ≥ 190 bpm
  • Editable via the HeatSense dashboard per athlete
  • Used to inform performance decisions—not as medical guidance

Note: HeatSense is not a medical device. It does not diagnose, treat, or prevent any medical condition. It delivers real-time insights to support smarter training and recovery decisions.

What Are SMS Notifications?

SMS Notifications are optional text messages that send vital biometric alerts to the mobile numbers you choose. They provide an additional layer of awareness for key stakeholders—like parents, trainers, or athletic directors—who may not be logged into the app.

  • Opt-in feature, managed in your settings
  • Can trigger on any biometric input—regardless of app thresholds
  • Ideal for high-priority alerts sent beyond your immediate team

SMS notifications supplement but do not replace in-app alerts. They expand communication to non-app users.
